Connection to the Pump

Figure 78
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 bearing temperature sensor (NTC type,
30 KΩ resistance at 25 °C), pins A and G are connected to the body
temperature sensor (NTC type, 10 KΩ resistance at 25 °C) and pin H
is not connected.
If the bearing 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.
