4.6.2 Correcting the laser light barrier setting
DANGER
Laser Class 2
The laser light barrier transmitter emits class 2 laser beams. You therefore do not require
additional protective measures!
► However, you should never look into the laser beam.
► Adjust the laser beam only from the rear side of the laser!

Procedure with setting gauge
Fig.62: Focusing the laser beam (using example of X-Series)
1. Setting the laser light barrier
2. Minimum width
3. Maximum width
► Set the maximum conveyor width.
► Select Enable safety mode in software.
► Activate the relevant laser diode using the input/
output functions in the station software.
► Check the path of the laser beam with the help of
the gauge.
► With the help of the three setting screws, adjust
the laser beam to the center of the gauge cross
(1).
► Now position the conveyor to minimum width(2)
and check the setting.
► Check the PCB reference corner and reteach, if
necessary.

4.6.3 Repairing the fiber optic cables
To avoid machine downtimes, it is possible to repair fiber optic cables temporarily, using the repair
hose.
NOTICE
Repair hose for fiber optic cable LL3-TV05
► The repair hose may only be used for short periods to avoid machine downtimes.
► The repair hose may only be used once per fiber optic cable.
► The fiber optic cable must be replaced during the next repair or maintenance cycle.
NOTICE
No guarantee
► No guarantee is given if the fiber optic cable is repaired using the repair hose.
► There is no long-term experience with the repair hose.
► Depending on the board width, the intensity of the light beam may diminish in such a
way that an evaluation is no longer possible.
► The repair hose must not be bended. For this reason, there is an additional danger of
rupture after the repair, in areas where the fiber optic cable is routed in narrow radii.
► If another rupture of the fiber optic cable occurs and it is not possible to replace the whole
fiber optic cable, replace the defective part of the fiber optic cable in such a way that only one
repair hose is used.
