1) SYMPTOM:
a. The power is on and the console lights up, but the treadmill does not run when keys are pressed.
2) SOLUTION:
a. Check if the console beeps when all keys are pressed. If no, replace the keypads.
b. Enter Engineering Mode (See Section 4.1), and scroll to ENG 1 (Hardware Test).Press the key “ENTER” first and
then the key ”START”.
- When press the key “SPEED + / -“, if the data on windows “TIME” & “DISTANCE” is changed, the console is ok.
If not, replace the PCB.
c. Turn off the power switch, and open the motor upper cover. Remove the red & black wires of motor from the MCB,
and u
se a multi-meter to measure the resistance of drive motor.
If the resistance is bigger than 10
ȍ
, the drive motor is defective. Replace the drive motor.
If the resistance is lower than 10
ȍ
, the drive motor is ok. Then,
- Check the connection of the speed sensor (encoder disk group) at the MCB (Figure A).
- Remove the speed sensor (Figure B) from the motor and clean it, then re-test.
- If the speed sensor is clean and has a good connection but still will not operate, replace the speed sensor.
- Replace the MCB as the last step if machine does still not run after to take above actions.
