X If necessary, correct the mechanical position of the limit switch and repeat the measurement

procedure.

X If the value is within the permissible limits, save the data by clicking on

X Seal the two mounting bracket fastening screws with locking varnish.

3.6.8 Replacing the Collision Light Barriers [03047281-xx]

Overview

1. Collision light barrier for normal components

(receiver) with LED

2. Collision light barrier for normal components

(transmitter)

3. Collision light barrier for high components

(transmitter)

4. Collision light barrier for high components

(receiver) with LED

Spare parts

 Collision LB for normal components

[03047281-01]

 Collision LB for high components [03047282-

01]

NOTE: Transmitter and receiver

together as one spare part

The transmitter and receiver of the

relevant collision light barrier are

stocked as one spare part with one part

number.

X Depending on the error occurring,

you may need to replace the

transmitter and receiver together.

3.6.8.1 Adjusting the Collision Light Barriers

X Loosen the two fastening screws (1) for the

relevant sensor (transmitter or receiver) on the

mounting bracket (2).

X Loosen the two screws holding the cable

fixtures (3).

X You need to remove the plastic guidance on

the right-hand side, so that you can unthread

the plug or light barrier.

X Loosen the cable clamps and remove the

cable ties.

X Unthread the connection cable as far as the

control unit back plane and unplug it from the

terminal strip.

X Fit the sensor on the mounting bracket (2).

X Align the sensor parallel to the mounting

bracket (3).

X Restore the electrical connection and fix the

connection cable into place.

2. Setting gauge large for collision lightbarriers

[03051814-01]

3. Step for passage height of "normal"

components in case that every level of the

WPC is used.

4. Step for trigger height of collision light barrier

for "normal" components

5. Step for passage height for "high" components

if the subsequent level above is not used.

6. Step for trigger height of collision lightbarrier

for "high" components

The status of the collision lightbarrier is displayed at the integrated LED

 Red LED ON = not triggered (normal mode)

 Red LED OFF = triggered (light beam is interrupted - collision situation)

 Green LED ON = ready for operation/stability display (optimum light barrier setting)

 Green LED OFF = ready for operation/stability display (no optimum light barrier setting)

X For the setting of the collision lightbarriers the large setting gauge (2) is needed.

Step 1: Height setting

X Put the setting gauge with the step for passage height on the WPTC in front of the corresponding

sender/receiver.

 The green and the red LEDs must be ON.

X Move the gauge or the WPTC to the trigger height step.

X Check whether at the trigger height step the light beam is now interrupted:

 The red LED must be OFF.

X If the setting is not correct the height of the sender or receiver at position (4) and (6) resp. (7) and

(8) must be corrected.

X Put the setting gauge with the step for trigger height on the WPTC in front of the corresponding

sender/receiver. The collision lightbarrier must definitely trigger here, too.

X Repeat the described procedure until the collision lightbarrier is adjusted to the correct height and

switches at the trigger points over the whole width of the WPTC.

Step 2: Functional check in SITEST

X Additionally check in SITEST if the correct outputs are switched.

 In the SITEST main menue in

Function => SITEST Inputs-/Outputs

the display

collision

lightbarrier for normal components

collision lightbarrier for high components

will be

activated.

Measurement setup and procedure

1. Waffle pack tray carrier (WPTC)

2. Setting gauge

3. Passage height (for high components)

4. Setting of collision lightbarrier (receiver) for

high components

5. Step for trigger height of collision lightbarrier

for "high" components

6. Setting of collision lightbarrier (sender) for high

components

7. Setting of collision lightbarrier (receiver) for

normal components

8. Setting of collision lightbarrier (sender) for

normal components

NOTE:

X The settings must be set on both sides of the WPTC.

X Check the function in SITEST (Step 2)
