6.5.5.2 Setting the Pneumatic Cylinder Proximity Switch on the Adjustment Unit

X Start SITEST

X Set any conveyor width. The adjustment units are positioned directly under the conveyor side.

X Start the I/O menu.

X Activate the pneumatic cylinder.

X 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.

"locking pin up" recognition)

4. Proximity switch for adjustment unit (for

conveyor side recognition)

 The proximity switch (3) on the adjustment unit

cylinder should operate when the adjustment

unit pin is pushed out by the pneumatic

cylinder and therefore connected to the

conveyor side. This signal enables the width

adjustment motor.

NOTE:

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!

X You should still never look into the laser beam.

X Adjust the LASER diode bean direction only from the rear side of the LASER (left machine

side).

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!

Conveyor Setting the Laser Light Barrier for the Stopper Position

252 Service Manual SIPLACE D4

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.

Function "Constant Transport Time in Placement Area" Conveyor

Service Manual SIPLACE D4

6.5.7 Function "Constant Transport Time in Placement Area"

6-37: Diagrams of 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.
