5.3.1 Pneumatic Unit
The pneumatic unit is mounted on a compact slide-in module, and located on the right side of the middle
section. A lockable door prevents access to the unit, which contains the whole compressed air supply
as required for the machine and its options. The pneumatic unit also contains the conveyor control, which
assumes control of PCB transportation in the machine and to the upstream and downstream stations.

The input pressure (5-10 bar) flows through the compressed air filter. These need to be checked and
serviced at regular intervals. (see maintenance guide)
The compressed air is divided between two main paths via the compressed air distributor.
▪ Path 1: Compressed air supply to placement heads
▪ Path 2: Compressed air supply to machine components
▪ Path 1: All 4 gantries (placement heads are supplied with constant compressed air of 4.8 bar via the
proportionate valve.
▪ Path 2: The pressure for the machine components is set with a manual regulator to 5.0 +/-0.5 bar,
after the compressed air distributor. Afterwards, this path divides into three other paths.
– Path 2.1 This path supplies the docking units and the nozzle changer of the C&P20A head
directly with the 5.0 bar set at the manual regulator, via an electronic valve.
– Path 2.2 This path branches off after the electronic valve and the pressure is reduced via a
manual regulator to 2.5 +/-0.5 bar, for the bulkcase feeder option and the nozzle changers of the
C&P6/12 heads. (not X4I)
– Path 2.3 is switched via a safety valve and supplies 5.0 bar, set with a manual regulator, for the
conveyor and the cutters.
The input pressure and all pressures which can be set can also be controlled via manometers.

5.3.2 Overview Pneumatic System
The compressed air with 5-10 bar passes through the filter and is split into 2 main paths. 1st path is into
the main regulator and 2nd. path is into the proportional valve.
path 1: proportional valve X58 for regulating 5.0 +0.1 bar output (automatically adjusted)
▪ C&P (input vacuum generator head 4.6 +0.1)
▪ Twin head segment 1 (input vacuum generator head 4.6 +0.1))
▪ Twin head segment 2 (input vacuum generator head 4.6 +0.1))
path 2: Main valve X59 for regulating 5 +0.1 bar (manually adjusted)
▪ Docking unit for changeover table
▪ Conveyor (width adjustment and lifting table)
▪ Regulator for manually adjusting the air pressure used for bulkcase and nozzle changer, reduced to
2.5 +-0.5 bar
▪ Safety valve X60 for tape cutter and conveyor
