5.2 Mounting the Wind Direction Transmitter
The Wind Direction Transmitter can be mounted onto a tube of R 1
1/2"
(
¬
48,3 mm), 50 mm long.
The internal diameter of the mounting tube must be at least 40 mm since the transmitter will be
plugged into an electrical system from below. Solder a cable onto the enclosed plug (see chapter
5.4). After electrical connection, set the wind transmitter onto the tube. North marking and bow shall
indicate to the North.
North Alignment
Rotate the case markings (north marking) on the shaft and on the protective cap until they are
aligned. Then select an obvious point in a northerly direction in the surroundings ( a tree, a building
etc.) with the aid of a compass. Take a bearing on this point over the wind vane and the counter
weight of the wind direction transmitter, and when these coincide screw the wind transmitter into
place. (the north marking must indicate to the geographic north). The instrument is fixed on the
shaft by means of the two hexagon head screws.
Alignment of the comb. Wind Direction Transmitter on a Ship
•
The reference point for the wind transmitter is the roll-axis of the ship, whereat “0°” is related
to the
ship bow
.
Rotate the case markings (north marking) on the shaft and on the protective cap until they are
aligned. Take a bearing on ship bow over the wind vane and the counter weight of the wind
direction transmitter, and when these coincide screw the wind transmitter into place. (the north
marking must indicate to the geographic north).
•
When aligning the comb. wind transmitter on other mobile objects (for ex. vehicles, wind
power plants etc.) this procedure can be adopted
5.3 Electrical Mounting
A shielded cable with a diameter of 7..11 mm and a core section of 0,5…0,75 mm² must be
soldered on to the enclosed coupling socket.
The number of required cores, and the PIN assignment is stated in the connection diagram
(chapter 7).
6 Maintenance
If the instrument has been properly mounted, no maintenance is required. Heavy pollution can clog
the slits between the rotating and stationary parts of the instrument. These slits must always be
clean and unclogged.
After years of use, the ball bearings can suffer from wear and tear. This is expressed in a higher
starting torque respectively in the fact that the Wind Direction Transmitter does not start rotating. If
such a defect occurs, we recommend that you return the instrument to the factory for repair.
