Legend

➠ This setting must be repeated for all the conveyor rails.

9.2.5.2 Setting the ’pneumatic cylinder BERO’ on the driver

The BERO (3) (see Fig. 9.2 - 9) on the driver cylinder is designed to switch when the pin of the

driver is extended by the pneumatic cylinder so that the conveyor rail is engaged. This signal en-

ables the width adjustment motor.

Procedure: 9

Please Note:

The BERO on the pneumatic cylinder is set in the engaged state (but not in the free space!).

➠ Start SITEST

➠ Set any conveyor width. This moves the drivers directly under the conveyor rail.

➠ Start the I/O menu.

➠ Activate the pneumatic cylinder.

➠ Set the BERO on the pneumatic cylinder so that the LED (H35/H36/H37 TSP 301) lights up in

the engaged state (see Fig. 9.2 - 9).

9.2.6 Setting and checking the laser light barrier for the stopper position

Danger:

Laser beams of laser class 2 occur at the laser light barrier transmitters, so no additional protective

measures are required.

You should never look into the laser beam, however.

Do the adjustment of the LASER Diode Beam direction only from the rear side of the LASER (left

machine side). Keep right side machine covers closed!

The laser beam deflection has greatest effect at the maximum conveyor width, it should always

be calibrated at the maximum conveyor width.

Please Note:

Check or reteach the PCB reference corner after adjustment of the laser light barrier!

Fig. 9.2 - 11 Laser light barrier

Procedure:

➠ Set the maximum conveyor width.

➠ Choose General functions --> Cycle mode --> Safety mode switch on.

➠ Activate the relevant laser diode using the input/output functions in SITEST.

➠ Check the course of the laser beam. You can make the laser beam visible using a light-colored

PCB or a white sheet of paper (see Fig. 9.2 - 12).

➠ If necessary, use the adjusting screws to set the laser beam to the center of the receiver.

➠ Check the PCB reference corner and reteach, if necessary.

Please Note:

When you move the paper, the beam must follow along the edge of the PCB as accurately as pos-

sible, with minimal deflection to the left and right.

9.2.7 Setting the light barrier in the placement area

Function: 9

– Switching on the laser light barrier

– Starting the PCB braking, see Fig. 9.2 - 13.

The light barrier in the placement area can be mounted in three different positions. The light barrier

is fitted in the direction to the input conveyer. The light barrier then trigger the LASER stopper and

slow down the PCB movement. The

slow PCB approach is teached automatically via soft-

ware.The travel profile for braking the PCB (see Fig. 9.2 - 13) is started in good time to allow the

PCB to be stopped reliably at the laser light barrier after no more than 100 ms.
