Model GVMAXHD__L: vacuum pump with pulse-triggered bistable vacuum control and NC blow-off (patented system)
In the event of power failure, the vacuum pump maintains its previous state.
More specifically, one of the following two scenarios will take place should the failure occur:
- During vacuum generation, the vacuum is maintained => fail-safe
- During blow-off or when the pump is off, the pump remains “Off”
Vacuum control is automatically stopped when the blow-off command is activated.
The vacuum can only be stopped with the blow-off command.
In the event of compressed air failure, the vacuum is no longer maintained.
• Pulse-triggered bistable vacuum control solenoid valve (50 ms
min.)
• 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.
