Setting the Proximity Switch on the Adjustment Unit
► When installing the proximity switch, make sure that this is level with the adjustment unit housing.
► The switching point is set via the actuator on the conveyor edge.
► Move the adjustment unit under the conveyor edge, then loosen the actuator using the screw.
► Place the distance gauge 0.2 mm on the adjustment unit, press the actuator against the gauge and
fix with the screw.
► Check the actuators on all conveyor edges and adjust where necessary.
► You then need to calibrate the conveyor edges with the software.
Limit /initialize switch
NOTICE!
This setting is only required after replacing the switch or
other error functions in the width adjustment reference
run.
► Move the adjustment unit for the width adjustment by
hand (via the toothed belt) to the conveyor edge.
► Loosen the two screws on the limit switch (1).
► Move the limit switch in the slot towards the adjust-
ment unit and make sure, that the limit switch is safely
switched on.
► Check the switching state of the corresponding LED
(H11 for TSP 201) (H41 for TSP 301) in the conveyor
control software.
► Fit the limit switch in this position.
► Calibrate the conveyor width via the SITEST pro-
gram.

▪ The proximity switch (3) serves as a signal for con-
trolling the pneumatic valve of the adjustment unit.
Once the switching point "conveyor edge present"
has been reached, the conveyor edge is connected
via the pneumatic valve.

6.5.5.2 Setting the Pneumatic Cylinder Proximity Switch on the Adjustment Unit
Setting the Pneumatic Cylinder Proximity Switch on the Adjustment Unit
► Start SITEST
► Set any conveyor width. The adjustment units are positioned directly under the conveyor edge.
► Start the I/O menu.
► Activate the pneumatic cylinder.
► Set the proximity switch on the pneumatic cylinder so that the LED (H35/H37 for TSP 301) (H64/65
for TSP 201) shines when connected.

▪ The proximity switch (3) on the adjustment unit cylin-
der should operate when the adjustment unit pin is
pushed out by the pneumatic cylinder and therefore
connected to the conveyor edge. This signal enables
the width adjustment motor.
NOTICE! The proximity switch on the pneumatic
cylinder is set in its engaged state.The proximity switch is
off when the cylinder extended into free space.
DANGER
Laser class 2
The laser light barrier transmitter emits class 2 laser beams. You do not need to take additional
protective measures!
► You should still never look into the laser beam.
► Adjust the LASER diode bean direction only from the rear side of the LASER (left machine
side).
NOTICE
The laser beam deflection has greatest effect at the maximum conveyor width, it should always
be calibrated at the maximum conveyor width.
NOTICE
After setting the laser light barrier you must check or re-teach the PCB reference corner!

Conveyor 6.5.6 Setting the Laser Light Barrier for the Stopper Position
232 Service Manual SIPLACE D4/D4i
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 path of the laser beam by covering the front edge of a board with a white label and moving
it into the placement area.
► With the help of the three setting screws, adjust the laser beam to the center of the receiver.
► Check the PCB reference corner and reteach, if necessary.

NOTICE
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.
