3.5.3 Replace the Load Axis Drive Toothed Belt
➢ When installing the motor, make sure that it is aligned parallel to the slide bar.
➢ Readjust the belt tension (see "3.5.6 Setting the Load Axis Belt Tension" [➙ 3-44]).
Spare Part
• Toothed belt 10T5/1640 E [03053795-xx]
Preparations
➢ Move the tower into the refill position.
➢ Remove all waffle pack tray carriers (WPTCs) from the tower.
➢ Move the tower downwards.
⇨ Check sensors and functions ⇨ Check sensors and functions of specific components ⇨
⇨ Location ⇨ Check functions for WPC ⇨ Move into transport position.
➢ Undock the WPC from the SIPLACE machine and move it to a suitable position for service
work.
➢ Switch the WPC off at the main switch.
➢ Unplug from the power supply and secure the WPC to prevent unauthorized reactivation.
➢ Remove the cover from the non-stop module (see "3.5.1.1 Remove the Cover on the Load
Unit" [➙ 3-33]).
➢ Remove the hand guard from the feed axis (see "3.5.1.2 Removing the Right Side Cover
from the WPC" [➙ 3-33]).

Removal / Installation
➢ Relax the belt by loosening the two fastening screws (1) sealed with locking varnish, at the
tensioning device with the deflection pulley (2).
➢ Loosen the four screws fastening the driver unit (3). The clamping unit for the toothed belt is
located underneath this.
➢ Carefully remove the driver unit. This toothed belt is now loose.
➢ Note how the toothed belt is run, so that you can fit it again correctly later on. Pull the
toothed belt over the two deflection pulleys (back and front) and out of the WPC.
➢ Remove the tensioning device and deflection pulley (2), so that you can feed in the new
toothed belt more easily. To do this, loosen the two fastening screws (1).
➢ Insert and run the toothed belt from the tensioning device (1) to the deflection pulley (4). The
toothed belt should exit below the bottom deflection pulley (4).
➢ Place the one end of the toothed belt around the deflection pulley (4) and insert into the
clamping unit (5).
➢ Place the other end around the deflection pulley of the tensioning unit (1) and then insert
into the clamping unit (5) from the other side.

➢ Fit the tensioning device with deflection pulley and fix into place with the two fastening
screws.
➢ Readjust the belt tension (see "3.5.6 Setting the Load Axis Belt Tension" [➙ 3-44]).
➢ Continue with chapter "4.3 Calibrating the Load Axis (WPC6 only)" [➙ 4-135].

3.5.4 Replace the Lifting Magnets
Spare Parts
• Lifting magnet for opening safety flap 03057345-xx
• Lifting magnet for closing the safety flap 03057344-xx
• 2 x DIN 471-4x0.4-C67 00095480-xx (retaining ring)
• Cable: lifting magnet for closing the safety flap [03058203-xx]
Preparation
➢
Remove the cover of the NSM module (see "3.5.1.1 Remove the Cover on the Load Unit"
[➙ 3-33]).
➢ The two ends of the toothed belt must be inserted
into the clamping unit (2) so that the clamping unit
teeth engage with the belt teeth. The two ends must
meet (1).
➢ Note the length of the new toothed belt. The toothed
belt is 1640 mm long/ number of teeth: 328.
➢ If the belt is too long, shorten it to the correct length.
➢ Fit the driver unit onto the clamping unit (2). Tighten
the 4 fastening screws "crosswise" with a torque of
1.3 Nm.
