Check the condition of compressor cooling
functions such as thermal mixing valve and
cooler. Check oil condition and oil level. Examine
airend for issues. Review history of compressor
discharge temperature using the controller trends,
data logs, or site maintenance log. Perform
adjustments, cleaning, or repair based on the
results of the investigation.

sensor is faulty, or the
wiring to the sensor is
shorted.
Using the wiring schematic for the machine,
locate the separator temperature sensor
connection to the controller. Check for any
shorted wires at the connector. Inspect the cable
for damage between the controller and the
sensor. Remove the cable connector from the
sensor and use a multi-meter to check the
resistance of the sensor and ensure that it is not
shorted. It is possible that the sensor may read
within range at room temperature but still be
faulty once exposed to an elevated temperature
or vibration. Replace or repair the wiring or
sensor as needed.

sensor is faulty, or the
connection between the
sensor and controller is
disconnected.
Using the wiring schematic for the machine,
locate the separator temperature sensor
connection to the controller. Check for
disconnected wires, plugs, or loose connections.
Inspect the cable for damage between the
controller and the sensor. Remove the cable
connector from the sensor and use a multi-meter
to check the resistance of the sensor and ensure
that it is not open (very high resistance) It is
possible that the sensor may read within range at
room temperature but still be faulty once exposed
to an elevated temperature or vibration. Replace
or repair the wiring or sensor as needed.

Ambient air temperature
is too high to start or run
the compressor.
Check the site conditions and decrease
temperature of the ambient air to the compressor
enclosure.

Ambient air temperature
is approaching the

Ambient air temperature
is too low to start or run
the compressor.
Check the site conditions and increase
