• Congurable alarm with reset at the end of the alarm signalling
process (display text “Alarm (Conf.)”)
The relay is activated (state: switched) whenever an error is present
(code Exxx) or a warning (code Wxxx) from those selected from the list in
the dedicated submenu. The contact returns to its resting position when
the alarm signal ends, i.e. before the inverter checks the grid after the
alarm state. This is because grid control state is not an alarm state but a
state of normal operation.

For both congurable relay operating modes “Alarm” and “Alarm (Conf.)” the following con-
siderations apply:
• If the alarm condition is persistent, the alarm contact cyclically switches from its resting state
to its activated state.
• In the presence of W003 signalling (Grid Fail – Network parameters out of tolerance), the
alarm contact switches to then reset itself at the end of the alarm signal. This means that du-
ring the absence of grid voltage (display message “Vac Absent”) the alarm contact remains
in its resting position.
• In the presence of W002 signalling (UV Input – input voltage below the limit of operation),
the alarm contact switches to then reset itself at the end of the alarm signal. This means that
during the reduced input voltage (display message “Waiting sun”) the alarm contact remains
in its resting position.
• Crepuscular (display text “Crepuscular”)
The relay is activated (state: switched) as soon as the inverter input vol-
tage exceeds the activation voltage set.
The relay is in its rest position when the input voltage drops below 70%
of the activation voltage set.
This mode is useful for disconnecting any output transformers that could
have unnecessary consumption during the night.
