Troubleshooting - Mosa GE 4000 LDS/GS Manual De Uso Y Mantenimiento

REV.0-05/04
Problem
The motor does not start up, or starts
up and then stops immediately
The engine does not accelerate
Non constant speed
Other problems or inconveniences
on the engine
Lack of tension to the AC sockets
Lack of tension to the AC sockets
No-load output voltage too low or
too high
No-load voltage OK, too low with
load
Lack of tension to the c.c. terminals
Trouble shooting
1) Lack of fuel in tank
2) Fuel filter clogged
3) Air leaks in fuel system
4) Other causes
1) Air or fuel filter clogged
2) Overload
1) G.F.I. switch in the OFF position
2) Intervention of G.F.I. switch due
to faulty ground current
3) Faulty G.F.I. switch
1) Intervention of circuit breaker
(thermoprotection)
2) Faulty thermoprotection
3) Faulty alternator
1) Incorrect motor speed
2) Faulty alternator
1) Faulty alternator
2) Overload
3) Number of motor rpm too low
1) Thermoprotection intervention
2) Faulty thermoprotection
3) Faulty diode bridge rectifier
4) Faulty alternator winding
Possible cause
Consult the motor Operating Manual.
GE 4000 LDS/GS
Solution
1) Refill the tank
2) Replace
3) Check the feeding circuit
4) Consult the motor Operating
Manual.
1) Clean and/or replace
2) Check the connected loads and
if recessary reduce
1) Position to ON
2) Disconnect load from AC sockets.
Position the G.F.I. switch to ON; if
the switch intervenes once again,
the fault is on board the machine.
Contrarily, the cause of the G.F.I.
switch intervention is due to a
faulty ground current in the load
or connection cable. Find and
remove the fault.
3) Replace
1) Check total power supplied by
generator; if greater than the po-
wer reported on the specification
nameplate, decrease the load
2) Replace
3) Check rotating diode windings,
alternator excitation capacitor.
See specifc alternator manual.
1) Set the motor's no-load speed
2) Check rotating diode windings,
alternator excitation capacitor.
See specifc alternator manual.
1) Replace rotating diodes
2) Check total load and eventually
decrease
3) Check the fuel supply circuit.
See Motor Operating manual.
1) Check the load current and even-
tually decrease it.
2) Replace
3) Replace
4) Replace
