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.

1. Deflection pulley with slot
2. Measuring point of the belt tension measuring
device (strand center )
X The deflection pulley, around which the
conveyor toothed belt is run, is fastened at a
slot. The tension of the conveyor toothed belt
can be adjusted via this deflection pulley.
X Position the measuring point of the belt
tension device at the strand center (i.e. the
longest distance between the two deflection
pulleys) of the conveyor toothed belt.
X Set the tension of the drive toothed belt
according to the following values.
NOTE:
The tension frequencies per area may vary according to the different belt guides. The belt
tension always remains the same.

X Lift the lifting table unit (6) into the machine
and position it on the locating pins.
X Screw in the fastening screws (2) and (3).
X Reconnect to the electrical (4) and
compressed air (5) systems.
X Check the lifting table speed and the
functionality of the PCB clamping device,
without the lifting table plate.
X Adjust the speed of the lifting table.
X Carefully place the lifting table plate (1) onto
the lifting table unit and tighten the fastening
screws diagonally, so that the lifting table plate
does not stick.
