FRONT PANEL OVERVIEW
CHAPTER 4: INTERFACES
The front panel also contains a full-speed USB port that is dedicated for communications
with a PC running the EnerVista software.
No settings are entered on the front panel; use the software instead.
Front panel interface operation
The front panel interface is a color TFT panel with pushbuttons for menu navigation and
dedicated pushbuttons for control functions. This display provides convenient access to
operational data generated by the D90
Plus
. It also enables local control of power system
devices that are connected to the IED.
The control pushbuttons are shown only in the control menu. Otherwise, the menu
navigation pushbuttons will be shown. The number of control pushbuttons is dependent
on the number of disconnects and breakers in the selected mimic diagram.
