## Concept of operation 

Teach-in dynamic via Teach-in button 

## **1. Start teach-in:  Position** 

## **2. End teach-in:** 

## **carrier or label between the fork** 

**==> picture [4 x 4] intentionally omitted <==**

**----- Start of picture text -----**<br>
+<br>**----- End of picture text -----**<br>


Press the teach-in button for 3 - 20 s. With the pushbutton pressed down, move several label with carrier material (label) through the sensor. The yellow LED flashes at 3 Hz during the teach-in procedure. Recommendation: Move at least 3  label + carrier through the sensor. 

Release the teach-in button for < 20 s. If teach-in is successful, the function indicator (yellow LED) directly indicates the output state of the sensor. The switching t hreshold is now optimally set between carrier and label. The best possible operational safety is provided. 

## **Note** 

## **Fine adjustment** 

In order to obtain a higher operating reserve, a fine adjustment can be carried out after successful teach-in. For this purpose, the switching threshold is set close to the taught-in object. The teach-in button must be pressed and released within 10 s of successful teach-in. Successful setting is signaled by flashing twice at 1 Hz. 

## **Light/dark switching** 

You can change between light switching and dark switching by pressing the teach-in button for 20 - 30 s. 

## **Pushbutton lock** 

- The device can be locked against unintended operation by pressing the teach-in button for > 30 s. The device can be unlocked by pressing the teach-in button again for > 30 s.
