Electronics
If all I/O cables are functioning
properly, LED D indicates speed
sensor is functioning, and err LS or OS
persists problem is in either the upper
electronics board or the motor controller
board. With machine on check LED A
on the controller board. If it is dimly lit
replace upper electronics (000-4430). If
it is not lit at all replace motor controller.

updating.
Size of steps taken
In order for a step to register, the pedals
must pass each other completely. This
ensures that the magnet on the Step
passes the step sensor. Make sure
treadles are not locked in treadmill mode
and that they are moving enough to
register a step.
Step sensor
1. Cycle power off and on
2. Put the machine in calibration mode
(see Calibration procedures, appendix 3)
but do not start the calibration routine.
3. Remove right rear base plastic cover
to allow access to LED board.
CAuTIoN:
Machine is on. Current is
active!!
4. Locate LED C on the motor controller
board. LED may be lit or unlit.
5. Manually manipulate the treadles up
and down and check if LED C is blinking.
6. If LED C is not blinking, then the step
sensor is not supplying a signal. Check
that the step sensor is connected
securely to P2 on the motor controller. If
sensor is connected and LED C still does
not flash replace sensor.
I/o cables
If LED C is flashing when the treadles
are moved but steps are still not being
counted check connections and for signs
of visible damage to any of the three
I/O calbes. If no visible damage check
continuity using a multi-meter. If a multi-
meter is not available replace all three
cables.
