8. TROUBLESHOOTING

This section describes the LED states and provides possible trouble conditions of the PAD-3.

8.1 LED INDICATORS

Light-emitting diodes (LEDs) indicate fault and normal conditions. The seven LEDs indicate a fault
condition in one of the circuits (either outputs 1 through 4, auxiliary power, ground fault, or battery). A fault
condition in the LEDs corresponding circuit will turn on the LED (labeled on the board). The POWER LED
will normally be on and turn off to indicate an AC Fail condition. See Figure 2-2 for locations of LEDs.
Their functions are as follows:
