7 - Operation
• Alarm with reset at the end of the alarm signalling process "Alarm"
The relay is activated (status: switched) whenever an error (code Exxx)
or warnings related to grid parameters out of range (Warning – codes
W003, W004, W005, W006, W007) are present on the inverter. 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.
Alarms for which the relay is activated

E007 E009 E010 E011 E012 E013

E057 E058 E077 E078 E081 E084
E089 W003 W004 W005 W006 W007
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.
• Congurable alarm with reset at the end of the alarm signalling
process "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.
