10. Alarm
This section of the menu allows you to set the activation status of a relay
(available either as contact normally open – N.O. – or as contact normally
closed – N.C.).
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 external device.
The relay can be set to switch in 4 different modes:
• Production (display text "PRODUCTION")
The relay is activated (state: switched) whenever the inverter connects
to the grid; as soon as the inverter is disconnected from the network (for
whatever reason that caused disconnection), the relay is in its resting
position
No
• Alarm with reset at the end of the alarm signalling process (display
text "ALARM"):
The relay is activated (state: switched) whenever an error is present
(code Exxx) on the inverter; this does not apply to warnings (Warning
– code Wxxx). The alarm returns to its resting position when the alarm
signal ends, i.e. before 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.
