The relay is activated (status: switched) whenever an error (code Exxx)
or a warning (code Wxxx) is present from those selected from the list in
the dedicated submenu Output Activation Filter of the inverter display.
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.

If the alarm condition is persistent, the alarm contact cyclically switches from its resting state
to its activated state.

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.
In the presence of W003, W004, W005, W006, W007 signalling, the alarm contact switches
to then reset itself at the end of the alarm signal. This means that during the absence of grid

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.
