GENERAL SETUP PROCEDURES
5-4
LABEL SENSOR SETUP
The Label Sensor is a “U”-shaped Optical Sensor that is connected to the sensor electronics with Fiber
Optic Cable. To insure proper operation of the Label Sensor, there should be no sharp bends in the Fiber
Optic Cable from the Sensor to the Applicator Housing. The two sensor forks contain a light emitter and a
receiver. For best accuracy, both surfaces should be kept free of contaminants and the light emitter should
be in the lower fork. The web must be positioned inside the forks of the Sensor so that the Sensor can see
the label surface. The contrast inside the label should be fairly uniform to avoid false edge detects. If the
liner appears within the label, move the Sensor in or out to avoid this area on the label. The Label Sensor
has two detection modes available for instances where the entire leading or trailing edge of the label is
similar in contrast to the label gap. The terms Leading and Trailing Edge refer to the first and second label
edges that the Sensor encounters as the label moves past the Sensor. Select the edge option that gives the
most reliable performance for your particular label.
AUTO SETUP
In Auto Setup, the Applicator will automatically set the Label Sensitivity, Label Length, and Label Stop
values. Also, it will calculate the “Short Feed Distance” if the Multi-Panel Apply Option is enabled prior
to running Auto Setup. Refer to page 3-7 of the Display Section in this Manual. Select whether you want
to sense the leading or trailing edge of the label and follow the instructions there.
MANUAL SETUP
The Manual Setup function is provided for those instances where Auto Setup does not work. Refer to page
3-7 of the Display Section in this Manual for instructions on how to setup the Sensor.
