11.  Warranty

Warranty is granted for one year starting from delivery date under the condition that the operating instructions 
have been followed, no interventions on the appliances have been made and the components of the system show 
no mechanical damage or wear resistance. 
 
In case of a defect during the warranty period, defective components are repaired or are replaced free of charge. 
Replaced parts turn into the property of ENVEA - SWR engineering. If desired by the costumer that the parts  
should be repaired or replaced in its factory, then the costumer has to take over the costs for the ENVEA - SWR 
engineering-service staff. 
 
ENVEA - SWR engineering is not responsible for damage, which did not develop at the delivery article; especially 
ENVEA - SWR engineering is not responsible for escaped profit or other financial damages of the customer.

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 - SWR engineering 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!
