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.

Replacing the Stepping Motor of the Width Adjustment System [00367174]
Overview
► 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.

CAUTION! Do not damage the toothed belt!
During the following removal and installation of the motor,
the toothed belt for the width adjustment drive must not
be stretched or kinked!
► Move the PCB conveyor to the position which gives
you best access to the stepping motor of the width
adjustment system.
► 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 eccentric axis (1) on the deflection pulley
and relieve the tension on the drive toothed belt (5).
CAUTION! Toothed belt must not come off!
When relaxing the toothed belt, make sure the belt does
not come off (skip) the toothed disks at the 3 adjustment
units. This would cause incorrect alignment of the adjust-
ment units. Secure these positions with a suitable tool
(screw clamp etc.)
► Remove the 4 fastening screws (3) and then lift out
the stepping motor (4).
► Unplug the connection cable in the cable duct.
► Fit the new stepping motor and reconnect the system
to the electrical system.
► Tension the drive toothed belt.
Position the measuring point of the belt tension de-
vice at the strand center (i.e. the longest distance be-
tween two toothed disks) of the conveyor toothed
belt.
► Set the tension of the drive toothed belt according to
the following values.
