CAUTION! Do not damage the toothed belt!
During the following removal and installation of the motor,
the toothed belt for the width adjustment drive must not
be stretched or kinked!
► Move the PCB conveyor to the position which gives
you best access to the stepping motor of the width
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.

► Loosen the screws fastening the lifting table plate and
remove the lifting table plate from the lifting table unit.
► Loosen the eccentric axis (1) on the deflection pulley
and relieve the tension on the drive toothed belt (5).
CAUTION! Toothed belt must not come off!
When relaxing the toothed belt, make sure the belt does
not come off (skip) the toothed disks at the 3 adjustment
units. This would cause incorrect alignment of the adjust-
ment units. Secure these positions with a suitable tool
(screw clamp etc.)
► Remove the 4 fastening screws (3) and then lift out
the stepping motor (4).
► Unplug the connection cable in the cable duct.
► Fit the new stepping motor and reconnect the system
to the electrical system.
► Tension the drive toothed belt.
Position the measuring point of the belt tension de-
vice at the strand center (i.e. the longest distance be-
tween two toothed disks) of the conveyor toothed
belt.
► Set the tension of the drive toothed belt according to
the following values.

Parts
▪ Limit switch on the assembly tray [00365002-xx]
▪ Limit switch for width adjustment 1 [00365108-xx]
▪ Limit switch for width adjustment 2 [00365109-xx]
▪ Limit switch for width adjustment - on the conveyor side [00362345-xx]

Limit switch on the input conveyor:
In the vicinity of the input conveyor there are 4 limit
switches under the conveyor sides. The limit switch is de-
signed to prevent the conveyor sides hitting one another
or the conveyor base.
Limit switch on the output conveyor:
There are 2 limit switches for the adjustment unit in the vi-
cinity of the output conveyors. They serve to secure the
transport area and to initialize the adjustment unit during
width adjustment.

Replacing the Solenoid Valve for the Adjustment Unit [00369014-xx] (applicable to
modular PCB conveyor only)
Parts
▪ Solenoid valve with cable for adjustment unit 1 [00363779-xx]
▪ Solenoid valve with cable for adjustment unit 2 [00363780-xx]
Overview
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.
► Unsolder the connection wires on the faulty limit
switch (1).
► Loosen and remove the two screws (2) fastening the
defective limit switch.
► Fit the new limit switch and re-solder the connection
wires in the correct allocation.
NOTICE! 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 tray and unplugged there.
This might be somewhat complicated depending on the
routing of cables inside the machine base.
You may wish to contact Siemens AG SMD Service re-
garding this work.
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 sides.
