Gucbir D-300 - Troubleshooting Generator Issues

10. TROUBLESHOOTING
The generator is running even the electric network is o or electric network is on:
The AC Voltages are being read incorrect or the generator frequency is being read incorrect
* The Phase-Phase Voltages are being read incorrect even the Phase-Neutral voltages are right
* The KW and COSQ values are incorrect even the current is being measured correct:
* When the mains voltage is gone, the ignion switch is opening but the engine is not starng and
the oil indicator light is ickering:
The engine is not starng at the rst march, when repeated engine is not cranking, the oil pressure
sensor is ickering:
- The motor body must be stac grounded, check it.
- The mains voltage may digress from the programmed values, measure the phase voltage.
- Check whether the main voltage is being measured right by pressing the MENU buon on the control
panel.
- Upper and lower limit of the mains voltage may be narrow. Enter the program mode and control the
P_004 and P_005. Standard values must be 170 / 270.
- Hysteresis voltage may be too high. If the mains voltage is o, increase the lower limit as well as the
hysteresis voltage and for the upper limit decrease it as well as the hysteresis voltage. Enter the program
mode and checkup the P_021, standard value is 8 volt.
- The motor body must be stac grounded, check it. Connect the negave (-) terminal and neural and
check whether the problem is gone.
- Read error is -/+ 3 volt.
- If you get errors only while the generator is running; there may be fault in the charge alternator or
charge regulator. Demount the connecon of charge alternator and try again.
- If you are experiencing errors only when the mains voltage is on; the accumulator charge recer may
have been damaged. Switch o the recer circuit breaker and try again.
-The Phase Line is incorrect. Put the phase voltages in correct order.
- Current transformers may have been set with incorrect phases or the poles of some current transform-
ers may have been set inversely. Connect the current transformers with the device and measure the KW
and COSQ one by one, when you complete all connect all.
WARNING!!! By pass the exits of the current transformers that you do not use.
Accumulator (-) may have not been connected with the oil pressure entrance of the device.
- The oil pressure nib may have been le void.
- The oil pressure cable may be disjointed.
- The oil pressure sensor may be broken.
- The oil pressure sensor is closing lately; upon request the oil pressure sensor is changed.
- The oil pressure sensor is closing lately. When the engine o, start the engine; upon request the oil
pressure sensor is changed.
