The ejector has an integrated air saving function and automatically regulates the vacuum in suction
mode:
•
The electronics switch the venturi nozzle off as soon as the vacuum limit value set for switching
point SP1 is reached.
•
When objects with airtight surfaces are picked up, the integrated non-return valve prevents the vac-
uum from dropping.
•
If leakages cause the system vacuum to drop below the limit value configured for the switching
point rP1, the venturi nozzle is switched back on.
•
The OUT output is set once a workpiece is picked up securely, based on the vacuum value. This en-
ables the further handling process.
6.3 Depositing the Workpiece/Part (Blowing Off)
In blow off mode, the vacuum circuit of the ejector is supplied with compressed air. This ensures that the
vacuum drops quickly, allowing the workpiece to be deposited quickly.
During blow off, [

The ejector provides two blow off modes for selection:
•
Externally controlled blow off
•
Internally time-controlled blow off
6.4 Operating Modes
6.4.1 Automatic Operation
Once the ejector is connected to the power supply, it is ready for operation and enters automatic opera-
tion mode. This is the normal operating mode, in which the ejector is operated by the system controller.
The operating mode may be changed from automatic to manual mode using the buttons.
The ejector is always parameterized in automatic mode.
