| • Monitoring 6 guard doors, each with a magnetic safety sensor of the BNS range. • Start button with edge detection • 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. • If not all inputs are used, a bridge must be established at S x1 starting from S x2 of the input concerned. • Automatic start: The automatic start is programmed by connecting the feedback circuit to the terminals X1/X3. If the feedback circuit is not required, establish a bridge |
