The further development of the vacuum switch
In addition to the described functions,
1 External controller F activates the pressure sensor
Pressure sensor A checks the vacuum status
No vacuum present
2 Pressure sensor activates the VG solenoid B
Valve for compressed air supply is opened
Vacuum generation E is activated
3 Vacuum level 150 mbar below the maximum level is exceeded
Pressure sensor sends an enable signal to external controller (PLC) F
Transport process can start
4 The specified maximum level is achieved
Pressure sensor A switches the VG solenoid off
Compressed air supply stopped
Vacuum generation E interrupted
Non-return valve D prevents the vacuum level from being purged
5 Leakage causes the vacuum level to drop to the minimum value
Pressure sensor A switches the VG solenoid on again
Vacuum generation E is active again
Fault: Transport stopped
6 Major leakage causes an overly large drop in the vacuum level
Vacuum generator E cannot compensate for the drop in level
7 Vacuum level is 150 mbar below the minimum value
External controller interrupts the transport process
Vacuum generation E is ended
Cycle ended: Vacuum off
8 Transport process ended
External controller (PLC) F deactivates VG solenoid
Vacuum generation E is ended
External controller F switches on ejector RP solenoid C WH
Ejector pulse activated
