Wind Monitoring System

WL-410 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 different
pages. According to the preset values, the receiver can trigger local alarms such as LED
lights and buzzer, or trigger external indication via 4 built-in relays when measured wind
speeds exceeding the thresholds.
A 868 MHz radio frequency module is installed in the receiver. In WL-410XB model, an
additional Bluetooth Low Energy chip is installed 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
WL-410XB for long distance cable transmission.

Power
When the “Lo battery” appears on the display, replace the sensor battery. Take off the
battery cover (on the bottom) by turning it anti clockwise. Pull out the battery holder and
insert new battery (Lithium 3.6 V AA).
Range
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. Inside buildings the range is much shorter. Normally the signal can be received
through two to three walls.
Address
The correspondent sensor address has been preset at the factory. Always set the address
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 sensor battery compart-
ment.
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.

Antenna (SMA connector)
Select the position where the signal reception is strong enough under all conditions.
Connect the enclosed antenna to the SMA connector on the display unit only when the
power supply is switched OFF.
Signal Reception
The reception symbol blinks when the display unit receives a signal from the sensor (every
2 seconds if the reception is good). Signal strength is numerically shown in dB:
-105 dB is approximately the limit where display unit stops receiving
-100 dB and lower means very week signal
-95 ... -90 dB is considered as still acceptable
-85 dB and higher is a good signal
When the sensor doesn't send data (in the OFF state) or when the signal is lost for a more
than 30 seconds, the “No data” notification appears on the display, indicating that the
receiver doesn’t receive data from the sensor (sensor OFF or out of range).
Alarm
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.
By holding-down the upper key for 2 seconds you can switch the sound alarm ON and OFF.
The sound alarm is active each time the display unit is turned ON. In the settings menu, the
sound alarm can be disabled permanently.

Wirings
12 to 24 V DC source
The working voltage of receiver is 12 to 24 V DC. Please plug the power adapter or your own
DC power source to the corresponding jack on the circuit board after opening the front
panel.
Relays for External Alarm Devices
For using relays, connect the connection terminals to external devices.
RELAY 1 : When set value exceed the relay 1 will activate, red light will flash and buzzer will
continuously sound.
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.
RELAY 3 : When wind speed exceeds the value set on pre alarm 1, the relay 3 will activate.
Please see section “Settings” for more details.
RELAY 4 : Set for alerting that the receiver has no data from the sensor or as 2-zone wind
direction alarm.
4-20mA Industrial Outputs (WL410 XB/4-20mA only)
For using 4-20mA outputs, please connect the wind speed and/or wind direction connec-
tion terminals to external devices.
NOTE: Please make sure the polarity is correct otherwise the receiver will be damaged.
