For both configurable relay operating modes "ALARM" and "ALA". CONF." the following con-
siderations apply:
If the alarm condition is persistent, the alarm contact cyclically switches from its resting state
to its activated state.
In the presence of W003 signalling (Grid Fail – Network parameters out of tolerance), 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 "Vac Absent") the alarm contact remains
in its resting position.
• 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.

• Configurable alarm with reset at the end of the alarm signalling
process (display text "Alarm Conf.")
The relay is activated (state: switched) whenever an error is present
(code Exxx) or a warning (code Wxxx) from those selected from the list in
the dedicated submenu. 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.
