User manual RAYMARINE LINEAR RUDDER REFERENCE TRANSDUCER INSTALLATION GUIDE

[. . . ] © Raymarine Ltd 2001. Installation Guide 3 Introduction Product description The linear rudder position sensor (part number: M81188) is designed for `bullhorn' style hydraulic outboard steering systems. It is totally weatherproof and designed to be mounted on the bullhorn ram. It transmits the precise position of the boat's rudder to the autopilot. 425 mm (16. 75 in) 32 mm (1. 3 in) D5389-1 Linear rudder position sensor - dimensions Parts supplied The linear rudder position sensor package contains: · · · · · · · this installation guide linear rudder position sensor spacers (x2) 80 mm (3. 1 in) hose clamps (x2) U-bracket M8 nut and washer female spade connectors (x4) 4 Linear Rudder Position Sensor Mounting Starboard bolt End bracket Bullhorn ram shaft Nut and washer Threaded rod Sensor shaft U-bracket Sensor shaft Sensor barrel Alignment mark Sensor barrel Cable Hose clamp Spacer Bullhorn ram D5390-1 1. If necessary, release the hydraulic pressure from the boat's hydraulic steering system Note: Contact your steering gear manufacture for advice on this step, and follow their instructions for releasing the hydraulic pressure. [. . . ] Connect to the RUDDER terminals on the autopilot or course computer, as described in the owner's handbook. Note: To allow for the bullhorn's movement, leave a loop of cable at the end of the linear rudder position sensor. If the standard cable is not long enough, your Raymarine dealer can supply a 10 m (30 ft) extension cable (part number: D173). Post installation checks When you have connected the sensor to your autopilot, pressurize the steering system (if required). When you have done this, check the sensor's operation as described in the autopilot owner's handbook. 6 Linear Rudder Position Sensor Raymarine EMC Guidelines EMC Installation & Service Guidelines IMPORTANT NOTE All Raymarine equipment and accessories are designed to the best industry standards for use in the leisure marine environment. When powered up, all electrical equipment produces electromagnetic fields. These can cause adjacent pieces of electrical equipment to interact with one another, with a consequent adverse effect on operation. In order to minimise these effects and enable you to get the best possible performance from your Raymarine equipment, these guidelines are provided to enable you to ensure minimum interaction between different items of equipment, i. e. The design and manufacture of Raymarine equipment and accessories conform to the appropriate EMC standards, but correct 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. Please keep this document for future reference. Safety Some products generate high voltages, so never handle the cables/connectors when power is being supplied to the equipment. Installation These guidelines describe the conditions for optimum EMC performance, but it is recognised that it may not be possible to meet all of these conditions in all situations. To ensure the best possible conditions for EMC performance within the constraints imposed by any location, always ensure the maximum separation possible between different items of electrical equipment. For optimum EMC performance, it is recommended that wherever possible: · Raymarine equipment and cables connected to it are: · At least 1 m (3 ft) from any equipment transmitting or cables carrying radio signals e. g. In the case of SSB radios, the distance should be increased to 2 m (7 ft). A radar beam can normally be assumed to spread 20 degrees above and below the radiating element. · The equipment is supplied from a separate battery from that used for engine start. Voltage drops below 10 V in the power supply to our products, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode. Raymarine EMC Guidelines · · Raymarine specified cables are used at all times. Cutting and rejoining these cables can compromise EMC performance and so must be avoided unless doing so is detailed in the installation manual. If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position. Suppression Ferrites The following illustration shows typical cable suppression ferrites fitted to Raymarine equipment. [. . . ] Magnetrons, Cathode Ray Tubes (CRT), TFT Liquid Crystal Displays (LCD) and cold cathode fluorescent lamps (CCFL), hailer horns and transducers are warranted for 1 year/12 months from date of sale. All costs associated with transducer replacement, other than the cost of the transducer itself, are specifically excluded from this Warranty. Overtime premium labor portion of services outside of normal working hours is not covered by this Warranty. Travel cost allowance on certain products with a suggested retail price below $2500. 00 is not authorized. [. . . ]
