11.3.6 Setting and checking the laser light barrier for the stopper position
DANGER: Laser class 2
The laser light barrier transmitter emits class 2 laser beams. You do not need
to take additional protective measures!
X You should never look into the laser beam, however.
X 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!
NOTE:
The laser beam deflection has greatest effect at the maximum conveyor width,
it should always be calibrated at the maximum conveyor width.
NOTE:
After setting the laser light barrier you must check or re-teach the PCB
reference corner!

Procedure
X Set the maximum conveyor width.
X Choose General functions --> Cycle mode --> Safety mode switch on.
X Activate the relevant laser diode using the input/output functions in SITEST.
X Check the path of the laser beam by covering the front edge of a board with a white label and moving
it into the placement area.
X With the help of the three setting screws, adjust the laser beam to the center of the receiver.
X Check the PCB reference corner and reteach, if necessary.

NOTE:
When you move the paper, the beam must follow along the edge of the PCB as
accurately as possible, with minimal deflection to the left and right.

11.3.7 Function "Constant Transport Time in Placement Area"
11.3 - 3: Diagrams PCB braking
The automatic teaching at the beginning of the travel profile guarantees that the stopper is always
reached in the same time, irrespective of the board weight. The transport time remains the same.
Function:
Switching on the laser light barrier
Starting the board braking procedure.
The light barrier in the placement area is used to recognize the board and then start the braking
procedure (travel profile) via the conveyor control software. The software automatically "teaches" the first
board how to move in slow approach mode. Once the travel profile for braking the PCB has begun (on
time), the PCB will be reliably stopped at the laser light barrier, after a maximum of 100ms.
