Primus Wind Power AIR 40 User Manual
AIR Owner’s Manual 32
The turbine’s internal voltage regulator cannot be completely turned off;
however, by setting the voltage regulation set-point to its highest value
the internal regulator is virtually nullified. If an external charge controller is
utilized, it must be a diversion style regulator which diverts the excess power
to a resistive load.
Do not use a pulse width modulated (PWM) or shunt style controller; the
AIR wind turbine is not designed to work with these types of controllers.
Additionally, most controllers designed to work with solar panels are not
suitable for use with the AIR wind turbine. These controllers “disconnect”
the solar panels – or in this case the AIR - from the battery bank when
the batteries are charged, allowing the turbine to spin free, which is not
recommended.
AIR Wind Turbine Maintenance
Although your AIR has been designed to run for long periods with minimal
maintenance, moving parts must be maintained to ensure maximum
performance and reliability. As part of complying with the conditions of the
Limited Five Year Warranty, please adhere to the below.
CAUTION: Never approach the turbine during operation.
After one month and every six months thereafter:
• Check blades for chips or nicks. Replace blades if damaged. Do not operate
the turbine with chipped or unbalanced blades. This will cause severe wear,
damage and possible failure. Operating the wind turbine with unbalanced
blades may void your warranty. Do not install individual blades as they are
balanced as a set
• Check blade bolts and hub nut for proper tightness. Refer to installation
section for proper specications
• Check nosecone for any cracks and proper t
• Wash o any built-up dirt or debris from the blades for optimal performance.
• Check all electrical connections to make sure they are tight and free from
corrosion
• Check to see that your tower is plumb. A leaning tower will decrease energy
production
Every ve years:
• Replace the blades regardless of their condition. The blades contain UV
inhibitors; however, the sun will eventually erode the composite material.
New blades enhance safety and performance
Every seven years:
• Replace the circuit board. Some components on the PCB require periodic
replacement due to stress from temperature and voltage uctuations seen
under normal operating conditions
• While changing the circuit board, check the condition of the brushes and slip
rings. With the turbine open and the yaw shaft removed, observe the brushes
and slip rings for grooving or other signs of wear
