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.
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.
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.
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 voltage transform-
ers. Consult power utility if voltage is low. Cali-
brate voltage reading on STATUS01 Table.
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. Cali-
brate voltage reading on STATUS01 table.
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., set point predefined or selected by the operator as an override, alert, or alarm condition. [VALUE]
is the actual pressure, temperature, voltage, etc., at which the control tripped.
