Setting the label sensor
The ALS 104's label sensor is preset for use with stand-
ard label material. For low-contrast labelling material, it
may be necessary to adjust the setting.
Wenglor sensor
Tools:
– Adjustment screwdriver [37]
(Order no. A7634)
Insert the adjustment screwdriver [37B] through the
hole [37A] next to the power switch unit to access
the adjusting screw of the potentiometer.
Place backing paper in the fork of the photoelectric
sensor.
Turn the adjusting screw
anticlockwise
until the LED
on the photoelectric sensor lights up.
Turn the adjusting screw
clockwise
to just beyond
the point where the LED goes out.
Place label material in the fork of the photoelectric
sensor. The LED will light back up.

beyond the point where the LED goes out. While do-
ing so, count the number of turns required.

Avery sensor
Press the button [38A] for 2 s, until the status LEDs
[38B] light permanently.
– After releasing the button, a teaching „time window“
opens for 2-8 s. During this period, the status LEDs
are flashing fast [39].
While the LEDs are flashing, move as many labels
as possible (at least 2) through the sensor fork.
– This has to be done manually,
not
by pressing the
button.
– If the labels were detected successfully, the status
LEDs are flashing 2x.
– If the labels were not detected ideal, the status
LEDs are flashing 4x.
Repeat the procedure, if the labels were not detect-
ed ideal.
