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 ef-
fort 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.307: 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 Loc-
tite 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.
.
Further installation is performed by following the above instructions in the reverse order. Also
observe the following instructions:
► Check the setting for the transmitter/receiver and correct if necessary.
7.8.3 "Checking the laser light barrier" [}222]
7.8.4 "Correcting the Laser Light Barrier Setting" [}225]
► Calibrate the sensors of the PCB conveyor.
► Check the display on the fiber optic sensor. The value shown must be over 100. Check the
value for the various conveyor widths (red = output / green = input).
► Mark the optical system and the fiber optic cable at the fiber optic sensor with the glue dot
supplied. The glue dot indicates that the fiber optic cable has already been repaired and that a
replacement is compulsory at the next defect.

Overview
Fig.308: Overview of fiber optic cable sensor
The fiber optic cable sensors are located at
locations 1 and 4, under the covers of the
conveyor control(1)
and(2).
The sensors for the input conveyor, place-
ment area 1 and intermediate conveyor can
be found at (1)
.
The sensors for placement area 2 and the
output conveyor can be found at (2)
.
The fiber optic cable sensors are separated
into master (M) and slave (F).
The receiver is always at the top of the
sensors and the transmitter at the bottom.
The transmitters are located on sides B and D.
The receivers are located on sides A and C.

The master synchronizes the slaves to prevent any mutual interference. This is conducted via a side
connection to the neighboring sensor. For this reason, do not simply lift the sensors up and off the strip.
Each sensor has two fiber optic cables connected (transmitter/receiver), which belong to the same
conveyor belt (segment).

Removal
CAUTION
Do not bend the fiber optic cable
► Make sure you do not bend the fiber optic cable. These will otherwise become cloudy
and no longer transmit the signal properly.
► Use the software to move the conveyor sides into a position which allows you best access. As
an alternative, you can loosen the clamps for the relevant sides in dual conveyors.
7.2 "Loosening the Conveyor Side Clamps" [}162]
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
1.2 "Preparatory work..." [}16]
► Dismantle the cover on the fiber optic sensors.
Fig.310: Fiber optic cable sensors
The individual sensors are connected to one
another via a small terminal strip. Dismantle
the sensors one after one, beginning with
(1)
, until you have reached the sensor to be
replaced. Perform the following tasks at
each sensor:
► Open the cover.
► Open the lock on the fiber optic cables and then unplug the fiber optic cables. You may want
to mark their positions, to make clear assignment easier later on.
► Disconnect from the power supply. You may want to mark the position of this connection to
make clear assignment easier later on.
► Pull the sensor slightly away from the other sensors. Now you can pull the sensor up and off
the strip.
► Repeat these steps if needed for any other sensors.
Installation
Installation is performed by following the above instructions in the reverse order. Also observe the
following instructions:
► Check the setting on the fiber optic sensor and correct if necessary. (See 7.8.8 "Setting the
fiber optic sensor" [}235])
New sensors are preset.
► Remove the plastic cover for the sensor on the side press-fit connections, if needed.
NOTICE
End stops
The fiber optic cable sensors are held at both ends by end stops. If these end stops are
missing or are defective, this can lead to loose connections.
► Replace the end stops when needed.
► Teach the PCB sensors.
