Integrating the SIMATIC FS600 Laser Scanner with External Wiring with
Relays and Quadruple Zone Pair Changeover
In this connection example, the restart interlock function is provided by the connected
command unit "WA", which applies the voltage of 24 V to the input RESTART X1-2. The
SIMATIC FS600 Laser Scanner itself must be configured using the "SIMATIC FS600
Parameterization Software LS4soft" user software so that the operating mode "with
restart interlock" is active.

Fig. 8.1-1:
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).
Relay K3 has a deenergizing delay. 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.
