Pushing the keys and changes between different display topics.
Figure 9. LC-Display: Indication of measured values
The display [1] shows the initial state (basic display). The plain text of the basic display becomes visible

If no inverter is registered, display [4] is not available.

If more than one inverter is registered, it is possible to call the parameters (input current,
output current and status) of all connected inverters in succession by pressing “ENT”.
The inverter number is shown in the first line of the display. Press “ESC” to go one step back.
The display automatically will revert to display [1] if no key is pressed for a period of more than
30 seconds.

switched “inactive” in the customer menu (see the diagram “customer menu”).
