26
3-1-9 No AC Output Voltage
Stator main coil defective
Excitation voltage too low
Plugging part contacting poor or loosen
Replace the plugging parts or replace.
3-1-10 No DC Output Voltage
Send to our company repairing station
Wiring connection mistaken or looseness.
Rectification bridge damaged or DC winding
open circuit
Replace the rectification bridge and stator.
3-1-11 Stator Iron Core Overheat
Stator voltage too high operation, and iron core loss
increasing results in iron core overheat.
Adjust generator voltage for keep rated voltage
operation.
Stator winding temperature high, the heat conduct to
the iron core.
If the stator temperature is too high at rated
condition, should lower the generator load.
Rotor exciting current is too big, and rotor winding
temperature too high, heat conduct to the stator iron
core.
Adjust generator load to make the power not out of
the specified valve.
Generator operating with load at low speed, and heat
dispersion condition poor result in iron core heating.
Adjust engine speed for good ventilation.
