Power Failure

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. The display shows:
