5.3 Operating Modes
If the ejector is connected to the supply voltage, it is in automatic mode and ready for operation. This is
the normal operating mode, in which the ejector is operated by the system controller.
In addition to automatic operation, you can also use the keys on the ejector to change the operating state
and switch to manual mode.
The ejector is always parameterized in automatic mode.

The three keys on the foil keypad are used for operation and setting the parameters. If no parameters are
set, the ejector is in display mode. The current vacuum is displayed.
If settings are changed, undefined states of the system may occur for a short time (for approx. 50 ms).
