Generator Failure
10.5.11
Panda 8000-42NE PVMV-N.R01 - Kapitel/Chapter 8: Generator Failure Seite/Page 117
8.12.1.6 Starter motor is turning the engine, but generator fails to start.
8.12.1.7 Motor does not achieves enough speed during starting process.
8.12.1.8 Motor runs irregular
8.12.1.9 Motor speed drops.
Cause
Solution
Fuel inlet solenoid valve not opening.
Check wire connections and circuitry to solenoid valve. (ref. DC wiring
diagram: Relay K2, Fuse)
Fuel pump not working.
Check fuel-filter and pump: clean if necessary.
Lack of fuel.
Check fuel supply.
Glow-plugs not working correctly.
Check glow plugs and heating time.
Too much air in fuel lines.
Test fuel system for leakage. Bleed air from fuel system (refer to section
"Bleeding Air from Fuel System").
Fuel-filter blocked.
Replace fuel filter.
Low compression pressure.
See motor-manual.
Cause
Solution
Starter battery voltage insufficient.
Check battery.
Damaged bearing(s) piston (seized).
Repairs need to be carried out by engine manufacturer-Service. (refer to
motor-manual)
Cooling water in combustion chamber.
1. Turn generator "OFF" at control panel.
2. Remove the glow plug (see engine-manual).
3. Rotate the motor by hand carefully.
4. Check if there is water in the oil and change both oil and filter if neces-
sary.
5. Determine cause for excess water in the combustion chamber. The
excess water can be caused by a defective air vent in the cooling water
system, which should be checked and cleaned, or replaced if faulty.
Cause
Solution
Faulty centrifugal injector governor.
Have the centrifugal governor inspected by a motor manufacturer-Ser-
vice technician.
Too much air in fuel lines.
Bleed air from fuel system.
Cause
Solution
Lack of fuel
Check fuel supply system:
- fuel filter, renew if necessary
- check fuel pump
- check fuel lines (bleed if necessary)
Lack of intake air.
Check air intake paths.
Check and clean air filter (and intake muffler if installed).
Generator overloaded by too many load.
Reduce the electrical load (switch off load).
Generator overloaded by over-energizing.
Check that the proper capacitor type is installed and that they are con-
nected correctly.
Defective generator (windings, bearings, or other).
Generator must be sent to manufacturer for repair of damaged bearings
or winding.
Damaged engine.
Repair of bearing damage, etc., by motor manufacturer-Service.
