5.1 Single-channel sensor circuit
The sensor circuit is not designed with redundancy.
The safety relay does not detect short and cross-circuits in the sensor circuit.
5.2 Two-channel sensor circuit
The sensor circuit is designed with redundancy.
With the corresponding wiring, the safety relay detects short and cross-cir-
cuits in the sensor circuit.
5.3 Automatic start
The device starts automatically after the sensor circuit has been closed.
5.4 Manual, monitored start
When the sensor circuit is closed, the device starts once the start circuit has
been closed and opened again by pressing and releasing the reset button.
A connected reset button is monitored.
5.5 Safe shutdown
When the sensor circuit opens, the enabling current paths open without
delay.
When the enabling current paths are open, the device is in the safe state.
The signaling current path closes.
