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
