triggered. In case of an instrument defect or line break/shortcircuit, a
fault signal is also triggered.
The fault indication lights up in case of failure and the current output
as well as the relays react according to the configured fault mode. If
the fail safe relay was configured, it will deenergize. In addition, one of
the following error 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,

E015 Sensor in boot phase
Sensor current
< 3.6 mA or line

ing software update
and after failed up-
date)
E053 Sensor measuring
range is not read cor-
rectly
9 Maintenance and fault rectification
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
– Check sensor, e.g. on failure
– Remove short-circuit
– Check sensor, e.g. on failure
– Remove line break
– Check connection of the sensor
– 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
