Light-emitting diodes (LEDs) indicate fault conditions. Section 7 describes the LED states and provides trouble condition details. This section also describes how to remove and replace the 5499 control panel. |
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 (labled on the board). Their functions are as follows.
