3.2.2 LED Indicators
LEDs above the RUN, OFF, and AUTO buttons indicate the mode of operation as shown in Figure 16.
Load indication LEDs indicate the load on the generator set. A steadily lighted LED indicates that the load on the generator set
is greater than or equal to the level label for that LED. The next LED flashes and stays on for a longer time as the load increases.
LED
LED Operation
RUN
Lights when the generator set has been started locally by pressing the RUN button. Remote start and stop commands are
ignored.
OFF
Lights for 2 seconds, then flashes every 2 seconds when the generator set and controller are off. Remote start/stop
commands have no effect. The exercise cycle will not run.
In Auto mode, OFF LED flashes quickly to indicate a fault shutdown. Attention required. Identify and correct the fault
condition before resetting the controller.
AUTO
Lights when the generator is in automatic (standby) mode. Generator set will respond to engine start and stop commands
from the controller (for example, exercise start and stop commands) or an ATS. Time delays operate as described in
Section 2.4.
25% load
LED flashes and stays on longer as load increases from 1% to 25%.
50% load
LED flashes and stays on longer as load increases from 26% to 50%.
75% load
LED flashes and stays on longer as load increases from 51% to 75%.
100% load
LED flashes and stays on longer as load increases from 76% to 100%.
Figure 16 VSC Controller LED Operation
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 17. The VSC controller measures and displays
the average DC output voltage on the auto-scrolling display. When the system is in standby mode and the controller is in AUTO,
the screens shown in Figure 17 are displayed.
When a fault or warning condition exists, the controller will show the corresponding message. See 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.
