Handling narrow labels
13
The distance between the markings of the
ultrasonic and optical detection pro-
cesses is 14 mm.
For reliable and successful teaching, labels that are not wider than 14-18 mm
should only be guided under one of the two available markings,
ultrasonic or opti-
cal. This eliminates the risk that the labels are only partially detected with both de-
tection processes while teaching, thereby causing errors.
The decision as to which detection process should be used to detect a narrow la-
bel must be made by the operator himself in this case and the label positioned un-
der the marking for the desired detection process on the sensor.
easy Teach with the
ultrasonic detection process
If the label to be detected is guided only under the marking for the
ultrasonic de-
tection process while marking for the
optical detection process remains free, the
teach event during
easy Teach is ended automatically.
easy Teach with the
optical detection process
If the label to be detected is guided only under the marking for the
optical detec-
tion process while the marking for the
ultrasonic detection process remains free,
the teach event during
easy Teach is ended manually by again briefly pressing the
teach button.
As soon as the sensor has determined sufficient teach values, the yellow PA-
PER LED illuminates to indicate to the user that the teach button can be pressed
to end the event.
NOTICE
In this case, the sensor does not indicate the transport of the label tape
through alternating rapid flashing of the green ON LED and the yellow
OUT LED.
