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

NOTICE
Different pressure
Observe the different pressure for the nozzle changer on the D4/D4i machine (5.1 +/- 0.1 bar),
which is significantly higher than that for the nozzle changer of the D1/D2/D1i/D2i machines.

5.3.3.2 Compressed Air Distributor Block
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:

The time for deactivation of the proportionate valve can be changed in the station software.
▪ Settings
▪ Configure compressed air
▪ switch off after 1-60 minutes

5.3.3.4 Main Valve X89 for Regulation of Compressed Air
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.
NOTICE
Cause of Hazard
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).
NOTICE
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.
