Fault
Enclosure
temperature
open fault
Enclosure 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 Enclosure 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.
P.201
Fault
Plant Delivery
pressure high
fault
Plant delivery pressure
has exceeded the high
pressure fault limit.
Inspect process air piping downstream of
compressor package for blockages or closed
process valves. Check aftercooler for blockages.
Confirm adequate air storage for compressor
system.
P.201
Warning
Plant Delivery
pressure high
warning
Plant delivery pressure is
approaching the high
pressure fault limit.
Inspect process air piping downstream of
compressor package for blockages or closed
process valves. Check aftercooler for blockages.
Confirm adequate air storage for compressor
system.
P.202
Fault
Plant Delivery
pressure short
fault
Plant Delivery sensor is
faulty or the wiring to the
sensor is shorted.
Using the wiring schematic for the machine,
locate the plant delivery pressure sensor
connection to the controller. Check for any
shorted wires at the connector. Inspect the cable
for damage between the controller and the
sensor. Using a multi-meter with process clamp
meter measure the current (mA) in the signal wire
between the sensor and controller. The signal
should be in the range of 4-20mA.Replace or
repair the wiring or sensor depending on the
results of the findings.

Fault
Reservoir
pressure high
fault
Reservoir pressure has
exceeded the high
pressure fault limit.
Inspect inlet valve assembly for leaks and proper
sealing during unloaded operation. Confirm
proper adjustment of control pressure regulator if
equipped. Confirm proper operation of the
blowdown circuit. Check MPV for proper
operation. Inspect aftercooler for blockages.
