7 - Operation
3. Alarm Configurable - no-latch
The relay is activated (status: switched) whenever an error (code Exxx)
or a warning (code Wxxx) is among those selected from the list in the
dedicated submenu Alarm Config . The contact returns to its resting po-
sition 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 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.
4. Crepuscular
The relay is activated (status: switched) as soon as the inverter input
voltage exceeds the activation voltage set.
The relay is in its 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.
