Fault Indications
PURGE FAULT
Indicates
maximum allowed pumpout time during any 24 sliding window hour period has been
exceeded
Displayed:
PURGE FAULT
When purge pumpout time exceeds pre-set maximum allowed pumpout time, (see SETTINGS
operating parameters starting on page 26) the purge will Lock -Out on “PURGE FAULT”.
DRAIN FAULT
Indicates the purge is "OFF" in a drain fault condition.
Displayed:
DRAIN FAULT
Under certain conditions (such as when the purge is operating wh ile the chiller is OFF),
pressure gradient imbalances may develop which can retard liquid drainage from the purge
tank. A “DRAIN BACK EQUALIZATION CYCLE periodically cycles the purge condensing unit
allowing pressures time to can equalize, and thus allow t he purge tank to drain.
If the drain back equalization cycle fails to correct such pressure gradient imbalances, or if
there are any other problems affecting proper drainage such as a defective drain solenoid
valve, float switch, etc. then a drain fault will occur.
BATTERY FAULT
Indicates purge is "OFF" in a battery fault condition.
Displayed:
BATTERY FAULT
The Microprocessor Controller incorporates a self -charging battery backup that prevents loss
of critical data during power down periods or po wer failure. The battery back-up will maintain
stored data and parameters for approximately 10 days.
When a “BATTERY FAULT” has occurred, all fault parameters settings will revert to their
factory default setting (see page 26). All information stored in the operational data LOGs as
well as clock time will also be lost. Clock time and fault parameter settings will have to be
reset.
