AIR WIND TURBINE OPERATION
OPERATIONAL SUMMARY:
AIR converts wind to rotaonal moon which turns the alternator and pro-
duces electrical power. The voltage is regulated for baery charging and
integrated controls prevent overcharging of the baeries, allowing the
turbine to connue charging unl the baery reaches a full state of charge.
AIR also uses integrated controls to protect the wind turbine from extreme
wind damage.
AIR incorporates a three-phase brushless permanent magnet alternator
and microprocessor controlled electronics to opmize its power produc-
on capability. The microprocessor connuously adjusts the loading of the
alternator to keep the turbine operang eciently in most wind regimes.
The result is high power producon, high blade eciency, and lower blade
noise.
POWER MODE (Charging)
During charging mode, the turbine’s LED is connuously illuminated.
AIR charges baeries when:
• The baery state of charge is above the minimum threshold (e.g. 10.5
volts on a 12 volt system) but below the voltage set point (set at the fac-
tory at 14.1V for 12 volt turbines but eld changeable via the poten-
ometer)
• Sucient wind is available
Charging connues unl:
• The baery voltage set point has been reached (BATTERY REGULATION
FLOAT/STOP)
• The wind is excessively high (OVERSPEED PROTECTION), approximately
16 m/s (35 mph) or greater
• The wind resource decreases such that the wind turbine RPM’s diminish
below 420 (LED will turn o)
OVERSPEED PROTECTION: In gusty or sustained high winds greater
than 16 m/s (35 mph), AIR enters overspeed protecon where the blades
come to a near stop (approximately two revoluons per second). Depend-
ing on the code revision level for your turbine, the turbine stops the blades
(near stop) unl restart is iniated. If the wind is sll high or gusty, the cy-
cle is repeated unl the wind speeds drop below 16 m/s (35 mph). Depend-
ing on your code revision, the LED may blink roughly 3 mes per second or
once every 2 seconds. Contact Primus Wind Power for further LED varia-
ons between AIR turbine models/voltages.
Overspeed protecon is stressful on the turbine. Primus Wind Power rec-
ommends taking measures to protect the turbine in excessively high wind
situaons.
BRAKE MODE: AIR may be placed in brake mode by directly shorng the
turbine posive and negave wires together or by using a stop switch. The
stop switch rst disconnects the turbine from the baery and then shorts
the posive and negave wires. In very strong winds the blades may rotate
slowly even with the switch acvated. If a high wind event is in the forecast
(gusts greater than 23 m/s (50 mph), it is recommended to consider placing
the turbine in brake mode.
AIR 40 Dierences: AIR’s integrated controls allow it to generate energy in
wind speeds up to 16 m/s (35 mph). Over 16 m/s (35 mph), the turbine blades
drop in speed to control heat build-up. Eventually the turbine may shutdown
completely to avoid excessive heat build-up in high wind condions.
AIR 30 Dierences: AIR 30 enters overspeed protecon in gusty or sus-
tained winds over 16 m/s (35 mph) and remains there (as described
above) unl the wind speeds drop below 16 m/s (35 mph).
