HP pump outlet exceeded
maximum permissible pressure.
System stopped.
During normal operation, in manual and automatic
mode, the system exceeding maximum pressure
allowed. A fault has occurred and the system will
activate an emergency shutdown to protect the water
maker and ship equipment. Re-start the system, if back
pressure regulator initialization completes correctly
and the system re-starts; its highly possible a rapid
change in system pressure occurred for some unknown
external reason and the change was so rapid that the
automatic pressure regulator was not able to adjust
quickly enough to compensate. If this happen during
system commissioning check BPR wiring.

HP pump outlet sensor in by-pass
& brine flow low. Possible
cavitation.
The system was operating with the high-pressure pump
outlet sensor in bypass mode. During operation, the
control system detected that brine flow dropped below
calculated levels. This is a good indication that pump
cavitation was occurring. The system was stopped to
protect the pump from damage. Follow the items listed
in fault description 12 on previous page, to locate the
possible reason for this pump inlet cavitation.
18
BPR initialization fault. BPR is
jammed. Please attempt recovery
in 'Customer Options'.
The control system attempted to initialize the
automatic back pressure regulator assembly, during
this initialization a motor over current was detected.
This indicates the pressure regulator is jammed, follow
the instructions listed in section 15 to attempt to free
up the regulator. If these steps do not release the
regulator removal of the system top cover and manual
intervention with a wrench may be required.
19
System emergency stop requested
in manual. All moving machinery
stopped!
Once the system was running in manual mode the E-
Stop button was pressed. Release the E-stop button
before attempting to run the unit again.
20
Brine flow low during manual
operation. Possible pump
cavitation.
The system was operating with the high-pressure pump
outlet sensor in bypass mode. During operation, the
control system detected that brine flow dropped below
calculated levels. This is a good indication that pump
cavitation was occurring. The system was stopped to
protect the pump from damage. Follow the items listed
in fault description 12 on previous page, to locate the
reason for this pump inlet cavitation.
21
Brine flow low during fresh water
flush. Possible loss of feed supply.
The system was fresh water flushing the unit, but
detected that brine water flow rates are much lower
than expected. This usually indicates a loss of fresh
water supply to the unit. Please check this water supply
to ensure it is not isolated elsewhere in the ship. If fresh
water is present, check correct operation of the fresh
water flush valve.
