VEGAMET 625 • Double channel HART
28970-EN-150129
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congured
control behaviour. In addition, one of the following fault messages is
outputted on the display.
Error code Cause Rectication
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
E011 No HART sensor as-
signed
– Assignasensorinthemenu"Input"
E013 Sensor signals error,
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.
E026 Units of the input
variablearedier-
ent(onlydierential
measurement loop)
– Adapt the units of both
– Use sensors with the same input
variable
E030 Sensor in boot phase
Measured value not
valid
– Check sensor parameter adjustment
E034 EEPROM CRC error
– Switchtheinstrumentoandon
– Carry out a reset
– Send instrument for repair
E035 ROM CRC error
– Switchtheinstrumentoandon
– Carry out a reset
– Send instrument for repair
E036 Instrument software
not executable (dur-
ing software update
and after failed up-
date)
– Waiting until software update is
nished
– Carry out another software update
