L. MACHINE ALERTS

PRIMARY MESSAGE SECONDARY MESSAGE ALARM MESSAGE/

PRIMARY CAUSE

ADDITIONAL CAUSE/REMEDY

RECYCLE ALERT HIGH AMPS AT SHUTDOWN* HighAmps at Recycle: Check slide

valve.

Check that slide valve is opening. Check

motor amps correction calibration is

correct.

SENSOR FAULT ALERT LEAVING COND WATER TEMP Sensor Fault: Check leaving con-

denser water sensor.

Check sensor: See sensor test

procedure.

SENSOR FAULT ALERT ENTERING COND WATER TEMP Sensor Fault: Check entering con-

denser water sensor.

DIRTY OIL FILTER

ALERT

HIGH OIL PRESSURE DROP Replace oil ﬁlter. Condenser pressure minus oil ﬁlter pres-

sure alert greater than oil pressure trans-

ducer. Reconﬁgure oil ﬁlter pressure alert

on Service1 or change oil ﬁlter.

AUTORESTART PENDING POWER LOSS V P Power Loss: Check voltage

supply.

Check power supply if there are exces-

sive compressor starts occuring.

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 oil temperature.

Discharge temperature exceeded the alert

threshold. Check entering condenser wa-

ter temperature.

SENSOR ALERT LOW OIL PRESSURE OILPD VALUE exceeded limit of

[LIMIT]†. Low oil pressure alert.

Check that oil pressure transducer and/or

evaporator pressure transducer are not out

of range. Check entering condenser wa-

ter temperature.

CONDENSER PRESSURE

ALERT

PUMP RELAY ENERGIZED CRP High Condenser Pressure,

[VALUE] Pump energized to re-

duce 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. More than 5 restarts have

occurred in 4 hours. Increase machine load,

adjust hot gas bypass, increase RECYCLE

RESTART DELTA T temperature. Do not

start chiller until minimum load is avail-

able.

POTENTIAL FREEZE-UP COND PRESS/TEMP TOO LOW CONDENSER freeze-up

protection.

Check condenser water pump operation.

Refer to Condenser Freeze Protection sec-

tion on page 31.

*Only applicable PSIO Software Version 13 and lower.

†[LIMIT] is shown on the LID as temperature, pressure, voltage, etc., predeﬁned or selected by the operator as an override or an alert.

M. SPARE SENSOR ALERT MESSAGES

PRIMARY MESSAGE SECONDARY MESSAGE ALARM MESSAGE/

PRIMARY CAUSE

ADDITIONAL CAUSE/REMEDY

SPARE SENSOR ALERT COMMON CHWS SENSOR Sensor Fault: Check common

CHWS sensor.

Check alert temperature set points on Equip-

ment Service Service2 LID screen.

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

temperature sensor.
