Using a. 10oM, 10 W resistor, shortcircuit both ends of power supply capacitors C001, C002. C705and C706 in order to discharge the voltage.(2) Before turning on the power switch of the unit,A. Connect the voltage controller to the primary side.B. Connect the AC ampere meter to the primary side or conned the DC voltage meter to the B circuit of the secondaryside.C. Turn the VR of ICQ (VR451, VR452. VR501 and VH502) to minimum (counterclockwise).D. Alter setting the output to zero of the voltage controller, turn on the power switch of the unit.And increase the output of voltage controller gradually.Then, check carefully whether the current value of primary side become more than following value or whether the DCvoltage of secondary side is increasing slowly.E. II the value of current is increasing unusually or the DC voltage is not increasing, lower the output level of voltagecontroller Immediately.The current value of the primary side at no signal.

Turn off the power.2. Determine the cause of the problem and correct it.3. Turn on the power once again.Note:When the protection circuitry functions, the unit will not operateunless the power is first turned off and then on again.I ACCESSORYAC power supply cords For (E), (EG) areas.
