9 Maintenance and fault rectification

VEGAMET 625 • Double channel HART

28970-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

E011

No HART sensor as-

signed

– Assign a sensor in the menu "Input"

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.

E026

Units of the input

variable are differ-

ent (only differential

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 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
