Chapter 7 Adjustment and initial operation
Insert label roll in labeler
Detailed information on adjustment of the labeler is described separately in provided
manual!
Additionally there is a threading pattern sticked on each labeler that shows the guiding of
the label web. Thread the label web accordingly. Please observe that for each labeler and
the product to be labeled, there will be inserted the correct label roll.
Adjust product light barrier
One or more light barriers are used for detection of the product at the labeler. If a product
is detected, a signal is forwarded to the controller to start for example an assembly group
or the labeling process. The point of time of the product detection is significant for the
positioning of the label onto the product.
To position the label more backwards onto the product, the light barrier could be moved to
the rear. Labelers with display controller offer the opportunity to process the input signal of
the light barrier after a programmable delay. In case of this variant an adjustment of the
light barrier is not required. It is even undesirable!
Labeling systems without programmable delay provide an easy adjustment. The light
barrier is mounted on a movable bracket (cp. Pos. 2, Fig. 7-3).

Depending on product feature an adjustment of sensor sensitivity is necessary. Especially
in case of bright and transparent products (e.g. foils) require an accurate adjustment of
the sensor. Further information on adjustment please refer to the manual of the sensor's
manufacturer.
