Stationary hazardous area

Using the safety laser scanner, you can monitor a stationary danger zone, e.g. the environ-
ment of a machine that is installed in a fixed position.
The monitored area can be divided into subsections, for which monitoring can be activated
and deactivated each.

Multiple evaluation

When multiple evaluation is active, an object has to be scanned several times consecut-
ively before the safety laser scanner switches the OSSDs to the OFF state. This reduces
the probability that insects, welding sparks or other particles lead to a shutdown of a plant.
If a multiple evaluation of 4 is configured, an object has to be detected 4 times in succes-
sion in the safety zone, so that the safety laser scanner switches the OSSDs to the OFF
state.
With a multiple evaluation > 2 an allowance has to be made to the response time. The
height of the allowance (see
the value of the multiple evaluation and the valid response time (see
