With normal LOW SPEED operation, the pump will run
at the frequency set in ADJUST and achieves a base
pressure somewhat higher
specifications. If the gas load becomes higher, the
controller output frequency and voltage start to
decrease automatically, and the Turbo-V pump is
slowed down in proportion to the gas load until it
reaches about 3 KRPM.
If the LOW SPEED mode is selected after normal
operating condition is reached, the display shows:
A P P R O A C H

while approaching the low speed value.
When the low speed mode is deselected, the pump
starts to accelerate to its rotational speed. During the
acceleration the display shows:

Pump Shutdown
Press the front panel STOP push-button 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:

Remote Control Mode Operation
If remote signals are used to operate the controller, it
must be programmed for remote operation (see
paragraph "Operating parameter selections") and when
ready to start, the display shows:

If the Soft Start has been deselected the display shows:

With or without Soft Start mode selected the
START/STOP and LOW SPEED front panel push-
buttons are inoperative, while the CYCLE NUMBER
and PUMP CURRENT pushbuttons are always active.
Serial Mode Operation
If the serial port option is installed and the controller
has been programmed for serial operation, the
controller may be driven by a computer and when ready
to operate, the display shows:
P U M P R E A D Y

where:

If the Soft Start has been deselected the display shows:

With or without Soft Start mode selected the
START/STOP, LOW SPEED functions are under
computer control, while the CYCLE NUMBER and
PUMP CURRENT front panel pushbuttons
are always active.
