ADJUSTING REGULATION VOLTAGE
The AIR turbine enters a regulation mode when the voltage set point is
reached and remains in place until the battery voltage drops to the "cut-in"
voltage (which is slightly lower than voltage set point). The difference be-
tween these two (2) values is called "hysteresis" which prevents the tur-
bine from "bouncing" in and out regulation. The hysteresis is approximate-
ly 0.6V for 12V turbines, 1.2V for 24V turbines, and 2.4V for 48V turbines.
The voltage regulation set point is adjustable using the potentiometer on
the side of the AIR turbine body. To accurately set the regulation voltage,
disconnect the turbine from the batteries and use an adjustable voltage
source (or power supply, if available) and a multi-meter to apply the de-
sired voltage across the positive and negative turbine leads. With the pow-
er supply off, turn the potentiometer screw fully clockwise. Then turn on
the power supply, verify two (2) blinks of the LED on the turbine, and then
turn the potentiometer screw counterclockwise very slowly until the LED
begins blinking. The regulation set point is now fixed to the voltage applied
across the turbine leads. Alternatively, the regulation set point voltage may
be adjusted using a trial and error method. Use the accompanying chart as
a guide to increase or decrease the voltage regulation set point using the
potentiometer screw on the side of AIR turbine body. Monitor the battery
voltage over a period of time and make only small adjustments until the
regulation set point voltage has reached the desired level.
