Setting
► Use the software to move the conveyor sides into a position which allows you best access. As
an alternative, you can loosen the clamps for the relevant sides in dual conveyors.
7.2 "Loosening the Conveyor Side Clamps" [}207]
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
1.2 "Preparatory work..." [}16]
► Check the belt tension at the relevant measuring point.
► If the belt tension is not correct, set it with the help of the movable idler pulley.
► Repeat the measurement 4 times.
7.6.2.2 Calculating the belt tension
NOTICE
For conveyor belt only
This calculation only applies to the conveyor belt.
Fig.318: 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 pulleys parallel to the conveyor
belt.
 CAUTION!
Note that it is not always possible to
simply measure the distance
between the idler pulleys from cen-
ter to center.
.
► Calculate the belt tension using the fol-
lowing formula:
20000 [Hz mm]
/ idler pulley spacing [mm]
The permissible tolerance is always plus/
minus 10% of the calculated value.
Example
Distance between the idler pulleys: 235mm
Calculation:
20000 / 235 = 85 (rounded, exactly 85.106…)
10 % of 85.106… = 9 (rounded, exactly 8.5106…)
Result:
Belt tension: 85 +/-9 Hz

Removal and installation
► Replacement of the belt drive is identical to replacement of the conveyor drive. For more in-
formation about this read section 7.4.1 "Replacing the conveyor drive" [}218].
