This Wind speed & direction indicator with Alarm receives signal data from Aero plane type wind speed &
direction sensor, and then processes the data using the built-in microprocessor to display various wind
speed and direction information and to output alarms.
The digital screens on the display make it easy to read instantaneous and mean wind speed and wind
direction. (It is necessary to switch between displays of instantaneous or mean wind direction by changing
the setting.)
There are three levels of alarms for wind speed: alarms 1, 2 and 3, each of which can be set for the desired
instantaneous or mean wind speed by using the push-button switches on the front panel.
There is also a wind direction alarm, for which a range of wind direction can be set.
Each alarm signal of Alarm 1, 2 and 3 is output via a relay contact. When an alarm is activated, the alarm
light turns on and the buzzer starts sounding.
In addition, external output by analog and digital output (RS-422) are possible at option.

III-4. About the display modes
There are three types of display mode that are displayed on the front panel.
(1) Monitor mode : Displays the measurement data under the current settings.
(2) Check mode : Displays the current settings such as the alarm setting values.
(3) Setting mode : Displays the current setting values such as alarm setting values for
configuration.
III-5. Operation buttons
There are four push-button switches, MODE, UP ( ), DOWN ( ) and BUZZER [ENT], on the front
panel.
(1) MODE : Used to change the mode being displayed.
(2) UP ( ) : Used to increase the setting value.
(3) DOWN ( ) : Used to decrease the setting value.
(4) BUZZER [ENT] : Used to stop the buzzer sound when the alarm is output.
Also, used to confirm the setting value that has been entered (works like an
Enter key).
(5) Auto return function
: While in the check or setting mode, if no button is pressed for 60 seconds or so,
the unit automatically returns to the monitor mode. If the setting operation is not
completed within 60 seconds, the value is not changed.
III-6. Display mode
III-6-1 Monitor mode
Wind speed data are displayed in the upper and lower 7-segment LEDs.
Wind direction data (wind direction indication) are displayed using the 16-azimuth red LEDs placed
around the LEDs showing the wind speed data. The 16-azimuth LEDs are always dimly lit for ease of
reading and the measured wind direction is indicated by the brightly lit LED.
Upon power-on, the unit enters the monitor mode.
* You must set either "Instantaneous" or "Mean” wind direction by using the buttons on the front panel.

Remarks
(1) Alarm range of wind direction alarm section 1: From start setting value to end setting value
(2) Alarm range of wind direction alarm section 2: From start setting value to end setting value
* Wind direction angle increases clockwise (N: 0°, E: 90°, S: 180°, W: 270°)
* Turn clockwise from the start point to the end point of the setting range and set it as the range.

Start point 10°- end point 360°:Setting range: 10°- 350°
(1) Button operation
①To enter the setting mode, press and hold the UP [ ]and [MODE] buttons together for at least three
seconds. (Press the UP [ ] button first and then the [MODE] button.)
②The first two digits in the upper LED indicate the mode code, while the current setting value is
displayed in the lower LED. (See "Mode code list" in the setting mode.)
③Every time the UP [ ] button is pressed, the number included in the mode code on the upper LED
increases (a1 (A1), a2 (A2), a3 (A3), …).
Every time the DOWN [ ] button is pressed, the number included in the mode code on the upper LED
decreases (b6, b5, b4, b3, …).
The lower LED shows the current setting value that corresponds to the mode code.
④When the mode code corresponding to the setting value to be changed appears, press the BUZZER
[ENT] button.
The setting value on the lower LED starts flashing to indicate that the value can be changed.
Use the UP [ ] or DOWN [ ] button to increase or decrease the numerical value to the desired value.
⑤When the new value is correct, press the BUZZER [ENT] button to confirm. The value stops flashing to
indicate that the setting value has been successfully updated.
The unit returns to the state of (2) above, allowing other settings to be changed.
⑥Pressing the [MODE] button returns to the check mode. Pressing the [MODE] button again while in this
state returns to the monitor mode.
⑦If the unit is left idle for 60 seconds or so (no button is pressed), it automatically returns to the monitor
