Sea Data Set TH52 2 • 1. 2. 3. 4. 5. English Installation The installation includes 6 major steps: Read the installation and operation manual. Plan where to install the WSI-box, transducers and instruments. Run the cables. Install the WSI-box, transducers and instruments. Learn the functions and calibrate your system. Before you begin drilling ... think about how you can make the installation as neat and simple as your boat will allow. Plan where to position the transducers, Server and instruments.
English 2.1 Sea Data Set TH52 Installing the instrument • Place the adhesive drill template on the desired location for the instrument. Drill the 2 holes using a 5 mm (1/4") drill for the two pin bolts. Use a 63 mm (2½") hole saw to machine the clearance hole for the instrument connection socket. Remove the template.
Sea Data Set TH52 English 2.2 Installing the WSI-box Remove the WSI-box cover from the base plate by removing the screw. Drill the 3 screw holes using a 2.8 mm (0.11") drill. Mount the WSI-box using the 3 mounting screws. Apply silicon paste on the screw terminal. Connect the 8 m Nexus Network cable supplied with cable protectors to the WSI-box on pins 13, 14, 15, and 16. Match the colour codes for each wire.
English 2.3 Sea Data Set TH52 Installing the Log and depth transducers 2.3.1 Correct location of transducer Generally the transducers should be placed as far forward as possible along the waterline length and close to the centreline. It is important that the transducers are always in the water, within the whole speed range of the boat. Please note that the actual waterline length of fast power boats shortens considerably at high speeds.
Sea Data Set TH52 English Sailboats with a fin keel must have the transducer located at least 25 cm but not more than 75 cm in front of the keel. It should be placed no more than 10 cm off the centreline. On sailboats with a pronounced “V” in the hull, such as full-keel yachts, it might be favourable to angle the transducer slightly so that it aims at the bow, rather than directly parallel to the centreline. This will help balanced the passing waterflow measurement from one tack to another.
English Sea Data Set TH52 2.3.2 Installing the through hull fittings 3 Installation Cored fiberglass hull—Follow separate instructions on page 3. Hole Drilling Warning: Always wear safety goggles and a dust mask. 1. Drill a 3 mm or 1/8" pilot hole from inside the hull. If there is a rib, strut or other hull irregularity near the selected mounting location, drill from the outside. 2. Using the appropriate size hole saw, cut the hole from outside the hull.
Sea Data Set TH52 English 4. Remove any excess sealant on the outside of the hull to ensure smooth water flow over the paddlewheel. Warning: The O-rings must be intact and well lubricated to make a watertight seal. 5. After the sealant cures, inspect the O-rings on the valve assembly (replace if necessary) and lubricate them with the silicone lubricant supplied (see Figure 3). 6. Screw the plastic cap nut in place and hand-tighten only. Do not over tighten. 7.
English Sea Data Set TH52 10. Attach one safety ring to one end of the retaining pin. Slide the retaining pin through the valve assembly and paddlewheel insert. Attach the second safety ring to the retaining pin (see Figure 2). Warning: Always attach the safety wire to prevent the insert from backing out in the unlikely event that the cap nut fails or is screwed on incorrectly. 11. Attach the safety wire to one eye in the hull nut. Thread the short emergency plug onto the wire.
Sea Data Set TH52 English 1. Drill a 3mm or 1/8" pilot hole from inside the hull. If there is a rib, strut, or other hull irregularity near the selected mounting location, drill from the outside. (If the hole is drilled in the wrong location, drill a second hole in a better location. Apply masking tape to the outside of the hull over the incorrect hole and fill it with epoxy.) 2. Using the 51mm or 2" hole saw, cut the hole from outside the hull through the outer skin only (see Figure 4). 3.

Sea Data Set TH52 • • 4 English Apply silicon paste to the instrument connection pins at the back of the instrument. Press the jack plug onto the instrument pins. Press the cable in to the cable leads. Mount the connection back cover with the screw. First start 4.1 Initialising the instrument You will be asked to press SET (PrESkey) on the instruments the very first time after installation. This will give the instrument a logical ID number that belongs to your specific Nexus Network.

Sea Data Set TH52 4.3 English Instrument backlight The back light may be switched on at the Sea Data or wind instrument. 1. Press and hold PAGE 2 sec 2. Select backlight level with PLUS 3. Set the light level with SET 5 Function overview of the Sea Data The functions in the Sea Data instrument are divided into 2 pages: SPEED and DEPTH. The selected page is indicated by the LCD mark at top of the display. Each page has 2 types of functions that can be displayed together: 1.
English 6 Sea Data Set TH52 SPEED functions The Sea Data instruments SPEED page is indicated by the LCD marker at top of the display. You can easily combine this main function with any sub function (See 9). SPEED main-function Boat speed through the water Unit available in knots (KT), km/h (Kh) or miles/h (Mh) SPEED sub-functions Both water speed and water temperature is measured from the log transducer. TRIP LOG (TRP) Distance from 0 to 199,99 NM To reset TRIP LOG press CLEAR.
Sea Data Set TH52 English MAXIMUM SPEED (MAX) Maximum speed since power on, or from reset of start timer To reset, press CLEAR DEPTH (unit/DPT) Depth reading can be set to show distance from the water surface or from the keel.
