The backlighting lamp is managed by the controller, which switches it off if no button is pressed
within a configurable time (P.0492). To turn it back on, just press any button (it is advisable to
use the
ESC/SHIFT
button which, when alone, does not perform any operation). It is possible
to disable automatic shutdown by setting parameter P.0492 to 0.
By using parameter P.0493, it is possible to force the lamp always on when the inverters for
the renewable sources are running.
For a correct view of the display, depending on the ambient temperature conditions, the
contrast adjustment may be necessary.
Press the
ESC/SHIFT + ◄
button in sequence to decrease the contrast (lighten), press the
ESC/SHIFT + ►
button to increase the contrast (darken).
By factory default, the controller shows information on the display using a blue background
colour. However, this behaviour can be changed using parameter P.0499:
•
P.0499 = 0: blue background.
•
P.0499 = 1: black background.
•
P.0499 = 2: white background.
The colour of the messages depends on the background colour selected and the type of
information displayed.
The display has different viewing modes, each consisting of several pages.

Generally, the navigation between the modes is done using the ▲ and ▼ buttons. To view the
pages within a mode, use the ◄ and ► buttons. Some modes are organized in menus (P.XX
and H.XX): in these cases, to view the pages, it is necessary to press the
ACK/ENTER
button
and then the ▲ and ▼ buttons.
In the event that the ▲ and ▼ buttons are to be used to manage specific functions within a
page, the
ACK/ENTER
buttons are required to activate these functions, the
ESC/SHIFT
buttons to deactivate them.
