4. Intended use
The switching device can only fulfill its safety-relevant task, if it is used as intended within specifications.
The intended use of the switching device is the use as a protection system in connection with safety contact
mats, safety bumpers and safety contact edges with 8.2 kΩ resistance for steady-state current monitoring.
A different use or any use going beyond the intended use is not within specifications. The manufacturer
does not accept any liability for any damage arising from use not within specifications.
Any use for special applications requires prior release by the manufacturer.

Safety-orientated monitoring of a safety contact strip with start release via release pushbutton and separate
continuation of the control circuits (category 3 compliant application according to EN ISO 13849-1).
In order to check the functionality of the load breaking K1 and K2 relays the break contacts of these contactors
are integrated into the start circuit (RESET).
The signaling relay output is used to visualize the switching state of the safety contact edge.
