The detection method
The visual check of the abnormalities in a battery can be carried out by blink of
LED3 STATUS in the front panel upper part of a controller.
Moreover, since a battery unusual signal is outputted also from a
general-purpose output, it is detectable also by PLC.

The exchange method
Although the life of a backup battery is about five years, it varies greatly
according to a state of operation and environment of operation. If the
abnormalities in a battery occur, please exchange a backup battery quickly.
Battery exchange is carried out in the state of power supply ON. If batteries
are exchanged in the state of power supply off, a backup circuit will not operate
normally but consumption of a battery will progress remarkably.
