Ready for start.READY TO START REMOTE CONTACTS CLOSED Machine timers complete, unit start will commence.READY TO START OCCUPIED MODE Machine timers complete, unit start will commence.STARTUP INHIBITED LOADSHED IN EFFECT CCN loadshed module commanding chiller to stop.READY TO START IN XX MIN START COMMAND IN EFFECT Chiller START/STOP on Status01 has been manually forced to start.Machine will start regardless of time schedule or remote contactstatus.C. IN RECYCLE SHUTDOWNPRIMARY MESSAGE SECONDARY MESSAGE PROBABLE CAUSE/REMEDYRECYCLE RESTART PENDING OCCUPIED MODE Unit in recycle mode, chilled water temperature is not high enoughto start.RECYCLE RESTART PENDING REMOTE CONTACT CLOSED Unit in recycle mode, chilled water temperature is not high enoughto start.RECYCLE RESTART PENDING START COMMAND IN EFFECT Chiller START/STOP on Status01 manually forced to start, chilledwater temperature is not high enough to start.RECYCLE RESTART PENDING ICE BUILD MODE Machine in ICE BUILD mode. Chilled Water/Brine Temperature issatisfied 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/REMEDYPRESTART ALERT STARTS LIMIT EXCEEDED STARTS EXCESSIVE Compressor Starts (8 in12 hours)Depress the RESET softkey if additional start isrequired. 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 timespan.PRESTART ALERT HIGH BEARING TEMPERATURE MTRB [VALUE] exceeded limit of [LIMIT]*.Check thrust bearing temperature.Check oil heater for proper operation, check forlow 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]*. Checkrefrigerant temperature.Check transducer accuracy. Check for low chilledwater/brine supply temperature.PRESTART ALERT LOW OIL TEMPERATURE OILT [VALUE] exceeded limit of [LIMIT]*.Check oil temperature. Check oil heater power, oil heater relay. Checkoil 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]*. Checkcondenser 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.86
