Troubleshooting Using the Automatic Gas Console
Messages Screen
If all of the status LED’s are illuminated but the Spirit system still has a
problem, switch to the messages screen on the automatic gas console
(see Section 5 for specific instructions on switching to the messages
mode). The gas console may display information that is useful in
pinpointing the problem. While the automatic gas console is displaying an
error message, the power supply microprocessor displays an error code
by blinking LED22 on and off to indicate that an error has occurred. The
number of blinks can be counted to determine which error has occurred.
The following chart lists the errors and the corresponding number of
blinks.
