term), the Turbo-V controller will stop the turbopump
and all the interconnected pumps/devices. The Turbo-V
vent valve device, if used, will vent the turbopump only
if the power failure is longer than the preset delay time.
When power is restored, the Turbo-V controller
automatically restarts the interconnected devices and
the turbopump in the proper sequence.
