● History of protection function
When the protection function has worked, its history is stored
in memory with a backup. Even if no abnormality is noted while
servicing the unit, an abnormality which has occurred previ-
ously can be defined as long as the backup data has been
stored.
The history of the protection function is cleared when DIAG is
cancelled by selecting PRESET RESERVED (Memory initial-
ized) of DIAG menu No.8 or by selecting Prt His < DEL (Protec-
tion history deletion reserved) of sub-menu 6 of DIAG menu
No.14 and the backup data is erased.
