10.2 Changing Parameters
Using the up and down arrow buttons, you navigate through a selected menu to view or change a
parameter, for example. When the relevant parameter is displayed, you can read off its present value.
An arrow next to the value indicates that the parameter can be changed.
If you press <ENTER>, the arrow begins to blink and you can use the up and down arrow buttons to
change the value of the "221.02 BatCpyNom" parameter.
As soon as the desired value appears on the display, press <ENTER> to save the new value.
Then select Y(es) or N(o) by pressing the up/down arrow buttons to accept or reject the changes.
Press <ENTER> again in order to finish the process and continue with other modifications.
The Sunny Island displays a corresponding message for parameters that can only be changed in
standby mode or require a different password level.
Increments (speed)
The increment size (speed) of the change increases if you hold the button pressed down.
Changing parameters
Note that some parameters can only be changed when the device is in standby mode
(see Section 19.2 "Adjustable Parameters", page 166). All menu items that can only be
changed by the installer using a password are shaded in gray in the parameter list.
Display Description
Incorrect password level, you cannot make any
