L. CHILLER PROTECT LIMIT FAULTS (cont)
Excessive numbers of the same fault can lead to severe chiller
damage. Seek service expertise.
PRIMARY MESSAGE SECONDARY MESSAGE
PROTECTIVE LIMIT TRANSDUCER VOLTAGE FAULT
PROTECTIVE LIMIT LOW GEAR OIL PRESSURE
PROTECTIVE LIMIT HIGH GEAR OIL TEMP
PROTECTIVE LIMIT CCN OVERRIDE STOP
*[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. [OPEN] indicates that an input circuit is open.

ALARM MESSAGE/PRIMARY CAUSE
High Amps at Recycle: Check guide vane
drive.
Sensor Fault: Check leaving condenser
water sensor.
Sensor Fault: Check entering condenser
water sensor.
Low Oil Pressure Alert: Check oil
V P Power Loss: Check voltage
supply.
V P [VALUE] exceeded limit of [LIMIT]*.
Check voltage supply.
V P [VALUE] exceeded limit of [LIMIT]*.
Check voltage supply.
CMPD [VALUE] exceeded limit of
[LIMIT]*. Check discharge
temperature.
MTRB [VALUE] exceeded limit of
[LIMIT]*. Check thrust bearing
temperature.
CRP High Condenser Pressure [LIMIT]*.
Pump energized to reduce pressure.
Excessive recycle starts.
GEAROILP [VALUE] exceeded imit of
[LIMIT]*. Check gear oil pump filter.
GEAOILT [VALUE] exceeded limit of
[LIMIT]*. Check gear oil cooler filter.

ADDITIONAL CAUSE/REMEDY
Check transformer power (5 vdc) supply to
transducers. Power must be 4.5 to 5.5 vdc.
Check for closed oil supply valves. Check oil fil-
ter. Check transducer accuracy.
Check for cooler water flow. Check sensor for
accuracy.
Machine received a command from the net-
work to stop overriding local operating mode.
ADDITIONAL CAUSE/REMEDY
Check that guide vanes are closing. Check
motor amps correction calibration is cor-
rect. 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 excessive
compressor starts occurring.
Discharge temperature exceeded the alert
threshold. Check entering condenser water
temperature.
Thrust bearing temperature exceeded the
alert threshold. Check for closed valves, im-
proper oil level or temperatures.
Check ambient conditions. Check con-
denser 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, ad-
just hot gas bypass, increase RECYCLE RE-
START DELTA T from SERVICE1 screen.
Check for closed oil supply valves. Check
oil filter. Check transducer accuracy.
Check for cooler water flow. Check sensor
for accuracy.
