8 Graphical Display and Operation Unit
8.1 General
The graphical Display and Operation Unit (DOU) is integrated into
the front of the solar inverter. It serves to signal and visualise unit
data and to control the inverter system. The DOU consists of a
display unit with 3 LEDs, a graphical LCD and an operating panel
with 5 keys.
The global unit status can be read from the LEDs (1). An acoustic
signal generator stresses the urgency of critical system statuses.
The graphical LCD shows equipment statuses and measured val-
ues using symbols and plain text. You can control and parametrise
the unit using menus which are protected by a password.
The DOU is operated using 4 display keys, to which alternating
functions are assigned, and one ENTER key. The key functions
that are currently active are shown on the LCD in the form of sym-
bols.
