where: XXX = indicates the rotational speed (510 Hz for high speed,
or 555 Hz for low speed).

Operating the Pump

After the starting period, if the system has a vacuum leak or the
pressure in the pump chamber is high (from 1 mbar to atmosphere),
the pump continues to operate indefinitely. If the gas load at the
turbopump inlet flange continues to stay high, the power drawn by
the turbopump increases up to the maximum value.
Then the Turbo-V 2300 pump is slowed down in pro- portion to the
gas load at least until it reaches about 4 or 3 Hz.
As soon as the gas load decreases, the pump will automatically
accelerate to reach normal operation. The pump can be stopped at
any rotational speed and can be restarted at any rotational speed
from either the front panel buttons or the remote connections. The
controller automatically synchronizes the output to the rotational
speed of the pump and then accelerates linearly up to the nominal
speed or within steps if the Soft Start has been selected.

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.
