Preface Important information WARNING Although your Heading Sensor is designed to give accurate and reliable performance, it should serve only as an aid to navigation and should never lead to the erosion of good seamanship. Always maintain a permanent watch and be aware of situations as they develop.
Chapter 1: Introduction Chapter 1: Introduction Thank you for purchasing a Raymarine product. We are sure your Heading Sensor will give you many years of trouble-free operation. This Heading Sensor is designed to provide reliable performance, even under the most demanding conditions.
• Examine the cable for signs of damage, such as chafing, cuts or nicks • Make sure that the Heading Sensor is still attached securely to the bulkhead 124_3c02.p65 09/05/01, 11:30...
All Raymarine products are subjected to comprehensive test and quality assurance programmes, prior to packing and shipping. However, if your Heading Sensor should develop a fault , please refer to the following table to identify the most likely cause and the corrective action required to restore normal operation.
• Self tapping screws (4) • 6ft (2m) cable, with molded Heading Sensor plug on one end If you are installing the Heading Sensor at a distance from an NMEA instrument or system, you may also need a 16.25ft (5m) NMEA accessory cable.
This will not damage the equipment, but may cause the loss of some information and may change the operating mode. • Raymarine specified cables are used. Cutting and rejoining these cables can compromise EMC performance and must be avoided unless doing so is detailed in the installation manual.
Raymarine unit. 3.2 Siting the Heading Sensor The Heading Sensor must be fitted to a vertical or horizontal bulkhead (preferably forward facing), away from large ferrous objects such as the engine and other magnetic devices.
(3) provided. The embossed arrow on the back of the bracket must be pointing skywards. Note: The Heading Sensor must be within 10° of the vertical and, ideally, positioned at the pitch and roll centre of the vessel.
6. Pass the Allen bolt (2) through the aperture in the top of the Heading Sensor mounting bracket (4) and tighten using the Allen key supplied. Note: You may need to loosen this later to adjust the Heading Sensor alignment , as described in Chapter 4, Calibration. 3.4 Connection Procedure...
Chapter 4: Calibration Chapter 4: Calibration 4.1 Introduction The Raymarine Heading Sensor must be calibrated to ensure that the transmitted compass heading information is accurate. This procedure should be carried out before the unit is used as a navigational aid.
1. Loosen the Heading Sensor mounting slightly, so that you can rotate the sensor. To do this, use the Allen key supplied with the Heading Sensor to loosen the Allen bolt in the top of the Heading Sensor mounting bracket (see page 7).

Chapter 4: Calibration 2. If the Heading Sensor’s readings are less than the actual readings, rotate the sensor slightly clockwise. If the Heading Sensor’s readings are greater than the actual readings, rotate the sensor slightly anti-clockwise. 3. Check the headings again, and repeat step 2 if required.
Specification Heading Sensor Specification Dimensions: Power Supply: Power Consumption: Operating Temperature: Weight: Compatability: Accuracy: Gimbal Range: Data Output (NMEA): (10Hz) 124_3spe.p65 90mm x 100mm x 130mm (3.5in x 3.9 in x 5.1in) 10 to 16V DC 40mA -10°C to +70°C (14°F to 158°F)
During this period, except for certain products, travel costs (auto mileage and tolls) up to 100 round trip highway miles (160 kilometres) and travel time of 2 hours, will be assumed by Raymarine only on products where proof of installation or commission by authorized service agents, can be shown.
