Page 3: Description
Hercules system. COMPASS UNIT One important feature of the Super Halcyon 3 is its ability to 'learn' the magnetic effect of the vessel on the compass and automatically apply deviation correction. By following the simple procedure detailed in Section 4 of this book. -
Page 4: Operation
OPERATION The compass system is activated by switching on the power supply. The compass automatically compensates for changes in the strength of the earth's magnetic field after calibration. The Super Halcyon 3 works in both the northern and southern hemispheres without modification. (See section 5 on automatic calibration). -
Page 5: Fault Location
Ensure that the ship's supply is connected to the compass. A voltage of between 10V and 30V should be present between pin 3 with the orange conductor (+ve) and pin 2 with the black conductor (—ve) of cable 135-0A-113 at the 18-way connector. Whilst operating correctly the Super Halcyon 3 emits a quiet high-pitched audible tone. -
Page 6: Installation
INSTALLATION MASTER COMPASS UNIT The main consideration with installation lies in selecting a suitable mounting position -this may be above or below decks. To take maximum advantage of the remote compass sensor, the mounting position should be chosen with the following points in mind. (a) FIXED MACHINERY AND FITTINGS Keep as far as possible from fixed machinery containing iron or steel. -

CONNECTIONS It should be noted that when Super Halcyon 3 is used with Hercules alone, power is derived directly from the Hercules Computer backplate. When the Super Halcyon 3 is used independently, the power supply should be connected to the ship's 12/24V dc supply via a 1A fuse. -
Page 8: Calibration
CALIBRATION The software in the compass allows the compass to 'learn' the magnetic fields in the vessel that are causing the deviation errors. By following the simple procedure below, deviation errors are reduced to an insignificant level. AUTOMATIC CALIBRATION Align the markings on the top of the compass approximately with the fore-and-aft line of the vessel by rotating the compass unit within its mounting bracket. -
Page 9: Compass Calibration Procedure
Compass Calibration Procedure (1) At a speed of about three knots, and away from any large steel structures, slowly motor the boat through a full circle (360°) taking 6-10 minutes to complete circle. The calibration takes place during this time. Continue to turn to complete a further half circle (180°). It is helpful to have a watch with seconds running and a compass or repeater in front of the helmsman. -

TECHNICAL DATA The main output from the Super Halcyon 3 can be connected directly with the B&G Hercules system. It can also drive the analogue repeater compass directly. Three other outputs are available from the standard compass (386-00-009) to interface with a wide range of autopilots, radars, position fixers, computers etc. - Page 11 SPECIFICATION GENERAL The Super Halcyon 3 sensor unit and the analogue compass repeater are fully sealed for use in marine conditions. PERFORMANCE Sensor Accuracy (when properly adjusted): + 1° max. error at 0° heel + 2° max. error at 20° heel + 3°...
