Hydraulic circuit oil pressure sensor
It is installed directly on the hydraulic group.
It is installed directly on the hydraulic group. It consists of a capacitive sensitive element that generates a signal processed by a specific custom circuit inside the metal casing. It supplies the control unit CFC 208F with a voltage proportional to the pressure read, with reference to the supply voltage of the sensor. The supply voltage from CFC 208F is 5+/-0.5V with a draw of approx. 10 mA. The maximum pressure value read is approx. 80 bar.
Actuators position sensor
The sensors that send the position of the gear selection, gear engagement and clutch control actuators to the Selespeed control unit are single ramp potentiometers installed directly on the electro-hydraulic group. They are powered with 5V+/-0.5V by the control unit CFC 208F. Maximum resistance between pins A-B is 1200 +/- 20Ohmat 20°C.
The three sensors, of the same type, installed on the electro-hydraulic group are:
- Gear selection position sensor
- Gear engagement position sensor
- Clutch position sensor
Clutch disk speed sensor (gearbox primary)
This is installed on the gearbox inlet, directly on the gear box. It is an electromagnetic sensor and sends a sinusoidal signal to the control unit CFC 208F that has a frequency in proportion to the speed of a pinion mounted on the gearbox primary shaft. The winding resistance is 1200 Ohm +/- 10% at 20°C. The air gap ranges between 0.2-1 mm.
Switch on brake pedal
Installed on the brake pedal unit.
When the pedal is released it does not send any signal (NC) to the control unit CFC 208F. When the brake pedal is pressed the BRAKE lights switch on and the switch sends the car braked signal (12V) to control unit CFC 208F.
Door open switch
This reads the information (ON-OFF) regarding the state of the driver side door, sending an earth signal to the control unit CFC 208F when the door is open.
