Wiring example
- Note (Wiring diagram)
- The wiring diagram is shown with guard doors closed and in de-energised condition. | Monitoring 1 guard door(s), each with a magnetic safety sensor of the BNS range | 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 reliable down-rated contactor. A second contactor leads to an increase in the level of security by redundant switching to switch the load off. | To secure a guard door up to PL e and Category 4 | The feedback circuit monitors the position of the contactors KA and KB. | 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.
