17 Technical Information
Connection C-Electrical
The turbopump is connected to the controller through an 8-pin
connector and a 6 pin connector.
8-pin connector
Pins B, C and D are the 3-phase supply to the motor, pin E is
connected to the pump ground, pin G and H are not connected, pins
A and F reserved for Agilent.
6 pin connector
Pins A and F are connected to the body temperature sensor, pins B,
D are connected to the purge valve, and pins C, D are connected to
the vent valve; pin E is not connected.
If one temperature sensor is disconnected, the pump will not start.
To prevent damage to the pump when the temperature exceeds
60 °C, the sensor automatically cuts out the power supply.
We recommend that you fit a separate earth (ground) conductor to
the TV 2300 TwisTorr pump. Use a separate insulated green/yellow
conductor, and use a M5 x 10 screw and shake proof washer (fitted to
the earth hole on the pump) to secure the earth conductor to the
pump. The screw must be fixed with a 2 Nm torque. The impedance
between the pump-body and the earth connection point must be
< 0.1 Ω.
