Removal

► Use the software or manually move the conveyor rail into a position which allows you best ac-

cess.

– 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. Observe the instructions in section 1.2 "Preparatory Work..." [}15].

► Move all gantries out of the transport area as far as possible at one side of the machine.

► The fastening screws of the conveyor drives are on the outer side of the conveyor. You may

have to move out the COTi to get access to these screws. In this case follow the instructions

to move out the COTi.

CAUTION

Installation instructions

► Make sure that the toothed belt is not folded or otherwise damaged.

► Make sure that the toothed belt is accurately positioned in the guidance on the motor

shaft.

► Carefully thread in the toothed belt. To do this, carefully lift the toothed belt a little (e.g.

with the shorter end of an Allen key).

► Tighten the three screws fastening the conveyor drive hand-tight. Set the tension of

the toothed belt correctly in same time at 210+-20Hz.

► Replace any cables ties where needed.

Replace, in particular, the cable tie on the motor. Make sure that the cables, cable ties

and, in particular, the cable tie heads are not damaged on edges or rubbed against

anything when you adjust the conveyor sides.

Also pay attention to the cable ties on the trailing cable and to the shield connection

on the conveyor drive.

Perform these checks along the whole width of the conveyor.
