Installation
► Follow the removal instructions in reverse order for installation. Also observe the following
instructions:
CAUTION
Installation instructions
► Tighten the fixing screw with a torque of 0.58Nm. Make sure that you do not tighten
the screws too much. This could cause irreparable damage to the conveyor!
The corresponding threads are only in 1.5 to 2mm thick plates and could be damaged
if you use a torque which is too high.
For this reason, avoid using screws which are too short. Use a measuring scale to
check, if needed!
► Use any spacers available.
► Do not bend or damage the toothed belt.
► Make sure that the toothed belt is positioned accurately in the guidance on the motor
shaft or in the belt drive.
► Remove the adhesive tape, if necessary.
► While you tighten the idler pulley, set the tension of the toothed belt correctly (see Set-
ting the tension of the conveyor 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.
– Make sure that the rear side of the conveyor rail is also accessible.
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
Fig.48: Movable idler pulleys
► Loosen the fixing screw of the relevant movable
idler pulley(1) to release the tension of the belt.
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). Otherwise the T
slot nut on the inner side fall into the conveyor
rail.
