Fitting transducer
The ST60 Tridata instrument is supplied, with appropriate
Each transducer is supplied with detailed instructions for installation and maintenance. Before attempting to install a transducer, read these instructions and the Site requirements for transducers described in this Chapter.
Once you are satisfied you can meet all the installation requirements, install the transducer in accordance with the accompanying installation instructions.
Running transducer cable
Each transducer type has a 14 m (45 ft) cable fitted with spade terminals for connection to the ST60 Tridata instrument. The manner in which you run the cable will depend on the locations of the transducers and instrument. The following guidelines are provided:
•If the cable has to be fed through the deck, always use a proprietary 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.
•Do not route the cable through bilges.
•Wherever possible, route the cable away from fluorescent lights, engines, radio transmitting equipment, as these may cause interfer- ence.
•The transducer cables are fitted with spade connectors for direct con- nection to the rear of the instrument. However, it may be necessary to remove these to facilitate installation, e.g. if a cable has to be routed through narrow apertures. Extra spade connectors are provided, to replace any that are removed when running transducer cables. When fitting spade connectors, prepare the cable as at (a) in the following illustration, then fold back the wire strands and insert into the spade connector as at (b). Ensure the wire strands do not extend beyond the rear of the spade connector insulation, then crimp the connector to the wire.
