Monitoring 1 guard door(s), each with a magnetic safety sensor of the BNS range | The feedback circuit monitors the position of the contactors KA and KB. | To secure a guard door up to PL e and Category 4 | Automatic start: The automatic start is programmed by connecting the feedback circuit to the terminals X1/X2. If the feedback circuit is not required, establish a bridge. | If only one external relay or contactor is used to switch the load, the system can be classified in Control Category 3 to ISO 13849-1, if exclusion of the fault “Failure of the external contactor” can be substantiated and is documented, e.g. by using a re | The wiring diagram is shown with guard doors closed and in de-energised condition.
