7.6.5 Replacing the Fiber Optic Cable Sensor

Parts, equipment and tools

●

Fiber optic sensor WLL180T-M pre-programmed SXa [03093294-xx] (master) or

Fiber optic sensor WLL180T-F pre-programmed SXa [03093295-xx] (slave)

Overview

Fig.235: Fiber optic cable sensors

The fiber optic cable sensors are located at location 2

under the lifting table plate.

The sensors (1) to (8) for the input conveyor, place-

ment area (second sensor as option) and output area.

The receiver is always at the top of the sensors and

the transmitter at the bottom.

Conveyor lane Designation Location

Lane 1 1 (master) Input belt

2 (slave) Placement area

3 (slave) Second sensor as option

4 (slave) Output belt

Lane 2 5 (slave) Input belt

6 (slave) Placement area

7 (slave) Second sensor as option

8 (slave) Output belt

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. Otherwise the cable will become

cloudy and no longer transmit the signal properly.

► Use the software or manually move the conveyor rail into a position which allows you best ac-

cess.

– To move the conveyor rail 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. Observe the instructions in section 1.2 "Preparatory Work..." [}15].

► Move all gantries out of the transport area as far as possible at one side of the machine.

► Dismantle the cover on the fiber optic sensors.

Fig.237: Fiber optic cable sensors

The individual sensors are connected to one another

via a small terminal strip.

Dismantle the row after the sensors, beginning with (8)

(lane2, output belt) until you have reached the sensor

to be replaced. Perform the following tasks at each

sensor:

► Open the cover(1) on the sensor.

► Open the lock(2) on the fiber optic cables(3) and

then pull off the fiber optic cables. You might like

to mark their positions to make clear assignment

easier later on.

► Disconnect from the power supply(4). You may

want to mark the position, to make clear assign-

ment easier later on.

► Pull the sensor slightly away from the other

sensors, to loosen the electrical connection to the

neighboring sensor. Now you can pull the sensor

up and off the strip.

► Repeat these steps if needed for any other

sensors.

Installation

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

structions:

CAUTION

Installation instructions

► Check the setting on the fiber optic sensor and correct if necessary (see following sec-

tion).

New sensors are preset.

► Remove the plastic cover for the sensor on the side press-fit connections, if needed.

► Teach the PCB sensors.
