Troubleshooting:
| 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 |
