Transducer
The cylindrical transducer allows the sonar beam to provide a full 360 degrees coverage of
the water volume. The horizontal beam can be tilted from –10 to +60 degrees.
The transducer converts the electric energy generated by the transmitter circuitry to physical
vibrations. These vibrations alter the water pressure, and create an acoustic pulse that is
sent into the water. The acoustic signal is transmitted as a beam. The duration of the
acoustic pulse, as well as its frequency and shape, are controlled by the system software.
The direction and opening angle of the beam is controlled by the transmitter circuitry and
the physical properties of the transducer. After the transmission, the transducer works as
a "microphone". It converts the water pressure created by the acoustic echoes to electric
energy. These weak echo signals are sent to the amplifiers in the receiver circuitry.
Note
The transducer is covered with a thick red or black protective coating made of a special
plastic type. The protective coating is a vital part of the transducer. It is very important
that neither this coating nor the internal parts of the transducer are damaged during the
handling, installation or cleaning. Any holes and/or scratches in the transducer surface will
allow water to penetrate the transducer. If a leak occurs, the transducer must be replaced.
The transducer is mounted at the bottom end of the hull unit’s transducer shaft. This allows
the transducer to be lowered into the water for operational use, and retracted for protection

when the SY50 system is turned off. By lowering the transducer into the water, you may
also be able to reduce the noise created by the laminar flow of water along the hull.
Rules for transducer handling
A transducer must always be handled as a delicate instrument. Incorrect actions may damage
the transducer beyond repair. A physical blow to the transducer face may easily damage one
or more elements. Observe these transducer handling rules:
• Do not activate the transducer when it is out of the water.
• Do not handle the transducer roughly. Avoid impacts.
• Do not expose the transducer to direct sunlight or excessive heat.
• Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean
the transducer.
• Do not damage the outer protective skin of the transducer.
• Do not step on the transducer cable.
• Do not damage the transducer cable. Avoid exposure to sharp objects.

General safety rules
Safety is important. The safety precautions must be followed at all times during installation
and maintenance work.
WARNING
The SY50 system operates on 24 VDC and/or 230 VAC (50/60 Hz). These voltages are
potentially lethal! You must never work alone on high-voltage equipment!
This equipment must be installed, adjusted, and serviced only by qualified electrical
maintenance personnel familiar with the construction and operation of the equipment
and the hazards involved. Failure to observe this precaution could result in bodily
injury.
Personnel requirements
All personnel must be trained in relevant installation and maintenance work.
Personal protection
Installation personnel must wear suitable work clothes. The work clothes must not
contain sufficient static to ignite. Always wear a hard hat and suitable protective
footwear while handling heavy objects.
Power and ground
You must always turn off all power before installation or maintenance work on the
SY50 system. Use the main circuit breaker, and label the breaker with a warning sign
that informs others that maintenance or installation work is in progress on the system.
For safety reasons, two persons must always be present during troubleshooting with
power turned ON.
All SY50 system units must be properly grounded.
First aid
Read and understand the applicable first aid instructions related to electric shock.
Whenever installation or maintenance work is in progress, it is essential that a first
aid kit is available. All personnel must be familiar with the first aid instructions for
electrical shock and other personal injuries.
Weight
The various parts of the system may be heavy. Make sure that the appropriate tools
and certified lifting equipment are available. Always wear a hard hat and suitable
protective footwear while handling heavy objects.
12
110-0003888/A
Replacing the transducer
Cables
Each electric cable must be handled carefully. This is important to avoid damage to
the cable. This is also important to avoid electric shock in the event that the cable is
unintentionally connected to a power source.
Cabinets
Do not open racks or cabinet doors while sailing in rough seas. Doors and/or cabinet
parts may suddenly swing open and cause damage or injury.
Personnel qualifications
Corrective maintenance and hardware modifications can only done by personnel that are
certified and authorized.
As a minimum, the following certified personnel must be available:
• Service engineers
If necessary, assistance must be provided by:
• Dockyard workers
• Ship electricians
This publication is intended for qualified service engineers and technicians. You must
understand the general principles of maritime electronic equipment. You must also be
familiar with computer hardware, signal processing, interface technology and traditional
troubleshooting on electronic and mechanical products. We also expect that you have some
experience with echo sounder and/or sonar operation.
Note
Personnel who work with service, replacement of parts and/or corrective maintenance must
be authorized by the Kongsberg Maritime support organization.
Rules for transducer handling
To secure long life and accurate results, the transducer must be handled correctly.
A transducer must always be handled as a delicate instrument. Incorrect actions may damage
the transducer beyond repair. A physical blow to the transducer face may easily damage one
or more elements. Observe these transducer handling rules:
• Do not activate the transducer when it is out of the water.
110-0003888/A
13
Simrad SY50 Transducer replacement
• Do not handle the transducer roughly. Avoid impacts.
• Do not expose the transducer to direct sunlight or excessive heat.
• Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean
the transducer.
• Do not damage the outer protective skin of the transducer.
• Do not step on the transducer cable.
• Do not damage the transducer cable. Avoid exposure to sharp objects.
Cleaning the transducer face
Whenever opportunity arise, typically when the vessel is dry-docked, the transducer face
must be cleaned for shells and other marine growth.
• Be careful so that you do not accidentally make cuts or inflict other physical damage to
the transducer face.
• Remove biological fouling carefully using a plastic brush, a suitable synthetic detergent
and fresh water. Biological material which is strongly rooted in the substrate can be
removed carefully with a piece of wood or plastic.
• Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean
the transducer.
Painting the transducer face
The transducer has not been designed with any protection against biological fouling.
Anti-fouling paint may therefore be applied to the transducer face. To minimize the negative
acoustical effects the layer of anti-fouling paint must be as thin as possible.
Note
The anti-fouling paint will reduce the acoustical performance of the transducer. The
surface roughness of the transducer substrate and the thickness of the paint may also
influence the performance. Kongsberg Maritime cannot be held responsible for any negative
consequences of the anti-fouling paint.
Because some paint types may be aggressive to the polyurethane in the transducer, consult
our list of approved paints. The list can also be found on our website.
Observe the relevant instructions and safety information provided by the paint manufacturer.
