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In the event of compressed air failure, the vacuum is no longer maintained.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
- L: 24 V DC vacuum control with min. pulse-triggering of 50 ms

(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
Powerful blow-off (version GVMAXHD…F2)
This type of blow-off allows for objects to be quickly released in the event that the pump cannot be placed as close as possible to the suction cups, or to reduce the cycle time as much as possible.
The isolation valve F directs the entire blow-off flow towards the suction cups. In this case, the blow-off pressure is identical to the vacuum pump’s compressed air supply pressure.
