Further Solution:
A. Check if the MCB has power. There is a green LED in red area should flash
.
B. If the MCB does not have power, check the connection of the power wiring from the power receptacle
to the MCB. Use a multi-meter to measure CN1 (AC1 & AC2), AC vol age shall be same
as local’s standard
voltage (110V/120V)
- If AC voltage value is standard, replace the MCB as it shall be defective.
C. If the MCB does have power, check the connection of the console cable wire at the MCB and UCB.
-Remove the console cable CN4 from MCB (section 5.2), and use a multi-meter to measure the DC voltage
between the “GND pin” (Pin 8) and the” + 12V Pin” (Pin1). DC output is normally around DC 12V. If no
output, replace the MCB.
- If output is around DC 12V, check the console cable. If it is defective, replace the console cable.
- If the console cable connections are all good, replace the UCB.
No Function For Safety Key
SOLUTION:
A. Check if the safety key is totally inserted into the console.
- If not, remove and insert again.
B. Check if the safety key is oxidized or its condition does not affect its function.
- If yes, try cleaning it or replace it.
C. If the safety key is functional, check the safety key sensor wires in console.
- Suggest to re-connect the wires or to change new wires.
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.
