LED Messages

This section discusses the meaning of the various messages and codes that may be dis- played on the LED display during normal operation and fault conditions.

Diagnostic LED

The AX500 features a single diagnostic LED which helps determine the controller’s operat- ing mode and signal a few fault conditions. The LED is located near the edge of the board, next to he 15-pin connector.

Normal Operation Flashing Pattern

Upon normal operation, 1 second after power up, the LED will continuously flash one of the patterns below to indicate the operating mode. A flashing LED is also an indication that the controller’s processor is running normally.
