ATTENTION: Do not damage the
toothed belt!
The toothed belts must not be
stretched or kinked!
X Insert the new toothed belt (1) into the motor
mount (2) and place the belt around the
toothed disk (3) of the geared motor.
X Place the toothed belt around the toothed disk
(4) of the conveyor toothed belt and insert the
toothed disk in its mount.
X Use a rubber mallet to carefully knock the
toothed disk into position.
X Install the shim/washer (7) and the circlip (8).
X Loosely fasten the DC geared motor (5) with
the 4 M3 hexagonal socket-head screws (6).
The entire width of the toothed belt must
engage at the top and bottom toothed disks.
X Tension the toothed belt (1) by moving the DC
geared motor in the fastening holes. The belt
tension must be between
10 and 15 N.
X Fit the complete motor unit.
NOTE:
After the drive unit has been installed,
you must make certain that the
direction of rotation and the conveyor
speed (motor voltage) are correct.

Overview
Removal
X Move the PCB conveyor to the position which gives you best access to the conveyor belt
X Move the Y gantries into the area outside the PCB conveyor.
X Switch off the machine and secure it to prevent unauthorized reactivation.
NOTE:
The following diagrams apply to the
standard conveyor system (fixed side -
right). Depending on the conveyor side
(left or right), either the hexagon shaft
guided block or the DC geared motor
will be fitted.

2. Deflection pulley with slot
3. Conveyor toothed belt
The way in which the conveyor toothed belt is run
around the deflection pulley depends upon the
transport area concerned. Please observe this belt
guidance during assembly and disassembly.
Please also bear in mind the following differences
during assembly and disassembly:
The drive unit is installed at an angle (tilted),
according to the requirements of the
installation site.
Respective to conveyor edge, either the tape
drive (mount) or the drive unit with DC geared
motor is mounted.

Installation
X Tighten the fastening screws.
X Adjust the belt tension.
X Loosen the deflection pulley (2) with the slot
and relieve the tension on the conveyor
toothed belt (3).
ATTENTION: The deflection pulleys
have been assembled with sliding
nuts.
The screw for the deflection pulley
should only be loosened! If the screw is
removed, the sliding nut will fall behind
the conveyor cheek side cover. You
then need to dismantle the cover to
retrieve the nut.
X If the drive unit is installed, remove it.
X If the tape drive (hexagon shaft guided block)
(1) is installed, remove the 3 fastening screws.
X Carefully pull off the tape drive (hexagon shaft
guided block) (1) or drive unit, while also gently
unthreading the conveyor toothed belt (3)
through the opening in the conveyor side.

ATTENTION: Do not damage the
toothed belt!
The toothed belts must not be
stretched or kinked!
X Feed the new conveyor toothed belt (2) into
the drive unit and weave it round the deflection
pulleys (3).
X Insert the tape drive (mount) or drive unit (1)
with the conveyor toothed belt (2) and fasten.

NOTE:
When replacing the belt on the passive side (tape drive without drive unit), set the track width to
50 mm. The tape drive must be aligned towards the active side, allowing smooth axial
movement of the hexagonal shafts.
