Error messages and troubleshooting

8.1

Repair

Note
Unnecessary costs for repairs
Please only return faulty load cells to our repair center accompanied by an accurate
description of the fault. This simplifies the diagnostics.
8.2

Error messages

Rated load exceeded
If load cells are loaded beyond their rated load, this can result in an error message in the
weighing module.
When step changes in load cannot be excluded during measuring, for example, due to
application of a load in free fall, appropriate precautions to avoid damage to the load cell
must be made, e.g. by using elastomer bearings or load cells dimensioned for higher rated
loads.
Wire break
The weighing module reports a wire break if the jumpers are not installed in load cells with
four-wire technology. For details, see section Connecting up (Page 24).
8.3

Checking the mechanical and electrical configuration

In the case of faulty measurements, check the following:
● Do any force bypasses exist, e.g. due to cables, pipes or guides, that generate forces in
the measuring direction?
● Are there any other disturbances due to soiling or thermal expansion?
● Have all load cells been correctly aligned horizontally and at the same height?
● Has moisture penetrated the junction box?
● Are the cables connected correctly?
● Are the cables damaged?
