Pump Shutdown

Press the front panel STOP pushbutton or remove the
remote signal; the power from the turbopump will be
removed and the pump will begin to slow down.

Power Failure

In the event of a power failure (momentary or long
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.
The display shows:
