10. Trouble shooting If problems occur after installation of your new Superwind you probably can solve most of them following the trouble shooting list. At all times be aware of electrical and mechanical hazards: WARNING: Do not approach the running rotor. Never try to stop the rotor by hand. WARNING: Be careful when doing work on the electrical system, since most of the lines are live. WARNING: Never short-circuit the batteries. Useful tools for trouble shooting are a multimeter (voltage, current, electrical resistance) and an anemometer (wind speed). 10.1 Wind generator does not start possible source of errors test solution not enough wind measure wind speed wait for more wind. Annotation: start-up wind speed 3,5 m/s (during running-in period slightly higher) stop switch in STOP position switch to RUN wrong connection of the stop switch check stop switch and connection connect correctly debris between generator housing and hub find the debris remove the hub from the generator shaft and eliminate debris generator shaft is stiff turn generator shaft by hand. (for this test the generator must not be short-circuited) repair by authorized service station yaw bearing is stiff, wind generator does not folllow the wind direction move by hand repair by authorized service station 10.2 No power output possible source of errors test solution not enough wind measure wind speed wait for more wind Annotation: Charging possibly will start only with 4,5 to 5,5 m/s. (depending on the battery´s state of charge) current linkage is interrupted check the cabling replace defective line or devices fuse is blown check the fuse replace the fuse carbon brushes are without contact check the carbon brushes and the springs replace the carbon brushes build-in rectifier is defective no increased torque sensible when generator cables have been short-circuited. repair by authorized service station
