Concept of operation

Teach-in dynamic via Teach-in button

Note

Light/dark switching

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.

+

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.

2. End teach-in:

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.

1. Start teach-in: Position

carrier or label between

the fork
