Transducer Handling And Maintenance; Rules For Transducer Handling - Simrad ES70 - INSTALLATION REV A Installation Manual

Steel conduits qualities and shielding
The steel conduit must be unbroken and watertight from the transducer to above the
water line. From there, the cable can be pulled further, or a junction box can be installed
to facilitate further connections. Note that the steel conduit must act as a continuous
electrical screen all the way.
Steel conduit dimensions:
• minimum 35 mm inner diameter
• minimum 6 mm wall thickness (4.5 mm if galvanised)
More that one transducer cable?
If two or more transducers are installed close to each other it is possible to pull their
cables in the same steel conduit, provided the conduit diameter is increased accordingly.
However, for easy replacement it is recommended that each transducer has its own
steel conduit.

Transducer handling and maintenance

You MUST observe the following rules for handling, maintenance and painting.

Rules for transducer handling

Note
Do not lift the transducer by the cable.
Do not expose the transducer to direct sunlight.
Do not expose the transducer to excessive heat.
Transport protection
Some transducers are delivered with a cover plate on the face for protection during
transport. Let this plate stay on as long as possible, but do not forget to remove it before
the vessel goes into the sea.
Painting the transducer face
An anti-fouling paint may be applied to the transducer face. Because some paint types
may be aggressive to the polyurethane in the transducer face, please consult Simrad's list
of approved paints. See Approved anti-fouling paints for transducers on page 144.
Cleaning the transducer face
Whenever opportunity arise, for example when the vessel is dry docked, the transducer
face may be cleaned for shells and other marine fouling. Be careful not to make cuts in
the transducer face. Use a piece of soft wood or a very fine grade emery paper.
