Delivery temperature
sensor is faulty, the
wiring to the sensor is
broken, or the wiring or
connector is
disconnected.
Using the wiring schematic for the machine,
locate the Delivery 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 depending on the
results of the findings.

Fault
Dryer
temperature
high fault
Dryer air temperature is
too high to start or run
the compressor.
Check the site conditions and decrease
temperature of the dyer air temperature.

Warning
Dryer
temperature
high warning
Dryer air temperature is
approaching the
maximum limit to start or
run the compressor.
Check the site conditions and decrease
temperature of the dryer air temperature.

fault
Dryer air temperature is
too low to start or run the
compressor.
Check the site conditions and increase
temperature of the dryer air temperature.

warning
Dryer air temperature is

Fault
Dryer
temperature
short fault
Dryer temperature
sensor is faulty or the
wiring to the sensor is
shorted.
Using the wiring schematic for the machine,
locate the Dryer 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 depending on the

Oil Sump 1 temperature
is increasing at a rate
above the rate-of-rise

Inspect the oil level and condition. Add oil as
required. Inspect the oil cooler and thermal mixing
valve operation. Clean the cooler as required.
