Application Firmware.
Application Firmware missing, or Application CRC mismatch. The user

Controller Fault LED
The Controller Fault LED indicates a number of conditions.
Power On
When power is first applied to the board, the Controller Fault LED is turned ON by the
controller hardware. This is a temporary state and the LED will turn OFF after the
controller has powered up. If there is an error condition in the controller, the LED will
remain On.
Firmware Download
When the downloadable firmware is initialized, it takes control of the Controller Fault LED
and continues to drive the LED on. The LED will remain ON (not blinking) until the board
completes diagnostics with no fatal errors. If a fatal error occurs, the Controller Fault LED
will remain on. It will take approximately 6 seconds to complete level 0 diagnostics.
Controller Failure
A timeout timer (watchdog timer) also turns ON the Controller Fault LED if it does not get
serviced periodically by the firmware, indicating that there has been a catastrophic
controller failure. If this error happens, contact a trained service representative to upload
new firmware.
