Wiring and use
1 connected to the supply line of fire
2 Take the power zero line
3 then coil
4 pick coil
5 60A large current Fairchild IGBT half-bridge consisting of main circuit
6 CLC consider wave power structure, effectively suppress harmonic interference power
7 Simple display connection
8 programmable digital display connection
9 AVR microprocessor based digital control system
10 external 12V work lights, work steady, it does not work, shiny
11 Interface load detecting temperature, then the thermistor and a maximum temperature ° C, an accuracy of ± 1 ° C
12 IGBT temperature sensor interface
13 regulating the power potentiometers. PID regulation needs to be done, the open potentiometer connected additionally a two-pin socket, external 0-5V PID control adjusts the power function can be realized
14 RS485 communication(3KW above to have this function
15 fault indicator interface off during normal operation, flashes when a fault occurs is
16 work lights interface steady during normal operation. When not working does not shine
17 Power LED connector, power supply when steady
18 soft-start interface, usually closed to start, stop off, this output terminal connected to the thermostat
19 factory default shorted bad shorted. When the soft-start the interface connected to the thermostat, be sure to unplug the shorting bad
20 or 24V external power supply 12 to start the interface, refer to Chapter III operation, when using this feature, be sure to pay attention to the direction of voltage.


1、 R/S Start the trigger point

2、 LED 12V~24V  (DC)  Working indicator light


Quick Installation Method Product

Power and coil: the soft-start short circuit terminals after starting work,After OPERATION default display shows the input current,Clamp sense input is recommended to check the current input current is rated current range.Press [shortcut] key onceTo enter the operating frequency,Normal display 10-20kHz,Higher than 22kHz,Description coil around a little,We need to increase the coil,Less than 15kHz,Description coil around more,Need to reduce the coil.Press the [Quick] key,At this phase display,03-05 normal display,Above 08 illustrate coil less,Or insulation layer may be relatively thick,Or coil spacing may be relatively large,Need to be adjusted.When heated to a temperature load of normal production,Three parameters need to meet the standards,Machines can only dream job: a, input current: (are considered within the normal range of 85 to 100% of rated); Second, the working frequency: 10-20kHz, preferably about 15kHz; three phase: between 04-03 .

Protection products

If the electromagnetic heater exception occurs, the protection function is activated, the alarm stopped, the display automatically switches to the following error (exception). In case no following display, or other embarrassing questions, please contact the sales dealer or the company.
After protective function is activated, please deal with causes, electromagnetic heater power off and then on again, then start running.
