P.205
Fault
Reservoir
pressure short
fault
Reservoir pressure
sensor is faulty or the
wiring to the sensor is
shorted.
Using the wiring schematic for the machine,
locate the Reservoir 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 open
fault
Reservoir pressure
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 Reservoir pressure sensor connection
to the controller. Check for disconnected wires,
plugs, or loose connections. 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
Separator
pressure high
fault
Separator 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.

Warning
Separator

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
