[. . . ] Mount the GyroPlus 2 unit below deck, in a dry location that is: · · · · · · vertical (see below) protected from excessive vibration and excessive temperatures: engine room mounting is not recommended shielded from physical damage accessible for installation and servicing at least 230 mm (9 in) from any compass (including the fluxgate compass in the Smart Heading System) at least 500 mm (20 in) from any radio receiving equipment 2 Installation Orientation As the GyroPlus 2 unit measures the boat's rate of turn, it is important to mount it on a vertical surface (as shown). If necessary, make up a suitable wedge-shaped packing piece to provide a vertical surface. Make sure you mount the unit the correct way up (as indicated on the mounting label) ­ with the power inputs at the bottom left. CAUTION: For the GyroPlus 2 unit to work accurately, you must mount it within +/- 10º of the vertical. For optimum performance, mount the GyroPlus 2 unit so it is as close as possible to vertical.

Remove the outer cover (as shown below). b 2 Installation a D5918-2 2. Temporarily hold the GyroPlus 2 unit in the required position so you can mark the centers of the two fixing holes. Use a 3 mm (1/8 in) drill bit to make two pilot holes. Screw one of the self-tapping screws provided (No 8 x 1 in) into each hole, so each screw-head is at least 15 mm from the surface. Place the fixing holes over the screw heads, then move the GyroPlus 2 unit down so the screw heads are at the top of the keyhole slots. a b b a D5919-1 6. Tighten the screws to secure the GyroPlus 2 unit. Note: Replace the outer cover after you have connected all cables. Chapter 2: Installation 11 GyroPlus 2 unit - power supply As described at the start of this Chapter, you can provide power to the GyroPlus 2 unit either: · · via SeaTalk (12 V) or direct from your boat's distribution panel (12 V or 24 V): using suitable cable protected with a 3 A in-line fuse or equivalent circuit breaker Note: If you connect power to both the SeaTalk terminals and the POWER terminals, the GyroPlus 2 unit will power up when either or both of these is switched on. Power from SeaTalk 2 Installation Red Screen Yellow Plug into SeaTalk instrument or SeaTalk junction box D5951-1 Note: Secure the SeaTalk cable to the loops on the GyroPlus 2 unit with one of the supplied cable ties. Power from distribution panel 3 A fuse or equivalent circuit breaker 12 V or 24 V power supply D5929-1 Note: Secure the power cabling to the loops on the GyroPlus 2 unit with one of the supplied cable ties. 12 Pathfinder Smart Heading System - Owner's Handbook 2. 3 Installing the fluxgate compass Fluxgate compass - description and dimensions The fluxgate compass contains a self-levelling mechanism. This enables the compass to provide accurate readings with pitch and roll movements up to +/- 35°. 76 mm (3 in) 76 mm (3 in) 2 Installation D5381-1 Figure 2-1: Fluxgate compass dimensions Note: The rattle that the fluxgate compass makes when shaken is normal. It is caused by the pendulum weight hitting a buffer inside of the case. Select the location The compass is primarily designed for mounting below deck on a vertical bulkhead. Note: On steel boats the Fluxgate Compass should be mounted above deck (see page 13). Standard location To achieve the best performance from the compass, mount it: · · · · as near as possible to the boat's pitch and roll center to minimize compass disturbance (as shown in the shaded areas in Figure 2-2) at least 0. 8 m (2 ft 6 in) away from the boat's steering compass to prevent deviation of either compass away from the front third of the boat (otherwise shock motion will affect compass performance) away from potential sources of magnetic interference, such as: motors, drive units, loudspeakers, alternators/starters, electric cables, large ferrous objects (such as engines, ballast, keel, gas bottles and tool boxes) Chapter 2: Installation 13 Note: Because the compass is electronically aligned after installation (see Chapter 3: Calibration), you can mount it so it faces in any direction. 0. 3L to 0. 5L L 2 Installation 0. 3L to 0. 5L L D5382-1 Figure 2-2: Compass - recommended location for non-steel hulls Finding the most suitable location To identify the best compass location on your boat, start at the pitch and roll center then move the compass up and/or aft until you find a location with minimal magnetic disturbance. To check if the intended mounting location is free from magnetic influence: 1. Temporarily fix a simple handheld compass at the intended location. Turn the boat through 360°, watching for any differences between the hand bearing compass and the boat's main steering compass. The site is suitable for the fluxgate compass if the differences are less than 10° on all headings. Location on steel-hulled boats On steel-hulled boats you must mount the compass at least 1 m (3 ft) above the main deck or wheelhouse. If mounted below deck, the compass will not work correctly as the hull shields the Earth's magnetic field. 14 Pathfinder Smart Heading System - Owner's Handbook The following diagram shows recommended mounting positions for steel-hulled boats. [. . . ] Note: If you need to calibrate the fluxgate compass for any reason in the future, follow the procedures in the autopilot owner's handbook. 30 Pathfinder Smart Heading System - Owner's Handbook A. 2 Integrating with other Raymarine autopilots Connecting to Autopilots If you already have a Raymarine fluxgate compass mounted in a suitable location as part of your autopilot system (not T150/T400), you need to: · · · install GyroPlus 2 unit and connect the existing SeaTalk system to the SeaTalk terminals on the GyroPlus 2 unit re-route the compass cable and connect it to the FLUXGATE inputs on the GyroPlus 2 unit use the autopilot control head or Pathfinder Plus to re-calibrate the compass (see either the autopilot owner's handbook or Chapter 3: Calibration in this handbook for more details) The GyroPlus 2 unit will then output: · · an accurate, stabilized heading on SeaTalk for the autopilot fast heading data on NMEA for the Pathfinder Plus functions CAUTION: If you are using the Smart Heading System as the primary heading reference for an autopilot, you must ensure that it receives power (via SeaTalk or direct from the distribution panel) even if the Pathfinder Plus is switched off.
