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

5-26: Switch on sequence for pneumatic units
NOTE:
Prop. valve X58, controlled by relay K2, is immediately powered with machine ON. After
performing the reference run, the valve can be switched off via the software (default setting:
2 minutes).

5.3.4 Main Valve X59 for Machine Components
After the machine is switched on with the main switch, the valve is powered and air runs into the system.
Opening the covers has no effect on the supply of compressed air. The valve will only close if the voltage
supply fails or if the machine is switched off, in which case the docking unit at the changeover table and
the tape cutter 1-4, plus the PCB conveyor will no longer be supplied with compressed air. The valve is
controlled by relay K1, located in sector 4 (subdistributor). If the pressure falls below 4.5 bar, the CAN
bus will issue a signal.
The pressure for this 5/2 valve is manually adjusted by a regulator to 5 +0.1 bar.
