1.9 Function description
Single-channel sensor circuit
The sensor circuit does not have any redundancy.
The safety relay will not detect any short-circuits or cross-faults in the sensor
circuit.
Dual-channel sensor circuit
The dual-channel sensor circuit is connected the same.
The following variants are possible:
•
Dual-channel without cross-circuit detection
•
dual-channel with cross-circuit detection
Section 3.4.3, "Terminal models Signal encoder", page28
Automatic start
The device will start automatically after the sensor circuit is closed.
Manual, monitored start
If the sensor circuit is closed, the device will start after the start circuit is
closed by pressing the reset button.
A connected reset pushbutton (connection to S34) is monitored.

Section 1.10, "Function and time diagrams", page10
Safe shut-down
When the sensor circuit is opened, enable current paths S13/14, 23/2, and
33/34 will be opened without delay.
When the enable current paths are open, the device will be in a safe state.
The signal current path closes.
