triggered. In case of an instrument defect or line break/shortcircuit, a
fault signal is also triggered.
The fail safe relay deenergises in case of failure, the failure indica-
tion lights and the current outputs react according to their configured
control behaviour. In addition, one of the following fault messages is
outputted on the display.
Error code Cause
E003 CRC error (error with
self-check)
E007 Sensor type not com-
patible
E008 Sensor not found
E013 Sensor signals error,
no valid measured
value
E016 Empty/full adjustment
reversed
E017 Adjustment span too
small
E021 Scaling span too
small
E030 Sensor in boot phase
Measured value not
valid
E034 EEPROM CRC error
E035 ROM CRC error
E036 Instrument software
not executable (dur-
ing software update
and after failed up-
date)
E053 Sensor measuring
range is not read cor-
rectly
E104 Measurement loop
deactivated
Depending on the reason for the fault and the measures taken, the
steps described in chapter "Set up" may have to be carried out again.

Rectification
– Carry out a reset
– Send instrument for repair
– Search for sensor again and allocate
under "Meas. loop - Input"
– Check connection of the sensor
– Check HART address of the sensor
– Check sensor parameter adjustment
– Send sensor for repair
– Carry out a fresh adjustment
– Carry out a fresh adjustment and
increase the distance between min.
and max. adjustment
– Carry out a fresh scaling, increase
the distance between min. and max.
scaling.
– Check sensor parameter adjustment
– Switch the instrument off and on
– Carry out a reset
– Send instrument for repair
– Switch the instrument off and on
– Carry out a reset
– Send instrument for repair
– Wait until software update is finished
– Carry out another software update
– Communication error: Check sensor
cable and screening
– Activate measurement loop (alloca-
tion of a sensor to a measurement
loop)
