Self-Test Failure Codes
The Petrel-X performs a self-test every time it is turned ON, either by applying power or turning
it ON with the magnet switch.
If any of the self-test criteria fail, the Petrel-X will flash its
RED
LED in an error code pattern to
indicate which criteria failed. If multiple criteria fail, only the highest priority failure code will be
displayed. These patterns are in Morse code (short and long flashes), writing the first letter of
the criteria that failed
The table below shows the failure code patterns, with the highest priority criteria at the top.
