Troubleshooting
If you experience any operational problem with
your treadmill, cycle the power by turning the
circuit breaker off and then back on; this may
eliminate the fault.
Treadmill Data Center
The Data Center is a row of LED lights on the top
of the motor cover that will allow you troubleshoot
common problems on your treadmill. Below are the
functions of the Data Center lights.
INCLINE UP LED — This signal indication is taken
directly from the command relay that engages the
Incline Up motor windings. No indication during a
commanded movement would indicate the Control
Board is not sending the commanded voltage to the
Incline Motor.
INCLINE DOWN LED — Similarly to the Incline Up
LED, this signal indication is taken directly from the
command relay that engages the Incline Down motor
windings. Indication during a commanded movement
would indicate the Control Board is receiving a
command to move but without actual movement the
Incline Motor itself may not be able to respond.
SPEED 1 — The LED fl ashes with every turn of
the front roller, showing the front roller movement
sensor is functioning correctly. Lack of fl ashing,
would indicate a simple cable / sensor or
positioning problem.
SPEED 2 (CONTROL PWM) — The LED’s intensity
is directly related to speed, the faster the treadmill
is commanded to go, the brighter the LED’s output.
For example if no intensity increase were seen
with an increasing speed request display, it would
indicate the Motor Control assembly is not receiving
the speed control signal. This is not the actual motor
drive control signal, but the console generated
Target Speed value.
IN USE — This is a relay control signal that indicates
that the high voltage power has been applied to the
belt drive circuitry. Illumination of this LED indicates
the Motor Control assembly has received the belt
start command and is attempting to apply power to
the switching control circuitry.
