Description
 High lift inverter maintenance
Model: ME320-LN
Fault: no display
Fault analysis: this inverter as Huichuan brand inverter, according to the fault phenomena of the static measurement of inverter module normal power supply circuit, measuring found switch to short circuit, replace the power supply circuit IC and a switch tube after the failure to lift, measure the power supply voltage is normal. The whole link is well tested. The customer is in the rain when the elevator installation roof caused no display fault detection by frequency converter, input module and power supply were burned, repair power supply electricity in the detection of the output waveform of normal measurement. Replacement of the same type of power input rectifier module after the whole test is normal.
