7.4
Troubleshooting Table and Flowchart
7.4.1 Generator output voltage too low
For 50 Hz versions: less than 200 V
7.4.2 Generator voltage too high (more than 240 V - 50 Hz
7.4.3 Generator voltage fluctuates
7.4.4 Generator not able to start electric motor
7.4.5 Diesel motor fails to start
7.4.6 Starter is turning motor, but fails to start
Cause
Solution
Generator is overloaded.
Reduce the electrical load (switch off load)
Motor is not reaching the rated rpm.
Refer to "motor faults" section.
Defective capacitor(s).
Check capacitors and replace if necessary.
Cause
Solution
Over-energizing due to wrong capacitors.
Check capacitors type and replace if necessary.
Measurering voltage on the VCS circuit board is missing.
Check VCS System, check cable connections.
Cause
Solution
1. Disturbances on the electrical system/user side.
2. Motor disturbances.
1. Check if electrical load is fluctuating.
2. Refer to section: "Motor runs irregular".
Cause
Solution
If the generator is unable to supply enough power to start an electric mo-
tor 1-phase, it is usually because the motor draws too much current du-
ring starting process.
Check the motor's current draw required for starting (switch to 3-phase,
if possible). This could be remedied by providing stronger capacitors or
installing an optional "Easy Start Booster Set" (see Appendix).
Enquire at your nearest Panda dealer or directly at the manufacturer.
Cause
Solution
Starter battery switched "OFF".
Check position of battery switch and switch "ON" (if installed).
Starter battery voltage insufficient (battery too weak).
Inspect battery terminals and cables for a good electrical connection (In-
spect against corrosion, tattered wires, etc.).
Starting current disrupted.
During the normal starting process, the battery voltage drops to 11V with
a fully charged battery. If the voltage does not drop during starting, the
electrical connection is faulty. If the battery voltage drops lower than 11V,
then the battery has been discharged.
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.
