Positioning the sensor holder:
The sensor holder be varied in a wide range on the hol-
ding rods. The most favorable position can be found as
follows:
– Label web is in stop position (position just after dis-
pensing a label).

Push the sensor holder over a label gap and fix it
there.
– In this position should be possibly few labels bet-
ween dispensing edge and (capacitive) sensor.
– Fine adjustment of the stop position is done in the
same way as with the standard label sensor.
Leuze sensor setting
:

Remove label material from the sensor fork.

Turn potentiometer [72B] to the right, until a light
click is audible (= max. sensitivity). Turn the
potentiometer
½
turn to the left.

Turn potentiometer [72D] until both LEDs [72C]
shine equally bright (= base adjustment).

Move the label web through the sensor fork and
watch the switching output LED.
– The LED [72C] must shine in label gaps.

If case of insufficient switching behaviour, change
the sensitivity setting.

After increasing the sensitivity setting, the base
adjustment must be repeated.

Di-Soric sensor setting:

Insert label material into the sensor fork.
– The label material must lie on the bottom fork arm
[73D].

yellow] lights up (approx. 2 s).
– The mode LED starts to flash quickly for approx.
2-4 s.

During the mode LED flashes, move at least two
labels through the sensor fork.
Service and mode LEDs are flashing…
– 2x: The auto-teach procedure has been concluded
sucessfully. The service LED lights green.
– 4x: The label was not detected optimally, the best
possible switching point will be set. The service LED
lights red.
