17 Technical Information
Use
With normal LOW SPEED operation, the pump will run at about 2/3
of its nominal speed and achieves a base pressure somewhat higher
than the standard specifications. If the gas load becomes higher, the
controller output frequency and voltage decrease automatically, and
the Turbo-V pump is slowed down in proportion to the gas load until
it reaches 4 KRPM.
If the LOW SPEED mode is selected after normal operating condition
is reached, the display shows:
A
while approaching the low speed value.
When the low speed mode is deselected, the pump accelerates to its
rotational speed. During the acceleration, the display shows:
N

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.
