SELFJECTOR Instruction Manual Operation Manual1 1-3
1.3 Safety precautions
! WARNING
The bowl of SELFJECTOR produces a large centrifugal force when it rotates. Wrong handling is very
dangerous. Pay utmost attention according to the manual for operation, disassembly, reassembly,
maintenance, checkup, etc. Use of non-genuine parts might damage SELFJECTOR or impair human
safety. Be sure to employ genuine parts.
Perfectly assemble.
Many points of SELFJECTOR are connected by screws. When assembling, make sure tightening is
complete. Running with poor tightening is very dangerous. Doubly make sure of secure tightening
particularly of:
(A) Bowl nut
(B) Disk nut
(C) Cap nut of Vertical shaft
(D) Set bolt of Frame cover
(E) Lock nut (hexagon) of Inlet pipe
Be sure that tally marks of the bowl and other so marked parts are aligned.
If the tally mark is excessively mis-aligned when the Bowl nut is tightened, contact our company or
service agency.
Immediately stop if vibration is excessive.
Vibration of SELFJECTOR is caused by unbalance, ship oscillation,
SELFJECTOR installation, etc. If the vibration is excessive, immediately
stop SELFJECTOR without discharging sludge.
Then, check for the cause and take necessary corrective action to ensure
safety before restarting SELFJECTOR.
To be more specific, if the vibration at the point A of Fig. 1-1 exceeds
100 μm (peak to peak) at rated speed, stop SELFJECTOR.
Even if readings are below 100 μm, continuous cruising ship vibrations
4-5 times higher than registered when external vibrating forces are small,
such as when the main engine is not in operation, could adversely affect
the durability of SELFJECTOR. In such case, stop SELFJECTOR
immediately. Then, check for the cause and take necessary corrective
action to ensure safety before restarting SELFJECTOR as described
above.

Operation Manual1 2-2 SELFJECTOR Instruction Manual
2.1 Gear pump
The gear pump feeds feed oil to the purifier. Mounted on the horizontal shaft of the purifier via a safety
joint, it is driven by the motor for the purifier.
The gear pump can be selected to match a particular treating capacity.
Instead of the gear pump, a separate pump may be used.
2.2 Oil heater
Installed midway between the gear pump and oil purifier, the oil heater warms feed oil fed by the gear
pump to an optimum treating temperature. The heater is classified into steam and electrical types. The
steam type is provided with a temperature control valve and the electrical type with a thermostat to
control the temperature.
Before oil is treated by the oil purifier, it must be heated up to a certain temperature according to the
particular oil viscosity and nature.
2.3 3-way cylinder valve
The 3-way cylinder valve is a pneumatically operated selector valve and feeds feed oil to the purifier.
When starting, stopped or discharging sludge, it is changed to return the oil via the bypass piping to the
tank.
2.4 Multi- Monitor (MM)
The Multi-Monitor forms an integrated detection system with a Leakage Monitor, a Discharge Detector
and a Water Detector. It has displays to indicate the operational status data of SJ-G series
SELFJECTOR such as flow rate, temperature, pressure and speed. This instrument contains a serial
board (RS485) that enables communication with the control panel.
2.4.1 Leakage Monitor Function (LM)
The Leakage Monitor detects a leakage of treated oil from the bowl's sludge outlet or heavy liquid
output by means of a pressure sensor and delivers an alarm signal to the automatic control panel via
the Multi-Monitor. The pressure sensor is located on the light liquid outlet-side bracket of the
SELFJECTOR and normally maintained under a certain level of pressure by means of a pressure
control valve. When a leakage occurs, an ensuing pressure drop is detected by the pressure sensor
and an alarm signal is sent to the automatic control panel.
2.4.2 Discharge Detector Function (DD)
The Discharge Detector monitors the horizontal shaft speed by means of a proximity sensor and
determines whether or not sludge discharge has properly taken place by means of an input data
comparison circuit. When abnormal discharge is detected, an alarm signal is issued to the automatic
control panel via the Multi-Monitor. In addition to this alarm output function, the Discharge Detector of
the partial discharge type purifier has a display function to tell whether or not the sludge discharge is
optimal for partial discharge adjustment.

Operation Manual1 2-3 SELFJECTOR Instruction Manual
2.4.3 Water Detector Function (WD)
The Water Detector is available in a pressure type and an electrostatic capacity type (option). The
pressure type is designed to monitor the level of water accumulated in the bowl by means of a pressure
sensor provided in the circulation line that returns some of purified oil to the feed liquid inlet. This way of
water detection is called "G-HIDENS system" to differentiate from the detection system with the
electrostatic capacity type Water Detector. The electrostatic capacity type, which is installed in the
purified oil piping of the purifier, is designed to work on the principle that capacitance (dielectric
constant) rises as oil increases in water content.
When the water content of purified oil exceeds an alarm trigger level, the Water Detector issues an
output signal to the automatic control panel for sludge discharge via the Multi-Monitor.
2.5 Starter
The purifier is started by the starter. It is stopped by a signal from the control panel when an automatic
stop alarm has been generated.
2.6 Control panel
The control panel automatically controls the cycle of purifying the feed liquid by purifier and discharging
the sludge. Upon receipt of output signals from various detectors via the Multi-Monitor, the control
panel stops the oil feed, then the purifier after sludge is discharged.
2.7 Alarm panel
The alarm panel changes over the 3-way cylinder valve through switching. When a Multi-Monitor
output signal is received during running, the feeding is stopped.

3 STRUCTURE of SELFJECTOR
3.1 General
Fig. 3-1 outlines the structure of SELFJECTOR.
The power is transmitted from the motor through the
friction clutch to the horizontal shaft and is further
increased in speed and transmitted to the vertical shaft
through the spiral gear mounted on the horizontal shaft
and pinion on the vertical shaft.
The vertical shaft is supported by upper and lower
bearings.
The bowl mounted on the top of the vertical shaft rotates at
the speed of the vertical shaft.
To supply feed liquid to SELFJECTOR, the suction pump
(gear pump) is connected to the horizontal shaft through
the safety joint. To deliver light liquid, the centripetal
pump (impeller) is built in the top of bowl.
In addition, heavy liquid is forced out by a similar
centripetal pump.
3.2 Drive unit
3.2.1 Vertical shaft section
The revolution speed of the horizontal shaft is increased by
the vertical shaft pinion gear and the vertical shaft rotates the
bowl mounted on its top. The vertical shaft and bowl are
supported by upper springs and leaf springs radially
incorporated at 6 points on the upper bearing section and
lower springs in the lower bearing section so that they can
stably rotate.

Operation Manual1 3-2 SELFJECTOR Instruction Manual
3.2.2 Horizontal shaft section
Between the motor and horizontal shaft, the
friction clutch is provided.
The horizontal shaft is supported by 2 ball
bearings built in the bearing housing (3) and
bearing housing (4). Between them, the spiral
gear is mounted. The bearing housings (3) and
(4) are provided with oil seals to avoid gear oil
leakage.
The horizontal shaft is directly coupled with the
gear pump by the safety joint.
3.2.3 Brake
By springs, the brake linings are pressed against the outer surface
of friction pulley to perform braking.
Use the brake only when quick stop is absolutely required in
emergency, for repair or checkup. For normal stoppage and not in
emergency, refrain from braking and allow the rotation to stop
coasting.
3.2.4 Friction clutch
A friction clutch is used for gentle starting and acceleration, thereby
preventing the motor from being overloaded.
The motor shaft has a friction boss provided with a friction clutch and
the horizontal shaft has a friction pulley. After starting, the motor
instantly turns at critical speed, the friction clutch lining is pressed
against the internal surface of the friction pulley via centrifugal force and
the power is transmitted to the friction pulley (horizontal shaft side) as
the friction pulley and lining slip with each other.
Normally, the bowl of small-size SELFJECTOR (SJ10G - SJ30G)
reaches its rated speed of rotation in less than 5 minutes, and
middle-size SELFJECTOR (SJ50G - SJ70G) and large-size
SELFJECTOR in less than 10 minutes.

Operation Manual1 3-3 SELFJECTOR Instruction Manual
3.3 Bowl
3.3.1 Structure of bowl
The bowl vessel mainly consists of body, hood and nut. The bowl incorporates separation chamber
composed of disc (1) and top disc and distributor, which distributes feed liquid from the bowl inlet to the
separation chamber uniformly.
There is a main cylinder, which slides vertically by water pressure to discharge sludge separated and
accumulated on the inner wall of bowl during operation.
At 2 points on the outer periphery of bowl, there are pilot valve assemblies for controlling the main
cylinder slide.
When feed liquid introduced through the feed liquid inlet through the distributor to the separation
chamber passes through the gap between discs (1), solids and water are separated and purified oil is
continually delivered outside by the centripetal pump (light liquid impeller) located on the top of bowl.
Separated water is continuously discharged outside through the heavy liquid impeller.
Gravity disc
For purifier operation, the interface for separating light liquid and heavy liquid in the bowl must be held
to within a certain range. On SELFJECTOR, gravity discs with different inner diameters are used
according to the gravity of oil to be treated, thereby changing the interface position.
Select an optimum gravity disc according to "Gravity disc selecting procedure" in Operation manual 2.
※:For the HIDENS specification, being for clarifier operation, requires no change of gravity discs.

Operation Manual1 3-4 SELFJECTOR Instruction Manual
3.3.2 Discharge mechanism
Total discharge is as follows.
ⅰ Purifying operation process
A centrifugal force acting on the pilot valve seals the
valve seat and the water pressure chamber for closing
bowl is filled with operating water. The operating water
pressure pushes up the main cylinder to seal the main
seal ring for purifying operation.
Operating water for closing bowl is intermittently
introduced into the bowl closing water pressure chamber
for a given period of time during purifier operation. In the
water pressure chamber, the centrifugally generated
pressure of water that turns with the bowl is balanced with
the supplied water pressure told the water surface at a
certain level.
ⅱ Opening bowl process
Operating water for opening bowl is fed for a certain time to
the water pressure chamber for opening bowl. It partly
goes out through the drain nozzle. More operating water
for opening bowl is supplied and fills up the water pressure
chamber for opening bowl. As its pressure slides the pilot
valve toward the shaft center, the seal of valve seat breaks
and operating water for closing bowl flows out from the
bowl.

Operation Manual1 3-5 SELFJECTOR Instruction Manual
ⅲ Sludge discharging process
When operating water for closing bowl goes out, there is
no more force of pushing up the main cylinder that, then,
is pushed down by the pressure in the bowl. The seal of
main seal ring breaks and sludge is instantly discharged
outside the bowl.
ⅳ Closing bowl process
After the sludge discharge, operating water for closing
bowl is fed to the water pressure chamber for closing
bowl and, when it is filled up, the main cylinder is pushed
up to seal the main seal ring.
NOTE
In the HIDENS system specification, partial discharge is effected to let out water accumulated in
the bowl, which is basically the same as the total discharge mode, except that the main cylinder
opening duration is shorter.

Operation Manual1 3-6 SELFJECTOR Instruction Manual
3.4 Water supplying device
The water supplying device is provided under the bowl to supply operating water for controlling the
discharge of sludge from the bowl to each water pressure chamber (for opening bowl, for closing bowl).
Operating water for opening bowl is fed from section An in
Fig. 3-11 and enters the water pressure chamber for opening bowl.
Operating water for closing bowl is fed from section B and enters the water pressure chamber for
closing bowl.
Operating water for closing bowl is intermittently fed for a certain time during the purifying running.
Because operating water in the water pressure chamber for closing bowl rotates together with the bowl,
the pressure generated its centrifugal force and the pressure of operating water for closing bowl balance
and the water level stabilizes at a certain position.
NOTE
Operating water for closing bowl : Water for pushing up the main cylinder and closing
the sludge outlet.
Operating water for opening bowl : Water for lowering the main cylinder and
discharging sludge.

Operation Manual1 3-8 SELFJECTOR Instruction Manual
3.6 Purifier operation and clarifier operation
3.6.1 Purifier operation
The purifier operation refers to a separation into 3 phases or oil, water and sludge. It is most
commonly employed.
1. The high limit of specific gravity of oil to treat is 0.991 (at 15℃) practically.
2. For normal operation, the interface must be set to within a specified range by changing the
diameter of gravity disc.
3. Before introducing oil, water sealing is required so that oil fill not flow out through the heavy liquid
outlet.
4. The purifier has a heavy liquid outlet for continually discharging separated water.
Fig. 3-13 is the cross sectional view of the bowl of SELFJECTOR (SJ-G series) under purifier operation.
Feed liquid is introduced from the feed liquid inlet into the separation zone by way of the distributor.
While separated heavy liquid (water) and solids go to the outer periphery of the bowl, light liquid moves
inside through between the discs and is forced out by the light liquid impeller. Heavy liquid passes
outside the top disc and flows over the gravity disc to be discharged by the heavy liquid impeller.

Operation Manual1 3-9 SELFJECTOR Instruction Manual
3.6.2 Clarifier operation
The clarifier operation refers to a separation into 2 phases or oil and (water + sludge).
1. If the specific gravity of oil to be treated exceeds 0.991 (at 15℃) , clarifier operation with the G-
HIDENS series machine is recommended.
2. The G-HIDENS series machines ensure stable clarifier operation for fuel oils up to 1.01 (at 15℃) in
gravity.
3. Irrespective of gravity, the G-HIDENS series machines accept oils for treatment without adjustment
with the gravity disc.
4. The G-HIDENS series machines require no water sealing.
5. In the setup for clarifier operation, there is no heavy liquid outlet for letting separated water out of
the machine so that separated water cannot be continuously discharged.
The G-HIDENS system is designed to detect the accumulation of separated water at a predetermined
level by means of a presser sensor installed in the circulation line and discharge it out of the bowl. It
combines the feature of the clarifier which is leakage-free operation and that of the purifier which is the
capability of water separation.
Fig. 3-14 shows the cross sectional view of the bowl of a typical G-HIDENS system SELFJECTOR
(SJ-GH series) in clarifier operation.
Feed liquid is introduced from the feed liquid inlet into the separation zone by way of the distributor.
While separated heavy liquid (water) and solids go to the outer periphery in the bowl, light liquid moves
inside through between the discs and is discharged by means of the light liquid impeller. Some of light
liquid passes outside the top disc and is returned to the feed liquid port via circulation line by means of
the heavy liquid impeller. To make this take place, pressure (0.1 MPa) is built in the circulation line
through back pressure valve. Upon arrival of accumulated water in the bowl at the top disc outside level,
the circulation of light liquid is stopped with an ensuing drop in circulation line pressure. This pressure
drop (the sign of maximum water accumulation in the bowl) is detected by a pressure sensor, a sensor
output is transmitted to the Multi-Monitor and accumulated water is released from the bowl as a result.
While water is normally discharged in the partial discharge mode, total discharge with sludge can take
place, depending on the time spent for water detection.

Operation Manual1 3-10 SELFJECTOR Instruction Manual
3.7 Parallel operation and series operation
So long as the feed rate is within the actual capacity, 1 stage of purification suffices basically.
When, however, treating oil for which catalyst mixture, excessive sludge, etc. are expected, raising the
purifying effect is required utilizing spare machine(s).
In this case, the purifiers are subjected to either:
Parallel (parallel purifying) operation
Series (series purifying) operation.
When operating several machines as shown above, the parallel operation is preferable to, for its better
separating effect than, the series operation.

3.7.1 Parallel operation
For parallel operation, 2 or more SELFJECTORs are arranged in parallel.
Fig. 3-15 exemplifies piping for parallel operation.
NOTE
In the case of parallel operation with two units of SELFJECTOR, the two machines share oil feed
to the whole system half and half between them. Select the sizes of piping, with flow velocity
and pipe resistance taken into account, so that pipes one size larger in bore diameter are used
upstream of the inlet line branching point and downstream of the return and outlet line meeting
point, for example.

Operation Manual1 3-12 SELFJECTOR Instruction Manual
3.7.2 Series operation
! CAUTION
In case of a series operation by 2 SELFJECTORs, detach the gear pump furnished with the
latter stage SELFJECTOR from the safety joint because it is not used.
Do not use the oil heater for the latter stage.
For a series operation, the former stage is for purifier operation and the latter stage is for clarifier
operation usually.
In case of a series operation by 2 machines, a general practice is purifier operation for the former
stage and clarifier operation for the latter stage.
The feed rate must be the same as for a single operation.
Fig. 3-16 exemplifies piping for a series operation.
NOTE
In the series operation, when the first-stage SELFJECTOR enters into the discharge process, oil
feed to the second-stage SELFJECTOR does not take place (as is the case with stop by an alarm
signal) in the meantime. The second-stage SELFJECTOR, therefore, requires an interlock
system to prevent the Multi-Monitor from issuing a false Leak Monitor output signal. (For general
description and working principle of the Leak Monitor, refer to Section 6.2.)

Operation Manual1 6-6 SELFJECTOR Instruction Manual
6.2 Leakage Monitor Function (LM)
6.2.1 General
The Leakage Monitor Function of the Multi-Monitor is a protective
device that detects:
Leakage of treated oil to feed liquid outlet
Leakage of treated oil from bowl's sludge outlet because bowl is
not properly closed
attributable to any reason and notifies it to SELFJECTOR control
panel via the Multi-Monitor to minimize the loss of treated oil.
6.2.2 Operating principle
The pressure sensor installed on the light liquid outlet connecting
piping of SELFJECTOR monitors the pressure at all times and if, for
any reason, the pressure has dropped when the flow has decreased
from a normal rate, deems treated oil is out-flowed and outputs an
error signal. Use of a precision pressure sensor allows to detect a
large leakage flowing to the heavy liquid side as well as a slight
leakage due to poor bowl opening.
In the normal running, pressure control valve that is arranged on the treated oil outlet piping adjusted so
as to apply a certain pressure. If, on account of accidental leakage of purifier, the pressure has dropped
below an alarm trigger or lower limit level, an alarm is outputted.
NOTE1 To prevent a false alarm, when actual back pressure, light liquid outlet pressure, falls below the alarm trigger or lower limit level, the Leakage Monitor will not issue a "Leakage" signal until after a certain period of time. The alarm trigger pressure is averaged by the CPU in the Multi-Monitor to follow with actual back pressure that is fluctuated by pressure pulsation at the light liquid outlet.

Operation Manual1 6-7 SELFJECTOR Instruction Manual
Delay Timer
After starting the feed, the light liquid pressure rises gradually. To prevent an alarm from being delivered
during the period where the pressure achieve set pressure, a delay timer is provided.
Hold Timer
As soon as the pressure has dropped below the alarm pressure while feeding, the timer for feeding starts
counting and, if the time is up, delivers an alarm. If the preset pressure level is recovered while counting, the
timer resets itself.
NOTE
Be sure to adjust and set the light liquid side delivery pressure.
(Standard value : 0.15 MPa {1.5 kgf/cm2})
Since its operating principle is such that this instrument needs a steady pressure independent of
the piping pressure loss downstream from SELFJECTOR for proper detection, adjust the pressure
control valve to maintain the instrument under a necessary level of back pressure during the
operation.
When a light liquid delivery pressure beyond the standard level is required, refer to "Leakage
Monitor (LM) " in the Operation Manual 2.
6.2.3 Connecting with control panel
To avoid erratic alarms, "feeding" signal is inputted from the automatic control panel or alarm panel so that no
alarm could be outputted unless when "feeding".
NOTE
For a manual type, the feeding signal contact is normally closed to simulate feeding. To avoid a
false alarm during sludge discharge, therefore, turn off the "MM Function Switch" on the starter
panel before sludge discharge, then turn it on again after feeding is started.

6.2.4 LED display
1. "Pressure adjustment"(yellow)
The pressure adjustment LED (yellow) flashes when light liquid pressure varies by ±15% or less from the
Multi-Monitor setting and stays illuminated while the variation is less than ±3%.
Adjust the back pressure regulating valve so as to just light the LED when feeding.
(Set the back pressure to the standard setting for light liquid pressure is 0.15 MPa (1.5 kgf/cm2)).
2. "Leakage display"(red)
When a leakage is detected, the Error LED (red) on the Multi-Monitor panel and Leakage signal output LED
(red) above the boards in the Multi-Monitor are illuminated and an alarm is issued to the control panel at the
same time. The oil purifier is stopped as a result after sludge is discharged.
Specifically, the Leakage LED is lit when:
Pressure fails to reach a constant level before the delay timer is up.
Pressure falls below the alarm trigger or lower limit level and fails to return to a constant level before the
hold timer is up.
For self-diagnosis, in the case of an abnormality with the light liquid sensor described below, the "Light Liquid
Sensor Abnormal" LED (red) in the Multi-Monitor is illuminated, with "Error" and the corresponding error
identification number displayed in the upper and lower seven segment displays, respectively, and an alarm is
issued to the control panel at the same time. The oil purifier is stopped as a result after sludge is discharged.
An extraordinarily high voltage (equivalent to 0.45 MPa {4.5 kgf/cm2}) is detected at the pressure sensor.
NOTE
When the self-diagnosis function is actuated, the Multi-Monitor holds "Error" and error identification
number in display, which cannot be cleared until power is turned off.
After the cause is identified and eliminated, reset by turning power off, then on.

6.2.5 Routine running
Normally, keep the LM alarm output switch in the Multi-Monitor
in the ON position.
NOTE1
The △P(pressure drop) value in regard to the Leakage Monitor function varies in response to the
changing level of actual back pressure. Therefore, it needs no adjustment even if light liquid side
pressure differs from its initial set value unless the deviation exceeds 0.2 MPa (2.0 kgf/cm2).
NOTE2
On the method of the back pressure regulating valve, make adjustments correctly in accordance
with appropriate procedures described in " Leakage Monitor Function (LM) " in the Operation
Manual 2.
Wrong setting or adjustment may cause a false leakage alarm.
6.2.6 Items to adjust
Normally, the back pressure regulating valve requires no adjustments after set up at once, except in the
following cases. For the adjusting method, refer to "Leakage Monitor Function (LM)" in the Operation Manual
2.

Operation Manual1 6-11 SELFJECTOR Instruction Manual
6.3 Discharge Detector Function (DD)
6.3.1 General
The Discharge Detector Function (DD) of the
Multi-Monitor is a protective device that monitors sludge
discharge from the SELFJECTOR and sends an alarm
signal to the automatic control panel when it detects an
abnormal discharge.
6.3.2 Operating principle (Alarm function)
The Discharge Detect relies on the rotation speed
change of the horizontal shaft to do the action; when the
rotation speed falls to a preset level due to sudden loss
of energy by sludge discharge, the Discharge Detector
detects it by means of a proximity switch installed on the
horizontal shaft to determine that sludge discharge has
taken place.
Also, the Multi-Monitor tells that the purifier is in
operation for safety and precaution through the rotation
display LED (green).
In addition, as a self-diagnosis function, the trouble
display LED (red), also on top of the Multi-Monitor, is lit
to indicate a troubled purifier when the detector output is
equivalent to 2500 rpm or more or when rotation pulses
skip.
6.3.3 Connecting with control panel
To prevent a false alarm, the Multi-Monitor is fed with "discharging" signal from the automatic control panel
during sludge discharge and issues an alarm signal only during feeding.

(The proximity switch may be out of position.)
Correct its position. This LED goes out as soon as its input signal has been stabilized.
NOTE
The trouble display LED (red) may be transiently illuminated when the purifier is in or out of
operation, which is no indication of the detector being in trouble.
3. "No-Discharge display"(red)
In the state of a "discharging" signal being fed from the automatic control panel, if there is not a predetermined
amount of speed drop in the oil purifier, the Error LED (red) on the Multi-Monitor panel and "No -Discharge"
signal output LED (red) above the boards in the Multi-Monitor are illuminated. At the same time, an alarm is
delivered to the Multi-Monitor and the oil purifier is stopped as a result.

6.4 Water Detector Function (WD)
6.4.1 General
The Water Detector Function (WD) of the Multi-Monitor is a device to prevent separated water from leaking
into light liquid (purified oil). It is available in two types, i.e., pressure sensor type water detector (GSH-1) and
electrostatic capacity type water detector (option).
6.4.2 Pressure sensor type water detector (GSH-1/MM-3)
6.4.2.1 Operating principle
The Water Detection system provided with a pressure sensor, which is called G-HIDENS system, is controlled
on the automatic control panel (GSH-1) via the Multi-Monitor (MM-3).
The G-HIDENS system constantly monitors separated water being accumulated in the bowl by means of a
pressure sensor installed in the circulation line and causes separated water to be discharged before it leaks
into light liquid (purified oil).
In the clarifier operation, some of light liquid (purified oil) is returned to the feed liquid inlet via circulation line.
The circulation line, which is provided with a back pressure valve, pressure sensor and pressure gauge, is
maintained under a required level of back pressure by means of the back pressure valve, with the shut-off
valve in the heavy liquid outlet line fully closed.
Upon arrival of separated water in the bowl at the top disc outside level, the circulation of light liquid is stopped
with an instantaneous drop in circulation line pressure. Detecting this pressure change, the pressure sensor
sends a signal to the control panel via the Multi-Monitor to tell that the predetermined quantity of separated
water has been accumulated in the bowl and separated water is discharged, normally in the partial discharge
mode. In some cases, total charge with sludge takes place, depending on time spent before detection of
pressure drop.

6.4.2.3 LED displays
"Water detection display"(red)
In the state of being fed with "feeding" signal from the automatic control panel, when the pressure sensor in
the G-HIDENS system circulation line detects the arrival of separated water at the predetermine level in the
bowl, the Error LED (red) on the Multi-Monitor panel and the confirmation LED for output signal "Water
Detection" LED (red) above internal boards in the Multi-Monitor are illuminated. At the same time, a signal is
delivered to the control panel and the oil purifier is stopped after sludge discharge.
Also, for self-diagnosis, when an extraordinarily high voltage (equivalent to 0.45MPa {4.5 kgf/cm2}) is detected
at the pressure sensor, the "Water Sensor Abnormal" output LED (red) in the Multi-Monitor is illuminated, with
"Error" and the corresponding error identification number indicated in the upper and lower seven segment
displays, respectively. At the same time, an alarm is issued to the control panel and the oil purifier is stopped
as a result after sludge discharge.
NOTE
To prevent a false alarm due to pressure fluctuation or pulsation at the start of oil feed or during
normal running, the Delay Timer and Hold Timer are provided. Either timer is actuated when
pressure falls below the preset level during running. If pressure fails to return to normal after the
timer is up, the detector recognizes it as a "Water Detected" status and sends an alarm signal to the
control panel.
NOTE
When the self-diagnosis function is actuated, the Multi-Monitor holds "Error" and the error
identification number in display, which cannot be cleared until power is turned off. After the cause
is identified and eliminated, reset by turning power off, then on.

6.4.2.4 Routine running
For clarifier operation that needs the Water Detector Function, select "Water Detector Function" on the Water
Detector Function selector dial in the Multi-Monitor. (See Fig. 6-19) For purifier operation that needs no Water
Detector Function, select "No Water / Heavy liquid Detector Function" on the same dial.
With the Water Detection output switch (See Fig. 6-19) in the ON position, the Water Detector monitors
water being accumulated in the bowl. When it detects the arrival of water at predetermined level, it sends
an output signal to the control panel and causing water to be discharged.
Normally, clarifier operation is performed with the Water Detection output switch placed in the ON
position.
NOTE
When clarifier operation is switched to the purifier operation, the Water Detector Function selector
dial in the Multi-Monitor setting must be from " Water Detector Function " to " No Water / Heavy
liquid Detector Function " but the position of the Water Detection output switch needs not be
changed to OFF.

6.4.3 Electrostatic capacity type water detector (GSH-1/MM-2)
The electrostatic capacity type water detector relies on difference in dielectric constant between water and oil
to determine the capacitance of oil, thereby detecting the water content of oil.
This detector is installed in the light liquid outlet piping of the SELFJECTOR and controlled on the automatic
control panel (GSH-1).
In the clarifier operation, the detector monitors the water content of light liquid. When a rise of approximately
0.5% occurs in the water content, the detector recognizes it as "water in the bowl having arrived at
predetermined level" and issues an output signal to the control panel. Water is discharged as a result.
6.4.3.1 Connecting with control panel
To prevent a false alarm, the electrostatic capacity type Water Detector is fed with "feeding" signal from the
automatic control panel and issues an alarm signal only during feeding. This detector exchanges signals with
the control panel, not via the Multi-Monitor but directly.

6.5 Partial discharge detection function (GSH-1)
The automatic GSH-1 system combined with Multi-Monitor MM-3 has a Partial Discharge Detection Function
that, in addition to sludge discharge monitoring, indicates whether or not sludge discharge is optimal for partial
discharge adjustment.
6.5.1 Operating principle
When the Partial Discharge Detection Function of the Multi-Monitor monitoring the horizontal shaft rotation
speed of the SELFJECTOR detects a rotation speed drop (peak hold) during sludge discharge, it compares
the data with the optimal discharge value preset for each SJ-G model to determine if the quantity of discharge
effected is optimal. And the Multi-monitor indicates the result of comparison through confirmation LEDs
(Over, Just, Under) for partial discharge. (See Fig. 6-22)

1.3 Safety precautions
! WARNING
The bowl of SELFJECTOR produces a large centrifugal force when it rotates. Wrong handling is very
dangerous. Pay utmost attention according to the manual for operation, disassembly, reassembly,
maintenance, checkup, etc. Use of non-genuine parts might damage SELFJECTOR or impair human
safety. Be sure to employ genuine parts.
Perfectly assemble.
Many points of SELFJECTOR are connected by screws. When assembling, make sure tightening is
complete. Running with poor tightening is very dangerous. Doubly make sure of secure tightening
particularly of:
(A) Bowl nut
(B) Disk nut
(C) Cap nut of Vertical shaft
(D) Set bolt of Frame cover
(E) Lock nut (hexagon) of Inlet pipe
Be sure that tally marks of the bowl and other so marked parts are aligned.
If the tally mark is excessively mis-aligned when the Bowl nut is tightened, contact our company or
service agency.
Immediately stop if vibration is excessive.
Vibration of SELFJECTOR is caused by unbalance, ship oscillation,
SELFJECTOR installation, etc. If the vibration is excessive, immediately
stop SELFJECTOR without discharging sludge.
Then, check for the cause and take necessary corrective action to ensure
safety before restarting SELFJECTOR.
To be more specific, if the vibration at the point A of Fig. 1-1 exceeds
100 μm (peak to peak) at rated speed, stop SELFJECTOR.
Even if readings are below 100 μm, continuous cruising ship vibrations
4-5 times higher than registered when external vibrating forces are small,
such as when the main engine is not in operation, could adversely affect
the durability of SELFJECTOR. In such case, stop SELFJECTOR
immediately. Then, check for the cause and take necessary corrective
action to ensure safety before restarting SELFJECTOR as described
above.

SELFJECTOR Instruction Manual Operation Manual2 2-3
2.2.1 Display Function
Data necessary for daily monitoring of operational status are digitally indicated through seven
segment LEDs.
Indicated data pertain to flow rate, temperature, pressure, rotation number, circulation line pressure
(G-HIDENS spec.), though those vary with different models of the Multi-Monitor.
NOTE
Since the flow rate displayed on Multi-Monitor(MM) is the value which converted pressure into
flow rate , please use it as a guideline.
When you always use a gear pump under 30% or less of its rated capacity, we recommend using
the small orifice (option) under 1 rank.
2.2.2 Leakage Monitor Function (LM)
The Leakage Monitor is a protective device that detects the treated oil leaking from the sludge
outlet or heavy liquid outlet of the SELFJECTOR by means of a pressure sensor, thereby
minimizing the loss of treated oil.
The pressure sensor is installed on the SELFJECTOR bracket (at the light liquid outlet) and
constantly monitors pressure during feeding. When a pressure drop occurs due to a leakage, the
pressure sensor detects it and the pressure sensor output is sent as a "Leakage" signal to the
automatic control panel via the Multi-Monitor.
2.2.3 Discharge Detector (DD)
The Discharge Detector is a protective device that monitors sludge discharge from the
SELFJECTOR and detects a discharge failure as the "No-discharge" status.
Normal sludge discharge is accompanied by a drop in horizontal shaft rotation speed to the preset
level. Relying on this characteristic, the Discharge Detector constantly monitors the horizontal shaft
rotation speed by means of a proximity sensor. If the horizontal shaft rotation speed fails to fall at
sludge discharge, a "No-discharge" signal is delivered to the automatic control panel via the
Multi-Monitor.
As a self-diagnosis function, "No-discharge" LED (red) is illuminated in response to a shaft rotation
number beyond 2500 rpm or an instable proximity switch input signal.
In addition to the sludge discharge monitoring function, the automatic GSH-1 system combined
with Multi-Monitor MM-3 has a partial discharge detection function to indicate whether or not sludge
discharge is optimal for partial discharge adjustment.
2.2.4 Water Detector Function (WD)
The Water Detector is an integral device that is used for the G-HIDENS system (for clarifier
operation) that constantly monitors the changing levels of separated water in the bowl by means of
a pressure sensor installed in the circulation line.
Pressure in the circulation line falls when separated water in the bowl has reached a predetermined
level. The Water Detector in the G-HIDENS system detects this pressure change by means of the
pressure sensor and effects partial discharge or total discharge with sludge, whereby the inside of
the bowl is always maintained in a normal separating condition.
The Water Detector is used only in the automatic GSH-1 system configuration.

SELFJECTOR Instruction Manual Operation Manual2 3-2
3.2 Treating Temperature
The treating capacity of the oil purifier depends mainly on the viscosity of feed liquid. To ensure that the
oil purifier operates efficiently, heat the feed liquid to specified temperatures of Table 3-2 as
appropriate.
Table 3-2
Oil type Treating temperature(℃)
A heavy oil 14 mm2/sec at 40℃ 40
C heavy oil 180~700 mm2/sec at 50℃ 98
100 mm2/sec at 40℃ (SAE#30) 74~90
Lubricating oil 150 mm
2/sec at 40℃ (SAE#40) 83~95
Fig. 3-1 shows the relationship between various oil temperatures and their viscosity.
How to obtain a treating temperature
【Ex.】Case of purifying a heavy oil of 45 mm2/sec (50℃)
Draw a dotted line that is parallel to the line of 40 mm2/sec at 50℃ and passes an intersection (point A)
between a horizontal line of 45 mm2/sec and a vertical line of 50℃. From the intersection between this
line and a horizontal line of 24 mm2/sec draw a line perpendicular to the horizontal axis, then read the
temperature falling on the foot; that is 67℃.
Thus the treating temperature of this heavy oil should be 67℃.

SELFJECTOR Instruction Manual Operation Manual2 3-4
3.3 Gravity Disc
In the purifier operation it is necessary to hold the interface between the light liquid and heavy liquid in
the bowl within a definite rage. Therefore, the SELFJECTOR can employ gravity discs of various inside
diameters such that the outlet diameter of the heavy liquid side can be altered for interface position
adjustment. One gravity disc having a larger inside diameter, if incorporated, moves the interface
outward, and another disc having a smaller inside diameter moves the interface inward.
Selection of an appropriate gravity disc is one of the most important subjects for oil treatment with the
SELFJECTOR. Exercise sufficient care for this selection to avoid unintended purifier operation.
NOTE
At the delivery of a SELFJECTOR, the gravity disc and bowl come in each package.
Select an appropriate gravity disc and assemble it in the bowl according to Section 3.3.2
"Gravity Disc Selection Procedure".
3.3.1 Supplied gravity discs
! CAUTION
Before treating a different type and nature of oil, select a suitable gravity disc having an
inside diameter that fits the gravity of the treated oil.
Running the purifier with a gravity disc of incorrect diameter may cause oil outflow to the
heavy liquid side and water circulation over the light liquid side.
Table 3-3 shows the supplied standard gravity discs for the purifier operation and Table 3-4 shows the
gravity discs for the G-HIDENS operation.
NOTE
Actually supplied gravity discs differ for types of the treated oil. For detail refer to the attached
document and drawing.

3.4 Lubrication Oil
Lubrication oil in the gear case lubricates each
bearing of the vertical and horizontal shafts as well
as the acceleration gear.
The available lubrication method includes the oil
bath and splash lubrication by a spiral gear.
As the maintenance performance of the lubrication
oil seriously affects the life of each power
transmission unit, sufficient care should be
exercised on its handling.
For this lubrication, remove the gear cover or
lubrication plug attached on the gear cover.
! CAUTION
Before supplying the lubrication oil, be sure to stop the SELFJECTOR. The oil becomes very hot
during operation. To avoid the risk of the oil being scattered around to burn operator's hand or
hurt his eyes, do not remove the plug or gear cover when the SELFJECTOR is in operation.
3.4.1 Oil quantity
! CAUTION
Oil quantity should be checked with the SELFJECTOR being held
horizontally.
Refilling the lubrication oil as to exceed the upper red line (H) may
cause additives contained in the lubrication oil to deposit into sludge,
which can adversely affect the lubrication effect. Take sufficient care
not to exceed the upper red line (H).
Refer to
Table 3-6 for appropriate oil quantities. Refill the oil up until the red
line (H) on the oil gauge as shown in Fig. 3-31.
During operation make sure that the oil level falls in-between the red lines (H) and (L).

3.5 Sludge Discharge Interval
! CAUTION
Too long sludge discharge intervals may cause defective separation and mechanical damage on
the unit.
The optimum sludge discharge interval varies with the operation method and nature of the treated oil,
etc., which makes it hard to be uniformly determined.
Too long intervals may accelerate the contamination inside the bowl and result in sludge deposition,
whilst too short intervals may reduce the operation efficiency.
NOTE
To determine an optimal discharge interval, it is a recommended practice to perform a test run
under practical conditions for a certain length of time and find an interval commensurate to
sludge concentration in the treated oil while watching the internal state of the bowl partial
accumulation of sludge, contamination of disc(1), etc.
3.5.1 Discharge Interval (Total discharge)
The general discharge intervals and amount of sludge discharge for the treatment of fuel and lubricating
oils by the manual type GAP-11 and automatic types GBC-1, GBC-2, and GSH-1 are as shown in Table
3-8 and Table 3-9, respectively.

3.5.2 Discharge Interval (HIDENS specification)
For reference, Table 3-10 shows the general discharge intervals where a fuel oil or lubricating oil is
treated in automatic specification GSH-1.
The automatic specification GSH-1 discharges sludge in the total discharge and separated water in the
partial discharge. In some cases, however, total discharge of separated water with sludge takes place,
depending on the amount of time spent for water detection. The lubricating oil treatment can include
post-total discharge the bowl washing process at a certain rate. The sludge discharge rates for different
types are generally as shown in Table 3-9, though they vary with the frequency of water detection.

Operate the lubricating oil purifier continuously as long as possible.
Should the purifier be forced to stop for the reasons below, operate it for approximately 12
hours with sludge discharged at 10 to 20 minutes intervals before setting for discharge at
standard intervals after taking into consideration of the system oil at the time of normal
operation.
Restarting the engine and purifier after stopping
them in the anchorage or dock.(This is because
the sludge density increases at the inside

3.6.1 Operating water quality
! CAUTION
When hard water is used, scale will be produced on the inside surface of the water
supplying device, drain nozzle, or solenoid valve, which may cause various troubles.
The harder the water, the more scales on the water supplying device and pilot valve. To
prevent it, the cleaning intervals should be as short as practically possible.
Since the operating water is used for the opening/closing valve of the purifier bowl, its quality should be
pure, transparent and soft water such that it can prevent the valve from scaling or corrosion.
Use that quality of operating water, as follows:
Evaporation remainder 10 mg/L or less
Total hardness 110 mg/L or less : as CaCO3 /L (Hardness 6°dH or less)
pH value 6.5 to 7.5
Salt content 100 mg/L or less: (Cl- 60 mg/L or less)
3.6.2 Setting pressure of operating water
Use the following operation water pressure for each of automatic specifications.
Automatic type Discharge type Set pressure

SELFJECTOR Instruction Manual Operation Manual2 3-44
To adjust the operating water pressure, use the adjust screw on top of the reducing valve while reading
the valve's pressure gauge. (See Fig. 3-17)
How to pressure adjustment with adjust screw
Turn clockwise: Pressure increases.
Turn counter-clockwise: Pressure decreases.
The reducing valve has been shop-adjusted for optimal water pressure according to manual and
automatic specifications shown in Section 3.6.2.
! CAUTION
When setting or adjusting the operating water pressure during running, use the manual handle
of SV2 while running operating water for bowl closing. When the purifier is not running, perform
this with the operating water inlet tube (Teflon) removed. Otherwise, the operating water could
find its way to the gear case to damage bearings.
NOTE
The pressure of the operating water reducing valve may increase after the SV2 solenoid valve
closes, but this is not an anomaly.

3.6.3 Operating water for opening bowl
The operating water for opening bowl is used to force down the main cylinder to open the bowl, letting
out sludge and water accumulated in the bowl in the "total discharge" or "partial discharge".
In the case of total discharge, the operating water is regulated by the solenoid valve SV1 and
introduced into the bowl opening water pressure chamber via feeding device.
In the case of partial discharge (GSH-1 specification models only), the operating water is regulated
by the solenoid valve SV9 and introduced into the bowl closing water pressure chamber via feeding
device. When the bowl closing water pressure chamber has been filled up, the bowl opening water
overflows into the bowl opening water pressure chamber, depressing the main cylinder to open the
bowl instantly.
3.6.4 Operating water for closing bowl
The operating water for closing bowl is used to force up the main cylinder to close the bowl. The bowl
closing water is regulated by the solenoid valve SV2 and introduced into the bowl closing water
pressure chamber via feeding device. The bowl closing water is introduced intermittently into the bowl
closing water pressure chamber for a predetermined period of time during purifier operation.
! CAUTION
Where the primary pressure of operating water is lower than 0.2 MPa (2.0 kgf/cm2), the bowl
closing failure could occur.

3.6.5 Quantity of sealing water/regulating water and replacement water, washing water
! CAUTION
If the sealing water and replacement water are not adequate in quantity;
Oil loss during sludge discharge will increase,
Water circulates over the light liquid side, or
Oil flows out from the heavy liquid side.
Therefore, be sure to set correct quantities of these waters.
Sealing water is used to form a water phase within the bowl prior to performing a purifier-run and prevent feed liquid from flowing out of the heavy liquid side when it is supplied. On the other hand, replacement water is used to collect oils in the bowl before discharging sludge so that the oil loss can be minimized. The quantities of sealing water and replacement water required by different models shown below, respectively.

3.7 Partial Discharge Setting/Adjustment (GSH-1)
Partial discharge (amount of sludge) adjustment can be accomplished through pressure control by the
reducing valve for operating water. The Multi-Monitor (MM-3) tells whether or not partial discharge is
optimal.
3.7.1 Setting/adjustment of partial discharge
1. Set the timer (T011) of the control panel to 0.6 sec.
2. Set the reducing valve connected to the solenoid valve unit for secondary pressure at a standard
preset level of 0.25 MPa (2.5 kgf/cm2).
NOTE
The primary pressure of the supply water line should be 0.35 to 0.5 MPa (3.5 to 5.0 kgf/cm2).
The supply water pressure beyond 0.75 MPa (7.5 kgf/cm2) could cause a reducing valve
failure.
To adjust the reducing valve for optimum secondary pressure, use the adjust screw that is exposed if
the seal on top of the valve is removed. Turning the adjust screw as required, set the reducing valve for
desired pressure while reading its pressure gauge. Turning the adjust screw clockwise increases the
secondary pressure and a counter-clockwise turn decreases it.
Proper pressure setting on the reducing valve provides the discharge rates of Table 3-11 “Separated
Water Discharge Rates (Partial Discharge)”. After pressure setting/adjustment, check through the
Multi-Monitor that sludge discharge is optimal in accordance with Section 3.7.2 “Monitoring Partial
Discharge”.

SELFJECTOR Instruction Manual Operation Manual2 3-49
NOTE
With the reducing valve for operating water set (shop-adjusted) for secondary pressure
at a standard preset level of 0.25 MPa (2.5 kgf/cm2), be sure to ascertain that partial
discharge is optimal by measuring its quantity.
Increasing the reducing valve secondary pressure increases sludge discharge. To
decrease, lower the pressure.
The pressure of the operating water reducing valve may increase after the SV2 solenoid
valve closes, but this is not an anomaly.
3.7.2 Measure of the amount of partial discharge
The measure of the partial discharge is available only in the automatic control (GSH-1) system.
To measure, there are two methods:
1. Continuous measurement during normal operation.
2. One-time measurement for discharge adjustment or check
In this paragraph, the procedure for one-time measurement will be described. Before measure of the
partial discharge, make sure that the sensor is in position by reference to Section 4.3.3 “Checking
Proximity Switch Position” in this manual.
! CAUTION
Described below is the general procedure for checking the amount of partial discharge. Prior to
starting operation, be sure to refer to Section 5. “Operation“ in this manual. Given instructions
are subject to the SELFJECTOR being ready to start. (The piping had completed for operation).
1. Set the power switches of the starter, automatic control panel and Multi-Monitor to ON in that order.
2. Remove the front cover of the Multi-Monitor and check that all internal switches are in the
designated positions.
1) Check that the 50Hz/60Hz selector switch is in the position of power frequency for the
SELFJECTOR. (See Fig. 3-36)
2) Set the DD alarm output switch to OFF. (See Fig. 3-36)
3) Set the Partial ON/OFF switch to OFF. (See Fig. 3-36)
NOTE
Each model of the SELFJECTOR has a different range of optical discharge.
Correct measurement cannot be performed without proper settings. (Refer to Section 4.1.2)
3. Start the SELFJECTOR in accordance to the start-up procedure described in Section 5.
“Operation”.
4. Ascertain that the SELFJECTOR has entered into purifier operation. Purifier operation is started in
response command signals received by the Multi-Monitor from the automatic control panel, when
the confirmation LED for input signal "Feeding"(green) in the Multi-Monitor and the “Rotation
Display LED”(green) on the Multi-Monitor are illuminated.
5. Press the Discharge measurement switch in the Multi-Monitor. The green "Measuring" LED of the
confirmation LED for partial discharge quantity is illuminated. This indication means that the purifier
is ready for measurement. (See Fig. 3-36)

6. Then, press the “DISCHG.TEST” push button on the automatic control panel.
7. The sequence of the automatic control panel proceeds to the "sludge discharge" process and
sludge discharge takes place.
8. The revolution sensor (proximity switch) installed in the purifier picks a drop in horizontal shaft
speed and its output signal equivalent to the quantity of sludge discharge effected is sent to the
Multi-Monitor.
9. The input is indicated through appropriate Partial Discharge LED in the Multi-Monitor; red LED for
"OVER", green LED for "JUST" or red LED for "UNDER". (See Fig. 3-36)
10. If "OVER" LED (red) or "UNDER" LED (red) is illuminated, regulate the secondary pressure of the
reducing valve for operating water (refer to Section 3.7.1 and perform above operations from Step 5
downward to adjust the quantity of discharge until the "JUST" LED (green) is illuminated.
NOTE
A change in reducing valve setting must be followed by discharge tests to have line pressure
stabilized before proceeding to discharge measurement.

4.1.2 Accessing Memory Preset Items and Changing Memory Settings
4.1.2.1 Accessing Multi-Monitor Memory Preset Items
To access the memory preset items of the Multi-Monitor, use the function setting switches (SW1 to 4).
Press the function setting switch 4 (SW4: Enter) for 2 seconds and release. A preset item number
appears in the upper seven-segment display with the current preset value indicated in the lower. Keep
pressing the function setting switch 1 (SW1: Select) until the desired preset item number is displayed.
4.1.2.2 Changing Multi-Monitor Memory Preset Value
When it becomes necessary to change a memory preset value, access the number of the item to be
changed through the function setting switch 1 (SW1: Select) and change it by means of the function
setting switch 2 (SW2: Forward) or the function setting switch 3 (SW3: Backward). The preset value
increases or decreases at minimum variable steps predetermined for each preset item. Key in a desired
new value and press the function setting switch 4 (SW4: Enter). The new value is registered in the
memory.
NOTE
Preset values cannot be changed without pressing the function setting switch 4 (SW4).
4.1.2.3 Locking Display
During normal operation, "flow rate" is always indicated in the upper seven-segment LED display, and
"feed liquid temperature"/"light liquid pressure" appears in the lower changing (incrementally) at steps of
5 seconds.
At the start of operation or during operation, when back pressure at the light liquid outlet becomes
necessary to adjust to optimize the Leakage Monitor function of the Multi-Monitor or for other reason,
press the Pressure Display Lock switch on the Multi-Monitor panel once. This freezes the "light liquid

4.2.3 Light Liquid Outlet Pressure Adjustment
To ensure proper functioning of the Leakage Monitor, the
adjustment of light liquid outlet pressure to the light liquid
pressure level preset in the Multi-Monitor (memory preset
item No. 13) through back pressure control valve is required.
Carry out this adjustment as follows.
1. Accomplish pre-operational checks. (Refer to Section
5.1.4 “Inspections Prior to Running”.)
2. Switch on the starter, automatic control panel (or alarm
panel) and Multi-Monitor in that order.
3. Set the MM function switch on the automatic control
panel (or alarm panel, starter panel) to ON and the LM
alarm output switch in Multi-Monitor to OFF.
4. Remove the front cover of the Multi-Monitor and check
that all internal switches are in the appropriate positions.
5. Start the oil purifier in accordance with the starting
procedure. Do not start feeding until the rated speed has
been reached.
6. While watching the flow rate display on the Multi-Monitor,
adjust the bypass valve and flow rate control valve for
the feed rate specified for the SELFJECTOR being operated. At the same time, fully open the back
pressure control valve (needle valve) at the light liquid outlet and record the pressure at that point
without fail.
7. Check that the feed liquid temperature is at the preset level through the feed liquid temperature
display on the Multi-Monitor. If lower, pressure drops when the feed liquid reaches the preset
temperature and an alarm is issued in some cases.
8. Press the pressure display lock switch on the panel (or the function setting switch SW1 in the
Multi-Monitor) to freeze the indications of flow rate and light liquid pressure in the upper and lower
seven-segment displays. While reading the light liquid pressure on the Multi-Monitor, accomplish
pressure adjustment to the level preset in the Multi-Monitor (refer to Section 4.2.2) through the
pressure control valve at the light liquid outlet.
9. Make fine adjustment of pressure through the back pressure control valve until the pressure control
LED (yellow) on top of the Multi-Monitor is illuminated. This LED flashes when pressure is within ±
15% of the level preset in the Multi-Monitor and is illuminated within ± 3%.
10. After the adjustment of light liquid outlet pressure is completed, press the pressure display lock
switch on the panel (or the function setting switch SW1 in the Multi-Monitor) again to release the
pressure display locked status. Set the MM function switch on the automatic control panel to OFF
and then to ON. After that, the LM alarm output switch in Multi-Monitor to ON. Finally, reinstall the
front cover of the Multi-Monitor.
NOTE
For a period of approximately 20 to 30 seconds after the MM function switch on the automatic
control panel (or the alarm panel or starter) is set to ON from OFF, the LED displays of the
Multi-Monitor remain blank, which is a normal transient phenomenon.
In addition the manual SELFJECTOR version with no alarm panel has the MM function switch
installed on the starter.

SELFJECTOR Instruction Manual Operation Manual2 4-10
! CAUTION
1. The level of "light liquid pressure" preset in the Multi-Monitor is the "measured pressure
recorded in 6" plus LM trigger pressure ΔP (standard value: 0.02 MPa).
Be sure not to set it beyond 0.2 MPa (2.0 kgf/cm2). Setting beyond 0.2 MPa (2.0 kgf/cm2) may
cause the light liquid to overflow the light liquid chamber. (Refer to Section 4.2.2.)
Standard value for setting "light liquid pressure" is 0.15 MPa (1.5 kgf/cm2) for fuel oil, and is
0.10 MPa (1.0 kgf/cm2) for lubricating oil.
2. The level of "minimum light liquid pressure" preset in the Multi-Monitor should be less than
the "light liquid pressure" mentioned above minus LM trigger pressure ΔP.
This value must be higher than the "measured pressure recorded in 6." If it is equal to or lower
than the recorded level, the Leakage Monitor may fail to detect a leakage of treated oil properly.
Standard value for setting "minimum light liquid pressure" is as follows,
[Minimum light liquid pressure]
= [Light liquid pressure] – [LM trigger pressure ΔP] – [0.01 to 0.02] (MPa)
NOTE
Normally, once adjusted at trial run, light liquid outlet pressure requires no further
adjustment unless there are fluctuations in flow rate and temperature.
During daily check, ascertain proper illumination of the pressure control LED (yellow) and
correct indication in the light liquid pressure on the Multi-Monitor.
LM trigger pressure follows up pressure fluctuations due to pulsations during operation.
Even if the pressure control LED (yellow) flashes, therefore, there is no particular need for
pressure adjustment.
4.2.4 Checking Timer Setting after Start of Feeding Always check that the following timer setting is correct after oil feed is started. Delay timer
Ascertain that the time from the start of feeding after sludge discharge to the arrival of discharge side pressure at preset level is shorter than the time preset on the delay timer.
NOTE1
Control fluctuations in the flow rate of feed liquid to the purifier to be within ± 0.01 MPa in
pressure equivalent.
NOTE2
Control feed liquid temperatures to be within ± 5% of preset level. Excessive fluctuations
change the feed liquid in viscosity to fluctuate light liquid outlet pressure as a result, possibly
affecting the output of the Leakage Monitor Function of the Multi-Monitor.
4.2.5 Pressure Adjustment after Feeding 1. Set the LM alarm output switch in Multi-Monitor to OFF. 2. Accomplish the steps 8 to 10 in Section 4.2.3 “Light Liquid Outlet Pressure Adjustment”.

Discharge Detector Function (DD)
NOTE
The Discharge Detector Function (DD) of the Multi-Monitor is a protective device that relies on a
shaft speed drop to work. More specifically, if the horizontal shaft speed is not dropped during
sludge discharge, the detector detects it as a "No-Discharge" status by means of a proximity
switch. If the proximity switch is out of position or the switches are set wrong, a false alarm is
issued.
4.2.6 Setting Up the Discharge Detector Function
For the Discharge Detector Function, the Multi-Monitor is provided with a Partial ON/OFF switch for
monitoring sludge discharge among others, in addition to normal and abnormal speed indicating means.

If the oil purifier will not be used for a long period of time (more than 3 months) carry out the following
inspection, maintenance and service activities.
6.1 Preparations for Suspension
1. The frame and sludge cover should be disassembled for cleaning. After completely removing
moisture, apply rust-preventive oil all over the inside surface.
2. After disassembling and cleaning, the bowl should be applied lubricating oil, then re-assembled.
Apply rust-preventive oil on the outside surface of the bowl, and store it separately without
re-assembling in the vertical shaft.
3. The vertical and horizontal shafts should be disassembled for cleaning. After cleaning, apply
rust-preventive oil all over the surface, then re-assemble them in the purifier main body.
4. The inside surface of the gear case should be applied rust-preventive oil after cleaning. Do not refill
lubricating oil before starting operation.
5. After disassembling and cleaning, the gear pump should be applied lubricating oil, then
re-assembled. Accumulated oil, if present in the pump connecting tube, should be completely
removed in advance so that it from does not flow into the gear pump.
6. Close the source valve of the operating water pipe, then drain water from the pipe and open the
flange.
7. Place appropriate desiccant in the Multi-Monitor.
! CAUTION
Place appropriate desiccant in the starter, control panel and Multi-Monitor and wrap them
closely in vinyl film sheet or the like. Condensation due to significant moisture may cause
rust inside. Close the butterfly valve at the sludge outlet.
Shut the butterfly valve. If the butterfly valve is open during suspension, vapors from the
sludge tank may cause the shaft system to be oxidized.

After setting the power switch of the control
panel to "OFF", replace the power fuse with a
spare one.
In this case, set the power switch on the
control panel to "OFF" and then to "ON"
again. If the same conditions persist, no
automatic operation is possible. A defective
control unit or DC power supply is suspected.
Temporarily bridge external
terminals, "M11" and "M12", to
check whether the LED "MTR" of
the terminal unit lights.
Check the external wiring
between the starter and
automatic control panel.
A defective control unit is
suspected. Check the starter
Set the power switch of the
control panel to "ON".

2.OVERVIEW OF AUTOMATIC CONTROL PANEL
The control panel is used for automatic purification of the feed oil by the Mitsubishi SELFJECTOR. It is so
designed that, if a trouble like an abnormal oil leakage or sludge discharge failure (failure to open the bowl)
occurs during operation, the supply of the feed oil and then the SELFJECTOR may be stopped
automatically.
<Automatic Operation Process>
Closes the main cylinder of the bowl → Supplies sealing water → Supplies feed oil (purifier operation) →
Supplies replacement water → Opens the main cylinder of the bowl (discharges sludge).
The control panel outputs “Feeding” signal to the Multi-Monitor (MM), and has separated water discharged
in response to “alarm (water detection)” signal from the Multi-Monitor. If the number of times water
discharge is detected is abnormally large, the control panel automatically shuts down the SELFJECTOR
after completion of the discharge process. For detailed information on the Water Detector Function (WD)
of the Multi-Monitor, refer to “OPERATION MANUAL 2”.
The control panel has a built-in programmable controller to control the automatic operation processes.
The control panel consists of the following devices.
Programmable controller
(1) CPU board: PZ3M
(2) Operation display panel: S-10D-M
(3) Expansion board: PZ3ME (Option)
Control switches, pilot lamps, fuses, relay board and terminal board

10.3."03": ABNORMAL WATER CONTENT ALARM
This alarm occurs when the water detection count is abnormally high.
When the Multi-Monitor detects the water content in the bowl, its water detection signal is input to
the CPU board and a water discharge operation is effected, when the water detection setting
counter (C027) adds one time to the current count. C027 is reset every time the water detection
count reset timer (C026), which is repetitively actuated during automatic operation, expires. If the
water content of the feed oil is abnormally high, water detection is repeated within a short period of
time, C027 counts up to give an abnormal water content alarm signal. When this signal is issued,
the SELFJECTOR is automatically stopped after discharging sludge.

1.3 Safety precautions
! WARNING
The bowl of SELFJECTOR produces a large centrifugal force when it rotates. Wrong handling is very
dangerous. Pay utmost attention according to the manual for operation, disassembly, reassembly,
maintenance, checkup, etc. Use of non-genuine parts might damage SELFJECTOR or impair human
safety. Be sure to employ genuine parts.
Perfectly assemble.
Many points of SELFJECTOR are connected by screws. When assembling, make sure tightening is
complete. Running with poor tightening is very dangerous. Doubly make sure of secure tightening
particularly of:
(A) Bowl nut
(B) Disk nut
(C) Cap nut of Vertical shaft
(D) Set bolt of Frame cover
(E) Lock nut (hexagon) of Inlet pipe
Be sure that tally marks of the bowl and other so marked parts are aligned.
If the tally mark is excessively mis-aligned when the Bowl nut is tightened, contact our company or
service agency.

SELFJECTOR Instruction Manual Maintenance Manual 1-4
Immediately stop if vibration is excessive.
Vibration of SELFJECTOR is caused by unbalance, ship oscillation,
SELFJECTOR installation, etc. If the vibration is excessive,
immediately stop SELFJECTOR without discharging sludge.
Then, check for the cause and take necessary corrective action to
ensure safety before restarting SELFJECTOR.
To be more specific, if the vibration at the point A of Fig. 1-1 exceeds
100 μm (peak to peak) at rated speed, stop SELFJECTOR.
Even if readings are below 100 μ m, continuous cruising ship
vibrations 4-5 times higher than registered when external vibrating
forces are small, such as when the main engine is not in operation,
could adversely affect the durability of SELFJECTOR. In such case,
stop SELFJECTOR immediately. Then, check for the cause and take
necessary corrective action to ensure safety before restarting
SELFJECTOR as described above.

2.1.2.4 Removing main cylinder
! CAUTION
Use care to prevent damage to the sheet surface and
sliding portions.
NOTE
To remove the main cylinder, mount the jack (1) and
then strike the jack evenly all around with a
protective rod or something else in between to lower
the main cylinder all the way. Then draw up the main
cylinder by use of the tool.
Spray a penetrating lubricant against the inside and
outside circumferential sliding portions of the main
cylinder beforehand. An effective auxiliary means is
to put cubes of ice inside the main cylinder
( indicated by the arrow ) and remove them 2 or 3
minutes later.
After installing the protective plate (812) in the cap nut
installing portion of the bowl body, secure the jack (1)(803)
on the main cylinder with the socket cap screw. (Fig. 2-28)
Turn down the jack with the push bolt (819) and handle(1)
(823) to remove it. (Fig. 2-29)
NOTE
There is only a slight clearance between the main
cylinder and bowl body. When the main cylinder is
removed, if it is only slightly inclined, it can no longer be
withdrawn.
When the handle resists, do not blindly continue to rotate
the handle. Each time the handle resists, strike the top of
the push bolt with a hammer, or temporarily back it off.
By so doing, withdraw the main cylinder little by little.
(Hammering will correct the inclination of the main
cylinder and will also eliminate the eccentricity of the
tool.)

2.2.1 Bowl
(1) Make sure that when all of the O rings are mounted, they
are not twisted.
To install O ring evenly in the valve guide, apply a coat of
machine oil to it and the groove.
(2) Be sure to check the tapered portion of the bowl body. If
there are scratches, correct them by an oil stone or
something else.
(3) To install the pilot valve, apply a machine oil to its outer
circumferential portion, and slowly press the pilot valve in
by hand. If it is installed by striking with a hammer or
something else, damage to the O ring will result.
NOTE
Note that if the pilot valve is installed in a tilted state by
applying an undue pressure, its sliding surface will be
damaged.
When installing the pilot valve assembly, do not use
MOLYCOAT.
(4) Main seal ring installation procedures
① Press the main seal ring in the main seal ring groove of
the bowl hood by hand.
② The main seal ring will be placed in a state of being
lifted from the groove. Put a flat plate (50 to 100mm
wide) over across the main seal ring and evenly
hammer it down into place approximately 0.5~1.0mm
off the bottom.
! CAUTION
If the sheet plane of the main seal ring is wavy, oil leakage
will result. Install the main seal ring in such a way that the
sheet plane will be flat.
③ Before starting automatic operation, feed operating
water for closing bowl (SV2) manually for 20 seconds,
then feed operating water for opening bowl (SV1) for 2
seconds to effect discharge operation. Repeat this
operation for 3 or 4 times.
! CAUTION
It takes several tons of bowl opening water to close the
main cylinder. Repeating the cycles of water feed
described above, therefore, puts the main seal ring into
place. The main seal ring out of place could prevent sludge
from being properly discharged.

④ Put the bowl into a closed state with bowl closing
water as described in ③, and manually operate the
solenoid valve (SV3) to feed sealing water. Then, feed
bowl opening water (SV1) for 2 seconds to effect
discharge operation. At this point of time, check for the
sound of sludge discharge. (For the durations of
sealing water feed required by different models, refer
to 3.6.5 in Operation Manual 2.)
⑤ If no sound of sludge discharge is heard, the main
seal ring may be out of place. Open the bowl, check
the installed condition of main seal ring and redo the
steps from ②.
⑥ If there is the sound of sludge discharge, enter into
automatic operation.
(5) To install the main cylinder in the bowl body, apply a
lubricant to the sliding surfaces of the main cylinder. Line
up the positions of the knock pins and install the main
cylinder, while using care to make sure that it is not tilted.
(6) Make sure that the threaded portion of each of the parts
is coated with the MOLYCOAT.
(7) Make sure that all of the knock pins and keys are
completely lined up.
(8) When the disc (1) is installed, the upper discs which do
not have a fringe should be installed in the
uppermost position. Install the other disc by pressing
one at a time in the order that they were installed
whenever possible. (Fig. 2-68)
(9) The discs tend to produce some looseness because of
their seating phenomenon. In such a case, add an
appropriate number of spare discs according to Fig.
2-68 (to such an extent that the top of the distributor
protrudes 3 to 5 mm from the discs).
! WARNING
If the machine is operated with the discs in a loose state,
large vibration could occur.

(10) Bowl nut tightening procedures
(a) Securely tighten the bowl hood with the disc clamp plate
(807).(Fig. 2-69)
(b) Tighten the nut of the disc clamp plate (807) so that the
bowl nut can be turned smoothly by hand until the
distance between the tally marks of the bowl nut and
bowl body reaches 10 to 15mm. (Fig. 2-70)
(c) Tighten the bowl nut with the bowl nut handle by
use of a hammer until the tally marks are in
alignment.
(Fig. 2-71)
(11) When the bowl is to be installed in the main body of the
machine, apply a lubricant to the operating water
chamber of the water supplying device to prevent the O
ring of the operating water chamber from being caught.
Do not apply MOLYCOAT to the tapered portions of
the bowl body and vertical shaft.
(12) After the bowl has been installed in the main body,
tighten the cap nut firmly through use of the cap nut
spanner and hammer.
(13) When the light liquid chamber is to be threaded in, thread
it in by hand to prevent damage to the threaded portion.
As a final step, tighten it with the light liquid chamber
handle.
(14) When the heavy liquid chamber is installed, line up
its tally mark with the tally mark of the bowl body.
(15) Check the installed height of the bowl.

When the bearing is installed in the bearing case
If the bearing is forced in a tilted state by applying
an undue pressure, damage to the bearing might
result.
After the bearing has been installed, if the inner
race can be turned by hand, replace the vertical
shaft.
Install the bearing in the bearing case by equally striking
the inner ring with a hammer. Before installing the O ring
under the bearing housing (1), apply grease to several
places of the groove. By so doing, the O ring won't come
off and fall.
Before installing the flat spring, install a spacer on the top
of the bearing housing (1). Two types of spacers (1)
0.5mm and 1.0mm thick will be supplied. Use a spacer (1)
of appropriate thickness to adjust the dimension A of
Fig. 2-74 to the value shown in Table 2-6. Measure the
dimension A with the O ring removed from under the
bearing housing (1).

3.5 Bowl opening intervals (guidelines)
To operate the SELFJECTOR in normal condition at all times, it is necessary to open and clean
the bowl at regular intervals. Although the opening intervals vary with the properties of treatment
oil, operating condition, etc., the general opening intervals are shown below for general
guidance.
(Note 1) The rotor opening intervals which vary with the operating condition are shown for general guidance and
are not intended to guarantee the intervals.
◎ First time to open the bowl → A month after trial run
Since the inside contamination varies with the properties of oil, etc., open the bowl and check
the inside after the first month (whether unevenly deposited sludge exists or not, contaminated
discs, etc.), and determine whether the discharge intervals are appropriate or not.
◎ Second and subsequent times → Open, check and clean every 6 months (longest).
If the bowl opening intervals are too long, contamination might affect separation or even cause
vibration. Set the proper opening intervals suitable for the type of oil.
When the SELFJECTOR is used for cleaning the trunk piston engine lubricant, the bowl is
generally contaminated earlier. It is therefore advisable to set shorter intervals (2 to 3 months).
The opening intervals may be extended (longest interval is 1 year) by joint use of a
cleaning equipment. However, it is necessary to check the effectiveness of cleaning
before determining the opening intervals.
3.6 Overhaul (guidelines)
! CAUTION
When increased vibration is evident, check and maintenance the machine according to
the inspection procedures described in Section 5 even before the overhaul intervals for
the sake of safety. If there is anything wrong, replace the parts.
! CAUTION
Although the overhaul (Note 3) intervals vary with the operating condition, inspection and
maintenance according to the inspection procedures described in Section 5 at regular
intervals, overhaul the machine every 2 years (longest) at least.
(Note 2) Overhaul intervals which vary with the operating condition are shown for general guidance and are not
intended to guarantee the intervals.
(Note 3) Overhaul refers to disassembly of all of the parts of the bowl, vertical and horizontal shaft systems,
inspection and cleaning according to the inspection procedures described in Section 5, and replacement of
expendable and defective parts.

4 Maintenance inspection procedures for major parts
4.1 Bearing replacement intervals
! WARNING
For the vertical and horizontal shafts, use bearings that are up to specification. The upper
bearing of the vertical shaft in particular is important. If an out-of-specification bearing is
used, personal safety could be jeopardized because of reduced bearing life.
! CAUTION
For the sake of safety, replace the bearings of the vertical and horizontal shafts before the
elapse of 2 years regardless of whether they have been in service or not.
The bearings are expendable parts. Place separate orders for bearings other than supplied as
spare ones.
4.2 Bowl
4.2.1 Corrosion of bowl
The bowl parts except some are made of special stainless steel. Under stringent operating
condition, however, corrosion might occur in the form of pitting.
Since the bowl is exposed under a high stress, a very fine crack originating in the pitting could
occur. Be very careful when you check.
What to do to prevent corrosion
Corrosion readily occurs in the portions that are in
contact with sludge. Perform the following steps to
prevent corrosion.
(1) Set proper discharge intervals.
(2) Clean those portions when the bowl is opened.
Perform checks with special stress on the following
portions on which sludge is deposited.(Fig. 4-1)
(1) Seat portion of main cylinder.
(2) Sludge discharge port.

Check procedures
(1) Thoroughly clean to remove deposits.
(2) Visual check.
(3) If anything wrong was found under (1) and (2), perform color check test.
4.2.2 Corrective steps for corrosion
! CAUTION
To prevent distortion of the base materials and alteration of their composition, never make
repairs by welding cracks, pinholes or corroded portions.
If there is pitting in a part, remove the corroded portion by a grinder. Perform visual check and
color check test for confirmation. If there is nothing wrong, continued use of the part is allowed.
The margin removable by a grinder should be limited to 0.5mm maximum (except the main
cylinder for FO). After grinding, do buffing (#250 or more).
When there is a line defect (crack),
When more than 0.5mm grinder finishing is necessary,
it is necessary to replace the parts with new ones and perform balance adjustments.

4.2.9 Main cylinder
(1) Check the seal surface (that
surface which makes contact
with the main seal ring) for
scratches. If there are scratches,
damage to the main seal ring
and leakage of sealing water will
result, making normal operation
impossible. Scratches are often
made on the surface at the time
of disassembly. Therefore, be careful when handling it.
In the case of the main cylinder for lubrication oil, repair small scratches by use of an oil
stone or something else. In the case of the main cylinder for fuel oil (C heavy oil), contact
our company or service agency, as the seal surface has a special coating.
(2) Check the bowl body sliding surface for scratches. If there are scratches, the O ring will
wear down earlier. Repair the scratches with an emery cloth (#320) and then apply finishes
with polishing paper (#600).
(3)Clean the O ring groove. If the groove is rough, make repairs with an emery cloth.
4.2.10 Pilot valve assembly
(1) Check the valve guide and bowl body sliding
surfaces for scratches. If there are small scratches,
make repairs with an oil stone or something else.
When the pilot valve assembly is disassembled and
reassembled, use care to prevent damage to the O
ring.
(Apply a lubricant to the sliding surfaces for easier
reassembly.)
(2) Check the seal surface (that surface which makes
contact with the valve sheet) for scratches. If there
are small scratches, make repairs with an oil stone
or something else.
(3) Take out the valve sheet from the valve guide, and
clean and carefully check the seal surface.
If the valve sheet has caught a foreign substance or
is deformed (0.3mm or more), replace it with a new
one.
(4) After cleaning and before installing in the bowl,
complete the pilot valve assembly and check to
ensure that pilot valve is moved smoothly by hand.

4.3 Vertical shaft system
4.3.1 Vertical shaft
(1) Carefully check the portion above the upper bearing fitting portion, as
there is a high likelihood of corrosion. If the dimension A shown in Fig.
4-9 is more than 1mm smaller in diameter than the value shown in
Table 4-1, replace the vertical shaft with a new one.
(2) If there are partial scratches in the bowl bush fitting portion, make
repairs with set files or an emery cloth (#320). If there is a ring-like
continuous groove flaw, replace the vertical shaft with a new one.
(3) If there is a localized flaw like a pounding in the threaded portion,
make repairs to smooth it out, using set files, emery cloth (#320), etc.
(4) In regard to the secular wear of the bearing fitting portion, if the
inner race of the bearing slips, replace the vertical shaft with a
new one.
(5) If the pinion tooth surface is rough and is lightly worn, make repairs
with set files, emery cloth (#320), oil stone, etc.
(6) Measure the deflection of the shaft center in three places, the straight
portion at the end of the shaft, the middle portion of the shaft, and bearing fitting portion, with
the upper and lower bearing fitting portions supported by the measuring jigs. The deflection
should be limited to 5/100mm maximum. If the deflection is larger than that, replace the
vertical shaft with a new one.
4.3.2 Upper springs
(1) If there is even a broken or cracked upper spring, replace all of them
with new ones.
(2) Measure the free length of each of the upper springs. If any of them is
more than 1mm shorter than the dimension A, replace all of the
upper springs. Six upper springs equal in free length (dimension A)
are grouped as a set. (Refer to Table 4-2 )

4.4 Horizontal shaft system
4.4.1 Spiral gear
(1) The service life of the spiral gear depends on
conditions under which it is operated. As a rule of
thumb, the gear is serviceable until its tooth
thickness has been reduced to 1/3 of the normal
dimension if it is normally worn by even contact.
Replace the gear if its wear exceeds that extent.
(See Fig. 4-16)
(2) During initial operation or when the spiral gear has
been replaced, a transient wearing of the new gear
can occur. It is a normal phenomenon known as
"breaking-in." which is stopped after a while when the
contact of tooth surfaces has become smooth.
If the wear is excessively accelerated, something
wrong is suspected in the other parts. Check the
other parts.
(3) If there are burrs or high spots on the tooth surface, remove them with set files or emery
cloth (#320).
(4) Spalling (metal broken off in splinters) or pitting (marked with pits) on the tooth surface is
an indication that the gear oil has been deteriorated and should be changed.
4.4.2 Horizontal shaft
(1)If there is a localized flaw like a pounding on the
threaded portion, make repairs to smooth it out, using
set files, emery cloth (#320), etc.
(2)In regard to the secular wear of the bearing fitting
portion, if the inner race slips, replace the
horizontal shaft with a new one.
(3)If the key-way is wider because of wear, replace the
horizontal shaft with a new one.
4.4.3 Collar
If the diameter of the oil seal and collar sliding surface is more than 0.5mm worn than the
specified dimension, replace the collar with a new one.(Refer to Table 4-8)

4.4.4 Friction block
The life of the friction block cannot be sweepingly
determined, as it depends on the frequency of starts and
stops. If any of the linings 6mm thick is worn to 3mm,
replace all of the blocks.
(Fig. 4-18)
4.4.5 Friction pulley
Check the inside surface of the friction pulley for wear. If it is worn
more than 1mm, replace it with a new one.(Fig. 4-19)
The inside surface of the friction pulley allows machining up to
1mm deep to eliminate roughness.
4.5 Gear pump
4.5.1 Safety joint
Check the gear pump visually for distortion, wear, damage, etc.
without being removed, and replace if necessary.
4.5.2 Drive gear, driven gear and bush
If the shaft is producing abnormal sound, disassemble the gear pump, and check whether the
gears are in good contact, the spacing between the shaft and bush, wear or foreign
substances which might have been caught. If there are small scratches, repair the tooth
surfaces with an oil stone. If repairs cannot be made, replace.
4.5.3 Valve stem
When the capacity is insufficient or the suction is impossible, it is
often due to foreign substances caught by the valve stem.
Disassemble and thoroughly clean. In this case, it is necessary
that the position of the adjusting screw (dimension A of Fig. 4-20)
is confirmed beforehand (adjusting pressure 0.4MPa {4.0kg/cm2}).
If the screw is over-tightened, the pressure will become
needlessly high, and overload could result. If it is under-tightened,
a poor suction will result.

4.7 Brake equipment
The life of brake lining cannot be sweepingly determined, as it
varies widely, depending on the number of times it has been
used. It is therefore necessary to check the brake lining at
regular intervals. If the brake lining 10mm thick is worn to 5mm,
replace the brake lining with a new one.
4.8 Water supplying device
The water supplying device is designed to supply operating
water to the bowl opening and closing mechanism which
automatically discharges the sludge accumulated in the bowl.
If it is clogged by scale or the gasket or O ring is damaged, a
low water pressure or a low water flow rate will result, and the
mechanism might fail to open or close the bowl.
When the bowl is disassembled, be sure to check and clean the
water supplying device.

4.9 Inspection of Multi-Monitor for Function
Check to ensure that a detector alarm is properly output.
4.9.1 Leakage Monitor (LM)
The Leakage Monitor essentially determines that the outflow is abnormal as it detects the fall of
the pressure at the outlet side of the SELFJECTOR. Create this state by simulation.
(1) Check that the SELFJECTOR is in automatic operation and that the liquid is being fed.
(2) Open the pressure control valve at the light liquid outlet to reduce the pressure to a level the
resultant pressure drop (Δp) lower than preset.
(3) Check to ensure that an alarm is output after the elapse of the set time of the Hold timer.
4.9.2 Discharge Detector (DD)
! CAUTION
When alarm check is performed by the following procedures, the machine will come to a
stop without discharging the oil from inside the bowl. When the machine is restarted and
the sludge is discharged, the oil will flow out. Therefore, perform operations with due
consideration to safety.
(1) Check to ensure that the SELFJECTOR is in automatic operation and that the liquid is being
fed.
(2) Close the source valve of the operating water solenoid valve unit to stop the supply of all
operating water.
(3) Press the "DISCHARGE TEST" button of the control panel.
(4) Check to ensure that an alarm is output after the elapse of the discharge process time.
4.9.3 Water Detector (WD)
The Water Detector incorporated in the G-HIDENS type SELFJECTOR works in such a way that,
as separated water is collected to a predetermined level in the bowl, it detects an ensuing
pressure drop in the circulation line and issues a command signal to discharge separated water.
Inspect the Water Detector for function simulating this state of working.
(1) Check that the SELFJECTOR is in automatic operation and that the liquid is being fed.
(2) Open the back pressure valve in the circulation line to reduce the pressure to a level the
resultant pressure drop (ΔW) lower than preset.
(3) After the lapse of the time set on the hold timer, listen for the sound of discharge to check
that partial or total discharge of separated water from the bowl takes place.
Note that the Water Detector is a device provided in the GSH-1 automatic version only.

6 Causes of troubles and corrective steps
! WARNING
Before performing opening checks, check to ensure that the SELFJECTOR has come to a
complete stop. Whether the SELFJECTOR has come to a stop can be checked by watching the
safety joint section at the horizontal shaft gear pump side or the fan of the motor.
If the Discharge Monitor is provided, the stop of the SELFJECTOR can be known as well from
the illumination of LED (green) on top of the Multi-Monitor.
! CAUTION
When an alarm occurs, perform checks and remove the cause of the alarm before re-starting the
machine.

Oil leakage
When the SELFJECTOR fails to operation and causes either of the following phenomena, it
regards the phenomenon as "Oil leakage" and outputs an alarm.
(1) The treatment liquid (oil) flows out from the heavy liquid side.
(2) The treatment liquid (oil) flows out because of insufficient sealing of the sludge outlet of the bowl.
No opening of bowl
Despite the fact that the "discharge sludge" procedures were performed, no sludge has been
actually discharged. The SELFJECTOR regards it as a No opening of bowl and outputs an alarm.
Hidens alarm
The HIDENS (GSH-1 specification) version provided with circulation line and pressure sensor
produces a "WATER ABNORMALLY COLLECTED" signal in the case where a certain quantity of
separated water is frequently collected in the bowl with repeated issue of a discharge command.

6.1.4 Self-diagnostic fnction of detectors
6.1.4.1 Leakage Monitor (LM)
When fed with an extraordinarily high voltage (0.45
MPa), the pressure sensor recognizes it as a detector
failure and issues an alarm (LM alarm) after the lapse
of time set on the hold timer, and the error LED (red)
of the Multi-Monitor is illuminated (for approximately 2
seconds).
At the same time, an indication of the error appears in
the 7-segment display with corresponding error
number.
The error indication cannot be cleared until power is
turned off. Reset by turning off power and then on.
6.1.4.2 Discharge Detector (DD)
As a self-diagnostic function, the warning LED (red) on top of the Multi-Monitor is illuminated when:
① The SELFJECTOR speed output exceeds 2500 rpm
(where a circuit failure is suspected, for example)
② The proximity switch input signal is unstable
(where the switch may be out of position, for example).
Correct its position. This LED goes out as soon as its input signal has been stabilized.
Unlike the Leakage Monitor, no alarm signal is delivered when the LED lights.
(When adjusting and confirming the position of the proximity switch, refer to 5. Discharge Detector in
the Operation Manual 2. )
NOTE When the SELFJECTOR is in the process of being started or stopped, the Trouble display LED
may temporarily come on, but this should not be taken to mean that the Multi-Monitor is out of
order.
6.1.4.3 Water/Heavy Liquid Detector (W/H)
Like the Leakage Monitor, when fed with an extraordinarily high voltage (0.45 MPa), the pressure
sensor recognizes it as a detector failure and produces an alarm (LM alarm) after the lapse of time set
on the hold timer, and the error LED (red) of the Multi-Monitor is illuminated (for approximately 2
seconds). At the same time, an indication of the error appears with corresponding error number in the
7-segment display. The error indication cannot be cleared until power is turned off. Reset by turning
power off and then on.
