ADDITIONAL CAUSE/REMEDY
Compressor is running with more than
10% RLA and control is trying to shut it
down. Throw power off to compressor if
unable to stop. Determine cause before
repowering.
Determine cause. If pumping refrigerant
out of chiller, stop operation and go over
pumpout procedures.
Starter and run and start contacts are
energized while control tried to shut
down. Disconnect power to starter.
Check wiring from PSIO to SMM. Check
SMM module troubleshooting procedures.
Starter run and start contacts energized
while chiller was off. Disconnect power.
The condenser pressure transducer is
reading a pressure that could freeze the
water in the condenser tubes. Check for
condenser refrigerant leaks, bad trans-
ducers, or transferred refrigerant. Place
the unit in Pumpdown mode to eliminate
ALARM if vessel is evacuated.
