Pump operation

Settings on pump

Carry out settings by turning and pressing the operating button. Turn the operating button to the left or right to browse the menus or configure settings. A green focus indicates navigation in the menu. A yellow focus indicates a configuration of settings.

Green focus: Navigation in menu.
Yellow focus: Change settings.

Turn : Menu selection and parameter setting.
Press : Activation of menus or confirming settings.

Press the Back button (pos. 3.5 in section “Description of operating elements”) to change the focus back to the previous focus. Consequently, the focus moves one level further up in the structure or to a previous setting.

Pressing the Back button after having changed a setting (yellow focus) without confirming the changed value returns the focus to the previous focus. The adjusted value will be discarded. The previous value remains unchanged.
If the Back button is pressed for more than 2 seconds, the Home screen opens and the pump can be operated from the main menu.

NOTICE

If there are no warning or error messages, the display on the control module will switch off 2 minutes after the last time it was operated.

• If the operating button is pressed or turned again within 7 minutes, the previously exited menu will appear. You can continue to configure settings.

• If the operating button is not pressed or turned for more than 7 minutes, any unconfirmed settings will be lost. Pressing the button again opens the Home screen on the display and the pump can be operated from the main menu.

Initial settings menu

The settings menu will appear in the display during initial commissioning of the pump.

Initial settings menu

If necessary, press the Context button and go to the Language menu to change the language.

The pump runs in factory setting when the initial commissioning menu is open.

If you do not want to make adaptations to the pump in the initial commissioning menu, select “Start with factory settings” to quit the menu. The Home screen opens on the display and the pump can be operated from the main menu.

After reinstallations we recommend venting the rotor chamber. For this purpose, activate “Start venting”. A venting routine starts in the background. Other settings can be configured while venting is active.

Open the “First settings” menu to configure the most important initial commissioning settings (e.g. language, units, control mode and setpoint) to adapt the pump to the required application. The chosen initial settings are confirmed by activating “Finish initial settings”.

Quit the Initial commissioning menu to open the Home screen on the display and operate it from the main menu.
