3.2 Intended use
The optoelectronic level switches should only be used for level
control or monitoring of liquid media. Their scope of application is
defined by their technical performance limits and their materials.
Improper use is defined as any application that exceeds the technical
performance limits or is not compatible with the materials. Checking
against improper use is the responsibility of the operator.
The liquids must not have any large contamination or coarse
■
particulates and must not have a tendency to crystallise. Ensure
that the wetted materials of the switch are sufficiently resistant to
the medium being monitored. Not suitable for dispersion, abrasive
liquids, highly viscous media and colours.
This instrument is not permitted to be used in hazardous areas!
■
The maximum power and voltage values as specified in the
■
operating instructions should be adhered to.
