► Glue the sheet metal plate to the conveyor rail. Observe the following points:
– On the input side(1), the side metal sheet plate is attached 1mm towards the inside.
– On the output side(2), the side metal sheet plate protrudes the rail by 2mm.
► Fit the toothed belt.

Removal
CAUTION
Toothed belt
► Make sure that the toothed belt is not folded or otherwise damaged.
► 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.
Fig.45: Movable idler pulleys
► If you are replacing a movable idler pulley(1),
you will have to move the conveyor rail to get
access to the T-slot nut (see below).
CAUTION!
Fix the T slot nut!
When replacing a movable idler pulley, fix the T
slot nut to the inner side of the conveyor rail (see
description below).
.
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.

CAUTION
Replacing the movable idler pulley - fixing the T-slot nut
The movable idler pulleys are fixed to the inner side of the conveyor rail with a T slot nut
[03113747-xx].
If you want to remove a movable idler pulley, proceed as follows:
ü Before removing a movable idler pulley, first fix the T-slot nut.
► (1) When removing a movable idler pulley in the middle of the conveyor rail, you can
reach the T-slot nut through the hole on the other side of the conveyor rail. Use your
finger or an appropriate tool to fix the T slot nut.
► (2) When removing a movable idler pulley at the beginning or the end of the conveyor
rail, fix the T slot nut with your finger (the conveyor rails are open at the side).
ð The T slot nut must not fall into the conveyor rail! The lack of room makes sub-
sequent insertion and fixture highly complicated if not impossible!
► Loosen the movable idler pulley.
CAUTION
Loosen the movable idler pulley only as far as necessary!
► Do not remove the movable idler pulley (unless you explicitly need to remove it). Oth-
erwise the T slot nut on the inner side will fall into the conveyor rail.
► Remove the idler pulley to be replaced.
CAUTION
Spacer
The fastening screw for some idler pulleys also holds the spacers in place.
► Make sure that you do not loose these.
► Unthread the deflection pulley from the conveyor toothed belt and remove it.
