7.5.2.9 DIGITAL OUTPUTS
In the Digital Outputs menu it’s possible to set the activation
status and to configure customized alarm conditions of the two
configurable relays related to “ALARM and AUX” terminal block (33)
(refer to “Configurable Relay connection (ALARM and AUX)”
paragraph to know how to connect to these terminal block).
This contact can be used, for example, to activate a siren or a visual
alarm, control the disconnect device of an external transformer, or
control an external device.
Relay switching can be set in different modes by clicking on the
setting icon
: With “Output active filter” you can select the list of
events for which the relays switch.
The available operating mode are:
• Production
The relay is activated (status: switched) whenever the inverter
connects to the grid; as soon as the inverter is disconnected from
the grid (for whatever reason that caused disconnection), the
relay is in its resting position.

• Alarm ALL - no-latch
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 contact 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.

In the presence of W003, W004, W005, W006, W007 signalling,
the alarm contact switches and 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.
