Error 11: Motion Sensor Defective
Cause:
The motion sensor is reading a consistent value indicative of being unplugged (650-750), or the ground
removed (2100-2900), or power is removed (550-600), or > 3500 (defective) for 10 minutes or greater
while in Opening Screen. Display initiates Dormant from Opening Screen. In Dormant, the GUI shows
a pop-up message indicating the user must touch the screen to begin, and that the motion sensor is
defective.
Use of the motion sensor is disabled outside of Active Mode. Console stores a single Error 11 at the
onset of this condition ONLY. Treadmill is otherwise fully functional.
Service:
• Check the motion sensor cable and connections for damage and replace as needed.
• Read the output value of the motion sensor in Diagnostics to determine the most likely type of failure
(see symptoms above.)
• Test the voltages at the motion sensor connection on the MCC. If OK, replace the motion sensor. If
voltages are inconsistent, replace the MCC and the motion sensor.
