Power Input
The power input of the EOLOS reaches its peak in the start-up
period (activation phase). The maximum of the power input
is 2.5 A. In normal operation the average power input is sig-
nifi cantly lower (see table). The power input mainly depends
on the fl ow rate.

Protection
Generally it is not necessary to protect the secondary side
(24 VDC) of the EOLOS. Normally only the primary side has
to be protected. Nevertheless if the supply should be protected
especially we recommend using a micro-fuse 3.15 A - medium
time-lag.

Installation Procedure
(Short Instruction)
The installation of the sensor involves 3 steps:
(1) Mounting the cable at the sensor and if necessary
draw the cable through the mast.
(2) Mounting the sensor at the mast, but before
tightening the screws you must align the sensor to
the north.
(3) Attaching the cable to the power supply and the
signal acquisition system.
2.7
Mounting
The sensor can be installed on a standard pipe with an outer
diameter of 50 mm and an inner diameter of maximum 40 mm.
Before tightening the two 8 mm socket screws and attaching
the sensor you have to draw the cable through the pipe and
align the sensor into driving direction.
For this purpose the housing is marked accordingly (see draw-
ing). Before the screws of the sensor are tightened, the sensor
is adjusted to north. Please pay attention to a fi rm mounting
of the sensor at the mast!
In addition the sensor has a pin for the north direction. You can
put this pin into the nick at the mast (if available). If needed
you can turn in or unscrew the pin by means of allen key.
2.7.1
North Alignment of Wind
Sensor
For wind direction measurements the north mark on the sen-
sor must be aligned with the geographical north direction.
To adjust the wind sensor in a fi rm and correct manner into
the north direction this item is equipped with an integrated
mounting aid. Inside the inner bottom of the sensor a small bolt
The place of installation should not be in the

fi
elds of radar devices (radar scanners
or radar transmitters), generators or antennas. We
recommend a minimum distance of 2 m to these
installations. Furthermore a minimum distance of
5 m to MF-/ HF- and Satcom- (e. g. Inmatsat, VSat)
antennas has to be kept. The maximum electric
fi
eld
intensity may not exceed 10 V/m (tested according to
EMC standard). When indicated a greater distance
should be kept.
To avoid possible measurement errors due to heat sources as
hot or warm fumes, hot surfaces etc. next to the sensor, the
mounting site should be chosen accordingly.
2.2
Tools and Installation Aids
There are no special tools or materials required for the instal-
lation works. All work can be carried out with standard tools
available in a regular workshop.
2.3
Unpacking the Sensor
The sensor is packed in a separate box, carefully protected
against mechanical infl uences during transport.
Please verify that the following parts and documents are
enclosed:
· 1 sensor EOLOS-IND Modbus
· 1 operating manual
Accessories: (depending on order size, in all cases separately
packed)
Connecting cable with plug and core cable ends
2.4
Goods Inspection
Please thoroughly check the delivery with regard to complete-
ness and eventual transport damages. In case of eventual
claims please contact us in writing immediately.
2.5
Power Supply
The sensor requires at the input connector a 24 VDC nominal
power source for operation.
