Note1) The battery lifetime is the value when no power at all is supplied.
Note2) Note that the lifetime may be shorter than the typical lifetime depending on the use conditions.
Note3) The battery is used for the battery detection circuit even when power is supplied.

Detection of battery error and time for replacement
- Special internal relays R9005 and R9006 will go on if the battery voltage drops. Create a program to
announce errors to the outside as necessary. Two seconds after starting supplying power, the battery
voltage is checked.
- When the system register No.4 "Battery Error Alarm" is enabled, the ERR.LED of the control unit will
flash.
- Although data will be retained for about a week after the detection of battery error without power, the
battery should be replaced as soon as possible.
Note:
- If a week has passed without power after the special internal relays R9005 and R9006 turned on or the
ERR.LED flashed, retained memory data may be lost.
- Regardless of how much time has passed after the detection of battery error, supply power to the
control unit for more than two minutes before replacing the battery.
- Special internal relays R9005 and R9006 will be on when a battery error is detected regardless of the
setting of system register No.4.
