Whether a second ring main is required can be determined from the following: Cable run upto 10m (33ft) Single connection: Second connection: Single connection: Second connection: 13 instruments maximum 26 instruments maximum 7 instruments maximum 13 instruments maximum Chapter 2: Transducer Installation 2. 1 Connection to the Control Head The ST50 PlusTridata is supplied with depth and speed transducer cable tails and connectors. These cable tails plug into the mating connectors fitted to the 14m (45ftI depth and speed transducer cables. Cable run upto 20m (66ft) The second ringmain should be connected to the spare lead on the last instrument in the chain and directed back to the circuit breaker. . 7 Connection to SeaTalk Compatible Autopilots lf the installation includes a SeaTalk compatible Autopilot the ST50 Plus instruments may be connected to the SeaTalk bus at any point. No independ ent connection to the 12V power supply is necessary as the instruments receive power from the Autopilot course computer. 2. 2 Transducer Selection The type of speed transducer used is dependent on the hull material.

These instructions, together with the following notes, should be read thoroughly before attempting to install the transducer. ` Sing For accurate speed and depth readings, the transducers should be sited within the shaded clear flow areas. Cabling 1 . No&Avoid fluorescent lights, engines, radio transmitting equipment etc. Also, keep the transducer cable clear of bilges and secure at regular intervals. To lock the connectors, push and rotate the ring onthetransducer cable connector towards the instrument connector. 1 Sal 2 Flanning power 3Displxementpower The transducers should also: l l be ahead of the propellers (10% W. L. length minimum) be at least 15Omm (6in) away from the keel (ideally ahead of the keel if a sailing yacht) be as near as possible the centreline of the vessel be clear of otherthroughhull fittings or projections have sufficient clearance inside the hull to fit the nut have 1OOmm (4in) of headroom to allow for withdrawal (depth transducer) be within 10" of vertical, fore, aft and athwartships. l l l l l ST50 Plus Tridata and Repeater Operation and Installation Handbook Chapter 3: Fault Finding and Maintenance Chapter 3: Fault Finding and Maintenance 3. 1 Fault Finding All Autohelm products are, prior to packing and shipping, subjected to comprehensive test and quality assurance programmes. However, if a fault arises with the ST50 Plus Tridata, the following table will help to identify the probable cause and provide the most likely cure. Return unit for repair. , Instrument displays `CODE SET No speed or temperature information. The `Code Lock' feature Enter correct code has been set. Normal reading will return when clear of disturbed water. No speed information. SeaTalk cabling problem. Failure of a group of SeaTalk instruments in SeaTalk cabling/connector chain. Count-up timer Wth the timer legend displayed, momentarily press RESET to start the timer. 10 minute countdown timer Wti timer legend displayed, press RESET for 1 second to access the 10 minute timer. 5 minute countdown timer TIMER With timer legend displayed, press RESET for 1 second to access the 10 minute timer and then press RESET again for 1 second to access the 5 minute timer. Although the display has been frozen the timer continues to count in the background. To return to the `live' timer display, press the RESET key once again.

This is a simple operation that can be carried out automatically over a measured distance or by manually entering a calibration factor. * Automatic Calibration Automatic calibration should be carried out when tidal flow is at a minimum. Locate an easily identified, marked and measured distance on a chart and enter this distance into the instrument (4). [. . . ]
