The voltage cannot be established

The remanence voltage below SVAC

F +, F - reverse

F +, F -, P1, P2, VS1 and VS2 was not completed

The fuse is broken

external AVR Switch is not ON

Engine speed is too low

With external DC electric power transient excitation

Reference 5. Initial voltage induced magnetic field

F + and the F - swap

According to figure 3, 4 way connection

Replace the fuse 16 a 25 ov

The switch is closed (ON)

Engine speed will be dispatched to more than 200 hz

The output voltage is insufficient

Voltage regulator Internal voltage regulation value is too low

Engine speed is too low

In the low frequency protection, voltage selection is not correct

Adjust the knob clockwise, make the voltage value of the rated voltage

Improve the speed

Please refer to the instruction to choose the required voltage and frequency

The output voltage is too high

Voltage regulator internal voltage regulation value is too high

External voltage regulation value is too high, the voltage selection is not correct

Counter clockwise to adjust the knob, the voltage value of the rated voltage

Please refer to the instruction to choose the required voltage

The output voltage instability

Stabilization value and the generator can't cooperate

Magnetic field is voltage resistance is too low or too low

Refer to the "stabilization"

To change or correction field impedance
