CHAPTER 5: TROUBLESHOOTING
5.6 NO RESPONSE FOR MACHINE (CONSOLE & MOTOR)
SOLUTION:
A. Check if the console beeps when all keys are pressed. If no, replace the keypads.
B. Enter Engineering Mode, 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 use a multi-meter to measure the resistance of drive motor.
- If the resistance is bigger than 10 Ω, the drive motor is defective. Replace the drive motor.
- If the resistance is lower than 10 Ω, the drive motor is ok. Then,
- Check the connection of the speed sensor (encoder disk group) at the MCB.
- Remove the speed sensor 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 still does not run after taking above actions.
