6.5.10 Board Clamping Functions Conveyor
Service Manual SIPLACE D4/D4i 237
► The clamping actuators are delivered with a basic setting of 94.2 mm to the top edge of the conveyor
belt.
► If problems occur during board clamping (board partially or fully loose), you will need to reset the
clamp.
The cause of this problem is that there are a total of six actuators on three conveyor edges. If these
are not set accurately enough (they do not form a level), up to three actuators might have been set
incorrectly. These then need to be adjusted.
Procedure
A) Checking the clamping play:
► Move the lifting table upwards, without the board.
► With the aid of a 0.1 mm feeler gauge, check the gap between the conveyor belt and the clamp (see
graphic above).
If the gap is larger than 0.1 mm, the distance determined between the belt and clamping edge on the
actuator will need to be reset.
To do this, you need to add the current distance between the actuator and the clamping plate to the
distance between the belt and the clamping edge!
► Move the lifting table down again.
(1) Conveyor belt play on the lower edge of the
clamp
(2) Distance 94.2 mm.
NOTICE
Play between the terminal strip and the upper edge of the conveyor belt
The play between the terminal strip and the upper edge of the conveyor belt may not be more
than 0.1 mm.

B) Setting the play on the actuator:
► Disable the clamp and move the lifting table down.
► Measure the play between the actuator and the side edge with a feeler gauge.
► Loosen the actuator screws.
► Set the distance again with the help of a feeler gauge.
Add the play for the clamp to the play for the actuator.
► Tighten the actuator screws again.
► You now need to recheck the gap between the conveyor belt and the clamp when the lifting table
has moved up. (see above)
► If a problem occurs during board clamping, recheck this setting again. We recommend that you
check this setting every three months. When cleaning the machine, always make sure that you re-
move all components from the conveyor belt.

Adjusting the Speed of the Lifting Table (from SW 602)
Time needed to move lifting table up with lifting table plate
► Switch the machine on and start the SITEST program.
► In the PCB conveyor functions menu (see adjacent diagram) you can see the travel time for the lifting
table (from SW 602 upwards).
► Click on Actuate Clamp.
Time needed to move lifting table down with lifting table plate
► The lifting table will be moved up and the travel time will be displayed (see diagram).
► Press the Actuate Clamp button again to move the lifting table downwards and to view the travel time
for the downwards movement.
► If the travel times are not inside the tolerance range or if error messages appear during production,
adjust the travel times (displayed since SITEST 60x) as follows:
► Adjust the valve on the lifting table cylinder, so that you get the following values:
