Oil Pressure Sensor Fault 
Alarm description (as shown on screen): OilPressSensFault N 
Trigger: Sensor shorted or open 
Action Taken: Normal shutdown of circuit 
Reset: This alarm can be cleared manually via the keypad, but only if the sensor 
is back in range. 
Suction Temperature Sensor Fault 
Alarm description (as shown on screen): SuctTempSensFault N 
Trigger: Sensor shorted or open 
Action Taken: Normal shutdown of circuit 
Reset: This alarm can be cleared manually via the keypad, but only if the sensor 
is back in range. 
Discharge Temperature Sensor Fault 
Alarm description (as shown on screen): DiscTempSensFault N 
Trigger: Sensor shorted or open 
Action Taken: Normal shutdown of circuit 
Reset: This alarm can be cleared manually via the keypad, but only if the sensor 
is back in range. 
Motor Temperature Sensor Fault

Circuit Events 
The following events limit operation of the circuit in some way as described in the 
Action Taken column. The occurrence of a circuit event only affects the circuit on which 
it occurred. Circuit events are logged in the event log on the unit controller. 
Low Evaporator Pressure - Hold 
Event description (as shown on screen): EvapPress Low Hold N 
Trigger: This event is not enabled until the circuit startup is complete and the unit 
mode is Cool. Then, while running, if evaporator pressure <= Low Evaporator 
Pressure Hold set point the event is triggered. The event is not to be triggered for 
90 seconds following the capacity change of the compressor from 50% to 60%. 
Action Taken: Inhibit loading. 
Reset: While still running, the event will be reset if evaporator pressure > (Low 
Evaporator Pressure Hold SP + 2psi). The event is also reset if the unit mode is 
switched to Ice, or the circuit is no longer in the run state. 
 Low Evaporator Pressure - Unload 
Event description (as shown on screen): EvapPressLowUnload N 
Trigger: This event is not enabled until the circuit startup is complete and the unit 
mode is Cool. Then, while running, if evaporator pressure <= Low Evaporator 
Pressure Unload set point the event is triggered. The event is not to be triggered 
for 90 seconds following the capacity change of the compressor from 50% to 
60%.
