Front-Panel Operations
Front-Panel Layout
Pressing the ESC pushbutton reverts the LCD display to the previous screen.
Pressing ESC repeatedly returns you to the
MAIN MENU. If a status warning,
alarm condition, or event condition is active (not acknowledged or reset), the
relay displays the full-screen status warning, alarm screen, or trip event screen
in place of the
MAIN MENU.
Screen Scrolling
The front panel has two screen scrolling modes: autoscrolling mode and
manual-scrolling mode. After front-panel time out, the LCD presents each of
the display screens in this sequence:
➤ One-line diagram
➤ Any active (filled) alarm points screens
➤ Any active (filled) display points screens
➤ Enabled metering screens
The relay displays enabled metering screens in the order listed in Table 7.2.
(see Figure 7.18 for samples of the metering screens). This sequence
comprises the
ROTATING DISPLAY.
Use the front-panel settings (the SET F command from a communications
port or the front-panel settings in
ACSELERATOR QuickSet) to access the
metering screen enables. Entering a Y (Yes) for a metering screen enable
setting causes the corresponding metering screen to appear in the
ROTATING
DISPLAY
. Entering an N (No) hides the metering screen from presentation in
the
ROTATING DISPLAY. Figure 7.4 shows a sample ROTATING DISPLAY
consisting of an example alarm points screen, an example display points
screen, and the two factory-default metering screens, RMS_I and FUND_VI
(the screen values in Figure 7.4 are representative values).
