3.6.8 Replacing the Lifting Table Unit
Replacing the Lifting Table Unit
Parts
▪ Lifting table unit for single conveyor [03029170-xx],
backwards compatible to [00358653-xx]
▪ Lifting table unit for dual conveyor [03029171-xx],
backwards compatible to [00358654-xx]
▪ Lifting table unit for dual conveyor of X4I and quad lane [03059051-xx]
▪ Lifting table unit for single conveyor of X4I [03065192-xx]
► Loosen the screws fastening the lifting table plate (1) diagonally and evenly and then remove the
lifting table plate from the lifting table unit.
NOTICE
Single, dual and quad lane conveyor
The replacement is shown here using the example of the lifting table unit for the dual or quad
lane conveyor (QC). Replacement of the lifting table unit for the single conveyor is the same.
New lifting table bumper for SIPLACE X4I
The bumpers (2) under the lifting table plate (1) are now
35 mm long.
CAUTION!
Loosen the lifting table plate screws diagonally and even-
ly!
The screws fixing the lifting table plate of the SIPLACE
X4I and any future lifting tables with a bumper length of
35 mm must be loosened evenly, otherwise the lifting ta-
ble plate will be subjected to excessive tension.
1. Lifting table plates (dual conveyor shown here)
2. Six fastening screws for lifting table (M8x100)
3. Two fastening screws for lifting table (M6x50)
► Move the PCB conveyor to a suitable position from
which you have best access to the lifting table unit.
NOTICE!
Quad lane conveyor
When using a quad lane conveyor, it is advisable to move
the first conveyor edge to one side and the second to fifth
edges as far as possible to the other side.

3.6.8 Replacing the Lifting Table Unit Modular PCB Conveyor System
Service Manual SIPLACE X Series 167
► Loosen the screws (2) and (3), fastening the lifting table unit.
► Remove the cover on the conveyor conversion board and unplug the connection cable (4) from the
lifting table unit.
► Unplug the compressed air connection (5).
► Carefully lift the lifting table (6) off the locating pins.
Installation
► Check the lifting table speed and the functionality of the PCB clamping device, without the lifting table
plate.
► If necessary, readjust the values. ("5.4.8 Lifting Table Functions" [ ➙ 339])
► Carefully place the lifting table plate (1) onto the lifting table unit and tighten the fastening screws
diagonally, so that the lifting table plate does not stick.
► Check the lifting table speed once the lifting table plate has been installed.
CAUTION
Screw positions!
Do not loosen the screws directly next to item (2)! If you do, the lifting table mechanics will be
displaced which could lead to tension and increased wear.
CAUTION
Heavy machine part!
When removing the lifting table, remember it is heavy (17.5 kg).
CAUTION!
Deaerate the lifting table valve!
When using a SIPLACE X4I or any PCB conveyors with
a bumper length of 35 mm, the lifting table valve inlet 2
must be de-aerated before reassembly. This ensures
free movement of the mechanism.
The lifting table mechanism can be raised during assem-
bly, to prevent distortion of the lifting table plate.
► Lift the lifting table unit (6) into the machine and posi-
tion it on the locating pins.
► Screw in the fastening screws (2) and (3).
► Reconnect to the electrical (4) and compressed air
(5) systems.
NOTICE!
Run the tables under the mechanics so that these are not
damaged when you move the lifting table upwards.

3.6.9 Replacing the Lifting Table Stabilizer (Stabilizer Unit) [00358684-xx]
Replacing the Lifting Table Stabilizer (Stabilizer Unit) [00358684-xx]
Overview
Tools and equipment required
▪ Torque wrench with plug-in ratchet [00386175-xx]
▪ Plug-in wrench 16 mm [00386177-xx]
Removal
1. Actuator
2. Locknut
3. Fastening screws
4. Handle
5. Stabilizer [00358684-xx]
The stabilizer enables the lifting table to be moved gently
upwards. It prevents the PCBs from being clamped in
with too much impact.
The stabilizer consists of the shock absorber [00367737-
xx] and the damping block [00367782-xx].
► Move the PCB conveyor to the position which gives
you best access to the lifting table.
► Move the Y gantries into the area outside the PCB
conveyor.
► Switch off the machine and secure it to prevent unau-
thorized reactivation.
► Loosen the screws fastening the lifting table plate and
remove the lifting table plate from the lifting table unit.
► Loosen the two screws (3) holding the stabilizer (5).
► Undo the locknut (2) and take the stabilizer by its han-
dle (4), twisting it out of the mounting block.
