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 main-
tained between 45-52 Hz if LINE FREQ=60Hz? is set to
NO(50 Hz). LINE FREQUENCY 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). COMPRESSOR 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 com-
patible.
Call Carrier Service.
VFD Gateway and ICVC software versions are not com-
patible.
Call Carrier Service.
Check for high entering water temperature or low con-
denser water flow.
Check current settings in VFD_CONF screen.
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 SETUP3 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 elec-
trical noise, power loss or software and has reset.
Chiller automatically restarting.
Check for power loss and sources of electromagnetic
interference.
Check 24 vac control power supply to ICVC.
COND HI FLOW ALARM OPT is disabled and CON-
DENSER WATER DELTA P has exceeded configured
limit. Check FLOW DELTA P DISPLAY and COND HI
FLOW DEL P LIMIT in SETUP1 screen. Check optional
condenser water pressure transducer wiring and accu-
racy. Confirm that 5 V reference signal is available
between CCM J3-19 and J3-21 and J3-22 and J3-24.
Check for disconnected, grounded, or shorted wiring. If
pressure transducers are not installed, check for pres-
ence of resistors and jumpers CCM terminals J3-19
through J3-24. See Chiller Controls Schematic if flow
switches are used.
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.
