Procedure with setting gauge
Fig.130: 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 soft-
ware.
► 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.
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.

Troubleshooting
► In the station software, activate all fiber optic cables (transmitters). These may need to be re-cal-
ibrated without boards in the conveyor.
► A red light must be visible for the transmitters.
If no light is visible at the transmitter, there is probably an error.
► As a cross-check, you can switch the transmitting and receiving fiber optic cable at the corres-
ponding fiber optic sensor (WLL180T-F preconfigured SXa [03093295‑xx] or WLL180T-M pre-
configured SXa [03093294‑xx]).
NOTICE
Do not confuse the transmitter with the receiver
► Make sure not to confuse the transmitting and receiving fiber optic cable. If you do, other optical
sensors may be sporadically affected.
NOTICE
Display on the fiber optic sensors
The display on the fiber optic sensors corresponds to the currently measured intensity.
► The intensity can vary depending on installation position, cable length and environmental condi-
tions.
► The value shown should be not less than 100.
► The fiber optic sensor reacts to intensity deviations during operation.
Performing the repair
► Use the software or manually move the conveyor rail into a position which allows you best
access.
To move the conveyor side wall manually, pull the toothed belt of the width adjustment unit.
► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthorized
reactivation.
► Remove the fiber optic cable from the conveyor side.

NOTICE
Sticker
If the fiber optic cable has already been repaired, a yellow adhesive sticker dot will be attached to the
optical system or the fiber optic sensor.
One repair hose may be used per fiber optic cable. You must either replace the whole fiber optic
cable or the part that has already been repaired.
► Check the fiber optic cable for damages.
The most common error causes are:
– Optical system of the fiber optic cable damaged
– Fiber optic cable pinched in conveyor side
– Fiber optic cable ruptured (e.g. caused by a too narrow bending radius)
NOTICE
Fiber optic cable ruptured at the trailing chain
If the fiber optic cable is ruptured in the trailing chain or at the transition from the trailing chain to the
conveyor side, the effort for finding the error cause is often identical to the effort for replacing the
complete fiber optic cable.
► Cut the fiber optic cable at the defective position.
► Use the cutter tool to cut off 10mm of the fiber optic cable on each side of the rupture.
Make sure to preserve a minimum distance of approx. 50mm to the optical system of the fiber
optic cable.

CAUTION!
Only use each cutter opening once
Make sure that each cutter opening is
only used once. The quality of the cut
cannot be guaranteed if it is used more
than once.

Fig.132: Repairing the fiber optic cables
► Slide both ends of the fiber optic cable into
the repair hose until they touch each other.
► Fix the repair hose into place with Loctite
406.
This adhesive is used to fix the fiber optic
cable in the hose. The two ends of the
fiber optic cable are not fixed to one
another with adhesive.
CAUTION!
Highly viscous instant glue
Use gloves and a dosage tip.
