Induction Heater Fault Phenomenon & Solution
Fault Phenomenon & Solution
When faults appear, in order to determine it, according to the followings:
1 .Pull off foot switch or other remote control switch .Using the start/stop button in panel; start / stop button just click on then to bounce, not been pressed.
2 If it is time control device with the 'manual / automatic', option on the 'Manual' position;
3 Let current adjusting knob to the minimum position;
The followings are normal situation, not a fault
1. This device being maximum current and load weight, the current will drop. More current decline, with the temperature for workpiece increasing, lighter load, the current will slowly rise.
2. Panel shows the value of the oscillating current of the same equipment as the power is only the size of the representation, different devices will be a slight deviation of the current show.
Fault | Cause | Solution | |
No power supply indication | No input power supply | Check if the input power supply and down-lead are open or not | |
Control fuse breaks off | Replace 1A fuse | ||
Air switch or panel switch breaks down | Replace | ||
Other faults | Contact the manufacturer | ||
No heating after start and the actual working current indicates "0" | Start failure | Adjust electric current small to start again, if fails, contact the manufacturer | |
Start button or Stop button breaks down | Replace button | ||
Heat stops suddenly when start | Induction coil is short circuit | Remove short circuit between two circles of induction coil or between induction coil and workpiece | |
Induction coil and workpiece do not match | Increase the inside diameter of the induction coil or lessen the number of turns | ||
Alarm when working Stop working of the machine | Overpressure indicator lamp lights | Too high of the input voltage | shut down to deal with the voltage of the electric network or adjust the little blue potentiometer on the main board |
Water-lack indicator lamp lights | Too small of the water flow or water pressure | Shut down to solve the water way problems | |
Pressure range increases | Adjust the pressure range | ||
pressure controller breaks down | Replace | ||
Overheat indicator lamp lights | Too high of the cooling water temperature | The cooling water temperature should not be higher 35℃ | |
Pipeline blocked | Rinse the pipeline | ||
Too hot of the transformer and the IGBT | Stop heating but without stopping the water and power supply. Heat with small power when the cool down. | ||
Temperature control switch breaks down | Replace | ||
Overcurrent indicator lamp lights | There is interference signal | Shut down and make sure if the workpiece touches the induction coil and check the water way. Use small power to try. Contact the manufacturer if still fails to work. | |
