PRIMARY CAUSE
CCN has signaled the chiller to stop.This fault
must be manually reset from the default screen
of the ICVC.
LINE FREQUENCY in POWER screen must be
maintained between 45-52 Hz if LINE
FREQ=60Hz? is set to NO(50 Hz). LINE FRE-
QUENCY must be maintained between
55-62 Hz if LINE FREQ=60Hz? is set to YES
(60 Hz).
Check 2C AUX/HPR Gate Kill circuit.
COMPRESSOR 100% SPEED in VFD_CONF
screen must be set between 45-52 Hz if LINE
FREQ=60Hz? is set to NO(50 Hz). COMPRES-
SOR 100% SPEED must be set between
55-62 Hz if LINE FREQ=60Hz? is set to YES
(60 Hz).
VFD Gateway and VFD software versions are
not compatible.
Call Carrier Service.
VFD Gateway and ICVC software versions are
not compatible.
Call Carrier Service.
Check for high entering water temperature or
low condenser water flow.
Check current settings in VFD_CONF screen.
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.
