The battery pack is connected directly to the main board.

Wiring diagram - see drawing on page 46

Battery chemistry:

NiMH

Design:

PTC - protected against short circuit

Melt fuse - operating at 72 C

NTC - temperature measurement

The battery pack includes a circuit board with:

* Diodes

* Battery under voltage control - disconnects the battery

from the electronics when the battery voltage is too

low. This reduces the possibilities of reverse polarity.

* ID chip - an EEPROM containing information about

the battery pack (Remaining capacity, etc.)

To get (read) correct remaining capacity, the battery must be

fully charged before turning the transponder ON.

switched ON when the two marker dots are aligned. All other

positions are OFF.

Refer to information on page Figure 5 on page 16.

1 Switch the unit ON.

- Use a suitable screwdriver. Ensure the two marker

dots are aligned.


24 331869/D

- The unit will transmit bursts to indicate that it is

activated.

2 Each time the transponder is switched ON it will be reset

to the two default channels.

How to turn the transponder OFF

Note The cNODE® Mini must always be switched OFF when not in

use.

1 Switch the unit OFF.

Changing the transponder channel

If required, the channel setting may be changed. This is done as

follows:

By acoustic telemetry from a HiPAP or HPR 400 system - in

the transponder configuration program,

or

Via serial line/acoustic telemetry from TTC (change of

default channel)

For information about set-up of a transponder:

Refer to the APOS Instruction manual / APOS on-line help.

Pre-deployment checks

Before you deploy the transponder, you must:

1 Check that the battery contains sufficient power for the

proposed operation.

2 Before deployment, perform a visual inspection of the

transponder.

- The Vent screw and the Pressure relief valve must

be closed.

- The Charger connector must be fitted with a

dummy plug.

- The Signal connector must be fitted with an

external cable or a dummy plug.

3 Perform a functional check to ensure it will operate

correctly once it has been positioned on the seabed.

- Ensure the transponder replies to the correct

interrogation frequency.

The functional check can be performed as follows:

Transponder on deck – use TTC for cNODE® transponders.


28 331869/D

Transponder in water - use HiPAP or HPR 400 system. When

checking, lower the transponder on a rope over the vessel’s

side.

Refer to the APOS Instruction manual/APOS on-line help.

Mounting

The transponder may be secured to a subsea structure using

mounting brackets.

Deployment

Caution During deployment prevent the transponder from slamming against other solid objects.

When you deploy the transponder:

The unit must be positioned with the transducer upright.

Ensure a clear line of sight between the transponder’s head

and the ship’s transducer.

The transponder requires brackets to hold the transponder

securely in position.

Ready for operation

Once deployed, the transponder is ready for operation.

Operation


Recovery checks

1 After recovery switch the unit OFF.

2 Wash the unit thoroughly in warm fresh water to dissolve

any salt deposits and clean off any sand or silt.

3 As an extra precaution, it is recommended that the unit is

left to soak in fresh water to allow salt to dissolve and

diffuse from hard-to-reach areas, such as crevices around

O-rings, and between mating parts.

- Leave the unit to soak for 24 hours, or as long as

practical conditions allow.


331869/D 29

If a rechargeable unit is to be re-deployed imminently, put the

unit on charge.

Vent screw

The vent screw is used when charging the battery, to prevent

build-up of gases inside the cNODE® Mini. The vent screw can

be opened by hand, or use a suitable screwdriver.

Pressure relief valve

The ON/OFF switch also acts as a pressure relief valve. The

ON/OFF switch has two dual O-rings and work as follows:

One O-ring will seal only when the switch is pressed fully

into its seat.

The other O-ring will seal, even with the switch pushed

approximately 2 mm outwards.

If the switch rest in a not fully home position, or they feel

springy when pushed in place, it means there is some

over-pressure inside the cNODE® Mini.

If the pressure becomes too big, the valve will vent. When the

pressure has been relieved, the switch can be pushed back into

position.


30 331869/D

How to charge the battery

The battery is charged inside the cNODE® Mini. This is

connected with some risk, so please read the information below,

and follow the charge procedure carefully.

Warning When you are charging the battery ensure the following: - Good ventilation and stable temperature.

- The transponder is not covered. - No open fire, sparks or smoking in the area.

Before you start charging

NiMH batteries can generate some hydrogen and oxygen gas,

the amount depending on certain conditions. Most often this

generation occurs during charging. To prevent build-up of

gasses inside the cNODE® Mini, there are 2 countermeasures.

1 Vent screw.

Caution The vent screw must be open during charging.

a Unscrew the vent screw until you feel some resistance

(a nylon washer is forced against a metal surface).

The O-ring is now visible.

b Hold the cNODE® Mini in an upright position while

you do this, so that any water droplets caught around

the vent screw comes out, rather than going inside the

cNODE® Mini.

c When the charging is complete - tighten the vent screw

by hand only, until you feel a rather sudden resistance.

(an internal axial O-ring hits a metal surface,

compresses 0.3 mm, before 2 metal surfaces meet). The

main flat circular surface of the end cap should now

align with the edge of a semicircular groove that runs

all around the vent screw. This is to visually confirm

that the vent screw has been properly tightened.

2 Safety valve - The ON/OFF switch also acts as a safety

valve.

a In case of a pressure build-up inside the cNODE®

Mini, the safety valve will pop open when the pressure

reaches 0.1-0.2 bar. Under normal conditions this valve

will never operate, as any gas build-up is released

through the manually opened vent screw.

Charge modes

Initialization (charger measures battery status)

Fast charge (charge mode)

Complete charge (Trickle charge – battery fully charged)

Error

Status LEDs

There are three status LEDs on the charger:

A, B and C - for charging of the three battery strings (A, B, C)

individually.

Charge procedure

1 Switch OFF the transponder.

2 Climatize the transponder.

- The battery must have a temperature between 5 C and

40 C. Recommended charging temperature is 25 C.

Note Charging cold batteries (below 10 C) will give less capacity

and shorter service life.

3 Manually vent the transponder - use the vent screw.

4 Connect the charger plug to the cNODE® Mini.

5 Connect Power supply to mains (110 Vac or 220 Vac).

6 Switch on the charger.

- All status LEDs - constant orange light.

7 The charging will start:

Stage 1 - Charger measures the battery status

(Initialization mode):

All status LEDs - constant yellow light.


32 331869/D

- If the battery temperature is out of range, (ref point 2

in this procedure), the charger will show error mode.

* Status LED - flashing orange / green light.

Refer to the Action for Error mode below.

Stage 2 - Fast charge mode

All status LEDs - constant orange light.

Caution Ensure that all (A, B, C) status LEDs show fast charge mode after a few seconds.

- Fast charge - the charger will measure temperature,

voltage and time during this mode.

Stage 3 - Detection of fully charged battery:

All status LEDs - green light with yellow flash for 1

minute.

Methods for detection of fully charged battery:

- Temperature rise (dT/dt)

- maximum time.

When one of these criteria occur, the charger will stop the

fast charge mode.

- If the battery temperature reaches the maximum

temperature (60 C), the charger will show error

mode.

* Status LED - flashing orange / green light.

Refer to the Action for Error mode below.

Action for error mode:

a. Stop charging.

b. Climatize the battery.

Ref to point 2 in the charge procedure on page 31

c Start charging again.

Stage 4 - Completely charged battery and trickle charge

(Complete charge mode)

All status LEDs - constant green light.


331869/D 33

Caution Ensure that all (A, B, C) status LEDs show complete mode.

When the battery is fully charged, the charger will start trickle

charge the battery.

Note It is not recommended that the battery is trickle charged for a

long time. It is better to start fast charge again to top the battery

just before operation.

The transponder is now ready for operation!

8 Switch off the charger.

9 Disconnect charger plug from the cNODE® Mini

transponder (external connector).

10 Ensure that the ON / OFF switch and the vent screw are in

closed position.

The recommended temperature range for long-term storage of

the rechargeable battery cells is -20 degrees C to +35 degrees

C*. Stored capacity decreases over time due to the self-

discharge of the rechargeable battery cells.

How to replace the battery pack

The battery is build into the chassis. To replace it, follow the

procedure below:

1 Open the transponder.

Refer to page 19 for details.

2 Disconnect the battery connector. The connector is placed

at the top of the battery.

3 Pull the battery out.

- The battery is fastened to the electronic chassis with

double-faced tape.

4 Assembly is the reverse of dismantling.


34 331869/D

Battery storage

Store the battery in a suitable environment if the unit is not to be

re-deployed in the near future.

The recommended temperature range for long-term storage of

the rechargeable battery cells is -20° C to +30° C*. Stored

capacity decreases over time due to the self-discharge of the

rechargeable battery cells.

Self-discharge is dependent on temperature and the higher the

temperature the greater the self-discharge over time. Long-term

storage has no permanent effect on capacity. Loss in capacity

due to self-discharge is reversible.

*The relative humidity should be < 50%.

Maintenance

331869/D 35

6 MAINTENANCE The following maintenance is normally required:

Washing the unit.

Lubrication of the external connector

Caution Electronic devices can be destroyed by static electricity. It is therefore essential that full protection against static is practised by service engineers.

Although the unit is resistant to mechanical vibration and shock, every effort must be made to avoid careless

handling when the unit is in use or being transported.

O-rings

Whenever the transponder is opened and the O-rings are

exposed, precautions must be taken. This includes keeping the

O-rings and mating surfaces free of dust and debris. If any of the

mentioned surfaces is to be cleaned, it is important to use lint-

free objects. Q-tips must never be used to clean areas anywhere

near an O-ring.

When inserting an O-ring, make sure the surface is clean, and

that it is covered with a thin film of silicone grease.

Preventive maintenance

Preventive maintenance is limited to keeping the unit clean.

Caution Do not use high pressure water as this will damage the transducer face.

Remove all traces of salt and debris.

Before any connectors are disconnected, ensure the

surrounding areas are dry.

Inspect the unit for damage at regular intervals. Pay particular

attention to the transducer surface. This is manufactured of a

synthetic rubber material, and can easily be damaged.

How to open the transponder

Before you open the unit:

1 Wash the unit thoroughly in fresh water, and dry off any

moisture on the outside.

2 Place the transponder horizontally on a flat, clean work-

bench, and support it so it cannot roll off.

3 Disconnect any external cable.

4 Turn OFF the transponder.

Maintenance

331869/D 37

Opening the unit:

The unit is held together by a lock cord inserted (see photo

above) in a groove between the tube and the end cap /

transducer. Access to the cord is via two clearly visible slots at

either end of the transponder tube. The cord is inserted by hand,

and it is removed by picking up the free end visible in one slot,

and pushing the other end (visible in the other slot).

Caution Take care not to use sharp objects that can damage the anodized surface of the aluminium.

Caution Observe the 5 mm orientation peg at either end of the tube. When pulling apart, make sure to keep this

orientation until parts are completely free from each other. Forceful twisting of the parts relative to each other while the internal parts are still mated, will

damage the unit.

5 Remove the retaining cord between the end cap and the

tube, as described above.

6 Carefully pull the end cap from the unit.

- There is a padding between the end cap and the

battery, to secure the battery.


38 331869/D

- Take care when replacing / removing the padding, to

avoid damaging the cables.

7 The end cap is fitted with two guiding pins that fit into

two holes in the electronic chassis.

See drawing on page 45

8 Remove the lock cord between the transducer and the

tube, as described above.

9 Pull the tube from the transducer. Support the transducer

as it is withdrawn.

- All internal parts are now clearly visible and

accessible.

10 Once the O-ring is clear of the housing, the transducer and

electronics chassis may be removed.

Replacement of the transducer

The transducer is a sealed unit and cannot be opened. If the unit

is not working, the whole unit must be replaced.

1 Open the transponder.

Refer to page 36 for details.

Maintenance

331869/D 39

(Cd30111)

2 Remove the transducer from the electronics chassis

(2 fixing screws).

3 Assembly is basically the reverse of dismantling.

Note The transducer part contains a matching transformer.

How to assemble the transponder

Before you start:

1 Inspect the O-rings and backup rings for damage. If in

doubt, or if they have been used for more than one year,

they should be replaced.

2 Place the new bag of silica-gel desiccant into the housing

to absorb any humidity that may have entered the unit

while it was open.

3 Ensure all surfaces, O-rings and backup rings are

completely clean and then wipe a thin film of silica-gel

over the rings and mating surfaces.

Caution Ignoring these recommendations may result in flooding of the transponder unit.

Assembling:

Assembly is the reverse of disassembly.

Handling the O-rings:


40 331869/D

1 Check the condition of the rings and carry out any

necessary replacements.

2 Ensure the O-ring surfaces are clean and free from any

dust, debris or old grease.

3 Lightly grease the rings prior to assembly using Molykote

33 grease or similar.

4 Re-fit the O-rings (see figure below).

2 ringsO- 2 ringsO-

End cap

Retaining cord

(Cd6418)

Lubrication of the subsea connectors

The two 8-pin connectors should be kept free from grit and dirt.

The manufacturer recommends lubricating the pins with:

Molykote 44M silicone based grease.

You must not use silicone based sprays like 5-55, WD-40

or similar. These will degrade the rubber fused around the

metal pins.

Note Use it sparingly; half a match-head dose per contact is

adequate.
