10.2 Adjustments on the modular conveyor
Please Note:
When any settings are made on the lifting table, the lifting table must be secured to prevent it mov-
ing. Press the emergency stop button.
10.2.1 Belt tension adjustment
Please Note:
The belt tension must be measured at the center of the belt (strand center), i.e. in the middle
where the distance between two idler pulleys is largest.
Fig. 10.2 - 1 Measuring and setting the conveyor belt tension
Every conveyor section contains an idler pulley that can be moved.
Loosen the fixing screw
(1) and move this idler pulley in order to set the belt tension for the asso-
ciated conveyor belt
(2).

Legend
The belt is tensioned by means of cams on the idler pulleys. The idler pulleys are located on the
left and right of the motor.

10.2.1.1 Settings for the belt tension
Please Note:
In the modular transport, 3 different lengths of toothed belts are used. The different belt tensions
between the conveyor tracks results from the different arrangement of the hexagon shafts and id-
ler pulleys.
Belt tension for the width adjustment: 30 Hz +/- -2 Hz
Belt tension for track 1 (single and dual conveyors)
Input conveyor: 102 Hz +/- 10 Hz
Placement area 1: 66 Hz +/- 7 Hz
Intermediate conveyor: 94 Hz +/- 9 Hz
Placement area 2: 66 Hz +/- 7 Hz
Output conveyor: 102 Hz +/- 10 Hz
Belt tension for track 2 (dual conveyor)
Input conveyor 144 Hz +/- 14 Hz
Placement area 1: 71 Hz +/- 7 Hz
Intermediate conveyor 94 Hz +/- 9 Hz
Placement area 2: 71 Hz +/- 7 Hz
Output conveyor 144 Hz +/- 14 Hz
