• Congurable alarm with reset at the end of the alarm signalling
process (display text “Alarm Conf.”)
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 Alarm Cong. 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.

For the congurable relay operating mode “Alarm Conf.”, the following considerations are
valid:
If the alarm condition is persistent, the alarm contact cyclically switches from its resting state
to its activated state.
In the presence of W002 signalling (Input UV – input voltage below the limit of operation),
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
voltage (display message "Missing Grid") the alarm contact remains in its resting position.
