Error Condition Reporting
The E MU constantly monitors enclosure operation and notifies you of co n ditions that could affect
operation. When an error condition is detected, the following action is taken:
• The EMU alphanumeric display is changed to Er. A condition report has precedence over all
other displays.
• The audible alarm sounds (if it is not disabled) .
• The error is stored in the error queue.
• The error is passed to the controllers for processing and display by Command View EVA.
