AIR WIND TURBINE TROUBLE SHOOTING
ON TOWER TROUBLE SHOOTING:
With the turbine on the tower, observe the behavior of the turbine dur-
ing different states of the stop switch. On a moderate to strong wind day
(winds 15 mph or greater):
1.) Place the stop switch in the STOP position (or RED and BLACK wires
disconnected from the battery and crossed), the turbine should spin ap-
proximately 2 revolutions per second in moderate to high winds. If the
turbine spins at a significantly higher rate than that, it is likely an electri-
cal connection is not secure or is corroded.
2.) Place the stop switch in the OPEN position (or wires disconnected
from the battery), the turbine should repeatedly start up and shut down
roughly every 30 seconds. If the turbine does this with the stop switch in
any position, the turbine is not likely electrically connected to the battery
bank.
3.) Place the stop switch in the RUN position (or breaker turned on), the
LED should blink twice (the duration of the blinks is dependent on the
code revision for that turbine). The turbine will begin spinning up with
sufficient wind and the LED should come on solid (and stay on solid) if
RPM are above 450 and current output should begin. If the turbine does
not spin up and the LED is blinking, it could be that the turbine is in
battery regulation (i.e. battery voltage is higher than the potentiometer
set point, in which case the turbine is behaving appropriately).
NOTE: If the turbine spins roughly two revolutions per second in any
position of the stop switch (i.e. no change in behavior between different
positions of the stop switch), the circuit card (or possibly the stator) is
likely compromised.
IMPORTANT:
it is recommended to "Power Cycle" your turbine as a first step in troubleshooting process. Power your turbine OFF (wait 5 min),
then ON, look for two LED blinks. This process will reset the electronic control circuit and verify the turbine is receiving power.

4.) With the turbine spinning and the LED on solid, monitor current output
(or battery voltage) as the wind resource fluctuates. If monitoring battery
voltage, disconnect all loads (if practical) to insure the turbine is charging
the battery. If the turbine shuts down (i.e. blades come to a near stop) at
times you would not expect, note the LED activity during those times. Also
note if the shut-down duration is consistent.
BENCH TESTS:
If the turbine fails the on tower test (s), the next step is the bench tests
below. The bench tests remove the balance of system wiring as a variable.
TEST 1 Stand Alone Test
1.) Remove the blade/hub assembly from the turbine and place in a safe
location. Replace the rotor hub nut on the rotor shaft.
2.) With the Air turbine completely disconnected and removed from the
battery or any other connection, Attempt to quickly spin the rotor shaft
with your fingers while connecting and disconnecting the red and black
wires (turbine must not be connected to batteries). A second person may
be helpful to perform this test.
3.) With the red and black wires connected to each other, the shaft should
be more difficult to turn. With the yaw wires disconnected it should spin
freely. Spinning the shaft quickly makes this difference easier to detect. If
these conditions do not exist, contact your turbine dealer or Primus Wind
Power.
