1. When the power switch is turned on, the digital display on the control box does not light up. Please check the power connection and all fuses. If the fuse is damaged, please replace it with a new one according to the amperage marked next to the fuse holder.
2. If the power switch is turned on, the digital display is on, the green light for high voltage display is off, and high voltage cannot be applied.
(1) The fault display returns to zero; the light is on and there is no return to zero, please turn the high-voltage output adjustment knob and fine-tuning knob counterclockwise to return to the zero position to return to zero; the light is off, and high voltage can be added.
(2) Fault display other; there are two phenomena when the light is on: grounding protection; disconnection protection.
a. It is possible that the ground wire is not connected well, or the ground wire is not reliably grounded. Please connect a reliable ground wire, turn off the power, and restart.
b. It may be that the cable connecting the control box and the high-voltage tower is not connected properly. Please turn off the power and restart after connecting the cable. Or this fault will occur when the welding heads at both ends of the cable are disconnected. Please weld the welding heads at both ends of the cable, turn off the power supply, and restart.
c. It is possible that one of the wires in the control box is disconnected and disconnected. Please re-solder, turn off the power supply, and restart.
3. The high-frequency DC high-voltage generator is all normal, but it is protected in the process of not rising to the rated output voltage.
(1) The fault shows overcurrent; the light is on
a. The sample is short-circuited, or the leakage current is too large.
b. When the load is large capacitance, the boost is too fast, turn off the power supply, restart, and slow down the boost speed.
(2) The fault shows overvoltage; the light is on and the overvoltage protection setting knob is not placed at the maximum point, please turn it clockwise to the maximum point, turn off the power, and restart.
4. When a short circuit occurs under the high voltage of the test product, due to the large short-circuit current, it is possible to light up all the fault indicators. This is normal. Please remove the test product failure and restart.
5. After the failure of the test product is eliminated, the failure indicator is still on and high voltage cannot be applied. Power switch and fault protection reset switch, please turn off the power and restart to boost the voltage.
6. If the high-frequency DC high-voltage generator finds that the voltmeter's number fluctuates too much, please check whether the 7-pin shield joints of the aviation plugs at both ends of the connecting cable are disconnected. If they are disconnected, please solder them.
