[. . . ] 0 1 2 Introduction Thank you for choosing FI-30 Wind Data instrument. We are convinced that you will appreciate all the valuable information either you are a cruiser or a racer. It is important that you are following this instruction regarding installation and operation. If the instrument are to be used in a Nexus Network, there are some systems settings that are dependent on where the transducers are installed, i. e. [. . . ] This steer function will give course to steer, true or magnetic relative bearing to Waypoint, including compensation for drift. It must be used together with a GPS or Decca/ Loran C navigator connected to the NEXUS network (at the Server instrument). The text [OFF], [MEM] or the previous selected function is flashing, select [CTS] and press SET. Even if your Compass is un-deviated, the CTS function will anyway tell you the optimum course to sail !The CTS function gives you the shortest way to sail towards the Waypoint. Tide must however be taken into consideration, since it will give a time dependant drift on the boat. 20 4. 5. 7 Tactical use of [MEM] Function [MEM] is used to discover the smallest of wind shifts during upwind or downwind sailing, but it is your tactical decision wheter to tac or to stay on course. The Compass Data instrument will automatically keep track on wheter you are using the starboard or port MEM if the course difference between each trim is more than 45°. There is also a new function called [KTR] (Knock TimeR), giving you the time spent i seconds when sailing below a preset "knock Angle". Both [MEM] and [KTR] will help you to get a very good "picture" over actual windshifts, both in size and time. On the optimum compass heading, press the trim or SET button to store your present course in the memory called MEM. Your actual course is then constantly compared with MEM and displayed as a lift or as a header. How to use the MEM function: When you are sailing at a good speed and with the sail trimmed, press trim or SET. The Compass Data will then store the present course in memory MEM as a reference. If you then have a lifter, press TRIM again, but if you have a header more then 5°-10°, tack. After you tack, re-trim the sails and get a good boat speed before you press trim or SET again. Whenever you get a lifter, press TRIM, but when you get a header, tack. Your previous trim reference will automatically be displayed and used. This is done by setting the CAL value C-17 to the maximum angle where you consider your boat to be pushed off course, i. e. 4. 5. 8 Battery voltage [BAT] The text [BAT] will display battery voltage. The voltage is measured inside the instrument and will not compensate for any voltage drop caused by installation. 4. 5. 9 Boat speed [BSP], option The text [BSP] will display boat speed (water speed). As an option, you may add or remove displaying boat speed [BSP], trip log [TRP] and water temperature [TMP]. [. . . ] At least once a year, check all your connections and apply additional silicon paste at each connection point. Storing transducers and instruments when not in use for longer periods: It is advisable to remove the instruments and transducers, and store them inside the boat or at home in room temperature, if possible. 6. 2 Fault finding Before you contact your FI-30 dealer, and to assist your dealer to give you a better service, please check the following points and make a list of: · All connected instrument and transducers, including their software versions. · Nexus Network ID numbers for each instrument (displayed at power up). 6. 2. 1 General In most cases, the reason for faults in electronic equipment is to be found in poor installations.
