P.211
Fault
System
pressure short
fault
System pressure sensor
is faulty or the wiring to
the sensor is shorted.
Using the wiring schematic for the machine,
locate the System 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.
P.212
Fault
System
pressure open
fault
System 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 System 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.
P.225
Fault
Oil Injection
pressure low
fault
Oil injection pressure is
below the low fault
pressure limit.
Inspect the oil level and condition. Add oil as
required. Inspect the oil cooler and thermal mixing
valve operation. Confirm proper operation of the
oil pump.
P.225
Warning
Oil Injection
pressure low
warning
Oil injection pressure is
approaching the low fault
pressure limit.
Inspect the oil level and condition. Add oil as
required. Inspect the oil cooler and thermal mixing
valve operation. Confirm proper operation of the
oil pump.
P.226
Fault
Oil Injection
pressure high
fault
Oil injection pressure has
exceeded the high
pressure fault limit.
Inspect the oil system, pump, and cooler for
blockages. Confirm proper operation of the oil
pump.
P.226
Warning
Oil Injection
pressure high
warning
Oil injection pressure has
exceeded the high
pressure warning limit
and is approaching the
fault limit.
Inspect the oil system, pump, and cooler for
blockages. Confirm proper operation of the oil
pump.
P.227
Fault
Oil Injection
pressure short
fault
Oil Injection pressure
sensor is faulty or the
wiring to the sensor is
shorted.
Using the wiring schematic for the machine,
locate the Oil Injection 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. Replace or repair the wiring or sensor
depending on the results of the findings.
P.228
Fault
Oil Injection
pressure open
fault
Oil Injection 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 Oil Injection 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. Replace or repair the
wiring or sensor depending on the results of the
findings.
P.312
Warning
Remote speed
control short
fault
Remote speed control
input is faulty or the
wiring to the sensor is
shorted.
Using the wiring schematic for the machine,
locate the Remote speed control input connection
to the controller. Check for any shorted wires at
the connector. Inspect the cable for damage
between the controller and the Remote speed
control. Replace or repair the wiring or sensor
depending on the results of the findings.
