Solution
• Open the lateral covers
according to the instructions
under "Removing the crank
pedal and lateral covers for
repairs".
• The control board is fixed to
an angle iron at the bottom
of the frame with four Phillips
screws (in front of the tube for
the saddle support). Apply the
following cable connections of
the old board 1:1 to the new
board:
• Lower cable (16)
• Sensor cable (66)
• Power cable (80)
• Connection cable between
controller and eddy current
brake
• Check the plug-in connection
of the computer cables in the
handlebar.
• Check the plug-in connections
on the control board.
• Have the power adapter
checked by an electrician.
• Check the magnet on the v-belt
wheel. The magnet must be
located on one of the spokes
and might have fallen off.
• Check the sensor on the frame:
it must be positioned in such a
way, that the magnet intersects
with the sensor while the v-belt
wheel is turning; the distance
between magnet and sensor
should be as small as possible.
• Check if the sensor cable is
correctly connected to the
control board.
