3.6.2 Lifting table Conveyor
Service Manual SIPLACE SX1/SX2/DX1/DX2 FS02 149
► Unplug all electrical connections to the lifting table motors (three for each motor).
► Open the cable clamps for the electrical connections.
► Mark the direction of transport for the lifting table. This helps you avoid unintentionally fitting the lifting
table at the wrong angle later on (turned by 180 degrees).
► Loosen the six screws (EC: four screws) fastening the lifting table.
► Carefully lift the lifting table out of the machine.
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following instruc-
tions:
Manually Lowering the Lifting Table
If the lifting table stays in the top position, it can be manually lowered in the event of an emergency.
Procedure
CAUTION
Screws
Make sure that you do not loosen any other screws!
CAUTION
Heavy machine part!
When removing the lifting table, remember it is heavy. You may need to enlist the help of a sec-
ond person.
CAUTION
Installation instructions
► Make sure that the lifting table is aligned correctly in the direction of transport.
► Before you finally fix the lifting table into place, push it up to the stop in the direction of out-
put. This ensures that the lifting table is parallel.

NOTICE
Lifting table plate guides
► Mark the positions of the lifting table plate guides.
If these are still mistakenly exchanged, you will need to reset the parallelism of the lifting
table plates after installation.
► Remove the lifting table from the machine (see
"3.6.2.1 Replacing the Lifting Table Unit" [ ➙ 148]).
► Unplug the connection between the motor and the
rods (1).
► Loosen the screws (2) fastening the motor. Some of
these are only accessible if you move the rods up-
wards (thereby turning the gear shaft by 90 degrees).
CAUTION!
Make sure that you do not loosen the other four screws!
► Remove the motor.
CAUTION!
There are several shims on the gear shaft. These need to
be taken over to the new motor and fitted there in the
same positions and quantities.
CAUTION
Installation instructions
► Position the washers onto the motor axis in the exact places that they were removed from.
► Make sure that the motor connection cables do not rub against any parts. In particular,
make sure that they do not point upwards or downwards.

Parts, equipment and tools
▪ Conveyor drive [03051225-xx]
▪ Flat spiral spring [03075316-xx] (This is included in the spare parts kit.)
Removal
► Use the software to move the conveyor sides into the position which allows you best access. Alter-
natively, you can also loosen the conveyor side clamps on the dual conveyor (see "3.6.1 Loosening
the Conveyor Side Clamps" [ ➙ 143]).
► 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..." [ ➙ 13].
Installation
► Follow the removal instructions in reverse order for installation. Also observe the following instruc-
tions:
► Loosen the screws fixing the hexagonal shaft above
the conveyor drive and push this carefully into the
machine frame, as has already been done in the
diagram (5). This gives you more room for movement
(see also "3.6.5.3 Replacing the Hexagonal Shaft
[03057258-xx]" [ ➙ 167]).
CAUTION!
There are cables run inside the machine frame.
Make sure you do not damage these cables.
► Unplug the electrical connections to the conveyor
drive (3). Loosen the corresponding cable ties, if re-
quired.
► Fully unscrew the two top screws (2) fastening the
conveyor drive.
► Loosen the lower screw (4) fastening the conveyor
drive but do not full unscrew it.
► Lift the conveyor drive off the bottom screw. While do-
ing so, carefully unthread the conveyor drive from the
toothed belt (1) and remove the conveyor drive from
the machine.
CAUTION
Installation instructions
► Make sure that the toothed belt is positioned accurately in the guidance on the motor shaft
(see diagram below).
► While you tighten the screws fastening the conveyor drive, set the tension of the toothed
belt correctly (see "4.6.1.1 Setting the Tension of the Conveyor Drive Toothed Belt"
[ ➙ 274]).
