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.

6.7.1 Setting the Tension of the Conveyor Toothed Belt and the Width Adjustment Unit [ ➙ 261]
► Loosen the screws fastening the lifting table plate and
remove the lifting table plate from the lifting table unit.
► Loosen the eccentric axle (1) on the deflection pulley
and relieve the tension on the drive toothed belt (5).
CAUTION!
Parallelism of conveyor side: 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 2 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.
► Adjust the tension of the drive toothed belt.

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.
