APP

INFO

Fig 2.1 - Analogue Wind Angle Display

The pointer indicates the direction that the wind is coming from, relative to the boat (indicated by the “boat shape” on the fascia). In this example, the wind angle is 45º from the starboard bow. The wind angle can also be displayed digitally see Section 2.5 for further details.

As a standalone instrument, the Analogue Wind instrument can only show the apparent wind angle - this is the direction the wind appears to be coming from, which is distorted by the forward velocity of the boat. In practical terms, this is the correct wind angle to trim to, but true wind angle and speed information can also be displayed if there is input from an IS12 Speed

Log or Combi instrument. See Section 2.4 for more details.

2.2 Apparent Wind Speed

Units indicator

The apparent wind speed is shown on the digital display. This can be shown in knots, metres/sec, miles per hour or Beaufort

(selected in the Units calibration function - see Section 3.1). A digital marker indicates the units selected (Fig 2.2).

4 INSTALLATION

4.1 Instrument Head Installation

All IS12 instrument heads are a standard 110 x 110mm (4.3 x

4.3in) size, and can be mounted either from the front or the rear.

4.1.1 Front Mounting

35mm (1.4in) minimum

Fig 4.2 - Clearance Required

Behind Bulkhead

Fig 4.1 - Front Mounting

Front mounting (Fig 4.1) is the standard method of fitting and is the most straightforward. When mounting the instrument head it is important to ensure that there is adequate clearance behind the bulkhead for the rear of the instrument with the cables inserted - allow at least 35mm (1.4 in) clearance (Fig 4.2).

Additionally, the instrument should not be fitted to a surface that has a curve greater than 1mm ( 1 ⁄

25 in) across the mounting area. If fixing to an uneven surface, care should be taken not to overtighten the screws. When choosing a location, consideration should be given to the water integrity of the gasket seal if the surface is not flat. IS12 is designed to be weatherproof, but the rear of the instrument case with its electrical connections should be protected from moisture as far as possible.

Tools required for installation -

-Drill

- 86mm (3.4in) hole saw

- 2.5mm (0.09in) drill bit

- Countersinking bit

Using the self adhesive template supplied, drill the central aperture for the instrument case using the hole saw, then the four fixing holes as indicated on the template. If the instruments are to be fixed to a GRP bulkhead, the fixing holes should be countersunk after drilling, to stop the screws splitting the gelcoat.

E04054

NOTE

Instruction Manual

The instrument is 110mm (4.33 in) square, but a distance of at least 6mm (0.25 in) should be allowed between adjacent units for the protective instrument cover supplied.

Long term exposure to direct sunlight can damage the liquid crystal display if left unprotected when not in use - always use the instrument cover supplied.

The easiest way to fit the keypad and the bezel to the installed instrument head is to locate the keypad in the keyholes in the bezel and then offer this up to the instrument head, angling the bezel back slightly to prevent the keypad falling out. The bezel should click into place when located correctly (Fig 4.3) -

E04054

Fig 4.3 - Fitting Keypad and Bezel

To remove the bezel, simply lift the top edge of the bezel slightly to disengage the locking clips and pull away from the instrument head (Fig 4.4) -

Fig 4.4 - Removing Bezel

IS12 Wind Speed/Angle

4.1.2 Rear Mounting

When the instrument is rear mounted, only the display can be seen - the main body of the instrument, including the keypad is hidden behind the panel. This is a more elegant method of installation, but does require precise cutting of the apertures into the bulkhead or dashboard. Therefore, it is recommended that

installation is done by a professional marine installer.

The instrument can be fixed to the panel using either the self tapping screws supplied (if the panel is thick enough), or using

2mm studs fixed to the rear of the panel which align with the four fixing holes (Fig 4.5).

Tools required for installation -

- Drill

- 5mm (0.2in) drill bit

- Fretsaw

- A fine toothed file.

To assist in cutting a precise aperture for the display, a self adhesive template is supplied with the unit (Fig 4.6) -

Fig 4.5 - Rear Mounting

NOTE

22

Cut on waste side of template

Fig 4.6 - Cutting Aperture

Fix the template in the correct position and drill four 5mm holes on the waste side of the four corners of the aperture.

Starting from one of these holes, carefully cut along the dotted line around the four edges. To ensure the hole is a good fit, cut slightly inside the line (on the waste side) and then use the file to smooth the edges until the display fits precisely.

Because the keypad is not accessible with this method of mounting, the Remote Control unit (see Section 2.7) will be required to enable control of instrument functions.

4.2 Transducer Installation

4.2.1 Running the Cable

It is easiest to run the transducer cable if the mast is stepped. If this is not possible, all necessary precautions should be taken always use a bosuns chair and ensure all tools are securely attached when working aloft.

Apply the self-adhesive template supplied to the masthead, pointing fore-aft. Drill the fixing and cable exit holes as marked - the masthead bracket incorporates a cable clamp to secure the transducer cable and provide strain relief (Fig 4.7) -

Allow 75mm (3.0”) of cable at the masthead

Fig 4.7 - Drilling Exit Hole for Transducer Cable

The cable can be fed through the side of the mast if this is more convenient.

It is recommended that a grommet is used to avoid damage the cable where it passes through the mast. Allow at least 75mm

(3.0”) of cable at the masthead for the transducer connection.

Cut out blanking piece

For boats with an aluminium mast, a channel is normally provided inside the mast Section for running electrical cables.

This will usually have a tag line, or “mouse” - a length of line running the length of the mast to assist in pulling through cables. If not, the cable will need to be fed down and drawn out the bottom by hand.

For boats with a wooden mast, the cable can be run down the outside of the mast, held in place with galvanised cable clips.

Fig 4.8 - Cable Channel

Exit Points

4.2.2 Fitting the Masthead Bracket

Route the transducer cable in the strain relief channels in the bracket and out the back. If the cable exits through the side of the mast, route the cable in one of the blanked off side channels and out the back (Fig 4.8). Use a sharp knife or scalpel to remove the blanking piece and open up the channel.

BOW

20mm (0.78”)

Attach the masthead bracket with the screws provided. Ensure the bracket is mounted the right way round, so that the wand will be pointing in the correct direction (Fig 4.9). The transducer can be mounted facing aft if required, but it will be necessary to set the transducer orientation to AFT in the calibration menu (see Section 3.2 for more details).

4.2.3 Assembling the Transducer

The vane and cups assemblies are packed separately - fit the vane to the transducer so that the shaft on the top of the transducer fits correctly into the vane (the shaft is keyed so that it will be aligned correctly). Screw the counterweight in just far enough to lock the vane into place (Fig 4.10) -

1) Fit the vane

4.3 Electrical Installation

IS12 instruments are ‘daisy chained’ together, with each instrument linking to the previous one by a single cable carrying power and data (Fig 4.14). The cable plugs into either of the two circular network ports on the rear of the instrument.

Fig 4.14 - IS12 “Daisychain” Cable System

The cable connectors are keyed so that they will always be correctly oriented when inserting the cable into the instrument the flattened edge of the connector should be facing down when inserting (Fig 4.15) -

Network Bus Ports

NOTE

Flattened edge

Fig 4.15 - Rear Connections

The first link in the IS12 system is the power cable, which should be connected to the boat’s 12v DC supply via a 3 Amp breaker or fuse as follows -

Red wire 12v DC

Black wire 0v

Only one power cable is required in an IS12 system, but power must be supplied via an IS12 power cable (with a red connector end), or the system will not function.

E04054

Instruction Manual

A three way joiner (part no. SDJ) is available as a separate accessory (Fig 4.16) -

Fig 4.16 - Three way joiner

The transducer is connected to the instrument using the spare network port on the rear of the instrument (Fig 4.17) -

NOTE

NOTE

Fig 4.17 - Transducer Connections

If the boat is fitted with more than one IS12 instrument, it should be noted that it is not necessary to plug the wind transducer cable directly into the back of the wind instrument - any spare network port can be used.

If the Wind system is being added to an existing IS12 installation with a network terminator fitted, this should be removed as the masthead transducer already has an inbuilt terminator.

4.4 Electronic Interference Suppression

IS12 has been designed to minimise the effects of interference generated by the engine alternator. However, precautions should still be taken by routing the cables away from the engine compartment. Do not run the cables down trunking carrying high current cables. The transducer cable should also be kept separate from the boat’s radio antenna cable if possible.

Engines with spark ignition, also some refrigerators should be fitted with suppressors. Your local agent should be able to advise on this and supply suppression kits where necessary.

5.5 Service & Warranty

Your equipment should seldom need servicing, although it will benefit from an application of silicone or Teflon grease to the contacts each season. The transducer should be removed at the send of the season and stored.

The unit is guaranteed for 2 years from date of retail sale. If it is necessary to have the unit repaired, return it carriage prepaid to the agent in the country of purchase with a copy of the receipted invoice showing the date of purchase. Where possible, return all the components unless you are certain that you have located the source of the fault. If the original box is not available, ensure that it is well cushioned in packing; the rigours of freight handling can be very different from the loads encountered in the marine environment for which the unit is designed.

For Worldwide Warranty details, please refer to the Warranty

Card supplied with this unit.
