## Concept of operation 

Teach-in via plus/minus buttons (WFxx-B416) 

## **The switching threshold is set automatically. Fine adjustment is possible using the “+”/“–” buttons.** 

## **1. No object or substrate in** 

## **the beam path** 

## **2. Object or label in the beam path** 

Press the “+” and “–” buttons together and hold for 1 second. The red function indicator flashes slowly.

**----- Start of picture text -----**<br>
Press the “–” button for<br>1 second.<br>Red function indicator goes out.<br>**----- End of picture text -----**<br>


## **Notes** 

Material speed = 0 (machine at a standstill). 

Once teach-in process is complete, the switching threshold can be adjusted at any time using the “+” or “–” button. To make minor adjustments, press the “+” or “–” button once. To configure settings quickly, keep the “+” or “–” button pressed for longer. 

- Press both the “+” and “–” buttons together (3 seconds) to lock the device and prevent unintentional actuation. 

- Press both the “+” and “–” buttons together (6 seconds) to define the switching function (light/dark switching). Standard setting: Q = light switching.
