Section 2 Operation
2.1 Introduction
Red and green LEDs on the transfer switch controls
indicate which sources are available, show which
source is connected to the load, and flash to indicate
fault conditions. Pushbuttons allow you to start and stop
the generator set (with or without transferring the load)
and set the exercise timer. See Figure 2-1.
The transfer switch uses factory-default settings for time
delays, voltage and frequency pickup and dropout, and
other system settings. An optional accessory board
allows changes to the time delays and exerciser settings
and provides connections for remote test and remote
exercise inputs. See Section 4.1 for information on the
accessory board.
2.2 Pushbuttons and Indicators
Figure 2-1 identifies the controller pushbuttons and LED
indicators.
The LEDs light steadily or flash to indicate different ATS
conditions as shown in Figure 2-2. See Section 2.5 for
more information on fault conditions.
