*[LIMIT] is shown on the ICVC as the temperature, pressure, voltage, etc., set point predefined or selected by the operator as an override, alert, or
alarm condition. [VALUE] is the actual pressure, temperature, voltage, etc., at which the control tripped.
NOTE: ICVC Alarms 212-226 are declared as a result of VFD Faults.

PRIMARY CAUSE
Malfunction within VFD Power Module.
Call Carrier Service.
Malfunction within VFD Power Module.
Call Carrier Service.
Check main circuit breaker for trip. Increase
Current % Imbalance in VFD_CONF screen.
Check that inlet guide vanes are fully closed at
start-up.
Check Motor Rated Load Amps in VFD_CONF
screen. Reduce unit pressure if possible.
VFD Circuit Board malfunction.
Call Carrier Service.
Verify phase to phase and phase to ground line
voltage. Monitor AC line for high transient volt-
age conditions. VFD Circuit Board malfunction.
Call Carrier Service.
See VFD Fault Code description and corrective
action.
Check Compressor Discharge High Pressure
switch wiring and accuracy.
Check for high condenser water temperatures,
low water flow, fouled tubes.
Check for division plate/gasket bypass.
Check for noncondensables in refrigerant.
Check Motor Rated Load Amps in VFD_CONF
screen. Percent Load Current > 110%.
Check Motor Rated Load Amps setting.
Check phase to phase and phase to ground
power distribution bus voltage.
Check Line Current % Imbalance in VFD_CONF
screen. Consult power company.
Temporary loss of voltage. Disable Single Cycle
Dropout in VFD_CONF screen.
Check phase to phase and phase to ground dis-
tribution bus voltage. Consult power company.
Check phase to phase and phase to ground dis-
tribution bus voltage. Consult power company.
Temporary loss of VFD control voltage. Check
VFD control power breaker, transformer and
fuses.
Check phase to phase and phase to ground dis-
tribution bus voltage.
Check VFD fuses.
Check 24 vac power supply to ICVC.
Consult power company.
Verify phase-to-phase and phase-to-ground line
voltage. VFD Circuit Board malfunction.
Call Carrier Service.
Check phase-to-phase and phase-to-ground
distribution bus voltage. Increase Line Voltage
% Imbalance in VFD_CONF screen.
Any phase current > 106% Rated Load Amps.
Can result from significant load side current
imbalance when running at full load.
Check entering condenser water temperature
and water flow rate.
Check Motor Rated Load Amps in VFD_CONF
screen.
Check that VFD refrigerant isolation valves are
open.
Check VFD refrigerant cooling solenoid and
refrigerant strainer.
Check for proper VFD cooling fan operation and
blockage.
Check that VFD refrigerant isolation valves are
open.
Check VFD refrigerant cooling solenoid and
refrigerant strainer.
Check for proper VFD cooling fan operation and
blockage.
