When the full set of equipment can not operate when the air heat exchanger inverter maintenance inspections of the work can not be ignored. Yung economic electromechanical technicians in addition to quickly resolve problems on the factory floor, the Remote Assistance Similarly, their strengths. A common air heat exchanger converter repair failure: 1, machine hiccup: that is faster or slower when the fan, no display. General control panel short circuit, remove the control panel and then power-on, such as hiccups may be thick-film device around bad. 2, the fan weakness, slow speed: the drive circuit breakdown. On telegraph 8888: FECDF21U1 board U8 bad, there is a small crack. With load shutdown at 8888: inverter inductance quantitative difference or the PC9 former Vice edge of insulation is not enough. Run newspaper in 8888: drive optocoupler short circuit. 4, the high-power inverter: the original fault bombing run no output or E019 repair the often bad U9. No output Q2 is also sometimes bad. Small power inverter: the original fault bombing, repair power no output, often bad R13. Repair bombing is to make a habit of measuring R13 whether 10 European, or other parameters. Air heat exchanger inverter inverter repair the generic types of applications it is not only the application of certain equipment, paper, textile, printing machinery, steel strip, film, painting equipment, etc. It is also widely used in the speed range high precision tension control process control field; elevators, cranes, promotion, parking equipment, or three-dimensional garage need high-speed operation, high starting torque and position control, the promotion of control field; engineering machinery, wire drawing machine, extrusion machine, transmission equipment such as the need for high-speed operation, a high starting torque and position control of the machine control area. On top of several knowledge of the the common air heat exchanger inverter maintenance work, the accumulation of experience, or need long-term practice. Yung economic technicians can also be consulted for more resources.
