Diagnostic LEDs on the Base PC Board
The PC Board mounted at the mast Base has LED indicator lights useful for diagnostics for
circuits. Table 7-2 charts the colors of the relevant diagnostic LEDs for the various mast
positions. An example of the diagnostic LEDs showing the mast in the stowed position is shown
in Figure 7-1. These diagnostic LEDs can be used to help determine if an adjustment is
necessary, for example if D7 / D8 shows Yellow when the mast is supposed to be stowed. They
are also useful in assisting to determine when the switches have been properly adjusted.
