FRONT PANEL INTERFACE
Rolling mode
After a user-defined period of inactivity, the graphical front display rolls among up to 10 user-selected pages. The roll-to-
pages are selected in the EnerVista software, with the defaults being the product information page. Each page displays for
less than five seconds. Also, the display backlight intensity is lowered after a configurable period to a user-defined level (0,
10, 20, or 30%); lower intensity extends the life of the display.
Configure rolling mode in the software under Settings > Product Setup > Graphical Panel > Rolling Mode.
Operation works as follows:
• Press the Home pushbutton or ESCAPE pushbutton twice to cancel rolling, restore full backlight intensity, and return
to the Home page
• Press the ENTER, ESCAPE, or a pushbutton to pause rolling once and restore full backlight intensity
Rolling is disabled by setting the delay to 0.
The following buttons display at the top of the window:
• Save — Updates the connected device if online or the open setting file if offline with changes made
• Restore — Undoes changes that have not been saved
• Default — Changes all rolling mode settings to their factory default values
• Reset — Displays factory default values. Previous changes are not lost unless you save the reset window.

Single-line diagrams
A single-line diagram, or mimic diagram, is a line drawing of elements in an electrical system. The graphical front panel
displays up to five single-line diagrams. Each can be configured to show the arrangement of a portion of the power
system, the status of circuit breakers and of ground and disconnect switches, user-programmable pushbuttons, and
metering and status values. Each also enables control of the displayed power system devices.
One diagram is provided by default, single_bus_line_dsc.mif, which can be modified.
Configure the diagrams under Settings > Product Setup > Graphical Panel > Single Line Diagram Editor.
Each single-line diagram page has a user-configurable name that appears in the header and in the footer Tab pushbutton
label. Factory default names are SLD 1 to SLD 5. Pages that have no configured content have a blank Tab pushbutton
label, and the Tab pushbutton does nothing. The label for the current page has a blue background.
