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 M8x12 grub 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
drawing). Before the screws of the sensor are tightened, the
sensor is adjusted to north.
Use only the supplied fixing screws and do not
tighten the north screw tightly. Please pay attention
to a firm mounting of the sensor at the mast!
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 firm 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
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 in-hex wrench.
To set up the sensor’s north orientation select a landmark
which is as far as possible up north with regard to the final
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 fixed with the two grup
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.
Note: Follow all safety instructions while setting up
the sensor onto a mast.
The place of installation should not be in the
operation fields 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 field
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 commercially
available tools such as screwdrivers and in-hex wrenches.
2.3
Unpacking the sensor
The sensor is packed in a separate box, carefully protected
against mechanical influences during transport.
Please verify that the following parts and documents are
enclosed:
· 1 sensor u[sonic]WS7 Modbus
· 1 operating manual
Accessories: (depend 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 weather sensor u[sonic]WS6 Modbus has a supply
voltage range of 6...60 VDC. The sensor heating has to be
supplied with 24 VDC.
2.6
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.
