EMC installation guidelines All Raymarine equipment and accessories are designed to the best industry standards for use in the recreational marine environment. Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but correct installation is required to ensure that performance is not compromised. Although every effort has been taken to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of the product. The guidelines given here describe the conditions for optimum EMC performance, but it is recognized that it may not be possible to meet all of these conditions in all situations. To ensure the best possible conditions for EMC performance within the constraints imposed by any location, always ensure the maximum separation possible between different items of electrical equipment. For optimum EMC performance, it is recommended that wherever possible: • Raymarine equipment and cables connected to it are: 81175_7.book Page 10 Monday, March 7, 2016 2:39 PM 10 • At least 3 ft (1 m) from any equipment transmitting or cables carrying radio signals e.g. VHF radios, cables and antennas. In the case of SSB radios, the distance should be increased to 7 ft (2 m). • More than 7 ft (2 m) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element. • The equipment is supplied from a separate battery from that used for engine start. Voltage drops below 10 V, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode. • Raymarine specified cables are used. Cutting and rejoining these cables can compromise EMC performance and must be avoided unless doing so is detailed in the installation manual. • If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position. Suppression ferrites The following illustration shows typical cable suppression ferrites used with Raymarine equipment. Always use the ferrites supplied by Raymarine. This product has ferrites mounted internally. D3548-2 Figure 3: Typical suppression ferrites Connections to other equipment If your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine, a suppression ferrite MUST always be attached to the cable near to the Raymarine unit. 81175_7.book Page 11 Monday, March 7, 2016 2:39 PM 11 2. Mounting the drive Mounting the drive unit involves four main steps: • • • • ensuring correct drive alignment securing the drive to the boat connecting the drive to the steering system completing a steering check Drive alignment When mounting the linear drive unit, check that it is aligned correctly: • The main drive assembly must be at right angles to the mounting surface (see Figure 4 ). • The drive unit must be at right angles to the tiller arm when the rudder is amidships (see Figure 4 ).

The ball end fitting only allows up to 5 degrees misalignment between the push rod and tiller arm plane of rotation (see Figure 5 ). CAUTION Alignment Accurate angular alignment is extremely important. You must not exceed this +/- 5 degree limit under any circumstances. 81175_7.book Page 12 Monday, March 7, 2016 2:39 PM 12 5º Max. 5º Max. D5078-1 Figure 5: Alignment between push rod and tiller arm plane of rotation Securing the drive Mounting location Before you secure the drive to your boat, you must first check the suitability of the mounting location. CAUTION Mounting location Consult the boat manufacturer if you have any doubt about the strength or suitability of the mounting location. • Structural strength: • This drive produces a considerable amount of force, so you must mount it on a solid structure (i.e. a substantial frame member) in the boat. In some cases you may need to build a special frame to mount the drive unit. • To prevent excess noise and vibration, do not attach this drive to any structures that support cabins. • Drive orientation: • You can attach the drive unit mounting foot to any suitable horizontal or vertical surface. If required, you can also mount the drive unit upside down. • General position: • Refer to the EMC installation guidelines (page 9) • Make sure the drive will be accessible for future servicing. • Environment: • This drive is not waterproof, so you should mount it in a dry location, clear of any bilge water. 81175_7.book Page 13 Monday, March 7, 2016 2:39 PM 13 Securing bolts Attach the mounting foot with four stainless steel M10 (3/8 inch) bolts and lock nuts/lock washers. Note: Always mount the drive as securely as possible to make sure it performs reliably and remains correctly aligned. Connecting to the steering system CAUTION Equipment strength Consult the steering gear manufacturer if you have any doubt about the strength of the existing tiller arm or rudder quadrant. This drive produces a considerable amount of force, so you must ensure that your tiller arm or rudder quadrant can cope with the peak thrust specified in the Table 1-1, Drive specifications. Use one of these methods to attach the push rod to the rudder stock: 1. Independent tiller arm: we recommend that you attach the linear drive unit to the rudder stock via an independent tiller arm (the Edson and Whitlock companies offer standard fittings for their steering systems). 2. Steering linkage tiller arm or rudder quadrant: in certain cases, you may be able to attach the push rod to the same tiller arm or rudder quadrant used by the main steering linkage. Consult the steering manufacturer before you modify the rudder quadrant. Attaching the rod end Use the supplied tiller pin assembly to attach the rod end to the tiller arm, at the tiller arm radius shown in Figure 4 . 1. Attach the tiller pin to the tiller arm: • insert the tiller pin through the tiller arm hole, so the flange remains above the arm (see Figure 6 ) • make sure that the tiller pin is a tight fit in the tiller arm • use the supplied lock washer and fully tighten the lock nut Note: If necessary, you will need to drill a 13 mm (0.52 in) hole in the tiller arm at the radius shown in Figure 4 . 2. Attach the rod end to the tiller pin: • place the rod end onto the tiller pin • secure with the supplied washer and R-clip (see Figure 6 ) 81175_7.book Page 14 Monday, March 7, 2016 2:39 PM 14 R-clip Washer Rod end Flange Tiller arm Lock nut Lock washer Tiller pin Hole diameter 13 mm (0.52 in) D5076-1 Figure 6: Attaching the push rod to the tiller arm Steering check When you have mounted the drive unit, turn the boat’s steering wheel from hardover to hardover and check that: • Angular movement of the ball end fitting is less than 5 degrees (see Figure 5 ). If you exceed this 5 degree limit, the drive will catch on the tiller arm/rudder quadrant and the ball joint will bind. • No part of the drive unit fouls the boat’s structure when the push rod moves in and out. • The total rudder movement is limited to +/- 35 degrees by the steering system end stops rather than the linear drive’s end limits (see Figure 7 ). Steering system end stop Steering system end stop 35º 35º D5079-1 Figure 7: Total rudder movement CAUTION Linear drive Make sure rudder movement is limited by the steering system end stops before the push rod reaches its end stop. Failure to do this could damage the drive and will invalidate the warranty. 81175_7.book Page 15 Monday, March 7, 2016 2:39 PM 15 WARNING Moving parts Keep clear of moving steering systems at all times. Protect moving parts from access during normal use. 3. Connecting to the course computer WARNING Electrical safety Make sure the power supply is switched OFF before you make any electrical connections. The linear drive unit has electrical connections for: • the drive motor: two single-core cables: red and black • the clutch: a two-core cable with red (+) and blue (-) cores Follow these steps to connect the linear drive to the course computer: 1. Measure the distance of cable run from the drive unit to the course computer: • use Table 1-1 to identify the appropriate motor cable size • use at least 1.5 mm2 (16 AWG) copper cable for the clutch 2. Join these cables to the drive cables using appropriate electrical connectors or junction boxes at the correct power rating. 3. Route the cables back to the course computer, taking into account the EMC installation guidelines (see page 9). 4. Connect the cables to the course computer (see Figure 8 ): • CLUTCH cable: red core to +ve, blue core to -ve • MOTOR cables: at this stage you can connect either motor cable to either terminal. You will check these connections after installing the rest of the autopilot system. 81175_7.book Page 16 Monday, March 7, 2016 2:39 PM 16 12V POWER 24V A CLUTCH B GROUND MOTOR D13527-1 Figure 8: Cable connections at SPX or ACU course computer Table 1-1: Recommended cable sizes Cable length (drive unit to course computer) Cable gauge (AWG) Copper area (mm2) Type 1 drive up to 3m (10ft) up to 5m (16ft) up to 7m (23ft) up to 10m (32ft) up to 16m (52ft) 14 12 10 8 6 2.5 4 6 10 16 Type 2 drive 12 V (short/ long) up to 5m (16ft) up to 7m (23ft) up to 16m (52ft) 10 8 6 6 10 16 Type 2 drive 24 V (short/ long) up to 3m (10ft) up to 5m (16ft) up to 10m (32ft) up to 16m (52ft) 12 10 8 6 4 6 10 16 4. Post installation checklist Check the following points after installing the drive: 1. Is the mounting foot secured to a substantial structure on the boat? 2. Is the drive unit correctly aligned, i.e: • Is the mounting foot correctly oriented? 81175_7.book Page 17 Monday, March 7, 2016 2:39 PM 17 • Is the drive mounted at right angles to the tiller arm, in a mid-stroke position, when the rudder is amidships? • Is the push rod accurately aligned with the tiller arm plane of rotation (less than 5 degrees variation)? 3. Is the linear drive rod end: • securely attached to the tiller arm or quadrant? • attached at the recommended tiller arm radius for the boat? 4. Are the motor and clutch cables correctly routed and securely connected to the course computer? 5. Have you completed a hand-steering check (see page 14)? Note: When you have installed the entire autopilot system, you will need to complete an autopilot steering check. Refer to the control unit handbook for more details. Maintenance Please make the following checks before each passage: • • • • Ensure that all connections and mountings are secure. Ensure that the drive is aligned correctly. Ensure that cables have no signs of wear or damage. Check for unusual noisy operation, such as clicking or grinding noises, or unusual vibration. If any of these are detected, the drive must be taken to a Raymarine authorized service representative before further use. • Ensure that the drive is not wet or exposed to water. • Ensure that the swivel joint and rose-end are lightly greased with waterproof grease. Note: The drive should be serviced every 2 years or 1000 hours of use, whichever comes first, by a Raymarine authorized service representative. EMC servicing and safety guidelines • Raymarine equipment should be serviced only by authorized Raymarine service representitives. They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any Raymarine product. • Some products generate high voltages, so never handle the cables/connectors when power is being supplied to the equipment. • When powered up, all electrical equipment produces electromagnetic fields. These can cause adjacent pieces of electrical equipment to interact with one another, with a consequent adverse effect on operation. In order to minimize these effects and enable you to get the best possible performance from your Raymarine equipment, guidelines are given in the installation instructions, to enable you to ensure minimum interaction between different items of equipment, i.e. ensure optimum Electromagnetic Compatibility (EMC). 81175_7.book Page 18 Monday, March 7, 2016 2:39 PM 18 • Always report any EMC-related problem to your nearest Raymarine dealer. We use such information to improve our quality standards. • In some installations, it may not be possible to prevent the equipment from being affected by external influences. In general this will not damage the equipment but it can lead to spurious resetting action, or momentarily may result in faulty operation.
