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]

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.

Removal/installation
► 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 unauthorized reactivation.
► Insert and twist the new stabilizer (5) until the plunger
just touches the actuator (1), so that the lifting table
can be gently moved upwards.
► Using the torque wrench:
Secure this position with the locknut (2) tightened to
8Nm.
► Check whether the stabilizer has been fixed onto the
mounting block with the locknut and that the stabilizer
plunger has a gap of approx. 0.1 mm to the actuator
(gap in untriggered mode). In this default setting, the
lifting table should move up gently.
► If this is not the case, loosen the locknut and turn the
stabilizer approx. one rotation into the mounting
block.
► Fit the lifting table plate.
► Start SITEST and move the lifting table up.
► The lifting table should move up gently i.e. you should
not hear the PCB clamping device audibly locking
into place and no clamping device error messages
should be issued.
► Check the speed of the lifting table cylinder and cor-
rect where necessary.

Service Manual SIPLACE D1/D1i/D2/D2i 99
► Loosen the screws fastening the lifting table plate and remove the lifting table plate from the lifting
table unit.
► Switch off the compressed air supply and release the air at the pneumatic unit filter.
► Loosen the screws fastening the connection plug and then unplug it.
► Detach the compressed air connections and remove the old solenoid valve.
► Fit the new solenoid valve and reconnect the electrical and compressed air systems.
► Check the speed of the lifting table cylinder and correct where necessary (see "6.7.11.2 Adjusting
the Lifting Table Speed" [ ➙ 273]).

► 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.
► Switch off the compressed air supply.
► Loosen the screws fastening the lifting table plate and
remove the lifting table plate from the lifting table unit.
► Loosen the fastening screws for the solenoid valve
(4) and remove it from the lifting table cylinder. You
may need to unplug the cables and hoses from the
solenoid valve and loosen the relevant cable ties.
► Loosen the grub screw at the end position proximity
switch (1) and push the end position proximity switch
out of the lifting table cylinder guide rail (2). Open the
corresponding cable ties to help you.
► Loosen the locknut on the piston rod (3) and twist the
piston rod out until it releases itself from the actuator.
► Loosen and remove the two screws fastening the lift-
ing table cylinder (2).
