5. Recycling
LCJ Capteurs encourage recycling of all material when possible, following local regulations. You can find more
details about recycling by contacting the local authorities in charge of Environment Protection in your country.
European Union (and European Economic Area) only.
These pictograms indicate that the product cannot be disposed of with waste, according to
the European Directive DEEE (2002/96/CE), the Directive applying to batteries disposal
(2006/66/CE) and local waste regulations following these directives. When a chemical toxicity pictogram is
printed below this one, according to the Directive applying to batteries disposal, it means that Heavy Metals
are present (Hg = mercury, Cd = cadmium, Pb = lead) in the battery at or above the applicable cut-off
concentration specified in the Directive. This product must be given to a disposal centre, i.e. when you
purchase a new similar product, or to a designated collection point for the recycling of waste electrical and
electronic equipment (EEE). Wrong behaviour in disposal can have consequences on the environment and
human health, because of the potentially hazardous substances generally associated to electric and electronic
equipment. Your contribution to a correct disposal of this product will contribute to efficient use of natural
resources.
6. Warranty
Your LCJ CAPTEURS product is warranted against manufacturing defects in materials and workmanship for a
period of 24 months from the date of purchase. LCJ CAPTEURS will at its discretion, repair or replace faulty
products free of charge at their premises. The warranty does not cover the installation labour and shipping
costs of the faulty parts. A proof of purchase can be asked when processing the warranty claim by written.
Once LCJ CAPTEURS approve the warranty claim, the sensor must be sent to their workshop address. LCJ
Capteurs guaranties that each wind sensor is tested and calibrated before despatch.
The warranty does not apply in the following cases:
1. Damage resulting from misuse.
2. Improper installation or inappropriate conditions of operation.
3. If the product has been damaged, open or repaired by an unapproved agent.
4. Damage resulting from lightning, fire or any similar circumstances.
Warranty is void if operation, use, installation and technical service instructions have not been followed and if
a repair has been carried out without prior agreement.
7. Product return
Contact your dealer prior to returning a product to LCJ CAPTEURS. A Return Merchandise Authorisation (RMA)
must be issued and received before sending a product back.
2. Introduction
A conventional Wind-vane Anemometer includes mechanical rotating parts. These parts are subject to wear
and they represent sources of failure of the sensor. Our ultrasonic sensor has been designed to avoid this and
to ensure reliable and stable operation. This Wind-vane-anemometer shows very stable results over a long
term and with no maintenance.
The sound (and ultrasound) is conveyed by the
movement of the fluid in which it crosses. The electro
acoustic transducers (1) communicate between
themselves two by two using ultrasonic signals (2) to
determine, following the orthogonal axes, the wave
transit time differences induced by the air flow (3). The

SONIC-ANEMO-DZP

measurements are combined in an integrated calculation to establish the wind speed and its direction in
relation to a reference axis. The temperature measurements are used for calibration corrections. The sensor’s
design minimises the effect of heel angle (4). The CV7 range of products features lateral transducers delivering
four independent measurements. The validity checks are used to measure head wind vectors for calculations.
This method gives a sensitivity of 0.15 m/s, a 40 m/s (144 km/h) reliability and excellent linearity.*
LCJ Capteurs has designed and manufactured wind sensors since 1999. Our range of wind vanes/anemometers
covers the needs over many applications. They have proved their robustness and accuracy on the marine
sector, and they are now widely used in other fields such as weather stations, industry, security and
agriculture to name a few.
At LCJ Capteurs, each sensor is fully tested before despatch and the test results are saved against the serial
number. The sensor is placed in our wind tunnel on a
bracket that rotates through 9 degree steps. This is
Computer Controlled. The sensor is aligned at 0 degrees
of the air flow and then, 40 measure points are completed
with data saved for speed and angle. You can read a
typical test report here below. The full document is
available on our website.
3. Installation
1. Checking the delivery
Before opening the box, check it carefully to spot any damage that can have occurred in transport. If the
packaging is damaged, fill in a Freight Claim with full description of the problem.
2. Opening the box
Unpack the parcel in a dry and clean place and check the delivery:
1. SONIC-ANEMO-DZP with a 5 m cable.
2. Mounting bracket with 4 nuts.
3. Alignment tool
4. User manual
Warning: Unpack the product with care to avoid any damage
3. Choose the best location
The choice of the appropriate installation location is crucial to get the best measurements. The location must
be free of turbulence and magnetic field resulting from electricity, engines, radio transmitters, radars, etc. For
mobile installations, consider that the sensor measures the apparent wind speed and angle. This has to be
integrated in the data process to calculate the true wind vector.
a) Clearance distance
To avoid measurement errors the sensor must be installed at a distance of at least 10 times the height of the
nearest obstacle.

SONIC-ANEMO-DZP
© LCJ Capteurs 2016 –All rights reserved. Page 4
We recommend installing the sensor at a height of 3 metres in a clear environment and a minimum of 10
metres from nearby objects.
b) Height of mounting
When the sensor is installed on the
top of a building roof, the
installation height must be equal to
the building's length or, if possible,
5 times the building's height.
Install the sensor in the middle of
the roof when possible. It is not
recommended to install a sensor on
a slanted roof. These roofs
generate upwards turbulences that
will affect the sensor.
c) Alignment of the sensor
The sensor must be aligned to North. An alignment tool is supplied for this
purpose. Clip the tool on the tube and slide it so that it snaps into the dedicated
slots. Do not tamper with the slots. The tool must gently find its place.
Slightly loosen the 4 screws that hold the tube. Align the tool - and the sensor - to
North. Tighten the screws.
Note: Magnetic deviation must be considered to reference the
measurements to True North.
d) Mounting methods
The SONIC-ANEMO-DZP comes with a mounting bracket allowing two mounting methods:

On a pole:
Pole diameter: Ø 35 min ; Ø 48 max.
On a vertical surface:
(the sleeper screws are not supplied)
Stop
Max. tightening torque: 1.5 N.m
Ø 6 max
4. Wiring
The SONIC-ANEMO-DZP includes a data cable with a RJ11
connector to connect to the VP2 Interface and 2 pairs of wires
with connectors for the battery connection.
5. Power supply
The PV panel ensures the SONIC-ANEMO-DZP operates independently.
The energy is stored in a LiFePO4 battery of 3.2 V –600 fitted in a 14500 box.
6. Connection to the ISS Davis VP2
Follow the following instructions to connect the SONIC-
ANEMO-DZP to a ISS Davis VP2 :
a)- Open the SIM box, sliding the cover upwards.
b)- Disconnect the Solar Module if it is fitted.

c)- Take out the cap to insert the SONIC-ANEMO-DZP's RJ11.
d)- Connect on the "WIND" socket.
b)- Connect the Solar Module back if required.
f)- Put the cap and the cover back in place.
Note: Refer to your DAVIS VP2 for more information about the Interface Module.
