Memory Failure
Possible Cause
Current saturated high or low
Write non-volatile command
received from CB
Non-volatile Storage in
progress
The Level sensor trim is set to
a default value
The Temperature trimming
configuration is corrupted
Device change requires restart
An attempt to save data to the
sensor module has failed
A temperature measurement
has resulted in a value outside
of the operating range
An error occurred in the sensor
module Possible causes could
be a failed component in the
sensor electronics, a
configuration error, or the
sensor assembly
An error occurred in the
communication between the
sensor and electronics
modules
An error occurred in the sensor
module Possible causes could
be a failed component in the
sensor electronics or an error
changing the configuration
Writing to the sensor non-
volatile memory was not
successful
Suggested Action
Check process conditions and/or device
configuration The compatibility of level
transmitter model and process conditions has to
be checked Probably a different transmitter type
is required
Information only
Contact service to perform a factory level sensor
trim
Restart device
Restart the device If the condition persists
contact service
Restart the device If the condition persists
contact service for a replacement
Using a HART configurator (DTM - Hand held) or
the local HMI, navigate to the Diagnostics ->
Waveform display and confirm the quality of the
signal The signal peak should visibly cross the
threshold line and should measure approximately
2 Volts. Contact ABB service for additional
support or a replacement if the condition
persists
Restart the device If the condition persists
contact service for a replacement
Restart the device If the condition persists
contact service for a replacement
The sensor should be replaced as soon as
possible
