The BP4610 starts after memory initialization is
completed.
(
Refer to “9. INITIAL SETTING LIST”.)
These errors may occur when the BP4610 has been
stored for a long time without being powered on.
However, if such errors occur with high frequency,
the characteristics of the backup battery may have
become degraded.
(
Refer to “7.6 Backup Battery”.)
CALIBRATION MEMORY
CHECK
Calibration value memory sum-
check
The BP4610 starts after calibration value memory
initialization has been completed.
In this case, the BP4610 starts up without calibration
values, and therefore the prescribed performance
cannot be obtained. Since there may be defective
parts, contact NF Corporation or an NF Corporation
sales representative.
