Operating the turbine in open circuit for a brief period of time will not damage the turbine.
However, operating the turbine in open circuit for a long period of time can cause
excessive wear to the turbine and is NOT recommended. We recommend that during
long periods of operation the turbine should be connected to a battery or the turbine
wires should be shorted. Shorting the turbine will minimize wear to the bearings and
prolong turbine life and is quieter than running open circuit.
b) Normal Operation (Charge)
When the generator is connected to a battery bank in need of a charge, the turbine
blades will spin “normally” with the wind. The turbine will charge the battery bank as
necessary until the battery voltage matches the regulation set point.
NOTE:
When switched from open circuit to charge, you may notice a reduction in RPM
as the generator is now “under load”. If the batteries are fully charged the turbine blades
will slow to a silent spin.
When charging, the
BSG
Controller will turn on the LED.
c) Stall Mode
It will depend on the exact wind speed. When the wind speeds reach 50 mph, RPM
reach 1600 RPM. The turbine will shut off completely and the RPM will slow to almost zero.
4.2 Testing
Three quick bench tests can verify if your
BSG
is working correctly.
Test 1
1. Remove blade assembly from turbine and place in a safe location.
(Do not stand the
blade assembly against a wall.)
2. Spin rotor shaft with your fingers while at the same time connecting and
disconnecting the two 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. If
these conditions do not exist, you should contact your turbine dealer or BSG Wind
power.
Test 2
1. Remove blade assembly from turbine and place in a safe location.
2. Each time the
BSG
is connected to a battery, the LED will blink to
indicate that the controller is running properly.
The test is in order to let any internal voltage drain. If the LED does not blink when the
BSG
is connected to a battery, you should contact your turbine dealer or BSG Wind
power.
