CONDITION/PROBLEM THINGS TO CHECK SOLUTION
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.

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, Pg. 26) 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 for signs of visible
damage and connections 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.
