TB8100 Service Kit User's Manual
The Auxiliary output box has an LED that indicates the status of the auxiliary
power or battery charging output.
LED Text Description
Green On The standby DC supply has been turned on. The PMU is
providing only 10 W of power to the exciter.
Red Off There is a fault. This could be because there has been a
current overdraw and the fuse is blown. On cooling, the
fuse will automatically reset.
Gray Off No auxiliary power supply unit is fitted or the PMU has
turned the output off.
The box label indicates the voltage that the auxiliary power submodule is
designed to produce (12, 24, or 48 V).
The Output Current gauge shows how much current the PMU is supplying to
the rest of the BSS.
