ABB UNO-2.0-I-OUTD Product Manual page 75

We advise changing the activation voltage only if really necessary and to set it to the correct
value: the photovoltaic generator sizing tool available on the ABB website will indicate whe-
ther Vstart needs changing and what value to set it at.

5. Value
This section of the menu allows you to set the name of the currency
and the value of 1 kWh of energy produced. Setting these parameters
correctly allows the actual earnings/savings achieved by the system to
be displayed.
• Nome: sets the desired currency (default is Euro)
• Val/KWh: indicates the cost/incentive for 1 kWh in the chosen currency
(default is 0.50).
6. Time
Allows you to set the current date and time (not counting summer time)
7. Language
Allows you to set the language you prefer for the menus
8. Vstart
This section of the menu allows you to set the Vstart voltage (for the
two channels separately if they are configured independently) to suit the
system requirements.
9. Autotest
This section of the menu is available only for the Italian country standard.
Refer to the section on this topic in the manual.
10. Alarm
This section of the menu allows you to set the activation status of a relay
(available either as contact normally open – N.O. – or as contact normal-
ly closed – N.C.).
This contact can be used, for example, to: activate a siren or a visual
alarm, control the disconnect device of an external transformer, or control
an external device.
The relay can be set to switch in 4 different modes:
• Production (display text "PRODUCTION")
The relay is activated (state: switched) whenever the inverter connects
to the grid; as soon as the inverter is disconnected from the network (for
whatever reason that caused disconnection), the relay is in its resting
position
