Primus Wind Power AIR 40 User Manual

AIR Owner’s Manual 30
Regulation: When the battery voltage reaches the regulation set point, the
AIR goes into “regulation” and stops charging the battery; blades will slow
dramatically or stop. The turbine remains in regulation until the battery
voltage drops below the regulation set point (cut-in voltage). The blades
then resume spinning in response to the available wind.
In regulation mode, the turbine’s LED blinks approximately once per
second.
Over Speed Protection: In gusty or sustained high winds, over 22 m/s (50
mph), AIR enters overspeed protection where the blades come to a near
stop. The turbine stops the blades for 30 seconds then allows them to
begin spinning. If the wind is still high or gusty, the cycle is repeated until
the wind speeds drop below 22 m/s (50 mph).
Overspeed protection is stressful on the turbine. Primus Wind Power
recommends taking measures to protect the turbine in excessively high
wind situations.
In overspeed protection mode, the turbine’s LED blinks approximately 10
times per second.
AIR Wind Turbine Operation
Operational Summary
AIR converts wind to rotational motion which turns the alternator and
produces electrical power. The voltage is regulated for battery charging
and integrated controls prevent overcharging the batteries, allowing
the turbine to continue charging as battery voltage drops. 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 optimize its power
production capability. The microprocessor continuously adjusts the
loading of the alternator to keep the turbine operating efficiently in most
wind regimes.
The result:
• high power production
• high blade efficiency
• lower blade noise
Operating Modes
Charging:
AIR charges batteries when:
• the batteries state of charge is below the voltage set point and
• sucient wind is available
Charging continues until:
• the batteries are fully charged (at voltage set point) or
• the wind is excessively high
AIR’s integrated controls allow it to generate energy in wind speeds up to
22 m/s (50 mph). Over 22 m/s (50mph), the turbine blades drop in speed
to control heat build-up.
AIR requires a minimum battery voltage to begin charging (example: 10.5
volts on a 12-volt system). Without the minimum voltage, the controller
will behave as if in an open circuit.
In charging mode, the turbine’s LED is continuously illuminated.
AIR 30 Differences: AIR’s integrated controls allow it to generate ener-
gy in wind speeds up to 14 m/s (35 mph). Over 14 m/s (35 mph), the
turbine blades drop in speed to control heat build-up.
AIR 30 Differences: AIR 30 enters overspeed protection in gusty
or sustained winds over 14 m/s (35 mph) and remains there (as
described above) until the wind speeds drop below 14 m/s (35 mph).
