Adjusting the switching behavior of the switching output – light/dark switching

Press teach button until the green LED flashes. The yellow LED displays the current setting ofthe switching output:ON = output switches on lightOFF = output switches on dark

Continue to press the teach button in order tochange the switching behavior.


Locking the teach button via the teach input

A static high signal (≥ 4ms) at the teach input locks the teach button on the device if required, such that no manual operation is possible (e.g., protection from erroneous operation or manipulation).

If the teach input is not connected or if there is a static low signal, the button is unlocked and can be operated freely.

Sensor adjustment (teach) via teach input

The following description applies to PNP switching logic!

UTeach low ≤ 2V

UTeach high ≥ (UB-2V)

Prior to teaching: Clear the light path to the reflector!

The device setting is stored in a fail-safe way. A reconfiguration following voltage interruption or switch-off is thus not required.
