                CONNECTION DIAGRAM

In use of the application below the simultaneousness of both switches is monitored (less than 0,5 s). This behaviour corresponds to EN 954-1 safety category 4.

This application is suitable for type II of DIN EN 574 and corresponds to EN 954-1 safety category 3.

Wiring changes during operation are not allowed and lead to a failure message.

Application corresponds to EN 954-1 type IIIc and safety category 4, EN IEC 62061 up to SIL3 and EN ISO 13849-1 up to PLe.
