Note:
In order to conserve battery power when the cycle is not in use, a time out feature is incorporated in
the cycles software. If the cycle is not used (motion not detected by the speed sensor), when in the
program mode, approximately 15 seconds later, the cycle will "power down" The bike will "power up"
again when pedaling is resumed (motion detected by the speed sensor). In order to measure voltages
in the unit it is necessary to keep the unit powered up. This can be accomplished either by pedaling on
the unit or by installing the optional external power adapter.
Attach the anti-static wrist strap to your arm, then connect the ground wire of the wrist strap to
1
the units frame.
2
Pedal on the cycle for a minimum of 5 seconds. The system monitors one of the three phase
generator windings for AC zero cross. The monitoring system notes every time the generator AC
voltage passes through zero volts. By counting the zero cross rate, the system knows how fast the
generator is turning. The system calculates the user RPM from the generator speed. If the system
does not see a zero cross rate, it assumes the bike is not being used and the display will not
illuminate when the bike is pedaled.
3
Disconnect the generator leads from terminals M3 (Red) and M4 (Black) on the lower PCA.
Connect a AC voltmeter to the leads removed from terminals M3 and M4. Pedal the bike at about
60 RPM (1 rotation per second), the voltmeter should read approximately between 80Vac and 120
Vac. If the voltage reading is absent or extremely low, replace the generator. Note: The output
voltage will vary depending on the speed the crankarms are rotating. If you are trying to
measure the voltage and rotate the crankarm at the appropriate RPM may be difficult. It is
recommended that you have someone assist with pedaling the bicycle while taking this
voltage measurement. Use extreme caution by staying clear of the bicycles moving parts
while taking the voltage measurement.
