The new Atlantic Sea control system incorporates the very latest in powerful control system technology as well as highly intelligent programming. At the core of the control system is the all new 32 bit Programmable Logic Controller (PLC); this device provides constant supervision of your water maker. Should any problem arise during operation this intelligent hardware will first analyze if this fault could possibly damage the water maker, if so it classifies this error as ‘critical’ and performs a rapid shutdown of the unit to prevent damage, rapid shutdowns usually require 10 seconds to complete. However, if the controller deems the current problem as ‘non critical’ the water maker is allowed to continue operating; meanwhile the control system will alert operators that service is required by beeping and displaying a warning notification on the system touch screen; the controller will continue to monitor the situation closely and if the current problem should become ‘critical’ the control system will take action to prevent damage and rapidly shut the water maker down. The reason for the shutdown will be displayed on the system touch screen. This manual has been written to help walk you through the various features offered by the installed control system. During fault situations your water maker control system produces messages to help point you to the root cause of the problem; contained within this manual is a list of trouble shooting tips based on these messages; each tip will detail the likely possibilities which resulted in the call for the associated fault message. The new Atlantic Sea control system also comes with an available Modbus interface. This Modbus interface can be used to create an open communications interface between locally hosted control systems and the Atlantic Sea water maker. Via the Modbus interface it is possible to monitor all control system inputs and outputs; it is also possible to monitor data normally displayed on the control system touch screen including alarm information, performance information, system pressure information and salinity information. For further information on the Modbus interface, please refer to the Atlantic Sea Modbus Specification documentation. The new Atlantic Sea control system also comes with an available Ethernet internet interface. This interface can be used to remotely monitor and control the Atlantic Sea water maker for any computer with browser software within the locally hosted IP network. The system can also be modified to accept remote connections from outside the locally hosted network via use of static IP addressing. When used the internet interface performs as a direct simulation of the system HMI interface, and no special programming is required to facilitate its use. For further information on the internet interface, please refer to the Atlantic Sea Internet Interface Specification documentation.

2.2 Motor and Pump Rotation Checks

Step 1.

Once at the motor jog screen press the booster pump button to jog the Booster Pump. Once pressed a command will be sent to the drive system which slowly accelerates the pump motor for a few seconds and then stops it, therefore it is best to carry out this procedure with two people, one who can activate the jog command and one who can watch the pump motor rotation direction. If the Booster Pump motor spins in the direction indicated on the pump motor coupler then proceed to step 2; if the Booster Pump motor does not spin in the correct direction refer to the ‘VFD Controls and Setup’ section of this manual for further instructions on how to change the motor rotation direction. Once you have completed the steps required to change motor rotation direction detailed in the ‘VFD Controls and Setup’ section confirm motor direction is correct by returning to this commissioning screen and running the jog procedure one more time before proceeding any further.

Step 2.

Once correct Booster Pump rotation has been confirmed press the High Pressure Pump button to jog the High Pressure Pumps. Once pressed a command will be sent to the drive systems which slowly accelerate the pump motors for a few seconds and then stops them, therefore it is best to carry out this procedure with two people, one who can activate the jog command and one who can watch the pumps motor rotation direction. If the High Pressure Pump motors spin in the direction indicated on the pump motor casings then proceed to step 3; if the High Pressure Pump motors do not spin in the correct direction refer to the ‘VFD Controls and Setup’ section of this manual for further instructions on how to change the motor rotation direction. Once you have completed the steps required to change motor rotation direction detailed in the ‘VFD Controls and Setup’ section confirm motor direction is correct by returning to this commissioning screen and running the jog procedure one more time before proceeding any further.

Step 3.

Once correct High Pressure Pump rotation has been confirmed press the ISave Pump button to jog the ISave Pump(s). Once pressed a command will be sent to the drive system which slowly accelerates the pump motor for a few seconds and then stops it, therefore it is best to carry out this procedure with two people, one who can activate the jog command and one who can watch the pump motor rotation direction. If the ISave Pump motor spin in the direction indicated on the ISave Pressure Exchanger casings then proceed to step 3; if the ISave Pump motor do not spin in the correct direction refer to the


Project:

Doc: Version:



‘VFD Controls and Setup’ section of this manual for further instructions on how to change the motor rotation direction. Once you have completed the steps required to change motor rotation direction detailed in the ‘VFD Controls and Setup’ section confirm motor direction is correct by returning to this commissioning screen and running the jog procedure one more time before proceeding any further.

Step 4.

Once correct ISave Pump rotation has been confirmed press the Product Pump button to jog the Product Pump. Once pressed a command will be sent to the contactor which rapidly accelerates the pump motor for a ¼ of a second and then stops it, therefore it is best to carry out this procedure with two people, one who can activate the jog command and one who can watch the pump motor rotation direction. If the Product Pump motor spins in the direction indicated on the pump motor casing then proceed to step 3; if the Product Pump motor does not spin in the correct direction refer to the ‘VFD Controls and Setup’ section of this manual for further instructions on how to change the motor rotation direction. Once you have completed the steps required to change motor rotation direction detailed in the ‘VFD Controls and Setup’ section confirm motor direction is correct by returning to this commissioning screen and running the jog procedure one more time before proceeding any further.

Once these tests have been completed and correct rotation of all connected pumps has been confirmed you may exit commissioning mode by pressing the arrow in the top left corner five times. This will return you to the main operations menu.

3.2 Booster Pump Minimum Inlet Pressure (Absolute) [Range = > 10]

This value determines the alarm level associated with the booster pump inlet pressure. During normal operation the booster pump will pull a small vacuum at its inlet, an excessive vacuum can indicate a feed water problem, when an excessive vacuum is detected the system will not shut down the water maker but it will indicate the problem by flashing the booster pump inlet pressure bar on the feed system monitors page.

Typical values entered here are 10 PSI [ABSOLUTE]

3.3 Booster Pump Maximum Inlet Pressure (Absolute) [Range = <30]

This value determines the alarm level associated with the booster pump inlet pressure. The water maker can function with either just a flooded line or a small amount of positive pressure feeding the booster pump. Too much positive pressure however will result in over pressurization of system components once the system activates the booster pump, hence the amount of positive pressure being feed into the booster pump must be within specifications. If this inlet pressure is above specifications the system will not shutdown the water maker but it will indicate the problem by flashing the booster pump inlet pressure bar on the feed system monitors page.


Enter desired set-point value here

Enter Value and press here



Project:

Doc: Version:



3.4 Booster Pump Minimum Outlet Pressure [Range = > 20 &< 45]

This value determines the alarm and shutdown level associated with the performance output of the booster pump. During normal operation the booster pump output should be in the range of 60 to 80 PSI, when the booster pump output falls below the value set here it is usually because of either mechanical failure within the booster pump, booster pump motor overload trips, or the booster pump has lost prime and is now running dry. Once the system detects the output pressure of the pump has dropped below the value specified here, it will generate an alarm that results in complete shutdown of the water maker.

Typical values entered here are 20 PSI

3.5 Booster Pump Maximum Outlet Pressure [Range = > 60 &< 100]

This value determines the alarm level associated with the performance output of the booster pump. During normal operation the booster pump output should be in the range of 60 to 80 PSI, when the booster pump output rises above the value set here it is usually because of either flow from the pump has been restricted, or inlet pressure into the water maker is above specifications. Once the system detects the output pressure of the pump has exceeded the value specified here, it will not shutdown the water maker generate an alarm that results in complete shutdown of the water maker but it will indicate the problem by flashing the Media Filter Inlet pressure bar on the feed system monitors page.


3.6 Booster Pump Output Error Maximum Operation Time [Range = > 30&<150]

This value determines how many seconds the control system will wait before acknowledging a booster pump output error fault, for example when a value of ‘10’ is entered, the system will not trigger a shutdown unless the output of the booster pump has been detected as below the value set in 4.4 consistently for 10 seconds. This entry field helps eliminate system shutdowns due to momentary fluctuations in booster pump outlet pressure

Typical values entered here are 45 SECONDS

Doc: Version:



3.7 ISave Pump Output Error Maximum Operation Time [Range = > 10 &< 30]

This value determines how many seconds the control system will wait before acknowledging an ISave pump output error fault, for example when a value of ‘10’ is entered, the system will not trigger a shutdown unless the output of the ISave pump has been detected as below the pre-set value consistently for 10 seconds. This entry field helps eliminate system shutdowns due to momentary fluctuations in ISave pump outlet pressure


3.8 Maximum 20u Filter Differential Pressure [Range = > 10 &< 35]

This value determines at what differential pressure the control system will alert you that the 20u cartridge filter requires replacement, as the cartridge filter begins to fill with dirt, its differential pressure will increase, if a filter is allowed to run with too high a differential pressure bypass can occur, this is potentially dangerous to the health of the water maker therefore it is advised to select a value based on the filter manufactures recommendations. The value also drives the interactive graphic shown on the P&ID and ‘Feed System Monitors’ page, as the filter becomes more and more clogged this graphic will change to give you a visual indication of the current dirt level.

3.10 Minimum Feed system Flow Rate [Range = > 300 &< 350]

This value determines at what feed flow rate the control system will alert you that the system is experiencing difficulty. During normal operation the control system would expect to see approximately 310 GPM. If the control system sees flow drop below the value stated here it will not shutdown the water maker but it will indicate the problem by flashing the feed system flow rate bar on the feed system monitors page, it will also raise a ‘System Performance Monitor’ alarm indicating the detected problem. If system flow drops below the value specified here it could indicate a high pressure pump or ISave pump failure is imminent.

3.11 Maximum Feed system Flow Rate [Range = > 350 &<400]

This value determines at what feed flow rate the control system will alert you that the system is experiencing difficulty. During normal operation the control system would expect to see approximately 310 GPM. If the control system sees flow rise above the value stated here it will not immediately shutdown the water maker but it will indicate the problem by flashing the feed system flow rate bar on the feed system monitors page, it will also raise a performance warning (See Performance Warning Messages) indicating the detected problem. If system flow continues to exceed the value specified here for 2 minutes the control system will shut-down the water maker. High flow rates can be an indication of a breached line/significant leak, therefore after 2 minutes action is taken to protect the integrity of the location in which the water maker is housed.

3.12 Minimum ISave System Flow Rate [Range = < 100]

This value determines at what ISave flow rate the control system will alert you that the system is experiencing difficulty. During normal operation the control system would expect to see approximately 175 GPM. If the control system sees flow drop below the value stated here it will not shutdown the water maker but it will indicate the problem by flashing the feed system flow rate bar on the feed system monitors page, it will also raise a ‘System Performance Monitor’ alarm indicating the detected problem. If system flow drops below the value specified here it could indicate that the ISave back pressure regulator is not set correctly and mixing could occur resulting in lowered system production output.

If the control system sees flow rise above the value stated here it will not immediately shutdown the water maker but it will indicate the problem by flashing the feed system flow rate bar on the feed system monitors page, it will also raise a performance warning (See Performance Warning Messages) indicating the detected problem. If system flow exceeds the value specified here it could indicate that the ISave back pressure regulator is not set correctly and over-flushing could occur resulting in shortened pre-filter system life.

3.14 Minimum High PressurePump Inlet Pressure[Range = > 20 &< 70]

This value determines what the minimum operating inlet pressure of the high pressure pump is. If the unit is in operation but fails to reach or exceed the pressure set-point established here the control system will perform a rapid shutdown of the water maker system to protect system components from damage and will alert the user of this error by raising a System Critical Fault Message (See System Critical Fault Messages)

Typical values entered here are 29 PSI in all pump applications

3.15 Maximum High PressurePump Inlet Pressure[Range = > 45 &< 80]

This value determines what the maximum operating inlet pressure of the high pressure pump is. If the unit is in operation but exceeds the pressure set-point established here the control system will perform a rapid shutdown of the water maker system to protect system components from damage and will alert the user of this error by raising a System Critical Fault Message (See System Critical Fault Messages)


3.16 Minimum High PressurePump OutletPressure[Range = > 300 &< 350]

This value determines what the minimum operating pressure of the high pressure pump system is. If the unit is in operation but fails to reach or exceed the pressure set-point established here the control system will initially alert the user of this error by raising a performance warning (See Performance Warning Messages), if after a predetermined time the operator has failed to rectify the situation the control system will perform an automatic rapid shutdown of the water maker to protect system components from damage.

Operation over these hours is allowed, but is not recommended.

Typical values entered here are 2000 Hrs in all applications

3.21 Maximum Individual Membrane Element Differential Pressure [Range = >5 &<20]

This value determines how the controller re-acts to membrane differential pressures. As a membrane becomes fouled the differential pressure across the membrane inlet and outlet ports increases, the control system can be used to monitor the current fouling status of the membranes but this feature is only provided as a visual aid to the operator.

Typical values entered here are 12 PSI in all membrane applications

3.22 Maximum Expected Clean Membrane Element Differential Pressure [Range = >1&<5]

This value determines how the controller re-acts to membrane differential pressures. New from the manufacturer a membrane generates a differential pressure across the membrane inlet and outlet ports. It is important that this initial value be established and correctly set within the control system to allow for correct membrane fouling information.

Typical values entered here are 3 PSI in all Dow &Toray membrane applications

3.23 Maximum Permeate Line Pressure [Range = > 45]

This value determines the alarm level at which the control system will begin notifying you of permeate line back pressure problems, during normal operation the permeate line should never see in excess of 50 PSI of back pressure, excessive back pressure can cause cracking of the carbon filter housings which can lead to leaks and loss of production

3.24 Acceptable Maximum Salinity Level [Range = > 500 &< 1800]

This value stated in uS/cm determines at what product water conductivity level the system will activate the diversion valve and UV sterilizer (if fitted). It should be noted that during normal operation activation of the diversion valve will only take place once the system has completed start up, and system pressure has been raised above minimum. Once all of these conditions are met, the water maker will begin a 2 minute delay, this delay is provided to allow the product water salinity to drop down to levels that can be accurately monitored, after this delay has expired the control system will begin actively monitoring the product water salinity. Once the product water measured conductivity drops below the number inputted here, the water maker deems the water as acceptable.

Typical values entered here are 1200 uS/cm in all applications

3.25 Acceptable Minimum Salinity Level [Range = > 50 &< 150]

This setting allows you to determine what minimum salinity level from the salinity probe will be accepted. Domestic systems cannot produce product water with salinity lower than the value entered here, therefore any readings below this value causes the water maker control system to reject the salinity probe input under the suspicion that the salinity probe has been removed from the system pipe work and is currently sitting in air. It should be noted that the system has to be fully operation and the salinity reading must be consistently below the value set here for 30 seconds before the system will re-act. Once it has been determined that the salinity probe has been removed from the system pipe work the control system will drop into ‘Manual Salinity Control Operation’ (See Section 6.8)

Typical values entered here are 100 in domestic water applications

3.26 Fresh Water Flush Time [Range = > 300 &< 900]

The value entered here (in seconds) determines how long the fresh water system will operate for once active pumps have been stopped by pressing the ‘Auto-Stop’ button. It should be noted that Fresh Water Flush mode can only be activated when shutting the system down using the “Auto-Stop’ button, any other method of shutdown excluding automatic backwashes will de-activate the Fresh Water Flushing Mode for that occurrence. Once the allotted time has expired the fresh water flush system will enter a dormant mode for 7 days before repeating the flushing cycle. The dormant cycle of 7 days is not alterable by the system user.

Typical values entered here are 600 Seconds in all applications


Project:

Doc: Version:



3.27 Minimum Allowable Fresh Water Flush Pressure [Range = > 15 &< 60]

This value determines the alarm level associated with Fresh Water Flushing faults. In order for the fresh water flush system to operate correctly there must be sufficient pressure in the system to ensure the high pressure pump bypass check valve opens. If there is not sufficient pressure to allow this, the control system will raise an alarm to notify the operator that Fresh Water Flushing is not taking place as designed. It should be noted that during a Fresh Water Flushing Cycle the incoming fresh water pressure must be below the value entered here consistently for 60 seconds before the control system will re-act to it.

Typical values entered here are 30 PSI in all applications

3.28 Low Pressure Valve Actuation Time [Range = > 10 &< 25]

The value entered here (in seconds) determines how long the control system will wait for movement of an automated low pressure valve to complete. If the correct feedback from the valve has not been received before this time expires, the system will either generate a performance warning, or shutdown the unit and generate a fault warning, the action taken depends on what operational state the water maker was in at the time of failure. It should be noted that entering a value that is less than the stated actuator actuation time will result in constant errors from the control system. This value is pre-set at DSRC and should not be changed unless you are instructed to do so by a member of DSRC technical support staff.


3.29 ISave By-pass Valve Actuation Time [Range = > 5 &< 35]

4.2 Booster Pump Minimum Inlet Pressure (Absolute) [Range = No Limit]

This value determines the alarm level associated with the booster pump inlet pressure. During normal operation the booster pump will pull a small vacuum at its inlet, an excessive vacuum can indicate a feed water problem, when an excessive vacuum is detected the system will not shut down the water maker but it will indicate the problem by flashing the booster pump inlet pressure bar on the feed system monitors page.

4.3 Booster Pump Maximum Inlet Pressure (Absolute) [Range = No Limit]

This value determines the alarm level associated with the booster pump inlet pressure. The water maker can function with either just a flooded line or a small amount of positive pressure feeding the booster pump. Too much positive pressure however will result in over pressurization of system components once the system activates the booster pump, hence the amount of positive pressure being feed into the booster pump must be within specifications. If this inlet pressure is above specifications the system will not shutdown the water maker but it will indicate the problem by flashing the booster pump inlet pressure bar on the feed system monitors page.


4.4 Booster Pump Minimum Outlet Pressure [Range = No Limit]

This value determines the alarm and shutdown level associated with the performance output of the booster pump. During normal operation the booster pump output should be in the range of 60 to 80 PSI, when the booster pump output falls below the value set here it is usually because of either mechanical failure within the booster pump, booster pump motor overload trips, or the booster pump has lost prime and is now running dry. Once the system detects the output pressure of the pump has dropped below the value specified here, it will generate an alarm that results in complete shutdown of the water maker.


4.5 Booster Pump Maximum Outlet Pressure [Range = No Limit]

This value determines the alarm level associated with the performance output of the booster pump. During normal operation the booster pump output should be in the range of 60 to 80 PSI, when the booster pump output rises above the value set here it is usually because of either flow from the pump has been restricted, or inlet pressure into the water maker is above specifications. Once the system detects the output pressure of the pump has exceeded the value specified here, it will not shutdown the water maker generate an alarm that results in complete shutdown of the water maker but it will indicate the problem by flashing the Media Filter Inlet pressure bar on the feed system monitors page.

4.6 Booster Pump Output Error Maximum Operation Time [Range = No Limit]

This value determines how many seconds the control system will wait before acknowledging a booster pump output error fault, for example when a value of ‘10’ is entered, the system will not trigger a shutdown unless the output of the booster pump has been detected as below the value set in 4.4 consistently for 10 seconds. This entry field helps eliminate system shutdowns due to momentary fluctuations in booster pump outlet pressure


4.7 ISave Pump Output Error Maximum Operation Time [Range = No Limit]

This value determines how many seconds the control system will wait before acknowledging an ISave pump output error fault, for example when a value of ‘10’ is entered, the system will not trigger a shutdown unless the output of the ISave pump has been detected as below the pre-set value consistently for 10 seconds.

If system flow drops below the value specified here it could indicate a high pressure pump or ISave pump failure is imminent.

4.11 Maximum Feed system Flow Rate [Range = No Limit]

This value determines at what feed flow rate the control system will alert you that the system is experiencing difficulty. During normal operation the control system would expect to see approximately 310 GPM. If the control system sees flow rise above the value stated here it will not immediately shutdown the water maker but it will indicate the problem by flashing the feed system flow rate bar on the feed system monitors page, it will also raise a performance warning (See Performance Warning Messages) indicating the detected problem. If system flow continues to exceed the value specified here for 2 minutes the control system will shutdown the water maker. High flow rates can be an indication of a breached line/significant leak, therefore after 2 minutes action is taken to protect the integrity of the location in which the water maker is housed.

4.31 Product Diversion Valve Actuation Time [Range = No Limit]

The value entered here (in seconds) determines how long the control system will wait for movement of a the product diversion valve to complete. If the correct feedback from the valve has not been received before this time expires, the system will either generate a performance warning, or shutdown the unit and generate a fault warning, the action taken depends on what operational state the water maker was in at the time of failure. It should be noted that entering a value that is less than the stated actuator actuation time will result in constant errors from the control system. This value is pre-set at DSRC and should not be changed unless you are instructed to do so by a member of DSRC technical support staff.


4.32 ISave Pump Minimum Discharge Pressure [Range = No Limit]

The value entered here (in PSI) determines the minimum allowable ISave discharge pressure. If discharge pressures fall below this set-point the control system will initiate a rapid shutdown of the system and alert the user by presenting a system Critical Error Fault Message (Please see System Critical Fault Messages)


4.33 ISave Pump Maximum Discharge Pressure [Range = No Limit]

The value entered here (in PSI) determines the maximum allowable ISave discharge pressure. If discharge pressures rise above this set-point the control system will initiate a rapid shutdown of the system and alert the user by presenting a system Critical Error Fault Message (Please see System Critical Fault Messages)

4.34 Valve BF-1004 Left Closed Pressure Detection Limit [Range = No Limit]

During normal operation the control system measures differential pressures across various sections of system pipework, this is done to determine if manual valves located within this pipework section that provide no position feedback to the control have been positioned correctly. If differential pressures across these sections of pipe work exceed the values set here (in PSI) the control system can safely establish that the system pipe work manual valves are not positioned correctly and can shut the system down safely thus preventing any damage

Typical values entered here are 50 PSI on all systems

4.35 Valve BF-1000 Left Closed Pressure Detection Limit [Range = No Limit]

During normal operation the control system measures differential pressures across various sections of system pipework, this is done to determine if manual valves located within this pipework section that provide no position feedback to the control have been positioned correctly. If differential pressures across these sections of pipe work exceed the values set here (in PSI) the control system can safely establish that the system pipe work manual valves are not positioned correctly and can shut the system down safely thus preventing any damage


4.36 Maximum Allowable System Brine Pressure (PSI) [Range = No Limit]

This value (in PSI) determines at what detected pressure the emergency brine monitoring system will trigger an emergency brine isolation protocol event. This value should NOT be altered unless specifically told to do so by a Danfoss Sea Recovery Engineer. Altering this value could cause significant damage to the system in an emergency brine blockage event.

4.40 System Automatic Pressure Control Dead Band Size (PSI)

During automatic system pressure control operation the control system is constantly trying to keep system pressure at the desired set-point, to prevent the system from continuously hunting back and forth around the desired pressure set-point the control algorithm has a dead band setting. This setting allows the control system to pause automatic pressure control providing the system operation pressure is within +/- the value established here. For example if 30 PSI is set, the control system will attempt to reduce system operational pressures to the desired set-point (i.e. 975 PSI). Providing the operational system pressure is within +/- 15 PSI of the desired set-point the auto pressure control algorithm with pause to prevent hunting, meaning system pressures will range between 960 to 990 PSI before any further automatic pressure control action is taken.

4.44 High Pressure Pump Minimum Allowable Speed [Range = No Limit]

This value (in RPM) determines at which operation point the control system will stop automatic pressure control and rapidly shutdown the water maker. This setting comes into effect when automatic pressure control is reducing the RPM of the high pressure pumps in an attempt to keep system pressure below the threshold set-point. If the high pressure pumps are requested to slow down to this minimum allowable speed this indicates something has gone seriously wrong with the high pressure system and represents the possibility of high mixing within the ISave device. At this point the system must be shutdown to avoid any damage

Typical Values set here are 600 RPM in all applications

4.45 Control Off Period For Auto Pressure Decrease [Range = No Limit]

This value (in Seconds) determines the sample and processing rate of the automatic pressure control algorithm, the algorithm samples system data and acts upon this data after this control period has expired, this control period is only used when the algorithm is assessing the system pressure and detects that a reduction in pressure is required.

Typical values entered here are 5 seconds in all applications

4.46 Auto Pressure System Processing Delay Time [Range = No Limit]

This value (in Seconds) determines the processing delay time required by the automatic pressure control algorithm, the algorithm samples system data and acts upon this data after this control period has expired, this control period is always used and system pressure increase or decrease requests must be present for this period of time before the control algorithm will act to correct them.


4.47 ControlOff Period For Auto Pressure Increase [Range = No Limit]

This value (in Seconds) determines the sample and processing rate of the automatic pressure control algorithm, the algorithm samples system data and acts upon this data after this control period has expired, this control period is only used when the algorithm is assessing the system pressure and detects that an increase in pressure is required.


4.48 Booster Pump Initial Requested PID Output Pressure [Range = No Limit]

4.50 ISave Device Speed Triggering Close Of Air Bleed Valve [Range = No Limit]

This value (in RPM) determines which target output speed of the ISave device will trigger the closing of the system membrane air bleed valve. During automatic start up this valve is always open. However as the ISave device begins to accelerate this valve must be closed to prevent cavitation of the ISave pressure exchanger.


4.51 ISave Pump Stage 2 Requested Rotation Speed [Range = No Limit]

This value (in RPM) determines the target output speed of the ISave energy recovery device during the second stage of automatic system start up. Once required the control system will steadily accelerate the ISave device up to this requested speed which completes the start-up process for the ISave device


4.52 Membrane Air Bleed Purge Time Stage 1 [Range = No Limit]

This value (in Seconds) determines how long the control system will suspend automatic start-up of the system to allow air within the high pressure system to be purged. This delay time is used only in stage 1 of system start up and delays the initial activation of the ISave device until air has been purged.


4.53 Membrane Air Bleed Purge Time Stage 2 [Range = No Limit]

This value (in Seconds) determines how long the control system will suspend automatic start-up of the system to allow air within the high pressure system to be purged. This delay time is used only in stage 2 of system start up and delays the acceleration of the ISave device up to stage 2 speeds until remaining air has been purged from the system using the over flush technique.

4.54 High Pressure Pump Requested Rotation Speed [Range = No Limit]

This value (in RPM) determines the target output speed of the High Pressure pumps. Once required the control system will steadily accelerate the High Pressure Pumps up to this requested speed which completes the start-up process for the High Pressure Pumping System


4.55 Booster Pump Final Requested PID Output Pressure [Range = No Limit]

This value (in PSI) determines the target output pressure of the system booster pump during the final stage of automatic system start up. Once activated the control system will steadily decelerate the booster pump until this requested pressure is achieved at the input of the High Pressure pumps


4.56 ISave Minimum Pressure Before Power Off [Range = No Limit]

This value (in PSI) determines the maximum target pressure of the membrane system allowable before system shutdown can complete. During automatic shutdown the control system initially stops the high pressure pump, and then decelerates the ISave device back down to speeds set in stage 1 of the ISave start-up (4.49). Once this target RPM has been reached the control system delays further shutdown of the unit until system membrane pressures have dropped to below the value set here. Once this target pressure has been released the control system will initiate a full shutdown of the ISave device along with requesting the membrane air bleed valve to open to release any remaining pressure held in the membrane system.

5. Start-Up Operations

5.1 Overview

The new Atlantic Sea control system has an extremely complicated and comprehensive automatic start up control program designed to start up and monitor all aspects of the water maker system to ensure correct operation. Effective energy recovery requires this automatic start-up control program and as such there are no ways to start the system manually. The controller requires that all of the systems connected devices, equipment and sensory instruments are 100% functional. If any of these previously mentioned components are not 100% functional automatic start-up will not be permitted and attempts to run the system will result in failure. The cause of the failure will be reported to the user via the user display. Repeated attempts to run the water maker system while faults of this nature are being reported are not recommended.

The automatic start-up program ensures maximum energy recovery and enables complete hands free operation of the water maker unit, the operator simply requests a start up from the water maker and stands by as the water maker takes care of all of the required steps needed to place the water production facility into full operation whilst maximizing energy recovery. If any problems arise during the start-up, the control system will take any actions needed to safely shut-down the system and prevent any damage, it will then alert the operator as to what the difficulty was.


Project:

Doc: Version:



5.2 Automatic Start up Operation

Automatic start-up operation is an integrated feature of to the Atlantic Sea Series of products. It allows for virtually hands free start-up of the system and all associated equipment. This automatic start-up operation can also be carried out remotely via the Modbus communications link (if installed) or via the internet interface.

Ensure that the main circuit breaker located in the top right corner of the control panel is in the ‘ON’ position and that the ‘Power On’ Indicator on the front of the control panel is illuminated.

Ensure that the main circuit breaker located in the top right corner of the power distribution panel is in the ‘ON’ position and that the ‘Power On’ Indicator on the front of the power distribution panel is illuminated.

Ensure that the E-Stop button is not pressed in on either panel. If the E-stop button is illuminated, the button is pressed in, release it by turning the mushroom in a clockwise direction.

Ensure no alarms or faults are currently being indicated. If the alarm light is illuminated or flashing an alarm or performance warning is present, accept or clear these alarms before attempting to proceed.

If the control panel has just been powered up, please wait for the ‘System Auto-Stop’ light to illuminate before attempting to automatically start-up the system. Requests to start-up before this light is illuminated will simply be ignored.

To initiate an automatic start-up of the system simply press the ‘Auto-Start’ button on the control panel door or navigate to the ‘System Operation’ screen (See Menu Navigation). Once the screen has been accessed, press the ‘Start System’ button.


Project:

Doc: Version:



Immediately after the ‘Auto-Start’ button is pressed, the green indicator light embedded in the button will begin to flash rapidly, at this moment the system is performing system pre-checks, if a problem is detected the system will abort the automatic start-up routine and display a system fault notification screen detailing the problem (See System Critical Error Messages), as shown below:


The operator must correct the detected problem before re-attempting automatic operation.

If no pre-check errors are detected the control system will begin a 10 second count-down. During the count-down the system will beep intermittently and display a warning screen as shown on the next page, if the user wishes to abort the start-up they may do so by either pressing the ‘Auto-Stop’ button, Emergency Stop’ button or by pressing the abort start-up button displayed on the system start-up countdown timer screen as illustrated on the next page:


Project:

Doc: Version:



Once the 10 second count-down has been completed the control system will begin placing system automated valves into the required position for system start up. This process can take up to 2 minutes and during this time there will be no pump activity. This is normal, it may also be possible to hear some slight hissing sounds and sounds associated with the movement of water and air in water, this is also normal, once correct valve positions have been confirmed the control system will begin to ramp up booster pump speed to achieve the desired high pressure pump inlet pressures, during this ramping procedurethe booster pump operator light will illuminate indicating that the booster pump is running, it may also be possible to hear a slight oscillation of pump speed as the system PID control begins to compensate for system process delays.

The control system constantly performs system checks while ramping the booster pump, target pressures within the system pipe work are expected, if system pressures fail to reach expected levels the system will abort the automatic operation routine the booster pump will be decelerated back to a stopped condition and the controller will display a system fault notification screen detailing the problem (See System Critical Error Messages), as shown on the next page:


Project:

Doc: Version:





Once correct booster pump output pressures have been achieved the control system will enter into a paused state while waiting for any air trapped within the system pipe work to be vented via the air bleed valve, during the paused state the control system will also assess the condition of the system pre-filtration stage. If any system pre-filtration stage is found to be 50% dirty or higher the control system will issue a warning, this warning simply states that the water maker is being started with dirty filters and as a result will require a maintenance visit sooner than normal, this warning screen gives you the option of aborting the automatic start-up operation so filters can be changed or backwashed; if the operator chooses to ignore this message the control system will assume normal start-up operation is desired and will continue with the start-up process after the air purging delay. An example of the dirty filter warning screen can be seen on the next page:


Project:

Doc: Version:



The operator can choose to view this screen during the pre-programmed delay or he can simply press on the button labeled ‘IGNORE’ to return to the previously viewed screen, if the operator does choose to stop the system at this point to clean or backwash filters as recommended the system can be stopped by either pressing the ‘Auto-Stop’ button on the control panel front door or by pressing on the button labeled ‘STOP SYSTEM’ on the warning screen shown above. If the media filter system is the cause of this warning screen the operator can choose to backwash the filter directly from this screen by pressing the backwash button.

If pre-filtration stage checks return normal results this warning screen is not displayedand after the pre-set air purging time has expired the control system will continue with the next stage of the system start up.

During the next phase of the start-up sequence the control system will begin spinning up the ISave device, this spin up procedure is done in several steps, during the entire spin up procedure system process pipe work pressure and flows are closely monitored, if any process variable strays beyond design limits the system will abort the automatic operation routine and as quickly as possible return the water maker back to a fully stopped state; once this rapid shutdown has been completed the controller will display a system fault notification screen detailing the problem (See System Critical Error Messages), as shown on the next page:


Project:

Doc: Version:





The ISave device will begin the spin up procedure by gradually accelerating up to a pre-set speed. During this acceleration the membrane air bleed valve will remain open; however once the ISave device has accelerated past a pre-set speed this valve will be closed. Upon receiving confirmation that the air vent valve has fully closed the ISave will continue to accelerate up to the requested speed as configured in the stage 1 start-up program setting area. Once this speed has been achieved the control system will begin a period of over flushing and air bleeding, this stage lasts for approximately 1 minute. During this time the ISave runs whilst being flooded by feed water from the booster pump, this over flushing purges residual air from the high pressure piping system. Once this over flushing period has ended the ISave device is accelerated up to the normal operating speed as defined in the stage 2 start-up program setting area, once this speed is reached the control system begins monitoring the ISave flow rates.

Now that the ISave device has been fully started the control system can begin the next stage of the automatic start-up procedure, during this phase the High Pressure pump system is slowly accelerated up


Project:

Doc: Version:



to operational speed, as the high pressure pump accelerates the system membrane pressure will begin to rise until production of permeate water begins, during this process the automatic pressure control system within the controller is activated. Once the High Pressure pump has reached full operation speed the control system enters the final state of automatic start-up.

During the final stage of automatic start-up the control system begins to decelerate the booster pump until over flushing is reduced to approximately 10%, If at any time during the automatic start-up procedure a significant problem is detected the control system will begin a rapid automatic shutdown of the unit, once the shutdown has been completedthe controller will display a system fault notification screen detailing the problem (See System Critical Error Messages), as shown below:




Project:

Doc: Version:



6. Automatic Shutdown Operation

At any time in the automatic start up process the system can be shut down by pressing the ‘Auto-Stop’ button, pressing this button results in a controlled shutdown of the system. This controlled shut down can take up to 15 minutes to complete depending on where the system was in its automatic start up routine at the time the ‘Auto-Stop’ button was pressed.

Once pressed the ‘Auto-Stop’ button will begin to flash. This response is to inform you a system shutdown is now in progress. Once the system shut down is completed the ‘System Auto Stop’ light will remain steadily illuminated.

If a system fault is detected during shutdown the controller will display a system fault notification screen detailing the problem (See System Critical Error Messages), as shown below:




Project:

Doc: Version:



7. Emergency Shutdown Operation:

To shut down the system in an emergency press the E-Stop button, pressing this button cause all rotating equipment to cease immediately.Once the E-Stop is released the system will move any activated valves to their home position (if applicable), the ‘Auto-Stop’ button will remain steadily illuminated once this action is completed.

The controller will also display a system fault notification screen detailing that the E-Stop button was activated during operation (See System Critical Error Messages), as shown below:


The operator must release the E-Stop button and accept this warning before re-attempting automatic operation.

8. System Critical Error Messages

The AtlanticSea control system contains four message centers, all of which are intended to provide as much information to the operator as possible. The main of the four message centers is the critical error message center.

During operation if a system failure occurs which could result in the unsafe operation of the water maker, the fault is deemed as a ‘Critical Error’. These types or faults cause an immediate shutdown of the water maker and all associated equipment. The critical error message center is the information window used by the operator to examine system faults of this nature. Typically when these faults occur they are preceded by a ‘System Warning’ screen as shown below:


When a system fault is detected the system fault light remains steadily illuminated, andthe general alarm contact also changes state until the fault is cleared by the operator,this can be done by pressing the ‘Accept & Clear Alarm Message’button on the touch screen or by pressing and holding the ‘Auto-Stop’ button for 2 seconds.

22

F:022 Booster Pump Output Failed To Reach Target

The system attempted to start-up automatically but the booster pump was unable to reach the desired target output pressure within the allowed time. This could be due to severely blocked pre-filtration or some other type of pressure loss either within the system or within the booster pump itself. If no pressure losses can be found it is recommended to disassemble the booster pump stacks to see if damage has occurred.

23 F:023 ISave Brine Pressure Is Below Minimum Range

The system was running or starting up when the ISave brine line pressure dropped below minimum specifications. This can be caused by a defective booster pump, severely blocked pre-filtration, or by the ISave back pressure regulator being set incorrectly. If the ISave BPR has not been adjusted begin checking for sources of booster pump pressure loss

24 F:024 ISave Brine Pressure Is Above Maximum Range

The system was running or starting up when the ISave brine line pressure exceeded maximum specifications. This can be caused by the ISave back pressure regulator being set incorrectly. If the ISave BPR has not been adjusted begin checking for blockages in the ISave brine line

25 F:025 HP Pump Inlet Pressure Is Below Minimum Range

The system was running or starting up when the HP Pump inlet pressure dropped below minimum specifications. This can be caused by a defective booster pump, severely blocked pre-filtration.

26 F:026 HP Pump Inlet Pressure Is Above Maximum Range

The system was running or starting up when the HP Pump inlet pressure exceeded maximum specifications. This can be caused by a rapid increase in system inlet pressure. Check system inlet pressures and any associated regulating equipment

F:027 System Membrane Pressure High Despite Automatic Production Control

The system was running or starting up when membrane pressures exceeded maximum. The control system then activated the automatic pressure control program to correct this issue, but after reducing HP Pump speeds to minimum the system membrane pressure still exceeded maximum and could not be rectified. As a result a rapid shutdown was initiated.

28

F:028 CH4-CH1 Differential Sum Above Maximum Set Value (BF-1004 Is Closed)

The system was running or starting up when the differential pressure across a section of system pipework exceeded the detection threshold. This indicates to the controller that a manual valve in this section of pipework has been closed. The suspected valve is listing in the fault message. Ensure the valve is fully open before attempting to run the system again

29

F:029 CH1-CH13 Differential Sum Above Maximum Set Value (BF-1002 Is Closed)

The system was running or starting up when the differential pressure across a section of system pipework exceeded the detection threshold. This indicates to the controller that a manual valve in this section of pipework has been closed. The suspected valve is listing in the fault message. Ensure the valve is fully open before attempting to run the system again

30

F:030 HP Pump Low Pressure Switch Detected HP Pump Inlet Pressure Loss

Inlet pressure to the High Pressure pump dropped to extremely low levels before transducers were able to detect. This initiated a rapid shutdown of the unit but possible cavitation of the HP Pumps may off occurred. It is advised to find the loss of booster pressure (check water source) before re-starting the system. If re-starting can take place the pump should be checked for higher operating temperatures. The pump swash face should never exceed the temperature of the system water feed.

31

F:031 HP Pump High Pressure Switch Detected HP Pump Outlet Pressure High

The system High Pressure pump outlet pressure exceeded the maximum allowable for system containment before the automatic pressure reduction program could rectify the problem. Such a rapid increase in system pressure is unusual. Any cause for this increase in pressure should be fully investigated before re-attempting auto-start operations.

32

F:032 Membrane High Pressure Switch Detected HP Pump Outlet Pressure High

The system membrane outlet pressure exceeded the maximum allowable for system containment before the automatic pressure reduction program could rectify the problem. Such a rapid increase in system pressure is unusual. Any cause for this increase in pressure should be fully investigated before re-attempting auto-start operations.

9. System Performance Messages

The Atlantic Sea control system contains four message centers, all of which are intended to provide as much information to the operator as possible. The most commonly displayed of the four message centers is the performance message center.

During operation, if a system fault which results in the water maker not operating at peak efficiency is detected, the fault is deemed as a ‘Non Critical Error’. These types of faults do not require an immediate shutdown of the water maker. While safe to do so the water maker will continue to run and prompt the operator that attention is required by logging the fault in the performance message center. The performance message center is the information window used by the operator to examine system faults of this nature. Typically when these faults occur they are preceded by a ‘Performance Warning’ screen as shown below:

Pressing ‘Highlight AlertMessage’ will highlight the first alarm item. Pressing ‘Scroll Up’ will scroll up through the alarm list Pressing ‘Scroll Down’ will scroll down through the alarm list Pressing ‘Accept This Notification’ will clear the listed alarm notifications and return you to the previous screen. Pressing ‘Back’ will exit the alarm list. Please note the ‘Back’ button is only active if no faults or errors are currently displayed, if errors or faults are displayed, press ‘Accept’ to exit this screen. Pressing ‘More Information On This Notice’will call up the on-line interactive help files associated with this alarm condition, these on-line help files will assist you in diagnosing and solving the problem (if installed)

When a system performance fault is detected the system fault indicator will blink at 0.5 second intervals, the general alarm contact will not change state in these situations. The system fault indicator will continue to blink until the fault is accepted by the operator; this can be done by pressing the ‘Accept This Notification’button in the performance message center. Once a fault has been accepted the system fault indicator will stop blinking, but a log of the fault is kept within the performance message center. This list of potential problems can be viewed at any time by manually navigating back to the performance message center (See Menu Navigation)

14. Manual Actuation of System Valves.

Manual actuation of system valves maybe required in emergency situations. Actuating these valves can be carried out in the following manner:

14.1 Actuating the Membrane Pressure Relief Motorized Valve

To manually actuate this valve the operator must first remove power from the valve actuator motor. This is done by locating the red wire within the controller cabinet. This wire will be found in the following location: Locate TB4 in the lower middle section of the controller enclosure (See figure 1.1)

Figure 1.1

Once TB4 is located, identify terminal number 7, this terminal will have a red wire connected to it, using a small flat bladed screw driver (maximum width 3mm) open the spring clamp terminal by pushing the flat bladed screw driver fully into the terminal release terminal and remove the red wire (See figure 1.2)

Figure 1.2

15. Fresh Water Flushing

Each time a running pump is stopped using the ‘Auto-Stop’ button the fresh water flush system will automatically be activated. Once all running pumps have been stopped the fresh water flush valve will open allowing fresh water into the system. The valve will remain open for 10 minutes to allow fresh water to completely fill the water maker pipe work and membrane vessels, during this time the fresh water flush indicator on the control panel door will remain steadily illuminated.

After the 10 minute fresh water flush cycle has ended, the valve will close and the fresh water flush indicator light on the panel door will extinguish. The control system will now enter ‘Sleep Mode’, while in this state the fresh water flush indicator light will illuminate for 1 second each hour. This brief flashing is indicating that the fresh water flush mode is still active but currently waiting for the next fresh water flush cycle to begin.

7 Days after the initial fresh water flush cycle completed, a secondary fresh water flush cycle will begin; the valve will re-open for 10 minutes allowing fresh water to flood the system once again. While the valve is open the fresh water flush indicator light on the panel door will remain steadily illuminated. After the 10 minute cycle has elapsed the control system will return to ‘Sleep Mode’.

This cycle will continue indefinitely, unless a system pump is started by the operator, or the operator cancels the fresh water flush sequence by pressing and holding the “Auto-Stop’ button for 2 seconds.

When the fresh water flush system is flushing; the control system examines the available fresh water pressure, if pressures are detected as being below the system set-point a performance warning notification is raised by the control system as shown below:

17.2 Auto MMF Sequence Delay Time (Minutes) [Range = > 1]

This value stated in minutes determines how long the system will wait before initiating an automatic backwash cycle once the pre-determined differential pressure across the media filter housing has been detected. Once this time expires the controller will shutdown the water maker and prepare the system for an automatic backwash cycle.

Typical values entered here are 5 minutes in all applications

17.3 Auto MMF Backwashing Time (Minutes) [Range = > 1]

This value stated in minutes determines how long the system willbackwash the multi-media filter for. Once this time has expired the controller will shutdown the water maker booster pump and prepare the system for rinsing.


17.4 Auto MMF Rinsing Time (Minutes) [Range = > 1]

This value stated in minutes determines how long the system will rinse the multi-media filter for. Once this time has expired the controller will shutdown the water maker booster pump and prepare the system for normal operation.

17.7 Activating the backwashcycle manually while operating the system in automatic mode

If your system is in operation the control system will automatically initiate multi-media backwashing cycles when needed, however you can still initiate these backwash cycles manually if you choose to do so. Please note that if you manually initiate a backwash cycle during automatic operation the system will see this as a manual intervention; hence once the backwash cycle has been completed the system will remain shut-down and will not automatically re-start and re-enter production mode by itself.

To manually initiate a backwashing cycle during automatic modepress panel button #11 ‘Back Wash Status’ (illustrated on page 7), once you press this button the controller touch screen will display the following screen:

If you wish to cancel your request to initiate the backwashing cycle at this time press the ‘No’ button, doing so will cancel the above screen and automatically schedule a backwashing cycle for the next time the system is shutdown normally, if you do not wish to initiate a backwash or schedule a backwash for later simply ignore this screen, after 60 seconds it will self-cancel. If you wish to initiate the backwashing procedure press the ‘Yes’ button on the touch screen or press panel button #11 ‘Back Wash Status’ again.

Once you press either panel button #11 or the ‘Yes’ button on the touch screen the system will begin an automatic shutdown of the water maker and enter the automatic backwashing sequence.

17.8 Automatic activation of the backwashcycle

If your system is in operation the control system will automatically initiate multi-media backwashing cycles when needed, when the control system initiates a backwashing cycle automatically it begins by shutting down the water maker, once the backwashing cycle has completed the control system will automatically re-start the water maker and place it back into production. The control system initiates an automatic backwashing cycle when it detects a high differential pressure across the multi-media filter assembly, before initiating the automatic shutdown procedure the control system will alert the system operator by displaying the following screen:

Once the indicated time has elapsed the system will begin an automatic shutdown of the water maker and enter the automatic backwashing sequence. Once the backwashing sequence has completed the system will re-start and re-enter production mode automatically.

If you wish to skip the countdown time and initiate a backwash cycle manually press the panel button #11 ‘Back Wash Status’ twice, pressing this button in this manner will abort the 5 minute count down and initiate the backwashing cycle immediately. Please note, as a manual intervention was detected the system will no longer automatically re-start and re-enter production mode, instead it will simply remain in shutdown mode once the backwashing cycle has completed.
