Reporting Characteristics
■
An INFORMATION condition is the least severe of all the condition reports.
■
When only an INFORMATION condition is active, the audible alarm sounds
once per alarm cycle as shown in
Error Queue
The EMU maintains an internal error queue for storing error conditions. Each
error condition remains in the error queue until the problem is corrected, or for at
least 15 seconds after the error is reported. This ensures that when there are
multiple errors or a recurring error, each can be displayed. Each entry in the error
queue can be displayed using a combination of the top and bottom pushbuttons.
Each error entry in the queue contains the element type, the element number, and
the error code.
Correcting the error removes the associated condition from the error queue.
Replacing the EMU will also clear the error conditions.
The order in which the EMU displays the error queue information is based on two
factors:
■
The severity of the error
■
The time the error occurred
The most severe error in the queue always has precedence, regardless of how long
less severe errors have been in the queue. This ensures that the most severe errors
are displayed immediately.
Note:
When viewing an error, the occurrence of a more severe error takes precedence
and the display changes to the most severe error.
The earliest reported condition within an error type has precedence over errors
reported later. For example, if errors at all levels have occurred, the EMU displays
them as follows:
1. UNRECOVERABLE errors in the sequence they occurred.
2. CRITICAL errors in the sequence they occurred.
3. NONCRITICAL errors in the sequence they occurred.
4. INFORMATION conditions in the sequence they occurred.
