ture 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 additional 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. Check refrigerant filter.
PRESTART ALERT
HIGH BEARING TEMPERATURE
MTRB VALUE exceeded limit of [LIMIT]*. Check
thrust bearing temperature.
Check oil heater for proper operation, check for
low oil level, partially closed oil supply valves,
etc. Check sensor accuracy. Check oil cooler
and valve.
PRESTART ALERT
HIGH DISCHARGE TEMP
CMPD VALUE exceeded limit of [LIMIT]*. Check
discharge temperature.
Check sensor accuracy. Allow discharge tem-
perature to cool. Check for excessive starts. Avoid
entended low load operation.
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. Check oil cooler solenoid.
PRESTART ALERT
LOW LINE VOLTAGE
V
P VALUE exceeded limit of [LIMIT]*. Check
voltage suppy.
Check voltage supply. Check voltage transform-
ers. Consult power utility if voltage is low. Ad-
just 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 voltage transform-
ers. Consult power utility if voltage is low. Ad-
just 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.
