7.8 Laser light barriers, fiber optic cable and PCB sensors

268 Service Manual SIPLACE X-Serie S 06/2019

Overview

Fig.337: Overview of conveyor controls

The cables for the laser light barriers are

either connected directly to the conveyor

controls(1) or to the input or output area(2)

of the conveyor.

For details of the conveyor control, see

7.9.1.1 "Conveyor control TSP420" [}291].

Removal

► Switch off the machine, disconnect it from the power supply and secure it to prevent

unauthorized reactivation.

1.2 "Preparatory work..." [}16]

CAUTION

Move the conveyor sides carefully!

The clamping and guide rails are a key stabilizing element for the conveyor side, which is

then less stable once they have been removed.

► Move the opened conveyor sides very carefully.

► Make sure that the sides are always pushed equally on the left and right.

► Make sure that you do not distort the sides.

CAUTION

Make a note of the order in which the cables are run!

The room in the side walls is limited. Therefore, make sure that no cables are crossed over,

particularly in the output area, from the trailing cable to the laser light barrier.

Make a note of the order in which the cables are run in the side panel, so that you can run

them neatly and correctly again later on.

► Remove the transmitter/receiver.

7.8.1 "Replacing the Laser Light Barrier for the Transmitter/Receiver" [}263]

► You might need to dismantle other guide rails in order to thread the cable out of the conveyor

side, as far as the trailing cable.

7.7.3 "Replacing the Clamping Rail/Belt Guidance" [}259]

► You might want to move hexagonal shafts in order to create more room for movement.

Fig.338: Holding plate

► Remove the screws(2) fastening the

bracket(3) to the top end of the trailing

cable(1) on the conveyor side.

► For better access, you can remove the

screws fastening the trailing cable to

the bracket.

Fig.339: Cover plates (example of SX1/SX2 shown)

► In the intermediate conveyor: dismantle

the two cover plates(1) and (2) under

the trailing cable. To do this, loosen the

four fastening screws for each and then

remove the cover plates.

Fig.340: Opened trailing cable

► Open the trailing cable.

 NOTICE!

There is also a protective tape in the

trailing cable. This separates the fiber

optic cable from the cables.

 CAUTION!

Make sure you do not bend the fiber

optic cable. These could otherwise be-

come cloudy or break and no longer

transmit the signal properly.

► For better access, you can remove the

screws fastening the trailing cable to

the bottom of the conveyor.

► Thread the cable out of the conveyor

side and the trailing cable.

Fig.341: Connections (here output conveyor location 3)

► Disconnect the cable. You may want to

mark the position, to make clear as-

signment easier later on.

Installation

► Follow the removal instructions in reverse order for installation. Also observe the following

instructions:

– Leave enough room at the cable for easy removal of the transmitter/receiver from the side

wall. Make sure that the connector is not directly under the housing, otherwise you might

have problems inserting the module.

– Replace any open cable ties.

Make sure that the cable ties and the heads of the cable ties do not rub against any parts

when you do this.

– Check the setting for the transmitter/receiver and correct if necessary.

– Teach the PCB sensors.

7.8.3 Checking the laser light barrier

Whenever the laser light barrier is dismantled, it then needs to be checked and manually set again,

if necessary. Check the setting as follows:

Fig.342: Select operator level

► Select the

button, to open the

Configure, update and calibrate the

machine menu.

► Select the

button to open the

Check and set user settings menu.

► Switch over to the operator level Ma-

chine service.
