Connection C – Electrical
Figure 60
The turbopump is connected to the controller through an 8-pin
connector. Pins B, C and D are the 3-phase supply to the motor, pins
A and F are connected to the temperature sensor (NTC type, 30 KΩ
resistance at 25 °C) and pin E is connected to the pump ground; pins
G and H are not connected.
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 out the power supply.
