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 3.4.4, "Connection options Start and feedback circuit", page28

￫

 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.
