Chapter 1: Introduction 7 Chapter 1: Introduction Congratulations on the purchase of your Autohelm ST30 Compass. The compass displays heading information directly from the fluxgate compass or, if the unit is used as a repeater, via the SeaTalk bus using data taken from another compass instrument or autopilot. The compass can also be used as a steering indicator to maintain a given course. Any helmsmans error, to port or starboard, is indicated by a bargraph at the bottom of the display.
ST30 Compass Installation and Operation Handbook 8 Important Information All Autohelm equipment and accessories are designed to the highest standard for use in the leisure marine environment. Their design and manufacture conforms to the latest Electromagnetic Compatibility (EMC) standards, but good installation is required to ensure that performance is not compromised.
Chapter 2: Installation 9 Chapter 2: Installation This chapter covers installation of the fluxgate compass and the display head. Please read these instructions thoroughly before you attempt to install the display head and fluxgate compass. 2.1 Compass Installation Options The ST30 Compass can be used in one of the following ways: ❏ as a stand alone system comprising of display head and fluxgate compass with an independent power supply. Heading data is sent directly to the compass display head.
ST30 Compass Installation and Operation Handbook 10 ❏ as a repeater for an autopilot compass. Power and data is received via SeaTalk.

With a hand bearing compass fixed to the proposed bulkhead, turn your vessel through 360° and check that the difference between the hand bearing compass and the ships compass does not exceed 10° on any heading. If difference does exceed 10° you will have to select a new location. 2. Once you have selected a suitable location, attach the fluxgate compass to the bulkhead using the four self-tapping screws provided. 3.

Chapter 2: Installation 15 2.5 Trunnion Mounting the Display Head The display head may also be trunnion mounted using the custom Autohelm mounting kit (part number D219). D1793-1 Note... Because the ST30 Compass breathes around the integral connector pins, trunnion mounted instruments must be sited in areas protected from the weather and direct contact with water. 2.6 Power supply (Stand-alone operation) Caution: The ST30 Compass is for use with 12V supplies only.
ST30 Compass Installation and Operation Handbook 16 2.7 Power supply & Data Transfer (SeaTalk system) When the ST30 Compass is part of a SeaTalk system, power and data is transmitted via the daisy-chain cable or one of the Standard Autohelm SeaTalk Extension or Interface Cables.
Chapter 3: Calibration 17 Chapter 3: Calibration 3.1 About this Chapter Before the ST30 Compass system can be used as a navigational aid, the fluxgate compass MUST be linearised to compensate for deviation and the displayed heading MUST be aligned to a known transit bearing. Other calibration features allow you to adjust the speed at which the heading and heading error displays are updated. 3.2 User Calibration User calibration contains features to perform compass linearisation and heading alignment.

Chapter 3: Calibration 19 LOCK HEADING AVERAGE Cal Dev COMPASS D1856-1 LOCK Please note... If the deviation exceeds 10° the fluxgate compass should be resited. Heading Alignment Once the compass has been successfully linearised, you must match the displayed heading to a known transit bearing. 1. From the compass deviation display, simply press advance to heading alignment. or to 2. Press the or key to adjust the displayed heading to match the known transit bearing.
ST30 Compass Installation and Operation Handbook 20 3.3 Linearisation and Heading Alignment when used with a SportPilot Because the Autohelm SportPilot does not have a digital read-out, the ST30 Compass can be used to repeat heading information received from SportPilot fluxgate compass. To display accurate heading information, the SportPilot fluxgate compass must be linearised and then aligned to a known transit bearing as described in section 3.2. Please note...
Chapter 3: Calibration 21 2. Press and momentarily to enter extended calibration. LOCK HEADING AVERAGE Cal COMPASS D1851-1 LOCK Calibration ON/OFF This feature is used to restrict access to the user calibration menu to prevent accidental adjustment of the linearisation and heading alignment features.

Chapter 3: Calibration 23 Off-Course Bargraph Damping This feature controls the rate at which the off-course bargraph is updated. The factory default setting is 4 which can, if so required, be adjusted using the or key. The higher the value displayed the slower the screen update of the bargraph.

Chapter 4: Operation 25 Chapter 4: Operation 4.1 General This chapter describes the operational features of the ST30 Compass using sample displays and text references. Points to remember... All key presses are confirmed by a single beep. This audible confirmation cannot be turned off. The ST30 Compass cannot receive or transmit NMEA data directly. If linearisation has not been carried out, the small CAL legend flashes for 1 minute every time the ST30 Compass is powered up.

LOCK HEADING AVERAGE N COMPASS D1796-1 LOCK The off-course bargraph consists of 5 port and 5 starboard segments plus the arrow head, which indicates a course error of 2°. The 5 segments indicate course errors of 4°, 7°, 11°, 16°, and 22°.

Chapter 5: Fault Isolation & Maintenance 31 Chapter 5: Fault Isolation & Maintenance 5.1 Fault Isolation In the unlikely event that a fault occurs with your ST30 Compass, the following table should help you identify the most likely cause and provides the action required to correct a fault. Fault Cause Action Compass display is blank. No power supply Check the cables are plugged in and are secure. Check the fuse/circuit breaker. Displayed heading is different from the ships compass.
32 ST30 Compass Installation and Operation Handbook 5.2 Maintenance Certain atmospheric conditions may cause condensation to form on the display head window. This will not harm the instrument and can be easily cleared by switching the lights on to level 3 (L3). Chemical and abrasive materials must not be used to clean the compass instrument; if it is dirty, clean it with a soft, damp cloth.
