Setting into operation
3.1 Unpacking
When removing the sensor from the original box take care not to damage the cup rotor and the wind vane.
The measuring ele ments must not be used as a handle.
3.2 Choice of the installation site
For representative wind measuring the sensor should not be installed under the lee of large obstacles. The distance
between obstacle and sensor should be at least ten times the height of the obstacle. Furthermore the sensor should
be at least 5 meter higher than the height of the obstacle.
For operation on ships you should select a mounting place with little interferences of obstacles such as masts,
antennas, and chimneys. In most cases the users mount the sensor on a crossarm on the ship’s highest mast.
3.3 Mounting
After inserting the plug connector into the socket at the bottom of the sensor shaft, the sensor is mounted on a fitting
tube with an outer diameter of 50 mm and an inner diameter at least 40 mm. If a traverse is supplied for the sensor
24513-NMEA then the fitting tube is a part of the traverse.
Before the screws of the sensor are tightened, the sensor must be
adjusted to north.
In order to install the wind sensor fast and correct regarding the
north-adjustment 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 corresponding slot of the
mounting pipe. Therefore the mast piece has to be designed with a
corresponding slot as illustrated in the dimensional drawing.
Alternatively the correct north setting can be carried out by
searching a point outside the vessel in the landscape which is
located in the ship ahead direction respectively in the bow-stern
line or a parallel line in case of the sensor is mounted far away from
the middle line. The sensor finally can be fastened by means of the
two hexagonal screws when the selected point in the outer terrain
is in the view-finder (groove) of the sensor which is located on the
top of its housing. Finally the earth screw has to be connected to
the ship‘s ground. An acid-free contact grease is recommended to
protect contact surfaces against corrosion.
Obey all safety instructions while setting up the sensor
onto a mast.
