7. Troubleshooting
Light-emitting diodes (LEDs) indicate fault conditions. This section describes the LED states
and provides trouble condition details.
7.1 LEDs
The eight LEDs indicate a fault condition in one of the circuits (either outputs 1 through 4,
auxiliary power, earth fault, low AC, or battery). A fault condition in the LED's corresponding
circuit will turn on the LED (labeled on the board). Their functions are as follows:
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.
See page 11 for locations of LEDs.
