Connection to the Pump
Figure 32
Also the pump cable is shielded and is equipped with ferrite (see the
following picture).
Figure 33
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 con-nected.
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.
