8 Error messages
LCD display messages
The LCD HMI in case of transmitter errors or malfunctioning is capable of displaying specific error/fault messages to help the user
in identifying the problem and resolve it. In case of an alarm, a message consisting of an icon and text appears at the bottom of the
process display, as shown hereafter.
Icon Description
Error / Failure
Functional check (e.g. during simulation )
Out of Spec (e.g. operating with empty meter pipe)
Maintenance required
In the error description, the error number is displayed in the second line (F098.034). Two further lines are used to describe the
error. The device status is divided into four groups. The message text beside this icon in the display provides information about
where to look for the error. There are the following areas:
Electronic, Sensor, Configuration, Operanting and Process .

F 116.023 Electronic
memory
failure
The device data loaded at the start
up from the electronics NV-memory
are corrupted precluding the correct
functionality of the device.
During the start-up the device
firmware execute a check of the
device database and if the CRC
doesn’t match what expected the
firmware stops its execution and the
output signal goes to fail safe value.
EMC problems like electrostatic
discharge (ESD), burst, surge
outside the specification limits
and/or soft errors (ionic radiation)
could corrupt memory data.
The device must be
replaced or
the database must be
reloaded.

F 108.040 Output
read-back
failure
The reading of the 4-20mA output
signal is too different from what should
have been generated.
The output circuit could be broken
or
not correctly calibrated.
A DAC (digital to output
converter) trimming
should be performed
and if the error persists
consider to replace the
device.

"The data in the sensor memory
are corrupted precluding the correct

During the start-up the device firmware
execute a check of the device data-base
and if the calculated CRC doesn’t match

F 114.000 P-dP sensor
failure
The sensor signal value is missing or
incorrect due to a mechanical failure.
There could be a bad or broken
connection between sensor and
electronics and/or a mechanical
damage of the sensor not
generating anymore valid primary
signals. Loss of fill fluid from the
cell, ruptured diaphragm, other.
The device must be
replaced

temperature
failure
The measurement accuracy is decreased.
The current process value is
compensated with the last valid value of
the Sensor temperature.
The circuitry for the sampling of
the temperature has failed.
