Troubleshooting the Generator
The generator performs three functions in the AMT. First, by
controlling the amount of electrical load applied to the generator, the
user’s pedaling resistance is controlled. Second, the generator is used
to charge the AMT’s internal battery. Lastly, one of the generators six
phase output windings is monitored to determine when the unit is in use
and when it is idle. This system also determines the stride rate by
determining the operating speed (output frequency) of the monitored
generator winding.
WARNING: Before continuing with this procedure, review the Warning and
Caution statements listed in the Warning and Caution Statements and
General Safety Guidelines Section, Things You Should Know.
