Adjustment
► Use the software or manually move the conveyor rail into a position which allows you best
access.
– To move the conveyor rail manually, pull the toothed belt of the width adjustment unit.
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
► Check the belt tension at the relevant measuring point.
► If the belt tension is not correct, adjust the movable idler pulley.
CAUTION
Do not let the T groove nut fall into the conveyor rail!
► Do not remove the movable idler pulley completely, to make sure that the grooved nut
does not fall into the conveyor rail.
► Repeat the measurement four times.
4.5.2.2 Calculating the belt tension
NOTICE
For conveyor belt only
This calculation only applies to the conveyor belts of SIPLACE TX machines.
Fig.40: 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 pulleys
from center to center.
.
► Calculate the belt tension using the following for-
mula:
(15000 / 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 15000 / 235 = 64 (rounded, exactly 63.829…)
10 % von 63.829… = 6 (rounded, exactly 6.3829…)
Result → Belt tension: 64 +/- 6 Hz

Removal
CAUTION
Do not loosen the wrong screws
Make sure that you do not loosen any other screws except those ones explicitly mentioned.
Loosening other screws could lead to irreparable misalignment or damage to the conveyor.
► Use the software or manually move the conveyor rail into a position which allows you best
access.
– To move the conveyor rail manually, pull the toothed belt of the width adjustment unit.
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
► Remove the relevant toothed belt.
Replacing the toothed belt (conveyor belt)
► Pull the old side sheet metal plate off the conveyor rail.

Installation
► Clean the adhesive surfaces on the conveyor rail.
Fig.42: Attaching the adhesive tapes
► Attach the adhesive tapes to the side sheet metal plates as described in the figure. Observe
the following points:
– In the input area(1) towards the outside of the machine, electrically conductive adhesive
tape 3M-9469 [03154790-xx] is applied on a 91mm wide stripe.
– In the placement area(2), the electrically conductive adhesive tape is not used.
– In the output area(3) towards the outside of the machine, a 54mm wide stripe is applied
with electrically conductive adhesive tape 3M-9469 [03154790-xx].
– The other surfaces of the sheet metal plates are not applied with electrically conductive
tape 3M-9713 [03154789‑xx]. Make sure to keep the holes for the light barriers free.
