* [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.

Recycle Alert
High Amps at Shut-
down
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
sensor.
Check sensor. See sensor test procedure.
Sensor Fault
Alert
Entering Cond Water
Temp
Sensor Fault: Check
entering condenser
water sensor.
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 dis-
charge temperature.
Discharge temperature exceeded the alert
threshold. Check entering condenser water
temperature.
Sensor Alert
High Bearing Tempera-
ture
MTRB [VALUE]
exceeded limit of
[LIMIT*]. Check thrust
bearing temperature.
Thrust bearing temperature exceeded the
alert threshold. Check for closed valves,
improper 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
machine load, adjust hot gas bypass,
increase RECYCLE RESTART DELTA T.
