5.3.3 Pneumatic Unit
5.3.3.1 Overview of Pneumatic Unit
The pneumatic unit is a fixed installation inside the machine. The unit is accessible via a door and
contains the complete compressed air supply for all consumer devices.

NOTE: Different pressure
Note the different pressure for the nozzle changer of the D4 machine, which is considerably
higher (5.1 +/- 0.1 bar) than that for the nozzle changers of D1/D2 machines.

5.3.3.2 Compressed Air Distributor Block
The pneumatic unit is used to prepare and distribute the compressed air required in the machine.. The
pressure at the compressed air connection must be at least 5.5 bar.
The following pneumatic circuits are supplied with compressed air via the distributor block:

5.3.3.3 Switch ON Sequence for Pneumatic Units
5-13: Switch ON sequence for pneumatic units (example: D4)
The time for deactivation of the proportionate valve can be changed in the station software.
Settings
configure compressed air deactivation
switch off after 1-60 minutes
5.3.3.4 Main Valve X89 for Regulation of Compressed Air
After switching on the machine via the main switch, the valve is opened and compressed air flows into
the system. Opening covers, for example, has no effect on the air supply. However, if the 24 V voltage
supply fails or if the machine is switched off, the valve will close and the machine components will no
longer be supplied with compressed air. The valve is regulated via a pressure sensor. If the pressure
falls below 5.0 bar, the CAN bus will issue a signal.
NOTE:
The proportional valve X89 is enabled as soon as the machine is switched on. After performing
the reference run, the proportionate valve X89 can be switched off via the software (2 minutes
as a default).
NOTE:
This main pressure regulator can be damaged if the machine is turned on without compressed
air supplied. Therefore if the compressed air supply fails, turn of the machine.
