A1.10
Warning
Airend Inlet
Pressure Input
is below the
Warning Limit
Airend inlet pressure is
approaching the
minimum value to be
able to start or run the
machine.
Inspect inlet air filter, clean/replace as necessary.
A1.12
Fault
Airend Inlet
Pressure
Input is shorted,
check sensor
wiring
Airend Inlet Pressure
sensor is faulty or the
wiring to the sensor is
shorted.
Using the wiring schematic for the machine,
locate the airend inlet 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.
A1.13
Fault
Airend Inlet
Pressure Input
is open, check
sensor wiring.
Airend Inlet 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 airend inlet 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.
A1.15
Fault
Discharge
pressure above
the Fault Limit.
The package discharge
pressure has exceeded
the fault limit.
Inspect the oil level and condition. Check the
performance of the thermal mixing valve and oil
cooler if equipped.
A1.15
Warning
Discharge
pressure above
the Warning
Limit
The package discharge
pressure has exceeded
the warning limit and is
approaching the fault
limit.
Inspect the oil level and condition. Check the
performance of the thermal mixing valve and oil
cooler if equipped.
A1.16
Fault
Discharge
pressure sensor
shorted
Discharge pressure input
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.
A1.17
Fault
Discharge
pressure sensor
open
Discharge pressure input
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 plant delivery 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.
