1. 6 3 Bench Testing Two quick bench tests can verify if your WFD300W B is providing output Test 1 Remove blade assembly from turbine and place in a safe location 2 Spin rotor shaft w ith your fingers while at the same time connecting and disconnecting the positive and negative yaw wires 3 With the yaw wires connected the rotor shaft should become more difficult to rotate and feel lumpy With the yaw wires disconnected it should spin freely Ifthese conditions do not exist you should contact your turbine dealer 6 4 Performance Test Electrical System Your battery bank should be a minimum 400 amp hours for 12 V systems and 200 amp hours for 24V system and 3 6V system If your battery bank is smaller than the recommended size battery voltage could quickly rise while the turbine is charging and cause the internal regulator to prematurely stop charging Measure the voltage at the battery terminals to which the WFD300W B is connected For the factory regulation set point if the voltage for a 12V system reads 14 1V or higher 24V 282 36V 42 3 48V 56 4 then the turbine will sense the battery is charged and stop producing power NOTE THE WFD300W B ELECTRONICS INCLUDING INTERNAL DIODES DO NOT PUT ADDITIONAL BLOCKING DIODES BWTWEEN THE WFD300W B AND THE BATTERIES ANY DIODES BETWEEN THE FD2 5 300 AND THE BATTERIES WILL PREVENT THE TURBINE FROM PROPERLY SENSING THE BATTERIES 7 Maintenance Monthly 7 1 Chec2.
