6.6 Connection of multiple sensors per sensor circuit
ASO sensors must not be connected in parallel.
One or more sensors (e.g. safety contact edges) can be connected to sensor inputs 3 11 or 3 10. For this
purpose, the individual sensors can be connected in series.
An unused input can be bridged with an 8.2 k� resistor.
