CAUSE/REMEDY
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).
COMPRESSOR
100% SPEED in VFD CONF
screen must be set between 45-52 Hz [{ LINE

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.
*[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.
