If the teaching was not successful, the procedure must be repeated. Make sure that the
sensor is positioned in the gap between the labels and the subsurface is clean (no
adhesive residues or the like).

LED flashes, setting the type of label (paper or metal).
Each time you press the button it changes the label type.
The configured label type is indicated by the colour of the LED:
green = paper, red = metal
The function ends automatically 10 seconds after the last time the button is released.
> 15s, < 20s
LED is off , adjusting the offset.
After the button is released, a sequence of flashes indicates the offset currently
configured (the default value for paper labels is 6, for metal labels 10).
Then, press the button once briefly = offset + 1 (increase by 1), or
press the button once for a longer time = offset - 1.
As in the beginning, after every change a sequence of flashes will indicate the value
currently set.
The function ends automatically 10 seconds after the last time the button is released.
The offset only needs to be changed in exceptional cases, generally only at speeds of
120m/min or higher. In such cases the gap between the labels may not be detected
reliably and the sensitivity must be adjusted.
Decrease the offset for very thin labels of below 50µm • approx. 2000µin and increase it
for very thick labels of more than 150µm • approx. 6000µin.
Offsets from 1 to 20 can be configured.

LED is on , reset to factory settings.
The factory settings are: paper label, offset 6 (offset 10 for metal labels).
After the end of the function (when you release the button), the system issues a flashing
code
(2 slow flashes).
