8.7.1 Vacuum System Function
The pneumatic distributor (1) supplies the pressure control valve (2), the holding circuit (3) and the
return cylinder with 4.5 bar compressed air.
The compressed air is fed directly through the holding circuit (3) to the valve terminal (6). There it is
distributed into 12 channels.
Each channel in the holding circuit can be separately opened or closed with a valve (7).
The compressed air is fed from the valve terminal to the holding circuit, through the 12 channels. The
vacuum for the holding circuit of all 12 segments is generated there via 12 venturi nozzles.
The vacuum is fed from the holding circuit via the star carrier (5) to the nozzle segment (4).
The holding circuit sensor is located in the CPP head cover (8). The holding circuit sensor can be
used to measure the vacuum of any segment which is in the 12.00 position.
