4.5.2.3 Installation Check
Installation Check
The following steps apply for the rotary axis of the P&P
head, version 14 (without metal elbow for vacuum feed-in
on the DP turning unit):
CAUTION! Check the alignment of the rotary ax-
is!
Check that the rotary axis is always aligned towards the
front.
► This means that the rotary axis must not hit any parts
when in the top Z axis position (2). Check this several
times by moving the Z axis to its minimum and maxi-
mum positions and turning the rotary axis, with the
vacuum hose connected. This should then automati-
cally revert to its original, free-moving position (1).
► Run the SITEST program to calibrate the vacuum
system (calibrate „Vacuum closed“ and „zero correc-
tion for the Pressure regulator“).

The digital vacuum generator has a thin high-precision
tube (additional volume tube) in the vacuum supply to the
nozzle. Between this pipe and the vacuum connection of
the vacuum generator, there is an air filter attached to the
TWIN segment.
► Open the threaded pin on the stopper ((2) already re-
moved in the diagram here) of the return unit and un-
screw the stopper.
► Pull the silicon hose (4) off the connecting piece of
the high-precision tube (5).
► Loosen the two clamping screws (6) on the air filter.
► Loosen the two fastening screws (1) on the vacuum
control system (3) and remove the vacuum control
system.
► Pull the vacuum control system downwards so that it
can be unplugged from the head main board (7).
► Unthread the vacuum control system next to the re-
turn cylinder (8) and above the DP turning unit (9) on
the Z mechanics.
