PRIMARY CAUSE
Check sensor resistance or voltage drop.
Check for proper wiring.
Check sensor resistance or voltage drop.
Check for proper wiring.
Check for partially or closed shut-off valves.
Check oil filter.
Check oil pump and power supply.
Check oil level.
Check for foaming oil at start-up.
Check transducer wiring and accuracy.
Power loss has been detected in any phase.
Chiller automatically restarting.
A drop in line voltage has been detected within
2 voltage cycles.
Chiller automatically restarting if Auto Restart is
enabled in OPTIONS screen.
Check phase to phase and phase to ground line
power.
Check phase to phase and phase to ground line
power.
VFD Module has detected a hardware fault due
to electrical noise, power loss or software and
has reset. Chiller automatically restarting.
Check for power loss and sources of electro-
magnetic interference.
Check 24 vac control power supply to ICVC.
Check sensor resistance or voltage drop.
Check for proper wiring.
Check for proper inlet guide vane and optional
diffuser actuator operation.
Check for proper condenser flow and
temperature.
Check for high lift or low load.
Check for fouled tubes or noncondensables in
the chiller.
Check sensor resistance or voltage drop.
Check for proper wiring.
Check for partially closed service valves.
Check oil cooler TXV.
Check oil level and oil temperature.
Check sensor wiring and accuracy.
Check condenser flow and water temperature.
Check for fouled tubes.
This alarm is not caused by the High Pressure
Switch.
Chiller load is too low to keep compressor on
line and there has been more than 5 starts in
4 hours.
Increase chiller load, adjust hot gas bypass,
increase RECYCLE RESTART DELTA T from
SETUP1 Screen.
Illegal chiller address configuration in Lead/Lag
screen. Both chillers require a different address.
The condenser pressure transducer is reading a
pressure that could freeze the condenser tubes.
Check for condenser refrigerant leaks.
Check fluid temperature.
Check sensor wiring and accuracy.
Place the chiller in PUMPDOWN mode if the
vessel is evacuated.
Check sensor resistance or voltage drop.
Check for proper wiring to CCM connector J4.
Check sensor resistance or voltage drop.
Check for proper wiring to CCM connector J5.
Check sensor resistance or voltage drop.
Check for proper wiring to CCM connector J5.
Check sensor resistance or voltage drop.
Check for proper wiring to CCM connector J4.
Check Spare Temp #1 Limit in SETUP1 screen.
