ADDITIONAL CAUSE/REMEDY
Check that guide vanes are closing.
Check motor amps correction cali-
bration is correct. Check actuator for
proper operation.
Check sensor. See sensor test
procedure.
Check oil filter. Check for improper
oil level or temperature.
Check power supply if there are ex-
cessive compressor starts occurring.
Discharge temperature exceeded
the alert threshold. Check entering
condenser water temperature.
Thrust bearing temperature ex-
ceeded the alert threshold. Check
for closed valves, improper oil level
or temperatures.
Check ambient conditions. Check
condenser pressure for accuracy.
The chiller load is too small to keep
the chiller on line and there have
been more than 5 restarts in 4
hours. Increase chiller load, adjust
hot gas bypass, increase RECYCLE
RESTART DELTA T.
ADDITIONAL CAUSE/REMEDY
Check alert temperature set points
on Equipment Service, SERVICE2
LID table. Check sensor for accu-
racy if reading is not accurate.
