These instructions should be read thoroughly before any attempt is made to install the speed sensor. General Points to Remember The speed sensor should be installed so that it is: · Ahead of the propellers. · At least 150mm (6in) from the keel and ideally forward of the keel. D587 · Near the centre line of the vessel. · Clear of all through hull fittings and projections. There should also be sufficient space above the sensor to allow the paddle wheel assembly to be removed. Alternative active transducers are available from your Autohelm dealer. The range includes: bronze through hull speed and a transom mount triducer. 4 ST80 Active Speed & Depth Transducer Installation 1. 2 Installing the Depth Sensor Procedures for fitting the sensor to the hull of your vessel are supplied in the sensor package. Please read these instructions thoroughly before attempting to install the unit. General Points to remember A warning label covers the face of the depth sensor. This label should be removed before use and the face of the sensor "wetted" with a household detergent. The sensor should be installed so that it is: · near the centreline of the vessel (within 10° of the vertical) 10 Max D630 · ahead of the propellers and forward of the keel · clear of all other through hull fittings or projections ST80 Active Speed & Depth Transducer Installation 5 1. 3 Installation of the Data Processing Unit The cables from the data processor are 2m (6ft) in length. Therefore, a 3-way SeaTalk connector block must be sited within 4m (12ft) of the transducer. Use the 19mm (3/4in) self-tapping screws to mount the processor vertically or horizontally to a springer or beam. D2345-1 Note: Position both the data processor and the SeaTalk connector block clear of any bilge water. 1. 4 Connection to SeaTalk Plug the free end of the data processor cable into any 3-way connector block.

Triducers provide speed, depth and temperature information and comprise of two data processors and a triducer housing. Please refer to the instructions provided in the triducer package for details on how to install the triducer housing. 8 ST80 Active Speed & Depth Transducer Installation Connecting the Triducer to SeaTalk The data processors should be connected to SeaTalk as follows.

ST80 Active Speed & Depth Transducer Installation 9 Chapter 2: EMC and Servicing Guidelines 2. 1 Important information All Autohelm equipment and accessories are designed to the best industry standards for use in the leisure marine environment. Their design and manufacture conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but good installation is required to ensure that performance is not compromised. Although every effort has been taken to ensure that they will perform under all conditions, it is important to understand what factors could affect the operation of the product. 2. 2 Installation To avoid the risk of operating problems, all Autohelm equipment and cables connected to it should be: · At least 1m (3 feet) from any equipment transmitting or cables carrying radio signals, e. g. , VHF radios, cables and antennas. [. . . ] In general this will not damage the equipment but can lead to it resetting, or momentarily may result in faulty operation. 2. 4 Servicing and Safety · Autohelm equipment should be serviced only by authorised Autohelm service engineers. They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any Autohelm product. · Some products generate high voltages, and so never handle the cables/connectors when power is being supplied to the equipment. [. . . ]
