LABEL•EYE AUTOSET
Set-Up Instructions
Normal Label Opacity Autoset Button
This category includes most paper or melallized film labels adhering to paper or
transparent backing materials.
To implement the one button Autoset routine, utilize the external alignment guides to
position the gap between labels in line with the dot shown in the center of the detection
zone. Then push the Autoset button marked "Normal".
An alternative set up procedure would be to remove a label and the push
the "Normal" Autoset button.
HINT: If the location of the sensor is several labels up-stream from the peeler plate,
removing just one label will result in applying two labels onto one product and one
product receiving no label what so-ever. This is why we recommend setting up the
sensor with the actual "gap" between the labels properly positioned.
On rare occasions, when the light is unable to penetrate the backing materials, both
the red and green led indicators will blink four times. When this indication occurs, the
sensor will be unable to detect the presence of the labels.
Translucent Label Opacity Autoset Button
This category includes translucent labels adhering to transparent backing materials.
This sensor cannot detect transparent labels adhering to transparent backing
materials. The question is how close to transparent can the translucent labels be and
still be detected? There is no definitive answer to that question. To determine if detection
of a translucent label adhering to transparent backing material is to try the following
Autoset procedure. First utilize the external alignment guides to position the gap
between labels in line with the dot shown in the center of the detection zone. Then
push the Autoset button marked "Translucent". The next step is to move the web so that
the translucent label goes in and out of the light beam. If detection is possible, the red
led output indicator should go on when the label passes through the detection zone.
INVERT OUTPUT: The status of the red led and output transistors can be inverted by
pressing both buttons simultaneously. When the output status has been inverted, the
red led and the output transistors will turn off when the label comes into view.
