Troubleshooting
Light-emitting diodes (LEDs) indicate fault conditions. This section describes the LED
states.
6.1 LEDs
The eight LEDs indicate a fault in one of the circuits (either NACs 1 through 4,
auxiliary power, earth fault, low AC, or battery). A fault in the LED's corresponding
circuit will light the LED (labeled on the board). Their functions are as follows:
See Figure 4-2 for locations of LEDs.
LED Color Description
OUT1 Yellow When ON, output circuit 1 is in trouble or in an overcurrent state.
OUT2 Yellow When ON, output circuit 2 is in trouble or in an overcurrent state.
OUT3 Yellow When ON, output circuit 3 is in trouble or in an overcurrent state.
OUT4 Yellow When ON, output circuit 4 is in trouble or in an overcurrent state.
AUX Yellow When ON, the auxiliary power output is in an overcurrent state.
FLT Yellow When ON, an earth ground fault on the unit exists.
BATT Yellow When ON, a low battery condition exists.
AC Green When OFF, there is no AC power to the unit. Under normal conditions, this LED
is ON to indicate the presence of AC power.
