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.
F. 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 repair or
replace, at its discretion, 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 required
when processing the warranty claim by written. Once LCJ Capteurs has approved the warranty claim,
the sensor must be sent to their workshop address. LCJ Capteurs ensures 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, opened 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.
G. 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 ultrasonic 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
electroacoustic 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 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 0.12 m/s, as well as reliability and excellent linearity up to 40 m/s (144 km/h).
LCJ Capteurs has designed and manufactured ultrasonic wind sensors since 1999. Our range of wind
vane-anemometers covers the needs over many applications. They have proved their robustness and
accuracy in the marine sector.They are now widely used in other fields such as weather stations,
industry, public safety, sports, agriculture and so on.
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 rotating bracket that rotates in steps of 9
degrees. This operation is controlled by computer.
The sensor is first aligned at 0 degrees to the
direction of air flow and then 40 measuring points are
recorded for speed and angle. You can read a typical
test report here on the left. The full document is
available on our website.
3. Installation
A. Delivery control
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.
B. Opening the box
Unpack the parcel in a dry and clean place and check the delivery:
1. CV7SF2 and its receiver.
2. Mounting bracket.
3. Alignment tool
4. User manual
Warning: Unpack the product with care to avoid any damage
C. 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.
Choose a location that is clear of any obstacle to wind. On a boat, it is at the head of mast. Secure the
bracket.

Alignment of the sensor
It is necessary to orientate the sensor towards the
front of the boat. 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 position itself naturally
on the sensor. Align the tool - and the sensor - to the
front. Use the clamping screws in the bracket to lock
the sensor.
Note: The magnetic declination must be taken into account to reference the
measurements to the geographic North.
The maximum radio range is 200 meters. The best performance is obtained with a distance of 50
meters between the wind sensor and the receiver. It should be noted that radio propagation can be
disturbed by building materials (carbon, aluminium, metal, etc.). A minimum distance of 10
centimeters between the sensor tube and a conductive material is recommended. In some specific
cases, there may be reception disturbances. Contact our customer service.
D. Wiring
The CV7SF2 includes a receiver box with a connector to connect to your application and 2 pairs of
wires with connectors for battery connection.
E. Power supply
The PV panel ensures that the CV7SF2 operates independently. The energy is stored in a LiFePO4
battery of 3.2 V –600 mA fitted in a 14500 box.
F. Connection to your application
Supply the receiver and
connect your application (1):
1: GND
2: NMEA -
3: NMEA +
4: +12 V
(1): in case of USB version, skip this step and connect the cable directly to your PC.
4. Starting up
For a correct start, the PV module must supply at the minimum energy comparable to 50 watts per
square meter solar energy.
The battery is disconnected for delivery.

Connected battery
Then, insert the connectors inside
the tube and plug the cap in.
After one minute of initialization and with enough sun exposure, your CV7SF2 is ready to operate.
5. Maintenance
The CV7SF2 does not require specific maintenance. Eventually a periodic cleaning of the photovoltaic
panel may be necessary.
Warning: Do not use alcohol base cleaning products. Use a clean soft cloth, clear water or a
neutral cleaning product.
6. Replacing the battery
Choose a clean and dry location to change the battery.
a) Dismount the CV7SF2.
b) Open the tube.
c) Pull the battery's wires.
d) Disconnect the battery.
e) Spot the North mark on the battery's box.
f) Unscrew the 3 screws of the battery's box:
g) Slide the tube along the cable to access the
battery.
h) Pull the battery out with the wires and
connectors.
i) Insert the wires and connectors of the new
battery until they come out of the other side of
the tube.
j) Put the new battery in place.
k) Slide the tube back to the slot while taking
care of the North mark previously identified.
l) Tighten the 3 screws.
m) Connect the battery.
n) Insert the wires and the connector in the
tube and plug the cap.
o) Mount the CV7SF2 back in place.
Note: When purchasing the battery at LCJ Capteurs, please mention the SKU: DZP_BATT.
Use only original battery with its wires and connectors.
Do not weld the wires directly on the battery.
