Pump Shutdown - Aglient Turbo-V 70 PCB Manual De Instrucciones

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 start to decrease
automatically, and the Turbo-V pump is slowed down in proportion
to the gas load until it reaches about 9 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 starts to accelerate
to its rotational speed.
The display shows:
N

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.
An emergency stop signal is provided via a remote contact. This
signal is active in any of the three operation selections: FRONT,
REMOTE, RS 232; when activated, the display will be as shown in the
following figure.
