Main Page (1)
When first connected, the Display begins with the Main Page. The Main Page displays all of the Controller’s
measured parameters, including battery charging status, windspeed, charging voltage, battery charge cur-
rent, and turbine power.
There are four sub-pages associated with this page. From the Main Display the “A” Function button moves
through the Energy and History menu pages. From the Main Display the “B” Function button moves through
the Mode and Regulation menu pages.
Energy Page (2)
Displayed on the Energy page is the accumulated kilowatt-hours and kiloamp-hours since the last reset.
These can be reset from the reset sub-menu. The leftmost numbers are reset at the factory.
From the Energy page the “A” menu button will go to the History page. The “B” menu button will go to the
Energy Reset page.
History Page (3)
Displayed on this page are the average and peak windspeed and turbine power since the last reset. Wind-
speed is only available if the optional anemometer is installed. Both of these readings can be reset via the
reset menu. From the History page the “A” menu button will go to the Main Display page. The “B” menu but-
ton will go to the History Reset page.
Mode Page (4)
This page displays the current charge mode. When “ON” is displayed the batteries are being charged, pro-
vided that adequate windspeed is turning the turbine. This mode allows the turbine to turn all of the time
unless regulating battery voltage or disabled with the Diversion Switch or from this Mode page. When “OFF”
is displayed any power being produced by the turbine is diverted to the dumpload by the controller. The
“OFF” mode will brake the turbine and prevent it from turning in light winds.
The Controller can switch to “OFF” (Stop) mode in any of the following three conditions:
“OFF_REM” indicates turbine power is diverted to the dumpload due to a request from the Remote Display.
“OFF_MAN” indicates turbine power is diverted to the dumpload due to a request from the Diversion Switch
being placed in the “Stop” position.
“OFF_REG” indicates turbine power is diverted to the dumpload due to automatic regulation at the pre-
scribed voltage.
NOTE: The Diversion Switch set to “OFF” (Stop) manually overrides the Remote Display “ON” function.
The mode can be toggled using the “A” menu button. The “B” menu button will go to the Regulation Set
page.
Regulation Set Page (5)
Once the Whisper Controller Display is hooked to a Controller, the Controller no longer looks to its potenti-
ometer for setting the regulation voltage. Instead, the regulation on and off voltages are set digitally at the
Regulation Page. This page displays a menu allowing change to the Regulation On and Regulation Off set
voltages. Selecting “change” using the “A” menu button will bring up a sub-page allowing the Regulation On
voltage to be changed. Pressing the “B” menu button will increase the voltage to a maximum of 17.0v and
will then roll back to 13.0v. Pressing the “A” menu button will go to the Regulation Off voltage sub-page.
Pressing the “B” menu button will again increase the voltage to a maximum of one voltage setting lower than
the Regulation On voltage and will then roll back to 12.0v. Pressing the “A” menu button will return back to
the Regulation Set page. Pressing the “B” menu button from this page will return to the Main Display page.
Clearly the Regulation Off voltage cannot be specified above the Regulation On voltage.
