5.2 Electrical interface
The EGS is connected with the vehicle wiring through a 15 pole male DSUB connector.
Each EGS application gets its own wiring diagram, describing how to connect these 15 wires to the
vehicle's light system, the transmission control valve and to other outputs and inputs.

'C.V.' stands for Control Valve.
5.2.2 Speed sensor mounting
The EGS can support inductive (2 wire), hall-effect (3 wire) and magneto resistive (2 wire) speed
sensors. Speed sensor informs the EGS about the vehicle and the turbine speed.
This information is used to protect the transmission for overspeeding and implementation of various
functions such as automatic lockup, automatic speed sensed shifting, ... etc.
5.2.2.a Inductive sensors
Sensor installation :
Inductive sensors (p/n 4200572, 4200573 & 4200669) generate analogue voltages with
amplitudes ranging from millivolts to several volts (depending on gear speed and sensor
mounting).
The distance from the sensor head to the gear teeth must be smaller than 0.6 mm. This is
accomplished on each transmission in our factory.
