Fitting transducer
The ST60+ Depth instrument is supplied, with a through-hull depth transducer.
The depth transducer is supplied with detailed instructions for installation and
maintenance. Before attempting to install the depth 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+ Depth instrument. The manner in which you run the
cable will depend on the locations of the transducer and instrument.
Observing the following guidelines, run the transducer cable to the ST60+ Depth
instrument:
• 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 interference.
• Although the transducer cable is fitted with spade connectors for direct con-
nection to the rear of the instrument, it may be necessary to remove these to
facilitate installation, e.g. if the cable has to be routed through narrow aper-
tures. Extra spade connectors are provided, to replace any that are removed
when running the cable. 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.
