This area, which is composed by the display and the UP, DOWN, ENTER and ESC buttons, allows the visualization
(and the modification) of the setpoints, the status of the grid and of its protections, the electrical measures, the digital
input/output signals and the history logs. The navigation is organized in menus and pages.
Keep the UP or DOWN buttons pressed for more than 1 second to move across the menus. Press the UP or DOWN
buttons for less than 1 second to move across the pages in the selected menu. In PROGRAM and HISTORY menus,
use the ENTER button to access sub-menus, press the ESC button to go back to the upper menu.
In PROGRAM menu, use the ENTER button to start the editing of a setpoint, press UP or DOWN buttons to change
its value, confirm with ENTER or abort with ESC. Using UP or DOWN buttons together with SHIFT allows to change
the value of the setpoint x10.
Depending on the environmental lighting conditions, a contrast adjustment may be required to view the display
correctly. Press the buttons sequence SHIFT + DOWN to decrease the contrast and SHIFT + UP to increase it.
This area, composed by the RESET button and the TRIP led, allows to manage the plant.
The TRIP led is activated whenever a grid protection trips. It is deactivated when all the grid protections are reset.
You can select the auto-reset mode for the grid protections, ore you can manually reset them by pressing the RESET
button. While the RESET button is pressed, the controller switches on the TRIP led (lamp test).
The controller can also activate anomalies not related to the grid (for example low/high power supply voltage): in this
case a message is shown on the display and the internal horn is activated. Press the ENTER button to silence the
internal horn and to “acknowledge” the anomaly. Pres the RESET button to reset the anomaly.
WARNING! Assigning an incorrect value to one or more setpoints can cause malfunctions or damages
to things and/or people. The setpoint changes must be carried out only by skilled personal. The setpoints
can be protected by password.
To adjust the setpoints, it is necessary to enter the PROGRAM menu (page P.XX).
The editing of the setpoints can be protected by three different PASSWORD levels, which are listed in order of
priority: 1. Manufacturer password.
2. Installer password.
3. User password.
