IS12 Wind Speed/Angle 1 GENERAL 1.1 Introduction The Simrad IS12 System is a flexible modular series of instruments that offer large, clear displays, easy to operate functions and robust, weatherproof construction. Whether as a stand alone instrument, or as part of a networked navigation system, the IS12 Wind system will offer superb performance. LIGHT WIND ALARM TRUE APP INFO Fig 1.
Instruction Manual 1.2 IS12 Network System The IS12 system is built around a high speed bus networking system that allows instruments to be easily interconnected and share data. All units are interconnected and powered using a standard single cable (Fig 1.2) - COMPASS Tx WIND Tx MEGA DATA WIND SPEED/LOG DEPTH COMPASS CONTROLLER ALARM Fig 1.
IS12 Wind Speed/Angle 2 OPERATION 2.1 Apparent Wind Angle When the IS12 Analogue Wind instrument is switched on, the apparent wind angle is shown as an analogue readout (Fig 2.1) - LIGHT WIND ALARM TRUE 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.
Instruction Manual 2.3 High Wind Alarm The Analogue Wind instrument features an alarm that can be set to sound if the wind speed goes above a specified value. Press the WIND ALARM key. The display will show ALM briefly, then change to the current wind alarm setting (Fig 2.3) - LIGHT WIND ALARM TRUE APP INFO Fig 2.
IS12 Wind Speed/Angle 2.4 True Wind Angle & Speed The Analogue Wind instrument can also show true wind angle and wind speed information, but boat speed information will be required in order for this to be calculated, which can be supplied by an IS12 Speed Log or Combi instrument (Fig 2.4) Speed Log/Combi Analogue Wind Masthead Transducer Speed Transducer Fig 2.
Instruction Manual 2.5 Digital Close Hauled Display The Wind Angle can also be displayed digitally - pressing the INFO key switches between the wind speed and close hauled wind angle digital displays (Fig 2.6) - LIGHT WIND ALARM TRUE APP INFO LIGHT WIND ALARM TRUE APP INFO Fig 2.6 - Switching to Digital Close Hauled Display When showing the close hauled wind angle, the graphic on the left of the display indicates the direction of the wind.
IS12 Wind Speed/Angle 2.6 Backlighting The backlighting illuminates the display and the keys, with five levels of brightness. To switch the backlighting on, press the LIGHT key. The display will illuminate and the digital display will show the current lighting level (Fig 2.9) - LIGHT WIND ALARM TRUE APP INFO LIGHT WIND ALARM TRUE APP INFO Fig 2.9 - Turning Backlighting On Two icons will be shown on the bottom line of the display ( and ), corresponding to the WIND ALARM and TRUE/APP keys.
Instruction Manual 2.7 Remote Control / Alarm Option The optional remote control allows all functions of each instrument to be remotely controlled. Any alarms sounded are also repeated on this unit. See Section 3.6 regarding enabling and disabling remote control functionality for this instrument. As this unit is intended to control all instruments in the IS12 range, the keypad is a generic design. Fig 2.
IS12 Wind Speed/Angle 3 CALIBRATION To protect the calibration functions, these are held in a hidden menu. To enter calibration mode, press and hold the LIGHT key. The digital display will show CAL briefly, then change to UNIT (Fig 3.1) LIGHT WIND ALARM TRUE APP INFO LIGHT WIND ALARM TRUE APP INFO Fig 3.1 - Entering Calibration Mode Once in calibration mode, pressing the (WIND ALARM) or (TRUE/APP) keys will cycle through the available calibration options - Units (Section 3.
Instruction Manual 3.1 Selecting Units Enter calibration mode and press (INFO). The wind speed units can then be selected (knots, metres/sec, miles per hour or Beaufort) by pressing the or keys (Fig 3.2) - LIGHT WIND ALARM or TRUE APP INFO Fig 3.2 - Selecting Wind Units NOTE E04054 Press (INFO) to set the selected wind units. Press point.
IS12 Wind Speed/Angle 3.2 Transducer Orientation For some installations, it may be necessary to mount the masthead transducer facing aft, rather than forward as is usual. If this is the case, the following procedure should be followed to avoid the displayed wind angle being 180º out. Enter calibration mode, press ADJ) and press (INFO). once (the display will show The display will show FORE, indicating that the Analogue Wind instrument is calibrated for the standard masthead installation.
Instruction Manual 3.3 Wind Angle Offset If the masthead transducer has not been fitted so that it is pointing precisely fore-aft, it will be necessary to adjust the displayed wind angle so that it is correct. Enter calibration mode, press twice (the display will show OFST - Fig 3.4) and press (INFO). LIGHT WIND ALARM LIGHT WIND ALARM or TRUE APP INFO TRUE APP INFO Fig 3.4 - Entering Wind Angle Offset The display will show the current wind angle as read from the masthead transducer.
IS12 Wind Speed/Angle 3.4 Local & Network Backlighting The instrument backlighting can be set so that any changes to the backlighting are duplicated across all IS12 instruments installed on the boat (Network), or so that any changes are limited to this specific instrument only (Local). NOTE The IS12 instruments are set to Networked lighting as default. Enter calibration mode, press three times (the display will show LIGHT) and press (INFO).
Instruction Manual 3.5 Shop Mode This is a simulation mode for in-store demonstration - do not use. 3.6 Disable Remote Control On some installations which includes the IS12 Remote Control, it may be more convenient to limit remote control access to only some instruments on the network - for example on a sailboat with a set of cockpit instruments and chart table repeaters, it would not be desirable to be able to remote control the instruments on the chart table (Fig 3.
IS12 Wind Speed/Angle 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 Fig 4.1 - Front Mounting 35mm (1.4in) minimum Front mounting (Fig 4.1) is the standard method of fitting and is the most straightforward.
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. NOTE 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.
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.
Instruction Manual 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.
IS12 Wind Speed/Angle 35mm (1.38”) BOW 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 20mm (0.
Instruction Manual 4.2.4 Attaching / Removing the Transducer The masthead transducer is attached to the masthead bracket using a simple quick-release clamp system. 1 - Slide the locating pegs on the rear of the transducer base into the slots on the masthead bracket. 2 - Rotate the transducer down onto the masthead bracket. 3 - The transducer base will then lock into place (Fig 4.12) - 1 2 3 Locating Peg Lock Fig 4.
IS12 Wind Speed/Angle 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.
Instruction Manual A three way joiner (part no. SDJ) is available as a separate accessory (Fig 4.16) - Three Way Joiner SDJ 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) - Fig 4.
