Common Problem and Explain

Special Note

Special Note:
1. Make sure the cooling water is clean, and temperature is no higher than 40℃, with cooling hydraulic pressure more than 0.15Mpa, or it will make the machine vulnerable.
2. Read the instruction carefully before installation, and keep it in good condition after.
3. Keep the inductance in suitable range when designing the induction coil. Please use the induction coil prepared by our company, if you want to make it by yourself please consult our company first, in case improper parameter may affect heating efficiency, or even malfunction.
4. Any connection and installation must be proceeded after power supply and cooling water is shut down, to avoid electric shock.
5. The maintenance must be carried out by trained technician to avoid getting electric shock, and clean the machine regularly.
6. The machine is under the ownership of our company, protected by law, any copy, drawing and dis-assembly without permission that causes malfunction, our company is not under the responsibility to maintain it, and have the right to investigate its behavior. 
7. Malfunction under following circumstances are not included in warranty: water circulation is not installed as required, irregular cleanness of the machine, and unclean water supply.

Inducton Heater Operation Step

For power 05KW to 70KW operation step :
(1) connect water and power supply
(2) Through the water
(3) Connect the three-core cable between the back of main machine to the back of transformer.
(4) Open the air switch on the back of the main machine
(5) Push the red power supply button on the front panel
(6) Push the small green start button on the front panel.
(7) Can not no-load to open the machine (Without workpiece in the coil) and must put the workpiece in the coil to test the machine

For power 80KW to 300KW operation step :
(1) connect water and power supply
(2) Through the water
(3) Connect the three-core cable between the back of main machine to the back of transformer(If machine have not, then no need connect).
(4) Open the air switch on the back of the main machine
(5) Push the red power supply button on the front panel
(6) Push the big green DC power supply button on the bottom of the front panel.
(7) Push the small green start button on the front panel.
(8) Can not no-load to open the machine (Without workpiece in the coil) and must put the workpiece in the coil to test the machine

Induction Heater Installation Step

Installation of electric circuit method:
A: Power supply installation: according to input power, voltage phase, choose suitable wire, knife switch, fuse box. Knife switch of incoming wire, the fuse box must not use air switch in the machine. Keep wire tight. Commonly copper lead wire’s current-carrying is 4A/mm2
   For example; GYH-15A single phase to 8.75mm2  wire(copper), two phase knife switch 35A (4A/ mm2*8.75mm2=35A).     
GYM-80 three phase to 35mm2 wire(copper), three phase knife switch 200A (4A/mm2*35mm2=140A).
B; earth wire installation: according to connection requirement, use upper than 6mm2 copper wire, connect the machine to ground, earth wire can not be mixed with zero line. The ground terminal should nearby dock or use length 1.5 meter above with the factory disposition place wire to meet the ground anchor alone,  and nearby hits the pile earth. The earth resistance should conform to the electrician standard; 
C. inductor installation: the inductor works under massive current, from hundreds amperes to thousands amperes, so it must be fixed tightly. Besides no water leakage, it requires wide contact area. The machine needs to be suitably matched with induction coil to reach best heating effect. When customers need to make induction coils by themselves, please consult our engineers first.
D: remote control and foot switch: remote control matched with machine has the same function with the switch on machine, and both are effective. When using the foot switch, switches on front panel are not available to work. Stepping on foot switch machine begin to work, loosening it machine stops working.
