The proximity sensor or switch controls a form C changeover relay contact for the safe area load. The barrier output changes state when the input
signal changes state. The normal output state can be reversed using switch S1. Switch S3 is used to enable or disable line fault detection of the
field circuit.
During an error condition, relays revert to their de-energized state and LEDs indicate the fault according to NAMUR NE44.

The device is voltage and temperature to stabilize and ensures a defined switching behavior.
The device can be used as on/off control or as a Minimum/ Maximum control. A signal delay can be set in the range between 0.5 s and 10 s.
The device is equipped with a line break monitoring (electricity free Relay in case of error). The line break is indicated by a red LED. By using the line break monitoring the output is used as an error signal output. When disabled, the LB-Monitoring output II follows the output I.
