3.1.3 Pneumatic Air Saving Function
The ejector includes a pneumatically operated air saving function. When compressed air is applied to com-
pressed air connection 1
(> See ch. (See chap. Ejector structure)) , the ejector automatically controls the
vacuum. When the set deactivation value A is reached, the ejector switches off the Venturi nozzle. If the
system vacuum drops below the activation value E due to leaks, the Venturi nozzle is switched back on.
The following diagram shows the air saving function.
The output is set to "on" when switching point SP1 is reached. If the reset value rP1 is not reached, the
output is set to "off."

3.2 Operating Modes
The vacuum switch can be operated in two operating modes. Users can choose between direct connection
to discrete inputs (standard I/O = SIO mode) or connection through the communication line (IO-Link class
A).
If the device is connected to the supply voltage, it is ready for operation. This is the normal operating
mode, in which the vacuum switch is operated by the system controller. A differentiation is made be-
tween SIO mode and IO-Link mode.
The vacuum switch is parameterized via the available menus or via IO-Link.
