C. IN RECYCLE SHUTDOWN
PRIMARY MESSAGE SECONDARY MESSAGE PROBABLE CAUSE/REMEDY
RECYCLE RESTART PENDING OCCUPIED MODE
Unit in recycle mode, chilled water temperature is not
high enough to start.
RECYCLE RESTART PENDING REMOTE CONTACT CLOSED
Unit in recycle mode, chilled water temperature is not
high enough to start.
RECYCLE RESTART PENDING START COMMAND IN EFFECT
Chiller START/STOP on Status01 manually forced to
start, chilled water temperature is not high enough to
start.
RECYCLE RESTART PENDING ICE BUILD MODE
Chiller in ICE BUILD mode. Chilled Water/Brine Tem-
perature is satisfied for Ice Build Setpoint temperature.
D. PRE-START ALERTS: These alerts only delay start-up. When alert is corrected, the start-up will continue. No reset is necessary.
PRIMARY MESSAGE SECONDARY MESSAGE ALARM MESSAGE/PRIMARY CAUSE ADDITIONAL CAUSE/REMEDY
PRESTART ALERT STARTS LIMIT EXCEEDED
STARTS EXCESSIVE Compressor
Starts (8 in 12 hours)
Depress the RESET softkey if addi-
tional start is required. Reassess
start-up requirements.
PRESTART ALERT HIGH MOTOR TEMPERATURE
MTRW [VALUE]* exceeded limit of
[LIMIT]*. Check motor temperature.
Check motor cooling line for proper
operation. Check for excessive
starts within a short time span.
PRESTART ALERT HIGH BEARING TEMPERATURE
MTRB [VALUE]* exceeded limit of
[LIMIT]*. Check thrust bearing
temperature.
Check oil heater for proper opera-
tion, check for low oil level, partially
closed oil supply valves, etc. Check
sensor accuracy.
PRESTART ALERT HIGH DISCHARGE TEMP
CMPD [VALUE]* exceeded limit of
[LIMIT]*. Check discharge temperature.
Check sensor accuracy. Allow dis-
charge temperature to cool. Check
for excessive starts.
PRESTART ALERT LOW REFRIGERANT TEMP
ERT [VALUE]* exceeded limit of
[LIMIT]*. Check refrigerant temperature.
Check transducer accuracy. Check
for low chilled water/brine supply
temperature.
PRESTART ALERT LOW OIL TEMPERATURE
OILT [VALUE]* exceeded limit of
[LIMIT]*. Check oil temperature. Check oil heater power, oil heater
relay. Check oil level.
PRESTART ALERT LOW LINE VOLTAGE
V P [VALUE]* exceeded limit of
[LIMIT]*. Check voltage suppy.
Check voltage supply. Check volt-
age transformers. Consult power
utility if voltage is low. Adjust voltage
potentiometer in starter for SMM
voltage input.
PRESTART ALERT HIGH LINE VOLTAGE
V P [VALUE]* exceeded limit of
[LIMIT]*. Check voltage supply.
Check voltage supply. Check volt-
age transformers. Consult power
utility if voltage is low. Adjust voltage
potentiometer in starter for SMM
voltage input.
PRESTART ALERT HIGH CONDENSER PRESSURE
CRP [VALUE]* exceeded limit of
[LIMIT]*. Check condenser water and
transducer. Check for high condenser water
temperature. Check transducer
accuracy.
*[LIMIT] is shown on the LID as temperature, pressure, voltage, etc., predefined or selected by the operator as an override or an alert. [VALUE] is
the actual temperature, pressure, voltage, etc., at which the control tripped.
