Status Message Categories
Status Message
Categories
In terms of operator reaction, there are three categories of status messages (see
the summary on the following page):
• Status messages not requiring acknowledgment
• Status messages requiring acknowledgment
• Status messages requiring acknowledgment and intervention
Status Messages
Not Requiring
Acknowledgment
The system operates normally after the status is cleared.
When the status is cleared, the LED goes out, the status signal is reset and the
status message is canceled.
Example: Temperature error during the warm-up phase.
Status Messages
Requiring
Acknowledgment
The system operates normally after the status is cleared; however, the operator is
aware of the status.
When the status is cleared, the LED goes out and the status signal is reset. The
status message is only canceled after operator acknowledgment. In this manner,
the operator is aware of the system malfunction.
Example: No new measurement values from the analog/digital converter.
Status Messages
Requiring
Acknowledgment and
Intervention
The system may not operate normally after the status condition is cleared;
therefore, the operator should acknowledge the condition and actively eliminate
the cause of the message.
The LED goes out, the status signal is reset and the status message is only
canceled after the operator acknowledges the status message and eliminates the
cause.
Example: The offset drift between two calibrations exceeds the permissible range.
