7 - Operation

• 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.
