4.4.5.1 Adjusting the Tension of the Conveyor Toothed Belt
Adjusting the Tension of the Conveyor Toothed Belt
CAUTION! Do not damage the toothed belt!
The toothed belts must not be stretched or kinked!
► Feed the new conveyor toothed belt (2) into the drive
unit and weave it round the deflection pulleys (3).
► Insert the tape drive (mount) or drive unit (1) with the
conveyor toothed belt (2) and fasten.

NOTICE
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 move-
ment of the hexagonal shafts.
Legend
1. Deflection pulley with slot
2. Measuring point of the belt tension measuring device
(strand center )
► 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.
► Position the measuring point of the belt tension de-
vice at the strand center (i.e. the longest distance be-
tween the two deflection pulleys) of the conveyor
toothed belt.
► Set the tension of the drive toothed belt according to
the following values.
NOTICE
The tension frequencies per area may vary according to the different belt guides. The belt ten-
sion always remains the same.

► Move the PCB conveyor to a suitable position from
which you have best access to the lifting table unit.
► Loosen the screw fastening the lifting table plate (1)
and remove the lifting table plate from the lifting table
unit.
► Loosen the screws (2) and (3) fastening the lifting ta-
ble unit.
► Remove the cover on the conveyor conversion board
and unplug the connection cable (4) from the lifting
table unit.
► Unplug the compressed air connection (5).
► Carefully lift the lifting table (6) off the locating pins.
CAUTION! Heavy machine part!
When removing the lifting table, remember it is heavy
