C954, C956 Treadmill Procedure 5.3 - Troubleshooting the Speed Sensor Note: The speed sensor is a hall effect sensor that emits a pulse when a flywheel lobe passes between its transmitter and receiver. The speed control circuit processes the pulse train emitted by the speed sensor. The speed sensor signal is a real time representation of the operating speed of the treadmill.
C954, C956 Treadmill 4. If the voltage is missing or significantly low, disconnect the speed sensor plug from the lower PCA. Measure the voltage between pins 1 & 4 of the J2 plug on the lower PCA. If the voltage is approximately 5 Vdc, replace the speed sensor. If the voltage is missing or significantly low, replace the lower PCA. 5. At this point the speed sensor output is good, but a speed error occurs. There are two potential causes for this condition. They are upper PCA or lower PCA.
C954, C956 Treadmill Procedure 5.4 - Troubleshooting the Fan Sensor manufactured prior to 9/29/2000) (Units Note: The fan sensor function was discontinued on 9/29/2000. This section pertains only to units manufactured prior to 9/29/2000. The fan sensor is an infrared photo-eye sensor that emits a pulse when the infrared beam emitted by its transmitter is reflected back to its receiver. A reflective “target” covers half of the fan hub.
C954, C956 Treadmill 10. If the reading in step 9 was normal, either or both of the blue and brown wires is bad. Check the wires from end to end with an ohmmeter, the reading should be less than 1Ω.
