12.  Troubleshooting

 

•

Warning! 

The electrical installation must only be checked by expert personnel. 

Problem

Cause

Measure

Measuring system 
does not work.

Power supply 
interrupted.

Check the power supply.

Cable break.

Check the connecting cables for a possible break of a 
cable.

Defective fuse.

Exchange the fuse in the field housing.

Defective device.

Call ENVEA Process for further instructions.

Measuring system 
outputs wrong 
values.

Incorrect calibration.

Delete input signal correction, new calibration according 
to section 7.

Calibration shifted by 
abrasion or caking on 
front end of sensor.

Delete input signal correction, new calibration according 
to section 7.

Sensor error.

Sensor not properly 
connected.

Check cable.

Sensor damaged.

Replace sensor.

No 24 V DC supply on 
sensor.

Assure right power supply.

Relay flickering.

Hysteresis too small.

Increase hysteresis, check effects caused by external 
devices.

Do not open, as otherwise the warranty claim expires!

13.  Reliability

For any questions concerning the sensor reliability (MTTF), please contact ENVEA Process.
