Possible Cause
The sensor is detecting that
the time between
measurements has exceeded
the allowed time limit.
This is set due to a sensor
board fault or power
accumulator fault.
The unit is in factory / test
mode.
The sensor is in Low Power
Mode.
The sensor is unable to detect
the reference reflection for
level measurement in direct or
remote mount transmitters or
process connector reflection in
remote mount transmitters.
Sensor board NVRAM data
has been corrupted.
Comm sensor database
Parameter Inconsistent
Communication firmware is
not compatible with sensor
firmware.

Recommended Action
Ensure the configuration is correct
and restart the device. If the problem
persists, replacement of the Sensor
housing may be necessary.
Power cycle the device if problem
persists replace the Sensor housing.
Restart the device.
The Sensor can be reset through a
soft or hard restart.
Upload an echo curve and confirm
that the reference and process
connector (only for remote mounts)
model parameters are set for a good
match with actual reflections. Perform
a soft or hard reset.
Use sensor NVRAM corrupt reset
method from host to clear the sensor
NVRAM error.
This method will default the sensor
NVRAM data.
This will reset the critical NVRAM
corruption alarm but the non-critical
not characterized/calibrated alarms
will stay.
If the problem persist then change the
sensor module.
Check the cable between
Communication module and Sensor
housing is correct.
Power cycle the device if problem still
persists load the correct
communication and sensor firmware
versions.
Update communication and sensor
boards with compatible version of
firmware.
Check with Service person/support
team for version details.
