5.3.8 Compressed Air Supply to the Conveyor
As with the tape cutters, the compressed air supply to the conveyors is switched via the safety valve.
This means that the safety valve is only switched via the control ON function once all safety circuits have
closed and made contact.
In the conveyor, the lifting table and the width adjustment driver are supplied with compressed air.
5.3.9 Compressed Air Supply to the Docking Unit (Changeover Table)
5.3.10 Bulk Case System and Nozzle Changer
Another adjustable regulator is used to reduce the 5.0 bar to 2.5 +0.5 bar. This air supply is used for the
bulk case and for the nozzle changer at the C&P 6/12 head.

5.3.11 Compressed Air Supply to the C&P20A
The 4.8 bar air supply to the C&P20A is needed for the following functions:
Vacuum supply in the holding circuit
Vacuum and air blast supply for the placement circuit (pressure control valve)
Cooling facility for the X axis motor.

Another use of the 4.8 bar compressed air is for
the Z axis safety mode. As long as the machine is
in normal mode, the Z axis can move freely within
its travel range. In the case of power cuts or when
the machine is switched off, a safety mode is
needed since the weight of the Z axis causes it to
fall down and it could be damaged when the gantry
is moved. With the help of the return unit, the Z
axis can be moved to a safe position in just a few
ms. In the event of a fault, like a power cut, the
power fail mode is also activated, which powers
the Z axis for about 200 ms seconds with the aid
of a capacitor, located in the main power supply.
This ensures that the Z axis moves up with the
power provided and with additional help from the
return spring.
