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.

Power On LED

The AX1500 features an LED that comes on whenever the board is powered on. When lit, this LED indicates that the on-board DC/DC converter is functioning. It provides no infor- mation regarding the controller’s operation.

Diagnostic LED

The AX1500 features a single diagnostic LED which helps determine the controller’s oper- ating 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.
