Siemens SIWAREX WL230 BB-S SA Manuel d'utilisation
Three guide elements are sufficient to statically fix a weighing platform or container.
Note
Weighing errors
With four guide elements, there is a risk of the guide elements mutually tensioning, which in turn
induces weighing errors. If you nevertheless want to use four guide elements, the guide
elements must be installed with a sufficient amount of play.
Ensure that the guide elements to be used comply with the principles applicable to weighing
technology.

Grounding cable

The grounding cable is used to protect the load cells from undesired currents. The causes of
such currents are, for example:
● Equalizing currents with missing or faulty equipotential bonding conductors
● A lightning strike nearby
● Welding work
● Static charge
