Enabling and Disabling the Battery
If you are not using a battery in your controller, the controller will sound an alarm. To
eliminate the alarm, you can disable the battery. The default setting is battery enabled.
Note: You should only disable the battery if you are running the controller
with an uninterruptable power supply (UPS), so that you will not lose power
to the controller.
If you disable the battery, the controller will not give any warnings, nor will it disable
the write-back cache.
If you change this setting, you must reboot the controller for the change to take effect.
To change the battery setting:
1
From the System Menu, select Configuration Menu and press Enter.
The Configuration Menu screen displays.
2
Select Option Configuration and press Enter.
The Option Configuration screen displays.
