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].

Installation and adjustment
X Move the PCB conveyor to the position which
gives you best access to the lifting table.
X Move the Y gantries into the area outside the
PCB conveyor.
X Switch off the machine and secure it to prevent
unauthorized reactivation.
X Loosen the screws fastening the lifting table
plate and remove the lifting table plate from the
lifting table unit.
X Loosen the two screws (3) holding the
stabilizer (5).
X Undo the locknut (2) and take the stabilizer by
its handle (4), twisting it out of the mounting
block.
X 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.
X Use a torque wrench:
Secure this position with the locknut (2)
tightened to 8Nm.
X 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.
X If this is not the case, loosen the locknut and
turn the stabilizer approx. one rotation into the
mounting block.
X Fit the lifting table plate.
X Start SITEST and move the lifting table up.
X 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.
X Check the speed of the lifting table cylinder
and correct where necessary.
