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 in the following order:
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.
Error condition report format
Each EMU detected condition generates a condition report containing three pieces of information.
• Element type The first two-digit hexadecimal display defines the element type reporting the
problem. The format for this display is e.t. with a period after each character. Valid element
types are 0.1. through F.F.
• Element number The second display is a two-digit decimal number that defines the specific element
reporting the problem. The format for this display is en. with a period after the second character.
• Error code The third display is a two-digit decimal number that defines the specific error code.
The format for this display is ec without any periods.
For detailed information about each condition report, including recommended corrective actions.
Navigating the error condition display
When an error condition occurs, the alphanumeric display changes to Er and the error menu is active.
The buttons are used to display the error condition values.
Perform the following procedure to display error conditions.
Figure 20 illustrates the sequence for
displaying error conditions.
1. With Er in the display, press and hold the top push button until the first element type is displayed.
The most severe error in the queue will be displayed.
2. Release the top push button when the element type is displayed. The element type has both decimal
points lit.
3. Press and release the top push button to display the element number. This display has only the
right decimal point lit.
4. Press and release the top push button again to display the error code. This display has no decimal
points lit. Repeated press/release operations will cycle through these three values.
5. Press and hold the top push button from any of the three display states to move to the element
type for the next error condition in the queue.
6. Use the top push button to display the values for the error condition.
7. When all error conditions have been displayed, press and release the bottom push button to return
to the Er display.
