Replacing the Limit Switch for the End Position Width Adjustment System [00316831-
xx]
Overview
Parts
▪ Limit switch on the assembly tub
▪ Limit switch for width adjustment 1
▪ Limit switch for width adjustment 2
▪ Limit switch for width adjustment - at the conveyor
edge
The microswitch [00316831-xx] is used for all limit switch-
es.

Limit switch in placement area:
There are 2 limit switches below the conveyor sides, in
the placement area. The limit switch is designed to pre-
vent the conveyor edges hitting one another or the con-
veyor base.
Limit switch on the output conveyor:
In the vicinity of the output conveyors, you will find two
limit switches for the adjustment unit. They serve to se-
cure the transport area and to initialize the adjustment
unit during width adjustment.

modular PCB conveyor only)
Overview
► Adjust the conveyor width, so that the required limit
switches can be easily accessed.
NOTICE!
The limit switches are preassembled and include cables.
However, if the limit switch itself is faulty, the wiring can
be unsoldered/soldered right at the switch in question.
Remove the heat-shrinkable sleeves and unsolder the
connection wires on the defective limit switch (1).
Loosen and remove the two screws (2) fastening the de-
fective limit switch.
If you have discovered a break in the connection cable
during a continuity check, this cable must be unthreaded
as far as the conversion board of the assembly tub and
unplugged there.This might be somewhat complicated
depending on the routing of cables inside the machine
base.
You may wish to contact SIPLACE service team regard-
ing this work.
► Fit the new limit switch and re-solder the connection
wires in the correct allocation.
Checking the position of the limit switch:
► Check the minimum and maximum width of the rele-
vant machine type and the parallelism of the convey-
or edges.

Replacing the Cylinder Switch for the Adjustment Unit [03040796-xx] (applicable to
modular PCB conveyor only)
Overview
The cylinder switch 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.
► Move the PCB conveyor to the position which gives
you best access to the adjustment system.
► Move the Y gantries into the area outside the PCB
conveyor.
► Switch off the machine and secure it to prevent unau-
thorized reactivation.
► Switch off the compressed air supply.
► Position the width adjustment belt of the adjustment
unit so that the solenoid valve can be easily ac-
cessed.
► Remove the compressed air connections (2).
► Loosen the two fastening screws and remove the so-
lenoid valve (3) from the short-stroke cylinder.
► Unthread the connection cable (1) as far as the rele-
vant assembly tub conversion board and unplug.
NOTICE!
This might be somewhat complicated depending on the
routing of cables inside the machine base.
You may wish to contact SIPLACE service team regard-
ing this work.
► Fit the new solenoid valve (3) and reconnect the sys-
tem to the electrical (1) and compressed air (2) sup-
plies.
