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.
Supply

(Maintenance)
Supply Press
High (Enabled)
The supply pressure
reading is above the user
adjusted threshold.
None − indicates a
condition that could
cause damage to the
instrument or actuator.
Confirm proper
air supply.
The Supply Pressure
sensor on-board has
detected an abnormally
high supply pressure.
Verify the proper supply
pressure and that the
alert is properly set.
Supply Press Low
(Enabled)
The supply pressure
reading is below the user
adjusted threshold
None − indicates a
condition that could
reduce performance or
prevent the valve from
shutting tightly.
The Supply Pressure
sensor on-board has
detected an abnormally
low supply pressure.
Verify the proper supply
pressure and that the
alert is properly set.
Temperature
Limit
(Environment)
User Config.
(Advisory)
Temperature High
(Enabled)
The instrument temperature
is above the user adjusted
threshold.
None − indicates a
condition that could
shorten service life or
lead to reduced
performance.
Check
instrument
environment.
The instrument
temperature has
exceeded the user
configured high
temperature limit.
Operation of the
instrument above the
rated temperature may
degrade instrument
components. This may
affect instrument
performance and/or
reduce the life of the
instrument.
Temperature Low
(Enabled)
The instrument temperature
is below the user adjusted
threshold.
The instrument
temperature has
dropped below the user
configured low
temperature limit.
Operation of the
instrument below the
rated temperature may
degrade instrument
components. This may
affect instrument
performance and/or
reduce the life of the
instrument.
