L. CHILLER ALERTS
PRIMARYMESSAGE SECONDARYMESSAGE ALARM MESSAGE/PRIMARYCAUSE ADDITIONAL CAUSE/REMEDY
RECYCLEALERT HIGHAMPS AT SHUTDOWN HighAmps at Recycle: Check guide vane
drive.
Check that guide vanes are closing.
Check motor amps correction cali-
bration is correct. Check actuator for
proper operation.
SENSOR FAULTALERT LEAVINGCOND WATER
TEMP Sensor Fault: Check leaving condenser
water sensor. Check sensor.See sensor test
procedure.
SENSOR FAULTALERT ENTERING COND WATER
TEMP Sensor Fault: Check entering condenser
water sensor.
LOW OIL PRESSURE
ALERT CHECK OILFILTER Low Oil Pressure Alert: Check oil Checkoil filter. Check for improper
oil level or temperature.
AUTORESTARTPENDING POWER LOSS V PPower Loss: Check voltage supply.
Check power supply if there are ex-
cessive compressor starts occurring.
AUTORESTARTPENDING LOW LINE VOLTAGE V P[VALUE]* exceeded limit of
[LIMIT].* Check voltage supply.
AUTORESTARTPENDING HIGH LINE VOLTAGE V P[VALUE]* exceeded limit of
[LIMIT].* Check voltage supply.
SENSORALERT HIGH DISCHARGE TEMP CMPD [VALUE]* exceeded limit of
[LIMIT].* Check discharge temperature.
Discharge temperature exceeded
the alert threshold. Check entering
condenser water temperature.
SENSORALERT HIGH BEARING
TEMPERATURE
MTRB [VALUE]*exceeded limit of
[LIMIT]*. Check thrust bearing
temperature.
Thrust bearing temperature ex-
ceeded the alert threshold. Check
for closed valves, improper oil level
or temperatures.
CONDENSER PRESSURE
ALERT PUMP RELAYENERGIZED CRPHigh Condenser Pressure
[LIMIT]*. Pump energized to reduce
pressure.
Check ambient conditions. Check
condenser pressure for accuracy.
RECYCLEALERT EXCESSIVE RECYCLE
STARTS Excessiverecycle starts.
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
RESTARTDELTA T.
*[LIMIT]is shown on the LID 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 temperature, pressure, voltage, etc., at which the control tripped.
M. SPARE SENSOR ALERT MESSAGES
PRIMARYMESSAGE SECONDARYMESSAGE ALARMMESSAGE/PRIMARY CAUSE ADDITIONALCAUSE/REMEDY
