Page 22: Guide Elements
Application planning 4.5 Guide elements Guide elements Use the guide elements in the following cases: • A weight should be determined under the influence of transverse forces. • Horizontal movement of the load bearing implement should be prevented. A change in the distance between the support points, for example, as a result of expansion of the load bearing implement due to heat, must not lead to mutual tensioning of the guide elements. - Page 23 Application planning 4.5 Guide elements 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.

The load cell can be damaged when being handled improperly. Load cells are precision components. • Observe the operating instructions for the load cell. SIWAREX WL200 Operating instructions (https://support.industry.siemens.com/cs/ww/en/view/109749190) • Do not drop the load cell. • Protect the load cells from shocks. - Page 26 Installation 5.1 Safety information/instructions NOTICE Incorrect assembly of the load cell Damaging of load cells, installation parts or load bearing implement With load cells of smaller rated loads, there is a risk of stretching the load cell bodies when attaching force transfer devices, e.g. when tightening locknuts. Torsional and bending moments, eccentric loads and transverse loads are disturbance variables.
