5.3 Wind Transducer
Location
The sensor must be mounted in the fore-aft direction, with the
sensor forward of the mast so that the wind flow is not affected
by the sails.
Assembly
The transducer is supplied with the vane and cups packed
separately. Fit the vane to the top collar of the transducer body,
so that the shaft in the vane fits into the collar bearings. Once
the vane is in place, screw the counterweight in by hand far
enough to lock the vane into place. Check that the vane rotates
freely - do not over tighten the counterweight using the
supplied Allen key or it may restrict the vane’s movement.
The anemometer cups fit to the base of the
transducer body in a similar way. Once fitted,
they are held in place by a grub screw, which
should be tightened enough to hold the cups
in place without restricting their movement.
Push the cups all the way up before
tightening the screw. Check that the cups
rotate freely afterwards.
To install unit
1. Before installing, apply a coat of silicon
grease to both the plug and socket to
protect the contacts.
2. Apply the self adhesive template supplied
(in the junction box) to the masthead,
pointing fore-aft.
3. Using the template, drill 4 holes 3.7 mm (1/8
in) diameter.
4. Fix the Masthead Bracket to the mast with
the screws supplied.
5. Locate the wand into the Masthead Bracket
as shown (1) and carefully push home. Do
not turn the wand after it is correctly located.
6. When the wand is correctly in position,
screw down the collar until it is HAND tight
(2).
