(12) Integrated value set completion flag (XnC)
When Integrated value set request (YnC) is turned ON, and preset of each integrated value such as electric
energy (consumption), electric energy (regeneration), reactive energy (consumption delay) is completed,
this signal (XnC) turns ON.
When integrated value set request (YnC) is turned OFF, this signal (XnC) turns OFF.
(13) Max./min. values clear completion flag (XnD)
When Max./min. values clear request (YnD) is turned ON and the data of max./min. value (maximum value,
minimum value and their date and time of occurrence) are cleared, this signal (XnD) turns ON.
When Max./min. values clear request (YnD) is turned OFF, this signal (XnD) turns OFF.
(14) Error flag (XnF)
If an outside-set-value error occurs, and if a hardware error occurs, this signal (XnF) turns ON.
The description of the occurred error can be checked with a latest error code (Un\G3000).
If an outside-set-value error occurs, this signal (XnF) is turned OFF by setting a value within the range again.
* For description of error codes, refer to "8.1 List of error codes".
