What the Alert is Detecting
(Default)
The travel feedback is within
acceptable limits.
The pressure sensor reading is
outside the functional range of
the sensor.
The pressure sensor reading is
outside the functional range of
the sensor.
The temperature sensor
reading is outside the
functional range of the sensor.
Effect on Valve/Instrument
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.
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.
None - Indicates a possible

Action
Check mounting Travel feedback value is
and linkage 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.
Confirm proper The pressure sensor
air supply 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.
