The 12 volt jumper is also the feedback that tells the Crio when the battery is falling to the point the 24 volt power supply will not keep running. The Crio inhibits all output when the power supply falls below 5.5 volts. The 24 volt supply drops out about 4.5 volts. The Crio inhibit is a safety feature to prevent the robot from running by itself.
