NASA Marine Target Series Guide

The Target wind speed and direction instrument is supplied complete with
display unit, mast headsensor and mounting kit. It is designedto operate
from the vessels 12v battery supply.
PRETEST OF INSTRUMENT
Before mountingcheck that the instrument is complete and undamaged. Plug
the sensor intothe display unit and apply
12 volts. Gently spin the wind cups
and the wind vane and check the operation of the display.
INSTALLINGTHE DISPLAY
Select a convenient positionfor the display on a panelor bulk head.
The site must be flat and the cavity behind the panel must remaindry at all
times. (The cable entry boss is not sealed to allow free passage of air to and
from the unit. This prevents misting of the display.)
The positionsfor the fixing holes can be markedon the panelusingthe drill
template which is an integralpart of the packingcarton. Beforedrillingcheck
that there is sufficient space behindthe panelto routethe cables and to allow
accessto tighten up the wing fixing nuts.
Drillthe five holes and check that the unit fits. It may be wise to connect the
cables beforefinally fixing the unit in position. Connect the black wire to
negativeand the red to positive. It is wise to use a fuse to provide protection
should afault occur. The current consumption
is very small, a 1/4 AMP fuse
is morethan adequate. For display illuminationthe orange lead is also
connectedto positive. This can be connectedthrough a switchwhich controls
illuminationfor other instruments.
A sponge rubber seal is provided which should be fitted into the slot in the
back of the instrument.
Fitthe instrumentinto the paneland tightenthe four wing nutsfinger tight only.

It is importantthat the sponge rubberseal makes good contact with the panel
or water may get behind the unit and enterthe cavity behindthe panel.
It is always good practice to take the cables vertically down from the unit.
INSTALLING THE SENSOR
The sensor is designedfor mast mounting and is suppliedwith 15 metres of
cable. Choosea positionwhere the sensor can receivean unobstructedflow
or air from all directions. The sensor must be substantially horizontal,the
orientationwith respect
to the boat is unimportant. Four mountingblocks
together with four stainlesssteel self tapping screws are supplied
to screw the
sensor
to a metal mast. If the sensor is to be fitted to a wooden mast suitable
screws should be used.
After the sensor is securelyfitted run the cable
to the display unit and plug into
the socket
on the display. Stow any excess cable, do not cut off the plug. If
the cable is
not long enough, a 10 metre extension cable is available.
ADJUSTMENT OF MASTHEADALIGNMENT
If power isapplied to the instrument
wind direction howeverwill not necessarilydisplay the correct angle untilthe
the wind speed will now function. The
alignment procedurehas been completed. With the wind vane pointing
forward along the axis of the boat, turn
off the supply to the unit. Pressthe
vl key and keep depressedwhilst the supply is turned back on. Release
the key and the indicatingarrow will step round the display
to the correct
position. Turn
off the supply and turn back on and the unit will be fully aligned.
READINGTHE DISPLAY
The numbers on the left of the display indicatethe wind speed directly in knots.
The arrow on the right of the display shows the direction of the wind relative
to
the boat's heading. Whenthe wind angle is betweentwo arrows then both
arrowswill indicate. The keys and have nofunction but are
included
to makethe unit compatiblewith any future software developments.
Whenthe unit is not in use replacethe cover over the display
to prevent physical
damage.
