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: 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
