Safety PE-Beam System
All safety beams are setup in fail-safe mode; hence, the PNP-
Output is switched on during normal operation and switched off
when an object is detected.
In addition, each light beam is monitored for proper operation.
Meaning that if a light beam shows detection for longer than 30 sec-
onds the controller assumes that the light beam is malfunctioning
(e.g. dirt).
