7 - Operation
For the configurable 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.
• Alarm-Contact (crepuscolar):
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.
• Alarm-Contact (alarm ALL - latch):
The relay is activated (status: switched) whenever an error (code Exxx)
or a warning (code Wxxx) is present. When the inverter returns to the
normal operating state and reconnects with the grid, the contact returns
to its position of rest.
