The optoelectronic label sensor of the HERMA 500 unit is used for contact-free detection of non-transparent
labels on any backing paper. The unit is set up so that label gaps can be quickly identified with extreme precision.
The yellow LED is used for display, which means it lights up when the gap between the labels is detected and
goes out when a label is detected.
Positioning the sensor at a right angle to the direction of label movement
 Loosen knurled nut 3.
 Move the scanning spot of the light barrier 4 (see marking) to the centre of the label while the label web is
moving.
 In case of round labels the scanning spot should be positioned over the label centreline.
