PRIMARY CAUSE
Depress the RESET softkey if additional start is
required. Reassess start-up requirements.
Check oil heater for proper operation.
Check for low oil level, partially closed coil supply
valves, clogged oil filters, etc.
Check the sensor wiring and accuracy.
Check configurable range in SETUP1 screen.
Check motor sensors for wiring and accuracy.
Check motor cooling line for proper operation, or
restrictions.
Check for excessive starts within a short time span.
Check configurable range in SETUP1 screen.
Allow discharge sensor to cool.
Check for sensor wiring and accuracy.
Check for excessive starts.
Check configurable range in SETUP1 screen.
Check transducer wiring and accuracy.
Check for low chilled fluid supply temperatures.
Check refrigerant charge.
Check oil heater contactor/relay and power.
Check oil level and oil pump operation.
Check transducer wiring and accuracy.
Check for high condenser water temperatures.
Check voltage supply. Check voltage transformers.
Consult power utility if voltage is low.
Check voltage supply.
Check power transformers.
Consult power utility if voltage is high.
Calibrate guide vane actuator in Control Test.
