Wind Alarm System

WL-410/XB Wireless Wind Alarm System consists of a wind speed sensor and a receiver. The sensor
measures wind speed and transmits data to the receiver. The 3.5-inch LCD display of receiver shows
readings on the main page and the history graphs are shown in dierent pages. According to the preset
values, the receiver can trigger local alarms such as LED lights and buzzer, or trigger external indication via
3 built-in relays when measured wind speeds exceeding the thresholds.
A 868 MHz radio frequency module is installed in the receiver of model WL-410 and WL-410XB. In mode
WL-410XB, an additional Bluetooth Low Energy chip is installed in the receiver to enable smartphone
communication functionality. WL-410XB sensor output power is stronger (+14 dBm) than WL-410, allowing a
longer transmission distance. An optional 4-20 mA current loop module is available to both WL-410 and
WL-410XB to make long distance cable transmission possible.

Power
When the “Lo battery” appears on the display, replace the sensor battery. Take off the battery cover (on the
bottom) by turning it counterclockwise. Pull out the battery holder and insert new battery (Lithium 3.6 V AA).
Range
The connection between sensor and receiver goes through free 868 MHz band (optionally 908MHz).
Transmission range is up to 500 meters (1300 meters at models XB) - at 10 m sensor mounting height and
when there is no obstacle between the sensor and the display unit. The range is much shorter inside
buildings. Normally the signal can be received through two to three walls.
Address
The correspondent sensor address has been present at the factory. Always set the address to correspond to
the address of the sensor from which the receiver will receive data. Address of the sensor is indicated on the
sensor label and in the interior of the sensor battery compartment.
Sensor unit switches ON automatically when the anemometer cups revolve. It switches OFF 6 hours after
the anemometer cups stop revolving. In ON state, the sensor updates wind speed data every two seconds.

The indication light on the top of the LCD display blinks when the receiver receives signals from the sensor
(every 2 seconds if the reception is good). Signal strength is numerically shown in dB.
When the sensor stop sending data (in OFF state) or the signal is lost for more than 30 seconds, the “No
data” appears on the display, indicating that the receiver doesn’t receive data from the sensor (sensor OFF
or out of range).
The threshold wind speed of Pre Alarm 1, Pre Alarm 2 and Max Alarm can be configured via setting menus.
Please see the section “Settings” for more details.
• Pre Alarm 1 triggers one LED indicator sit beside the LCD screen.
• Pre Alarm 2 triggers two LED indicators sit beside the LCD screen and the yellow LED on the top of LCD
display. It sounds the buzzer interleaved.
• Max Alarm triggers all three LED indicators sit beside the LCD screen and the red LED on the top of LCD
display. It sounds the buzzer continuously.
Receiver

12 to 24 V DC source
Working voltage of receiver is 12 to 24 V DC. Please plug the DC power source to the corresponding jack on
the circuit board after opening the front panel.
Relay 3 When wind speed exceeds the set on pre alarm 1, the relay 3 will activate. Please see section
“Settings” for more details.
Relay 2 When wind speed exceeds the value set on pre alarm 2, the relay 2 will activate and yellow light will
start blinking and buzzer will sound with interruptions. When the sound alarm is activated you can mute it by
pressing upper key for 3 seconds. Please see section “Settings” for more details.
Relay 1 When set value exceeds the relay 1 will activate, red light will flash and buzzer will continuously
sound. When sound alarm is activated you can mute it by pressing upper key for 3 seconds. Please see
section “Settings” for more details.
The relay jacks are by the side of DC power.
NOTE: Please make sure the polarity is correct otherwise the receiver will be damaged.

Scarlet WindPro display consists of 3 pages including: 1) readings of wind speed; 2) alarm settings and 3)
graphs to provide users information for project management.
By pressing HIST key user can navigate to page 2 and 3 to see the wind speed and max. alarm history. To
switch back to the first-page user can long pressing HIST key for 3 seconds or leave the device alone for 1
minute.
The contents of the display are shown above. Note: in both bar graphs, the max alarm value set by user is
always on the 3/4 bar height. One icon not shown in the photo is data packet receiving indicator and it
flashes by the side the signal strength.
