The graphical display and operation unit (DOU) is integrated in the
front of the UPS housing. It serves to signal and display UPS unit
data and to control and parameterise the UPS 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 3 LEDs. An acoustic
signal generator stresses the urgency of critical system statuses.
The graphical LCD shows system statuses and measured values
using symbols and plain language. The unit can be controlled and
parameterised using menus which are protected by a password.
The DOU is operated using 4 display keys, to which several functions
are assigned, and one ENTER key. The currently active key functions
are shown on the LCD as symbols.
