## Concept of operation 

Setting the switching threshold (dynamic) 

**1. Position background 2. Move at least the mark and background using the light spot.** 

Press the teach-in button and Keep the teach-in button keep it pressed. LED flashing > 3 < 30 s pressed. slowly. 

Release the teach-in button. 

Yellow LED will illuminate, when emitted light is on the mark.

## **Switching characteristics** 

The optimum emitted light is selected automatically (at RGB variants). Static teach-in: light/dark setting is defined using teach-in sequence. Dynamic teach-in: switching output active on mark, if background is longer in the field of view during the teach-in. The switching threshold is set in the center between the background and the mark. 

If the button is pressed again within 10 s of the teach (> 20 ms < 10 s), the relative switching threshold is placed 75 % between mark (100 %) and background (0 %) (dotted line in Figure). Teach-in can also be performed using an external control signal. 

Keylock activation and deactivation: hold down teach-in button > 30 s. 

Teach-in failure: yellow LED indicator and the transmitted light of the sensor flashing quickly. For dynamic teach-in with ET signal (5 Hz) via switching output Q.
