10.TROUBLE SHOOTING FOR E1X E SERIES
FAULT
Alternator does not excite
Low no-load voltage
Correct no-load voltage but too low with load
Correct no-load voltage but too high with load
Unstable voltage
Noisy Functioning
CAUSES
1) Insufficient residual voltage
2) Connection break
3) Broken rotating diode bridge
4) Insufficient speed
5) Windings breakdown
6) Broken voltage regulator
1) Low speed
2) Winding failure
3) Broken rotating diode bridge
4) Broken voltage regulator
5) Wrong setting of voltage regulator
1) Low speed with load
2) Broken voltage regulator
3) Defective winding rotor
4) Load is too high
1) Appliances with capacitors on the load
2) Voltage regulator is broken
3) Wrong connection of phases
1) Rotating mass too small
2) Uneven speed
1) Wrong coupling
2) Short circuit in windings or on load
3) Faulty bearing
