Wave
With the wave function, a safety laser scanner that is to be configured in a network can be
identified more easily from its position.
When starting the automatic search for a safety laser scanner in a network the wave button
can be selected.

Example of a special operating condition:
Material is transported into the protective zone on a conveyor and the safety laser scan-
ner is overridden for the time it takes the material to pass through.
Muting proves to be particularly suitable when, under certain operating conditions, an object
is permitted to pass through the danger zone but a person is not.
