► Loosen the top two idler pulleys(1).
► Loosen the screws fastening the belt drive (3)
and the conveyor drive.
► If you replace a conveyor belt in the placement
area, you will also need to loosen the top retain-
ing screw (2) on the spring. Make sure that you
do not lose the spring and the bushing on the
screw. When you refit them, check the bushing
for correct orientation.
► Carefully unthread the conveyor belt.
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following in-
structions:
CAUTION
Installation instructions
► Check the new toothed belt before fitting it. Hold it up high. It should hang loose and
should not twist.
► Make sure that the toothed belt is not folded or damaged otherwise.
► Make sure that the toothed belt is positioned accurately in the guidance on the motor
shaft or in the belt drive.
► If you have loosened the spring, check the bushing for correct orientation when you fit
it back again (see also Replacing the Tension Spring on the Clamping Plate
[03088949-xx]).
► While tightening the movable idler pulley, set the tension of the toothed belt correctly
(see 4.1.6.1 "Setting the Tension of the Conveyor Toothed Belt" [}69]).
4.1.6 Belt Tension
The precalculated values for setting the belt tension can be found in the following chapters.
In addition, the value for any section of the conveyor belt can be calculated using a formula. (See
4.1.6.2 "Calculating the Belt Tension" [}71])

2. Placement area: 175 +/- 18 Hz
3. Output area: 100 +/- 10 Hz
Setting
► Use the software to move the conveyor rails into a position which allows you best access. Al-
ternatively, you can also loosen the conveyor rail clamps on the dual conveyor.
► Switch off the machine, disconnect it from the power supply and secure it to prevent unauthor-
ized reactivation. Observe the instructions in section 1.2 "Preparatory Work..." [}46].
► Check the tension at the relevant measuring point.
► If the tension is not correct, loosen the screw fastening the movable idler pulley and correct
the tension.

► Repeat the measurement 4 times.
4.1.6.2 Calculating the Belt Tension
NOTICE
For conveyor belt only
This calculation only applies to the conveyor belt.
Fig.21: Measuring the distance
► Define the two idler pulleys between which you
want to set the belt tension. If possible, do not
use the movable idler pulleys.
► Measure the distance between the two idler pul-
leys parallel to the conveyor belt. (see dia-
gram)
CAUTION!
Note that it is not always possible to simply
measure the distance between the idler pul-
leys from center to center.
.
► Calculate the belt tension using the following for-
mula:
(20000 / idler pulley spacing [mm]) [Hz]
The permissible tolerance is always plus/minus 10%
of the calculated value.
Example
Distance between the idler pulleys: 235mm
Calculation:
20000 / 235 = 85 (rounded, exactly 85.106…)
10 % of 85.106… = 9 (rounded, exactly 8.5106…)
Result:
Belt tension: 85 +/-9 Hz
