Pneumatic diagram
Model GVMAXHD__V: vacuum pump with NO vacuum control and NC blow-off.
In the event of power failure, vacuum is still generated: object is held in place => fail-safe.
In the event of compressed air failure, the vacuum is no longer maintained.
• NO vacuum control solenoid valve
• NC blow-off control solenoid valve
• Blow-off controlled by external signal
Electrical connections
(1) 24 V DC suction command, depending on version:
- S: 24 V DC vacuum control
- V: 24 V DC vacuum off command

(2) DO2 configurable: - ASC status (default)
- or Pressure fault (below 5 bar or above 8 bar)
- or Power supply fault (below 21.6 V or above 26.4 V)
- or ASC fault
- or Object lost L: 24 V DC vacuum control with min. pulse-triggering of 50 ms
Blow-off
• Standard blow-off (version GVMAXHD…F1)
The blow-off flow is directed into the vacuum network and ensures the
object is released in most applications.
