Front-Panel Operations
Front-Panel LCD Default Displays
Use the front-panel settings (the SET F command from a communications port
or the Front Panel settings in
ACSELERATOR QuickSet SEL-5030 Software) 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
ROTAT-
ING DISPLAY
. Entering an N (No) hides the metering screen from presentation in
the
ROTATING DISPLAY. Figure 4.1 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 4.1 are representative values).
