9 Maintenance and fault rectification
VEGAMET 391 • 4 … 20 mA/HART
36032-EN-130701
The signal conditioning instrument and the connected sensors are
permanently monitored during operation and the values entered dur-
ing parameter adjustment are checked for plausibility. If irregularities
occur or in case of incorrect parameter adjustment, a fault signal is
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 Rectification
E003 CRC error (error with
self-check)
– Carry out a reset
– Send instrument for repair
E007 Sensor type not com-
patible
– Search for sensor again and allocate
under "Meas. loop - Input"
E008 Sensor not found – Check connection of the sensor
– Check HART address of the sensor
E013 Sensor signals
failure, no valid
measured value
– Check sensor parameter adjustment
– Send sensor for repair
E014 Sensor current
> 21 mA or short-
circuit
– Check sensor, e.g. on failure
– Remove short-circuit
E015 Sensor in boot phase
Sensor current
< 3.6 mA or line
break
– Check sensor, e.g. on failure
– Remove line break
– Check connection of the sensor
E016 Empty/full adjustment
reversed
– Carry out a fresh adjustment
E017 Adjustment span too
small
– Carry out a fresh adjustment and
increase the distance between min.
and max. adjustment
E021 Scaling span too
small
– Carry out a fresh scaling, increase
the distance between min. and max.
scaling.
E030 Sensor in boot phase
Measured value not
valid
– Check sensor parameter adjustment
E034 EEPROM CRC error – Switch the instrument off and on
– Carry out a reset
– Send instrument for repair
E035 ROM CRC error – Switch the instrument off and on
– Carry out a reset
– Send instrument for repair
E036 Instrument software
not executable (dur-
ing software update
or after failed update)
– Wait until software update is finished
– Carry out another software update
