Connection C – Electrical
The turbopump is connected to the controller through a 6-pin
connector. Pins B, C and D are the 3-phase supply to the motor, pin E
is connected to the pump ground, pins A and F reserved for Agilent.
If the 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 off the power supply.
