Fig. 8.2-1:
In this example, the relay monitoring is performed by an external safety module (e.g.
MSI-SR2/F). Relays K4 and K5 must be equipped with positively guided contacts. A
suitable mechanism must be provided for extinguishing sparks. Please note that doing
this will cause the switching time to be extended.
Please refer to the operating instructions for the components.
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.
