• Crepuscolar - display text "Alarm-Contact (crepuscolar)":
The relay is activated (status: switched) as soon as the inverter input
voltage exceeds the activation voltage set.
The relay switch to 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.
• Alarm Latch - display text "Alarm-Contact (alarm ALL - latch)":
The relay is activated (status: switched) whenever an error (code Exxx)
or a warning (code Wxxx) is present (see the table below). When the in-
verter returns to the normal operating state and reconnects with the grid,
the contact returns to its position of rest.
