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.
Press the “–” button for
1 second.
Red function indicator goes out.
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.
