10.3.3 Light Barrier Functions in Input, Output and Intermediate Conveyors
Boards are recognized reliably and stopped
Boards are monitored in the input conveyor, meaning that
If a board is recognized in the input conveyor, it will appear on the user interface and the machine
will stop the conveyor interface to the predecessor station. When using boards with cutouts, although
the board stops, the light barrier may sometimes be deactivated again and the interface to the
predecessor station reopened. In this case, the next PCB would be transported onto the board
already lying on the input conveyor. To prevent this, the board monitoring system moves the new
board backwards again and then forwards until the light barrier switches.

10.3.4 Board Recognition - Function
Functional description:
The board moves into the placement area, is recognized by the light barrier and stopped at the laser,
before the lifting table moves upwards.
PCB clamping check: The conveyor motor in the placement area is restarted. If the board is clamped
into place, the motor current will exceed a certain value. If the board was correctly clamped, the
placement process will begin.
If the threshold value is not reached, the system will assume that the board has moved towards the
intermediate or output conveyor and has therefore not been clamped correctly into place.
The station computer will issue the error message "Board not clamped correctly PA1 (PA2)". The
operator can try the procedure again by pressing the START button.
The lifting table will move down again, the board will be conveyed back and will approach the stopper
position once more.
NOTE:
The check to see whether a board has been correctly clamped into place is performed by adding
together the conveyor motor currents during a defined period. To check whether this function is
performed correctly, place a spacer under the side to prevent the lifting table moving upwards.
This check is not performed if the "Vacuum Tooling" option is installed.
