Battery Status Checking
The PIC firmware of ARK-1388V will keep detecting and monitoring the battery volt-
age of the power input when the system is operating. If it detects the battery voltage
level is lower than 11V in a 12V system or 22V in a 24V system, ARK-1388V will be
shut down with 5 seconds delay. Battery status checking can make sure the battery
will not be run down by ARK-1388V. Similarly, in the turn off procedure, the system
will start hard off shutdown if the system doesn't shut down within the time limit spec-
ified as hard off.
