EMU Error and Fault Status Reporting
The EMU processes subsystem status reports, and when there is an error
condition, notifies the user of the problem using the EMU audible alarm and the
status LEDs (system, temperature, power, blower) located on the EMU front
panel (see Figure 4–2).
Whenever the audible alarm sounds, the user should check the EMU status LEDs
to determine the problem.
CAUTION
Should the audible alarm sound, but the status
LEDs not indicate an error condition, it possible
that the error condition no longer exists. However,
you should always check the controller error log to
verify the error condition no longer exists.
The EMU reports the system status, to include error conditions, to the controller
which records this information in the error log and displays it on the controller
console.
