DANGER
Use e
xternal device monitoring!
The safety switch does not feature external device monitoring. To reach SIL3/PL e, you
must therefore implement external device monitoring with the help of a suitable higher-
level safety evaluation.
The actually achieved performance level or safety integrity level depends on the exter‐
nal wiring, the wiring version, the selection of control switches and their arrangement
on the machine.
Evaluate both safety outputs!
Both safety outputs (OSSD 1 and OSSD 2) must be evaluated without fail in order to
guarantee safety.
