12.1.3 Self Test Failure indication
When a diagnostic self test indicates a failure, an error message is displayed instead of the default metering display, and the Healthy Relay
(K7) is de-energized, no longer indicating proper operation. All other display screens operate normally to permit display of diagnostic information
during troubleshooting. The screen saver is disabled when a warning or failure message is displayed. If more than one warning or failure
condition exists, the FP-5000 scrolls through the multiple error messages. Table 12.1, under the “Display” column, shows all possible displays.
A group of status flags are given in the Status/Control mode that describes the current results of diagnostic self tests. To view these status
flags press the Status/Control button, select “Status” and press enter, select “Self Test Status” and press enter, use the arrow keys to scroll
through the list. Table 12.1, under the “Status Flag” column, lists all of the self test status flags.
