3.1.2 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, [
-FF
] is shown on the display.
The ejector provides three blow-off modes for selection:
•
Externally controlled blow-off
•
Internally time-controlled blow-off
•
Externally time-controlled blow-off
3.1.3 Product Highlights
The current vacuum level can be shown on a three-digit display. LEDs are used to indicate switching
points H1 and H2 and the current process status ("Suction" or "Blow-off"). There are also four buttons for
operation.
Monitoring the system pressure: The ejector with the built-in pressure sensor (-PC- variant) monitors the
system pressure in addition to the system vacuum.
It has an IO-Link class B interface; this will be referred to as the "IO-Link" for the remainder of this docu-
ment.
In IO-Link mode, the ejector has an energy and process control (EPC) for monitoring the vacuum circuit.
All of the settings, parameters and measurement and analysis data are made available centrally via IO-
Link.
Additionally, much of the information and the status reports for the ejector can be accessed using wire-
less communication with NFC (Near Field Communication).
3.2 Operating Modes
If the ejector is connected to the supply voltage, it is ready for operation. This is the normal operating
mode, in which the ejector is operated by the system controller.
The ejector is parameterized via the available menus or via IO-Link.
The following operating modes are available during the setup process:
•
Setting Mode
•
Manual Mode
