Upon starting any bike program, if the screen will not
advance, asks if you would like to end workout, RPM
signal is not being detected at the upper console, check
the following:
1. Starting from the console assembly check to make sure
the console data cable is plugged in firmly to the console
and into the lower board and check for
disconnections/cable damage in the pedestal neck.
2. If damage is found and cable has no continuity replace
cable. If cable tests good with a meter proceed to the next
step.
3. Check to make sure there is AC voltage at the lower board
from all three phases from the generator. The white cable
on the generator cable carries the RPM voltage.
4. If there is no AC voltage on the white cable check the
continuity of the cable. If there is no continuity replace the
generator cable. If there is continuity proceed to the next
step.
5. Check the voltage across all three phases of the generator.
If there is not voltage when the generator is moving across
all three phases replace the generator. If there is voltage
across 3 phases replace lower board.
