Fault Check Result Cause Analysis No voltage output after starting Measure phase voltage, usually> 5VAC Loss of magnetization or remanence is too low, need to be magnetized The excitation voltage between F+ and F- should be ＞0.5VDC >0.5VDC • AVR failure • Diode failure • Open circuit of main rotor winding Whether the wiring is wrongly connected, especially the excitation wire and power wire NO • Attempt to magnetize • Try to replace the AVR Low voltage Can the voltage be adjusted YES Check whether the detection input voltage is normal, usually it is caused by the wrong connection of the detection circuit No response AVR failure Check the speed Normal speed • AVR failure • Short circuit of field winding • Diode failure • The main turn the winding is open Speed is too low • Adjust the speed to normal Voltage too high Can the voltage be adjusted No response • Check the AVR's detection input line • AVR failure Unstable voltage Adjust and stabilize potentiometer No effect • Check whether the speed is also unstable • Check whether the speed is low • AVR failure Voltage swing Check whether various protections are operating (corresponding indicator lights) Overexcitation voltage protection Over-excitation current protection Bright Adjust the corresponding protection potentiometer No-load voltage is normal, voltage drops when loaded Check whether the low frequency protection is working (whether the indicator light is on) Bright • Adjust UFRO Check the excitation voltage > 25V • Diode failure • Partial short circuit of main rotor winding • AVR failure
