Compressor Warning Condition
#
Flashes
Green LED - Warning Condition
(The Compressor May Run With These Conditions)
1
Low oil pressure - Indicates that the device has detected low oil pressure for longer
than 2 seconds. The compressor is able to run, because not enough time has elapsed
without oil pressure to cause a shutdown. The warning will clear if 2 seconds of good
oil pressure is detected.
2
Not used
3
Discharge Temperature Probe Open Or Disconnected - The system is not reading
temperature data from the discharge temperature sensor input. The compressor is able
to run when this condition is present. The condition will clear if the system reads valid
temperature data from the probe for
more than 2 seconds.
4
Current Sensor Disconnected - The current sensor is not connected to the system. The
compressor continues to run. The condition will clear when the current sensor is
connected to the module for more than two seconds.
5
Communication Error Between CoreSense Protection Module And E2 –
A. The rack controller is not communicating with the CoreSense module. The
compressor continues to run. The condition will clear when a valid message is
received from the rack controller.
B. If the E2 is configured to expect a Sensor Module and none is supplied, the module
will flash Code “5”
