Multiplex operation
In this operating mode the mutual interference of adjacent sensors can be reliably avoided. For this purpose, each sensor is wired
with a separate output of the control.
The devices operate in multiplex operation with a cyclically time-delayed transmission pulse and are switched to a passive state
outside of the active phase.

Resetting to factory settings
The sensor can be reset to the factory setting (one switching point each at 3500 mm or 6000 mm).
Resetting to factory settings
1.When switching on the supply voltage (during power-on), press the teach button for > 5s.
2.Release the button. The green, yellow and blue LEDs flash alternately and very quickly for a brief time.
The sensor was reset to the factory setting:
switching output OUT 1: NO contact, 1 switching point at 3500 mm or 6000 mm (static 1-point teach),
switching output OUT 2: NC contact, 1 switching point at 3500 mm or 6000 mm (static 1-point teach).
