Travel Sensor
(Sensors)
(Failed)
Travel Sensor
(Enabled)
The travel feedback is within
acceptable limits.
If configured for Self Test
Shutdown, then the transducer
“Actual” mode is placed Out of
Service until the problem is
fixed. Out of service results in
the actuator being at the Zero
Power Condition.
Check mounting
and linkage
Travel feedback value is
outside expected
limits. If this problem
occurs during
instrument set‐up, the
most likely cause is
faulty mounting or
improper adjustment
of the travel sensor. If
this problem occurs
during normal
operation, the most
likely cause is a failure
of the travel sensor.
To correct,
1) Insure proper
mounting and linkage
adjustment.
2) Inspect and test
travel sensor
3) Toggle the
transducer target
mode.
If the problem persists,
replace the printed
wiring board (PWB)
assembly.
Output Press Sensor

(Maintenance)
Port A Pressure
Sensor (Enabled)
The pressure sensor reading is
outside the functional range of
the sensor.
If configured for Self Test
Shutdown, then the transducer
“Actual” mode is placed Out of
Service until the problem is
fixed. Out of service results in
the actuator being at the “No
Power” condition.
Confirm proper
air supply
The pressure sensor
on‐board the device
has failed. This may be
due to excessive supply
pressure or
contaminated air.
If it is verified that the
air supply is ok, replace
the printed wiring
board (PWB) assembly.
Port B Pressure
Sensor (Enabled)
None - Indicates a possible
hardware problem that would
degrade diagnostic capability.
Supply Press Sensor
(Sensors)
(Advisory)
Supply Press
Sensor (Enabled)
The pressure sensor reading is
outside the functional range of
the sensor.
None - Indicates a possible
hardware problem that would
degrade diagnostic capability.
Confirm proper
air supply
The pressure sensor
on‐board the device
has failed. This may be
due to excessive supply
pressure or

If it is verified that the
air supply is ok, replace
the printed wiring

Temperature Sensor
(Sensors)
(Advisory)
Temperature
Sensor (Enabled)
The temperature sensor
reading is outside the
functional range of the sensor.
None - Indicates a possible
hardware problem that would
degrade instrument calibration
and diagnostic capability.
Replace PWB
assembly.
The temperature
sensor on‐board the
device has failed or the
unit has been exposed
to an temperature
extreme beyond the
recommended limits.
