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.
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 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 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.
PRESTART ALERT HIGH GEAR OIL TEMP GEAOILT [VALUE] exceeded limit of [LIMIT].*
Check gear oil cooler flow. Check for cooler water flow. Check sensor for
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.
