Failure to do so could result in personal injury, damage to your boat and/or poor product performance. WARNING: Electrical safety Make sure you have switched off the power supply before you start installing this product. WARNING: Although we have designed this product to be accurate and reliable, many factors can affect its performance. [. . . ] The transducer cable is connected to the rear of the instrument. For advice, or further information regarding the installation of these products, please contact the Raymarine Product Support Department or your own National Distributor. 3. 1 Planning your installation Before starting the installation, spend some time considering the best positions for both transducer and instrument, such that the Site requirements and the EMC installation guidelines are satisfied. Site requirements Transducer For optimum performance, the Fluxgate Compass transducer should be positioned as near as possible to the pitch/roll center of the vessel, as shown in the following illustration. 0. 3L to 0. 5L L X 0. 3L to 0. 5L L D4431-2 14 ST60 Compass Instrument Owner's Handbook The Fluxgate Compass transducer must also be sited: · At least 0. 8 m (2 ft 6 in) away from the vessel's steering compass to avoid deviation in both compasses. · On a bulkhead below deck. Note: On steel vessels the Fluxgate Compass transducer can be mounted above deck. When mounted above deck, performance may be impaired due to increased motion. · To allow reasonable access for installation and servicing. · Away from any equipment or other installation which may shield the transducer or otherwise disturb the earth's magnetic field, e. g. large ferrous or magnetic items, communications equipment or cabling. · On a vertical mounting surface. Where necessary, make up a suitable non-ferrous wedged packing piece to provide the necessary vertical surface. There must also be a viable route for the transducer cable to be routed to the instrument. 3 in (76 mm ) 3 in (76 mm ) Fluxgate Compass transducer dimensions D729-7 Instrument CAUTION: The presence of moisture at the rear of the instrument could cause damage either by entering the instrument through the breathing hole or by coming into contact with the electrical connectors. ST60 instruments can be fitted either above or below deck, provided the rear of the instrument is sited where it is protected from contact with water. Each instrument must also be positioned where it is: · Easily read by the helmsman. · Protected against physical damage. · At least 9 in (230 mm) from a compass. · At least 20 in (500 mm) from radio receiving equipment. · Reasonably accessible from the rear for installation and servicing.

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. 4. 85 in (123 mm) 3. 54 in (90 mm) diameter 4. 53 in (115 mm) 3. 54 in (90 mm) diameter 16 ST60 Compass Instrument Owner's Handbook For optimum EMC performance, it is recommended that wherever possible: · Raymarine equipment and cables connected to it are: · At least 3 ft (1 m) from any equipment transmitting or cables carrying radio signals e. g. 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. [. . . ] If a value is not present on SeaTalk, or if the instrument is not connected to SeaTalk, use the < and > keys to set the appropriate value. 30 ST60 Compass Instrument Owner's Handbook True/magnetic selection Use this option to select either MAG (netic) or TRUE as the heading display default (indicated by the black square adjacent to either MAG or TRUE , as appropriate). If theST60 Compass instrument is used in a system without a SeaTalk compatible Autopilot, or it is being used independently, set the digital display to MAG . True headings cannot be displayed if variation data is not available. Leaving User calibration Press the disp and lock keys for 2 seconds, to save your changes, exit User calibration and return to normal operation. 4. 3 Intermediate calibration The Intermediate calibration procedures (see the Intermediate calibration flow chart) enable you see: · Software version number. To access the intermediate calibration information, hold down the disp and lock keys together for approximately 4 seconds. Software version number This screen shows the Software Version number.
