OPERATION
Sensor switches “ON” automatically when the anemometer cups revolve. Wind speed or direction data are continuously measured and
fresh data are transmitted every 2 seconds.
Auto OFF function:
In no wind condition the sensor switches “OFF” 6 hours after the anemometer cups have stopped rotating.
Auto OFF can be disabled by the user.
Refer to the display/receiver unit manual for instructions on how to connect the sensor and the display unit.
FUNCTIONS
Setting of “Auto Off” function:
“Auto OFF” function is enabled by default - the sensor switches OFF 6 hours after the anemometer cups stop revolving.
During sleep mode sensor does not transmit data and battery consumption is close to 0. Cups rotation will switch the anemometer ON
automatically.
If you wish that anemometer never switches off, for example for temperature monitoring without interruption, you can disable this
function. If
“Auto OFF” function is disabled, the sensor will transmits the data continuously, regardless of wind condition. Battery
consumption can be slightly higher in this case.
Please n
ote: If “Auto OFF” function is disabled, remove the battery when
shipping
or storing the sensor.
SETTING PROCEDURE:
Unscrew the aluminum bottom plug (or WS head on WSD sensor) and carefully pull out the PCB from the casing.
Remove the battery for minimum 1 minute.
Insert back the battery. Within 2 seconds from inserting the battery, place the magnet (not included) on the edge of top of PCB
(Figure 5.). After 2 seconds the LED will start blinking. Remove the magnet after first blink to enable
“auto off” or after second blink to
disable
“auto off”. Settings are stored in permanent memory.
Place the magnet Place the magnet
(at WSD sensor) (at WS sensor)
LED blinks

Setting of “Auto Off” function
Checking the selected AUTO OFF status:
Remove the battery for minimum 1 minute. Two seconds after inserting the battery, the LED will blink once or twice. One blink indicates
that
“Auto OFF” is enabled and two blinks indicate that “Auto OFF” is disabled. Ignore the shorter blinks that follow later.
Sensor address:
The sensor address is indicated on the label attached to the sensor, on
sensor’s PCB and on the sensor packaging.
The receiver/display unit should be SET to this sensor address to receive the data from the particular sensor. Please follow the
connection instructions from the selected receiver/display unit manuals.
Operating with multiple display units:
Unlimited number of various types of compatible receiver/display units can read the data simultaneously from a single sensor, whereby
all receiver/display units must be inside the sensor range with properly set selected sensor address.
Range:
The connection between the sensor and the receiving unit works on free 868 MHz band. The operating range is up to 500 meters
(1300 meters at extended range models), assuming the sensor to be mounted at a height of 10 m and that there are no obstacles
between the sensor and the display unit. The range inside buildings is considerably shorter as the signal can be normally received
through two to three walls. The range also depends on the type of receiver/display unit.
STORAGE
When not in use, it is recommended the cups to be removed, both, the cups and the sensor body to be placed into the original
packaging.
Never store the sensor in a lying position with cups mounted. The cups will become deformed.
MAINTENANCE
Cleaning:
Cleaning can be done with a soft tissue or a cloth soaked in mild detergent. Never use aggressive solvents such as acetone. Make
sure to use a proper force when cleaning the cups in order not to deform the cup arms.
Wind vane replacement:
Unscrew the screw on the top of the vane holder by turning it anticlockwise. Pull out the old vane. New vane place into a correct
position and fix it with screw.
