3.2.3 LCD Display
The controller is equipped with a two-line x 16-character backlit digital display with adjustable contrast. When the generator is
running, the controller automatically scrolls through the displays shown in Figure 33. When the system is in standby mode and
the controller is in AUTO, the screens shown in Figure 33 are displayed.
When a fault or warning condition exists, the controller will show the corresponding message. See the Fault section for more
information about faults.
Controller menus display power system information, including status information for the engine, generator, and optional RBUS
accessories, exercise settings, and event history. Some menus allow changes to the controller settings. See the related sections
in the manual for menu diagrams.
The display contrast is adjustable. Navigate to the Genset System menu and step down to the Contrast screen. Press the Select
button, and then use the up and down arrow buttons to adjust the contrast. See the related sections in the manual, Changing
Settings, and Genset System Menu.
The display backlight turns off after about a minute of no activity. The backlight turns on when a button is pressed or when the
generator set starts.
