NAVIS WINDY B/M User manual

WINDY ANEMOMETER FOR BOATS
MANUAL
Model: WINDY B/M
PREFACE
Thank you for buying Navis Windy anemometer for boats. This manual provides information for the best performance and safe
application of wind sensors.
Read this manual carefully before starting the installation of the sensors. Keep this manual after installation for future reference.
ASSEMBLY
Before mounting of sensor, place the cups on axe and press them with moderate force to their end position. To remove the cups, grab
them in the center part and pull from the axle with moderate force.
Before mounting, place the sensor on sun for a few hours to charge the battery.
Download the app, set correspondent sensor address and check if smartphone receive the data from the sensor.
INSTALLATION
Mount the sensor by 3 self-tapping screws (not enclosed) to horizontal plate. Optional mounting accessories for mounting to vertical
surface is also available.
For better signal reception it is recommended that the sensor is turned in such a way that it is visible from the helmsman's seat.
OPERATING
Sensor switches “ON” automatically when the anemometer cups revolve. Wind speed and direction are continuously measured and
fresh data are transmitted over Bluetooth every second. In no wind condition the sensor switches “OFF” 6 hours after the anemometer
have stopped rotating. Sensor “switched OFF” parameter can be set with application.
With “Windy Marine” app you can read data of current, average and maximum wind speed, wind direction, temperature or view history
graphs.
RANGE
The range is up to 100 meters - at 10 m sensor mounting height and when there is no obstacle between the sensor and the receiver.
Inside the building the range is much smaller. Range also varies with types of smartphones.
SMARTPHONE APPLICATION
Applications “WINDY MARINE” or “WINDY ANEMOMETER” can be downloaded from Google Play and form Apple App Store.
Detailed instructions of application can be viewed on HELP menu.
ANDROID: Application requires device with Android 4.4 or newer with Bluetooth Low Energy (BLE).
APPLE: Application requires device with iOS 11 or newer with Bluetooth Low Energy (BLE).
Please note that application will increase battery consumption of your smartphone because of active Bluetooth communication.
App can’t operate in background so history graphs are available only with display switched ON.
SENSOR ADDRESS
In application setting menu always set the address correspond to the address of the sensor from which you wish to receive data.
Address of the sensor is indicated on the sensor label. With function “Nearby sensors” in settings menu you can scan and select the
sensors in range.

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 inbus screw on vane holder by turning it anticlockwise. Pull out the old vane and insert the new one. Place it into a correct
position and fix it with inbus screw.
Bearings replacement:
If cups or wind vane not turns at low wind speeds, it is time to replace the head with bearings.
PROCEDURE FOR WIND SPEED HEAD WITH BEARINGS (Figure 8):
Remove the cups by pulling them off the axis (step 1). Unscrew the head with bearings by turning it anticlockwise (step 2). Mount back
the replacement head and reattach the cups.
PROCEDURE FOR WIND DIRECTION HEAD WITH BEARINGS (Figure 9):
Unscrew the screw on the top of the vane holder by turning it anticlockwise and pull out the wind vane (step 1). Unscrew the head with
bearings by turning it anticlockwise (step 2). Mount back the replacement head and reattach the wind vane.
Warning: Please make sure the washer to be greased for proper sealing!

TROUBLESHOOTING
Symptom
Action
Application cannot read sensor data
- check if correct sensor address is set in application settings
- check if the sensor is not in sleep mode (turn the cups to wake up the sensor)
- check the sensor operation at a reduced distance to the smartphone
- reset sensor with placing magnet on mark “R” on sensor housing
Interrupting and weak sensor signal
- check for obstructions between sensor and smartphone
- place the sensor or smartphone on a different position with better signal reception
- reduce distance between sensor and smartphone
- change smartphone. Range varies with different types of smartphones
Cups do not turn at low wind speeds
- take off the cups and check bearings
- replace the head with bearings if necessary
