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" [}162]
► 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.
► Correct the belt tension when needed, using 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.266: 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: 235mm
Calculation:
20000 / 235 = 85 (rounded, exactly 85.106…)
10 % of 85.106… = 9 (rounded, exactly 8.5106…)
Result:
Belt tension: 85 +/-9 Hz
