5.5.4 Coding
wenglor light curtains are coded at the factory in order to assure that any given emitter is only capable of influenc-
ing its own corresponding receiver. The coding of the light curtain can be changed during initial start-up. Coding is
initialized as follows:

Alignment-LED and
Failure-LED light up

In order to reset to standard encoding (default status), please proceed as follows:
Same procedure as above, but only press and hold the enter button on the emitter for a duration of 1 to 3 seconds.
The red error indicator must not light up while the enter button is being pressed and held. If the red error indicator
lights up, the enter button has been pressed and held too long.
Alternatively the following procedure can be used:
