NAVIS WS 010-2 User manual

WIRELESS WIND SPEED / DIRECTION SENSOR
MANUAL
Models:
WS 010-2 (wind speed sensor)
WSD 011-2 (wind speed and direction sensor)
PREFACE
Thank you for buying Navis anemometer sensor. This manual provides information for the best performance and safe application of the
WS and WSD wind sensors. This manual does not cover the receiver/display unit, for which the manuals will come separately.
Read this manual carefully before starting the installation of the sensors. Keep this manual after installation for future reference.

BEFORE FIRST USE
For enable sensor power supply remove protective foil from battery contact.
For sensor battery access please look at “BATTERY REPLACEMENT” section.
ASSEMBLY
The sensor is supplied with a battery inserted and is ready for installation.
Before installation insert the cups on sensor. Place the cups on axe and
press the center part with moderate force to end position.
To remove the cups, grab them in the center part and pull from the 1.
axle with moderate force.
WSD sensor - attaching the aluminum rod holder (Figure 3.): 2.
1. Insert the aluminum holder into opening o n sensor (step 1).
2. Insert (step 2) the screw into the assembly hole.
Check and adjust vertical alignment between sensor body 4. 3.
and aluminium tube (step 3).
3. Tighten (step 4) the screw into the assembly hole. Figure 3. WSD sensor assembly
INSTALLATION
WS and WSD sensors to be mounted on 20 mm diameter vertical pool
as shown on Figure 4.
1. 2. 3.
At WSD sensor turn the N mark to Nord.
Calibrating of North is possible also after installation, on display unit.
Mount sensor to highest possible position with unobstructed air flow.
Use self-leveling mounting assembly (optional) if vertical sensor position
can’t be ensured with vertical holder (for example at mobile cranes).
For maximum range there should be a clear and unobstructed line of sight
between the sensor and antenna of display/receiver unit. Figure 4. Sensor installation on vertical pool

OPERATION
Sensors continuously measure and transmit data of wind speed, wind direction and air temperature.
Data packets are transmitted every two second.
Refer to the display/receiver unit manual for instructions on how to connect the sensor and the display unit.
SENSOR ADDRESS
The sensor address is indicated on the label attached to the sensor and on sensor’s PCB.
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 902-928 MHz band. The operating range is up 1300 meters,
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.
Battery replacement:
WS sensor
Unscrew the aluminum bottom part by turning it
anticlockwise (step 1). Pull out the PCB with the
battery (step 2) and insert a new battery (1x 3,6V
AA Lithium battery). Return the PCB with the
battery and screw the bottom part back.
WSD sensor
Take off the cups (step 1). Unscrew the upper head with bearings by turning
it anticlockwise (step 2). Pull out the PCB with the battery (step 3) and insert
a new battery (1x 3,6V AA Lithium battery). Return the PCB with the battery
into the casing (be careful about proper position and orientation of PCB).
Screw the upper head back to its original position and attach back the cups.

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
The receiver/display unit cannot read
the sensor
- check if correct sensor address is set in display unit
- check the sensor battery –replace the battery if needed
- check the operation at a reduced distance to the display/receiver
Interrupting and weak sensor signal
- check for obstructions between sensor and display/receiver unit,
- place the sensor or display/receiver on a different position with better signal reception
- reduce distance to the display/receiver
- change or add an antenna at display/receiver unit
Cups do not turn at low wind speeds
- take off the cups and check bearings
- replace the head with bearings if necessary
