SOURCE: F63 sole treadmill, low speed error when inclined

If the calibration does not pass you may need to check the speed sensoralignment. You must understand the instruction for calibration is under the hood for motor.
1) Remove the motor cover hood by loosening the 4 screws that hold it inplace (you do not need toremove them completely).2) The speed sensor is located on the left side of the frame, right nextto the front roller pulley (thepulley will have a belt around it that also goes to the motor). Thespeed sensor is small and blackwith a wire connected to it.3) Make sure the sensor is as close as possible to the pulley withouttouching it. You will see a magneton the face of the pulley; make sure the sensor is aligned with themagnet. There is a screw thatholds the sensor in place that needs to be loosened to adjust thesensor. Re-tighten the screw whenfinished.

2) if the problem persist you must Test the main motor for open, ground 3) the main control board faulty. See the block diagram that I did as person like you that understand that 90% of functions the main motor controller board has effect.

SOURCE: display shows LS1low speed code

I had all the low speed codes. Company sent new sensor and boards. I still had the same problem. My solution was found when I hopped on treadmill with motor cover off. I discovered the motor was turning properly but the belt drive was slipping. The belt was all oily so I cleaned the belt then tightened the motor tension with the adjustment screw. :)

Treadmill- Epic T60. Immediately starts of at full speed and causes circuit breaker to trip


Hi There,

This problem could be a faulty speed sensor . Especially with optical speed sensors. The other reason could be a faulty LCB ( MCB)

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. The speed control circuit compares the real time speed (speed sensor output) with
the speed that it expects the treadmill to be operating at and acts accordingly to control treadmill
speed or initiate an error code sequence, if necessary. Typically, if a problem exists with the
speed sensor the drive motor will operate (perhaps only briefly) before a speed related error
occurs (errors 20-26).
1. Set the treadmill circuit breaker in the “on” position. Using a DC voltmeter, measure
the voltage between terminal 3 of J2 (green wire) and terminal 4 of J2 (black wire) on
the lower PCA. Slowly, rotate the drive motor flywheel. The voltage should read
approximately 5 Vdc when a flywheel lobe is between the speed sensor “legs” and
approximately 0.25 Vdc when a flywheel lobe is not between the speed sensor “legs”

2. If the voltages in step 1 are correct, go to step 5. If the voltage in step 1 is 0 Vdc or
significantly low when a flywheel lobe is between the speed sensor “legs, continue with step
3.
3. Measure the voltage between terminal 1 of J2 (red wire) and terminal 4 of J2 (black wire) on
the lower PCA. The voltage should read approximately 5 Vdc.

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. There are no good
means of troubleshooting these components other than substituting known good
components. Replace only one component at a time. If the component that you replaced
does not correct the problem, replace the original component. Try substituting the lower
PCA first then the upper PCA, if necessary.
