Relays K1 and K2 must have forced contacts. They are operated directly at the two
failsafe semiconductor outputs OSSD 1 (X1-12) and OSSD 2 (X1-11).
A suitable mechanism must be provided for extinguishing sparks. Please note that
doing this will cause the switching time to be extended.
Channels “x” and “y” must be integrated for Category 3 in accordance with DIN EN 954-
1. Integrating one channel based on “z” is only permitted with a one-channel control
system and taking into consideration the results of a risk analysis.
Serial machine controls are admissible only insofar the valid regulations allow.
