When electrical power energizes the solenoid, the valve is actuated and compressed air flows from port 1 to port 3. This generates a vacuum at port 2 by means of the venturi principle. Suction cups can be connected to vacuum connection (2). Air entering vacuum connection (2) passes through an internal filter and is discharged to atmosphere, together with the supply air, via exhaust port 3. An integrated silencer reduces exhaust-air noise. When the solenoid valve is deenergized, vacuum generation ceases. 1 = Supply Port Types VADM-…-P/N includes a vacuum switch which allows the vacuum level 2 = Vacuum Connection to be monitored.

The pulse signal activates the suction solenoid of the vacuum generator, thus restoring the vacuum to another preset value. During the remaining cycle time, vacuum is maintained by the integral non-return valve eliminating the need to activate the suction solenoid. It is also possible to monitor a signal (A1) which is normally at +24V but which falls to 0V if the vacuum falls below the lower preset threshold by a further 65 mbar. This will, for example, occur if a workpiece falls off a suction cup, with the result that the desired vacuum level can no longer be generated. Connecting cables, sockets for solenoid coils, and vacuum switch are included. The switch must be operated only with the cable set supplied. Connections 1, 3 and 4 can be interchanged without causing damage to the switch. This unit is supplied complete with socket and cable assembly as shown below.
