3.5 Changing Battery
Make sure there is a fully charged battery available to replace the depleted battery.
Disconnect the depleted battery, replace it with the fully charged battery and
conrm it is securely attached.
For information on how to connect and disconnect power sources, see Section 3.2.2.
After a depleted battery is disconnected, the [Low Battery] alarm will resolve, as the
controller will automatically switch to the second power source. If the second power
source is not connected within 20 seconds, the [Power Disconnect] message will
be displayed on the Controller Display and an alarm will sound. The alarm will
automatically clear when the second power source is connected. When the battery
is connected correctly, the Battery Indicator on the controller should light.
WARNING! ALWAYS keep a spare controller and fully charged spare batteries available at all
times in case of an emergency.
