• PRODUCTION: The relay is only activated when the inverter is connected
to the grid.
For instance, if the N.O. (or N.C.) contact is chosen, the contact will remain open
(closed) as long as the inverter is not connected to the grid; once the inverter is
connected to the grid and starts to export power, the relay switches its status and closes
(opens). When the inverter is disconnected from the grid, the relay contact returns to
its rest position, i.e. open (closed).
• FAULT: Triggers relay activation (code E).
For instance, if the N.O. (or N.C.) contact is chosen, the contact will remain open
(closed) as long as the inverter does not show a fault (IT DOES NOT SWITCH IN
THE CASE OF A WARNING or Code W); once the inverter shows a fault, the relay
switches its status and closes (opens). The contact stays switched compared to its rest
condition until normal operation in parallel with the grid is restored.
To select the alarm contact's operational mode, access the alarm submenu from the
settings menu, select the desired operational mode with the UP and DOWN arrows
and press the ENTER key to confirm the selection.
5.4.6.10 Remote Control
This control is used to disable the inverter manual switch-off. Set as follows:
- ENABLE, to activate the manual ON/OFF function
- DISABLE to disable manual ON/OFF function, so that Aurora operation will only
depend on external solar radiation.
