Bogart has a factory installed Fischer Panda generator model P 8.000NE Digital. It is 230V/50Hz, with rated output of 6.8 kW. It is a 2007 model and now has more than 2000 hours on it. My wife and I have owned Bogart for more than 5 years and we've had a few issues over that time, but these have been resolved with some research and some "lucky finds" of mechanics who know something, but not too much, about FPs.
We have now come up against a more difficult issue, the solution for which has eluded the knowledge of the mechanics we have been able to find.
When running the generator at about 50% of load, the engine speed has a tendency to increase, leading to the "engine speed high" alert being activated. This became so common that we took the drastic step of physically limiting the engine speed by moving the nuts on the actuator arm to a point where the engined speed will not exceed 3400rpm. This corresponds to an output of 240V and 53Hz. However, we have made a rod for our back in doing this, as now we can only put about 45% load on the generator. If we seek to load up more that 3.2kW, the output drops below 210V and then we get the "low AC voltage" alert.
Does anyone have any ideas about how we can stop the rpm increasing unnecessarily, but giving us full usage of the output?
Cheers
Tony
