4. LED Operation
In short, the Red LED indicates that turbine power is being diverted to the dumpload and the Green LED indicates that the
turbine is spinning and the battery is being charged. The LED operation is detailed in the tables below.
Red LED operation description
State Interpretation
Off Available turbine power directed to battery.
Blinking Available turbine power directed to dumpload for battery regulation.
On Available turbine power directed to dumpload by operator request (via either Diversion
Switch or remote Display).
Green LED operation description
State Interpretation
Off No charge is going to the batteries; either the windspeed is too low or power is being di-
verted (see Red LED).
On The batteries are being charged.
5. Setting Regulation Voltage (without Display)
The battery voltage at which the controller begins regulating the battery (i.e. diverting power to the dumpload) can be ad-
justed by turning a potentiometer on the controller's circuit board. The potentiometer is accessed by removing the Whis-
per Controller electronics cover. When the controller measures a battery voltage above the regulation voltage for more
than approximately one minute, it begins diverting power. If the controller measures a battery voltage below the Release
Voltage for approximately one minute it will stop diverting power and start charging the battery again. When replacing
electronics enclosure cover, do not over-tighten screws. The controller will automatically determine the proper nominal
voltage.
Before you adjust the regulation setpoint understand that turning up the regulation voltage will not increase the
turbine's output voltage or current. This setpoint only adjusts the "shut down" voltage for battery charging. Over-
charging will significantly reduce a battery's life expectancy.
