3. Safety
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.
Do not operate the instruments in the immediate vicinity of strong
■
electromagnetic fields or in the immediate vicinity of equipment that
can be affected by magnetic fields (min. clearance 1 m).
The responsiveness of the instrument is preset and cannot be
■
adjusted.
The switches must not be exposed to heavy mechanical strain
■
(impact, bending, vibration).
The instrument has been designed and built solely for the intended use
described here, and may only be used accordingly.
The manufacturer shall not be liable for claims of any type based on
operation contrary to the intended use.
