Manual
pointing to the north is integrated to be set into a correspond-
ing slot of the mounting pipe (if available). Thus the sensor is
safely attached. If needed you can turn in or unscrew the pin
by means of allen key.
To set up the sensor’s north orientation select a land-
mark which is as far as possible up north with regard
to the fi nal position of the wind direction sensor.
The reference point can be selected using a topographical
map (1:25000). The exact position of the reference point is
determined using an amplitude compass that can be adjusted
horizontally on a stand.
Compass declination has to be considered!
To align the sensor ahead (on ships) locate a point outside
the ship in the landscape which is located in the ship ahead
direction respectively in the centre line or in case of the sen-
sor is mounted far away from the middle line a line parallel
to the centre line.
Once the sensor is adjusted, it can be fi xed with the two hex-
agonal screws. Finally the earth screw has to be connected to
the ship’s ground. Acid-free contact grease is recommended
to protect contact surfaces against corrosion.
Follow all safety instructions while setting up the
sensor onto a mast.

Power and Signal
Connection
A 4-pin/ M12 cable socket is required for the electrical con-
nection of the sensor. The shielding of the cable has to be
connected to the protective conductor
To reduce the risk of inductive interference the sen-
sor must be properly grounded (screening on both
sides).
The external connection is via central connector which is
located in housing base. For further details about electrical
connection please see chapter „Connecting diagrams“.
If the sensor is mounted in correct manner and connected
with the right cable (accessory), you can attach the wires to
power supply and signal outputs to data acquisition equip-
ment (computer).
The typical power supply requirements of the EOLOS-IND
sensor are 24 VDC with a maximum current drain of 2.5 A.
The input range is max. 18... 32 VDC
.
The output signal of the sensor corresponds to the RS-485
standard. The signal levels allow transmission via shielded
signal cables up to a maximum length of 1,200 meters or
4,000 feet. The cable lengths depend on the quality of the
cables used.
When the power supply of the sensor is switched on, after
30 seconds (in order to reach operating temperature) the
sensor cyclically starts sending data protocols.
2.7.3
Safety Regulations
Because the wind sensor often is mounted on ex-
posed locations in dangerous heights the installation
personnel has to pay attention to the relevant safety
regulations for such works. During the electrical
installation and termination works the external circuit-
breaker must be switched o

.
It is not permitted to open those housings by unau-
thorised persons!

Maintenance
3.1
Regular Maintenance and
Calibration
The sensor EOLOS-IND is service reduced and designed for
a very long lifetime. Recommended is a regular visual check
regarding dirt of surface caused by the weather and if so, to
clean up.
If reference measurements should be necessary
stringently must be noted that a comparability of the
measured values is given only if the measurements
take place under same conditions. I.e. the reference
equipment must be used very close to the sensor!
The sensor is a measuring instrument and thus apply user
specifi c standards regarding period of recalibration.
Recommendation: 2 years.
We recommend to have the fi lter cap of the humidity-tem-
perature sensor every two years exchanged in our plant.
Depending on the application shorter maintenance cycles
could be necessary.
3.2
Visual Check and Cleaning
The use of the sensor under the respective environmental
conditions requires certain steps. It is thus recommendable
to clean the outside of the housing and shelter within specifi c
intervals. The intervals are dependant on the environmental
conditions and the degree of soiling. We recommend a regular
sight and functional check.

Transports
In case it is necessary to ship or to transport the sensor must
be carefully packed to prevent damages during transport.
