Do not turn the flow control screw beyond its stops! Due to technical
reasons, a minimum volume flow of approx. 20% is always required.
The blow-off volume flow can be set to a value between 20% and 100%.
Commissioning
The ejector may only be commissioned after it has been installed in the machine/
system for which it is intended.
First-time commissioning
1. Make sure that all electrical and pneumatic connections of the ejector are
correctly connected and are firmly fitted.
2. Enter the required menu settings (basic settings, configuration menu, system
menu, and user menu).
3. Switch on the operating voltage.
4. Switch on the operating pressure.
Recommissioning after a downtime
1. Make sure that all electrical and pneumatic connections of the ejector are
correctly connected and are firmly fitted.
2. Switch on the operating voltage.
3. Switch on the operating pressure.
A typical handling cycle is divided into the three steps of suctioning, blowing off and
idle state. In order to check whether sufficient vacuum has been built up, output 2 is
monitored during suctioning.

Adjusting the software menus
The menu is operated using four buttons. Settings are adjusted using the software
menu. The operating structure is split into settings for the home menu and settings
for the configuration menu. For standard applications, adjusting the ejector's
settings in the home menu will suffice. An advanced configuration menu is available
for applications with special requirements.
When settings are changed, undefined states may occur in the system for
short periods of time (for around 50 ms) under certain circumstances.
Vacuum display
Outside of the menus, the ejector is in display mode and displays the current
vacuum.
If there is overpressure in the vacuum circuit, the display "-FF" appears. This
normally occurs in the "Blow-off" operating state.
If the vacuum value is too high (outside of the measurement range), the display "FFF"
appears.
