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 high pressure switch and connections to
TB4-24 and TB4-25.
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).
