2.3.2 TROUBLESHOOTING – NO RESPONSE FOR MACHINE When Pressing Start
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 "ENTER" key first and
then the key "START".
- When press the key "SPEED + / -", if the data on windows "TIME" & "DISTANCE" change, the
Console is ok. If not, replace the UCB.
c. Verify the motor or running belt spins freely - remove any obstructions from under the running belt
or motor compartment that may cause a block in movement.
d. Check the console cable connection. Also, console cable continuity can be tested with Ohms
on each wire of the cable.
e. Test the drive motor.
1. 30/50 series short test - Disconnect power from the unit. Remove the motor cover. Remove
the red and black motor wires from the MCB. Using a jumper wire (or metal paper clip), make
the connection between the red and black leads of the motor. Without the jumper wire, the running
belt will move freely with little to no resistance. With the jumper wire in place there will be a great
amount of resistance when trying to push the running belt. If there is resistance, the motor is good.
30/50 series battery test - Disconnect power from the unit. Remove the motor cover. Remove the
red and black motor wires from the MCB. Using a DC battery from a cordless drill or other device,
touch the red on the positive lead of the battery and the black to the negative lead. If the motor
runs, the motor is good.
2. 70 series windings test - Disconnect power from the unit. Remove the motor cover. Remove the
motor connection from the MCB. With an Ohm meter test the resistance level between the
motors three phases; pin 1 and pin 2, pin 1 and pin 3, then pin 2 and pin 3. If all three resistance
levels are the same, the motor is good. If one or more are different, replace the motor.
f. If 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 does still not run after to take above actions.
