1 Chapter 1: Operation Chapter 1: Operation 1.1 Introduction Your ST40 Speed instrument provides: • Speed information (current, maximum and average), in either knots (KTS), miles per hour (MPH) or kilometres per hour (KPH). • Log and trip information. These are given in either nautical miles (NM), statute miles (M) or kilometres (KM). • Water temperature information. This is given in either degrees Celsius (°C) or Fahrenheit (°F).

5 Chapter 2: Maintenance and Fault Finding Chapter 2: Maintenance and Fault Finding 2.1 Maintenance Servicing and safety • Raymarine equipment should be serviced only by authorised Raymarine service technicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no user-serviceable parts in any Raymarine product. • Some products generate high voltages, so never handle the cables/ connectors when power is being supplied to the equipment.
6 ST40 Speed Instrument Owner’s Handbook Instrument Certain atmospheric conditions may cause a small amount of condensation to form on the instrument window. This will not harm the instrument and will clear after the instrument has been switched on for a short period. Periodically clean your ST40 instrument with a soft damp cloth. Do NOT use chemical or abrasive materials to clean the instrument. Transducer Refer to the Installation and Maintenance instructions supplied with the transducer.

Check power supply. Check SeaTalk cabling and connector security. Action Check the condition of the transducer cable and the security of the connections.
8 ST40 Speed Instrument Owner’s Handbook SeaTalk information not being transferred between instruments For example, backlighting level changes implemented at one instrument do not affect other instruments Action Check security of SeaTalk connections between instruments. Check condition of SeaTalk cables. Isolate faulty instrument by disconnecting instruments one by one.
9 Chapter 3: Installation Chapter 3: Installation This chapter describes how to install the ST40 Speed instrument, and associated speed transducer. The transducer is fitted in the hull of the vessel and is connected to the rear of the instrument. 3.1 Planning your installation Determine the best positions for both transducer and instrument, such that the EMC installation guidelines and the Site requirements (below) are satisfied.
10 ST40 Speed Instrument Owner’s Handbook • The equipment is supplied from a different 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 specified cables are used at all times.
11 Chapter 3: Installation 57 mm (2.25 in) 51 mm (2.0 in) D4643-1 Note: If you intend fitting a nonstandard transducer, extra tools may be required Site requirements Transducer The transducer types required for the various hull types are as follows: Hull material Transducer type Glass reinforced plastic (GRP) Steel Aluminium M78712 Through hull plastic (supplied as standard) Wood M78716 Through hull bronze Other transducer types are also available for specific requirements.
12 ST40 Speed Instrument Owner’s Handbook The transducer should: • Be ahead of the propellers (by a minimum of 10% of the water line length ). • Be at least 150 mm (6 in) away from the keel (ideally ahead of the keel if a sailing yacht). • Be as near as possible to the centre line of the vessel. • Be clear of other through-hull fittings or projections. • Have sufficient clearance inside the hull to fit the nut. • Have 100 mm (4 in) of headroom to allow for withdrawal.

14 ST40 Speed Instrument Owner’s Handbook Running transducer cable Each transducer has a 9 m (30 ft) cable fitted with spade terminals for connection to the ST40 Speed instrument. Observing the following guidelines, run the cable to the instrument: • If the cable has to be fed through the deck, always use a good quality deck gland. • Where cables are fed through holes, always use grommets to prevent chafing. • Secure long cable runs so they do not present a hazard.

21 Chapter 4: Calibration Chapter 4: Calibration 4.1 Introduction The procedures in this Chapter must be carried out before the equipment is used operationally, to optimise the performance of the instrument with the vessel. Calibration information is presented in flow chart form. The flow charts show the various calibration screens and key presses necessary to carry out calibration. All key presses are momentary unless otherwise stated.
