3. OPERATING PRINCIPLE
3.1 ELECTRONIC COMPONENTS
3.1.1 GENERATOR
It is a 3-phase generator that supplies power to all the electronic components when the rotation
speed is at least 40 rpm.
It provides the RPM signal to the wa sensor board and to the display.
It provides current to the voltage converter.
The statoric resistance between two of the three phases must be approx. 9 Ohm.
3.1.2 VOLTAGE CONVERTER (TRANSFORMER)
The voltage converter receives the high voltage from the generator and transforms it into low volt-
age (5.5 V) to power all the device electronics.
This board does not have any software. Therefore, if it is replaced no software needs to be loaded.
There are two LEDs on the board:
- Yellow: blinking when it receives the RPM signal from the generator.
- Fixed green when 5.5 Volt have been generated.
3.1.3 WATT SENSOR BOARD
The Wa Sensor board receives the information regarding the brake magnetic eld (changes based
on the position of the brake knob); it also receives the speed signal (rpm) from the generator. It uses
this information as well as an algorithm loaded in its memory to calculate the was developed by
the user and transmits this to the console.
The board has the SN of the device stored in its memory and transmits it to the console each time
the device is turned on.
