notice
 
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
 
notice - Wiring example
 
To secure a guard door up to PL 4 and Category #03#
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.
If only one external relay or contactor is used to switch the load, the system can be classified in Control Category 3 to EN 954-1, 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.
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
The wiring diagram is shown with guard doors closed and in de-energised condition.
