Table 9 — LID Primary and Secondary Messages and Custom Alarm/Alert Messages
with Troubleshooting Guides (cont)
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 calibra-
tion is correct. Check actuator for proper
operation.
SENSOR FAULT ALERT
LEAVING COND WATER
TEMP
Sensor Fault: Check leaving condenser wa-
ter sensor.
Check sensor. See sensor test
procedure.
SENSOR FAULT ALERT
ENTERING COND WATER
TEMP
Sensor Fault: Check entering condenser wa-
ter sensor.
LOW OIL PRESSURE
ALERT
CHECK OIL FILTER
Low Oil Pressure Alert: Check oil pressure. 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 ex-
cessive 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 con-
denser water temperature, reduce en-
tering condenser water temperature, if
possible.
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, improper oil level or tempera-
tures.
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. Check
pump operation in Control Test table.
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.
*[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

Sensor Fault: Check common CHWS
sensor.
Check alert temperature set points on Equip-
ment Service, SERVICE2 LID table.
Check sensor for accuracy if reading is not
accurate.
SPARE SENSOR ALERT
COMMON CHWR SENSOR
Sensor Fault: Check common CHWR
sensor.
SPARE SENSOR ALERT
REMOTE RESET SENSOR
Sensor Fault: Check remote reset tem-
perature sensor.
