7 - Operation
Local I/O Manager
In the
Local I/O Manager
sub-menu it’s possible to enable the ma-
nagement of power flows in order to optimize self-consumption or
avoid feeding power to the grid (this features will work only on inverter
equipped with UNO-DM-COM KIT (-X models) or UNO-DM-PLUS-COM
ETHERNET KIT (-E models)).
This section of the menu allows you to set the activation status of a relay
(available either as contact normally open – N.O. - and as a normally
closed contact -N.C.) and to configure customised alarm conditions.
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 ex-
ternal device. A little description of the alarm type (e.g. “alarm lamp”) is re-
quired.
Relay switching can be set in 9 different modes using the submenu
Set
Alarm Type
(For the “Alarm Conf.”, “Al. Conf. Latch”, “Al. Conf. Ext.”,
“GoGo Rel(Auto)” and “GoGo Rel(Slave)” it is possible to configure
customised alarm conditions through the submenu
Alarm Config
and
GoGo Config
):
• Alarm Production - display text “Alarm-Contact (Production)”
The relay is activated (status: switched) whenever the inverter connects
to the grid; as soon as the inverter is disconnected from the grid (for
whatever reason that caused disconnection), the relay is in its resting
position.
• Alarm with reset at the end of the alarm signalling process - dis
-
play text “Alarm-Contact (alarm ALL - no-latch)”:
The relay is activated (status: switched) whenever an error (code Exxx)
or warnings related to grid parameters out of range (Warning – codes
W003, W004, W005, W006, W007) are present on the inverter. The
alarm returns to its resting position when the alarm signal ends, i.e. be-
fore the inverter checks the grid parameters after the alarm state. This
is because grid control state is not an alarm state but a state of normal
operation.

In the presence of W003, W004, W005, W006, W007 signalling, the alarm contact switches
to then reset itself at the end of the alarm signal. This means that during the absence of grid
voltage (display message “Missing Grid”) the alarm contact remains in its resting position.
