A CRITICAL condition has precedence over NONCRITICAL and INFORMATION conditions, but does not
have precedence over UNRECOVERABLE conditions.
When this codition is the most severe active condition, the
audible alarm
sounds three times per alarm
cycle, as shown in
.
NONCRITICAL condition
A NONCRITICAL condition is less severe than an UNRECOVERABLE condition or a CRITICAL condition.
This condition occurs when one or more elements inside the enclosure have failed or are operating
outside of their specifications. The failure of these elements do not affect continued normal operation
of the enclosure. All devices in the enclosure continue to operate according to their specifications. The
ability of the devices to operate correctly may be reduced should other errors occur.
Early correction to prevent system degradation is recommended.
A NONCRITICAL condition establishes the following conditions:
•
An UNRECOVERABLE condition has precedence over this condition.
•
A CRITICAL condition has precedence over this condition.
•
This condition has precedence over INFORMATION condition.
•
When this condition is the most severe error active, the
audible alarm
sounds two times per
alarm cycle, as shown in
.
INFORMATION condition
An INFORMATION condition is the least severe of the condition reports and does not require immediate
correction. It advises you that a condition exists that does not reduce the capability of an element but
that could become more severe and require corrective action later.
When only an INFORMATION condition is active, the
audible alarm
sounds once per alarm cycle,
as shown in
Error queue
The EMU stores each condition report 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. The complete report is stored and you recall any report using a combination of
the top and bottom push-buttons. Correcting the error removes the condition report from the error queue.
Each report in the queue contains the element type, the element number, and the error code. To remove
information from this queue requires either clearing the error or replacing the EMU.
The EMU displays the error queue information based on severity level and time of occurrence.
NOTE:
When you are viewing an error, the occurrence of a more severe error takes precedence and the display
changes to the most severe error.
The most severe error in the queue always has precedence, regardless of how long less severe errors
have been in the queue.
This hierarchical display ensures that the most severe errors haveprecedence over less severe errors. The
earliest reported condition within an error type has precedence over errors reported later. For example,
if you have errors at all levels, 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.
