Backup battery abnormality detection and battery replacement time
•
If the battery voltage drops, special internal relays (R9005, R9006) will turn to ON. Develop
an program to send an outside abnormal warning as needed.
•
If the system register No. 4 "Alarm Battery Error" setting is effective, the ERR.LED of the
controller unit controller will flash.
•
After the backup battery error is detected, the data can be maintained for about one week
without power. However, please replace the battery immediately.
•
When special internal relays (R9005, R9006) are ON or the ERR.LED of the
control unit is flashed, if the power outage lasts a week, the data saved in
the memory may be turned to 0.
•
Special internal relays (R9005, R9006) are independent of the system
register setting, if a backup battery error has been detected, it will turn to
ON.
•
Regardless of when the backup battery error was detected, power up the
control unit for more than 2 minutes when replacing the backup battery.
