status.
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
Machine in ICE BUILD mode. Chilled Water/Brine Temperature 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.
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.
