9 Maintenance and fault rectification
VEGASCAN 693 • 15-channel HART signal conditioning instrument
29252-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 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 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
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
E053 Sensor measuring
range not read cor-
rectly
– Communication error: Check sensor
cable and screening
E104 Measurement loop
deactivated
– Activate measurement loop (alloca-
tion of a sensor to a measurement
loop)
