L. MACHINE ALERTS
PRIMARY MESSAGE SECONDARY MESSAGE ALARM MESSAGE/PRIMARY CAUSE ADDITIONAL CAUSE/REMEDY
RECYCLE ALERT HIGH AMPS AT SHUTDOWN High Amps at Recycle: Check guide vane drive. Check that guide vanes are closing. Check
motor amps correction calibration is cor-
rect. Check actuator for proper operation.
SENSOR FAULT ALERT LEAVING COND WATER
TEMP
Sensor Fault: Check leaving condenser water sen-
sor.
Check sensor. See sensor test
procedure.
SENSOR FAULT ALERT ENTERING COND WATER
TEMP
Sensor Fault: Check entering condenser water sen-
sor.
LOW OIL PRESSURE
ALERT
CHECK OIL FILTER Low Oil Pressure Alert: Check oil Check oil filter. Check for improper oil level
or temperature.
AUTORESTART PENDING POWER LOSS V P Power Loss: Check voltage
supply.
Check power supply if there are excessive
compressor starts occurring.
AUTORESTART PENDING LOW LINE VOLTAGE V P [VALUE] exceeded limit of [LIMIT]*. Check
voltage supply.
AUTORESTART PENDING HIGH LINE VOLTAGE V P [VALUE] exceeded limit of [LIMIT]*. Check
voltage supply.
SENSOR ALERT HIGH DISCHARGE TEMP CMPD [VALUE] exceeded limit of [LIMIT]*. Check
discharge temperature.
Discharge temperature exceeded the alert
threshold. Check entering condenser water
temperature.
SENSOR ALERT HIGH BEARING
TEMPERATURE
MTRB [VALUE] exceeded limit of [LIMIT]*. Check
thrust bearing temperature.
Thrust bearing temperature exceeded the
alert threshold. Check for closed valves, im-
proper oil level or temperatures.
CONDENSER PRESSURE
ALERT
PUMP RELAY ENERGIZED CRP High Condenser Pressure [LIMIT]*.
Pump energized to reduce pressure.
Check ambient conditions. Check con-
denser pressure for accuracy.
RECYCLE ALERT EXCESSIVE RECYCLE
STARTS
Excessive recycle starts. The machine load is too small to keep the
machine on line and there have been more
than 5 restarts in 4 hours. Increase ma-
chine load, adjust hot gas bypass, increase
RECYCLE RESTART DELTA 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
PRIMARY MESSAGE SECONDARY MESSAGE ALARM MESSAGE/PRIMARY CAUSE ADDITIONAL CAUSE/REMEDY

sensor.
SPARE SENSOR ALERT REMOTE RESET SENSOR Sensor Fault: Check remote reset tempera-
ture sensor.
