CHAPTER 5: TROUBLESHOOTING
5.4 NO POWER TO THE CONSOLE
Preliminary Solution:
A. Check circuit breaker, reset if necessary.(Fig-1)
B. Check if the outlet is well. - If no, please try another functional outlet.
C. Check if the power cord connected well.
- If the power cord connected well but console doesn’t turn on, try another one.
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) –see Page10 Fig-1, 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.
