The display has two lines, each with 16 characters. The first line shows the menu number and the menu
name, or the name of the parameter where applicable. The menu name is supplemented or the added
text is displayed (e.g., parameter value) in the lower line, if required.
Switching operating levels
If the password is invalid, the Sunny Island does not switch to the installer level. In this case,
recalculate and re-enter the installer password as described in this section.
The installer level is switched back to the user level if:
• the Sunny Island is switched off and on again.
• specific parameters are entered (e.g., the "510.01 InvRs" parameter) that cause a
restart.
• an incorrect password is entered.
• no activity takes place within 5 minutes.
