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In the event of compressed air failure, the vacuum is no longer maintained.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
• 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.
