• History of protection function
When the protection function has worked, its history is
stored in memory with a backup. Even if no abnormal-
ity is noted while servicing the unit, an abnormality
which has occurred previously can be defined as long
as the backup data has been stored.
The history of the protection function is cleared when
self-diagnostic function is cancelled by selecting PRE-
SET RESERVED (Memory initialized) of main menu
No. 8 or when the backup data is erased.
* To clear the protection history only, use the sub-
menu No. 6 “PROTECT His (PrHist <- RESET) of
main menu No. 20”.
