5.3.5 Proportional Valve, Proportional Regulator X58
When switching the machine on at the main switch, air is supplied to all placement heads.
After the reference run is performed, the air can be switched off by the software after a certain time (as
standard 2 min.) and air will stop flowing through the vacuum system of the placement heads.
The X58 proportionate valve regulates the compressed air to 4.8 +0.1 bar for the placement head.
Included within this regulator block is a pressure sensor which monitors the outgoing air pressure. If the
pressure falls below 4.5 bar, the CAN bus will issue a signal. The valve is controlled by relay K2, located
in section 2, main distributor.

5.3.6 Safety Valve X60
Safety valve for controlling the compressed air for transport and tape cutter. The compressed air supply
for these modules is only present after the start button has been pressed and all safety requirements
have been fulfilled (safety loop closed).

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.

5.3.10 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.
