The reader
This manual is intended to be used by a trained maintenance technician or engineer,
with experience of electronic and digital circuitry, computers and electromechanical
design. The level of information is based on Simrad’s maintenance philosophy: The
onboard technical personnel shall, with the help of the documentation and the system’s
built-in test functions, be able to identify malfunctions, locate the fault, and replace
major parts, modules and components on the “Line Replaceable Unit” (LRU) level.
He/she will however not attempt to repair the LRUs.

1.1 Overview
This is the instruction manual for the EA 600 single beam
hydrographic echo sounder system.
The chapters Hardware installation and Transducer installation
contains information about how to install the system, while the
chapters GPT maintenance, Replacement procedures and Spare
parts contains maintenance information.
All cables are described in the chapter Cable layout.
The manual also defines the equipment responsibility, and
provides instructions for unpacking and storage. This is found in
the appendices.
Note The installation instructions given in this document must be
adhered to. Failure to do so may render the guarantee void.
No special tools are generally required to perform installation,
removal and replacement of modules and parts. When special
tools are required, these are listed in the installation procedure.
The manual contains detailed descriptions of each of the units in
the system. Each circuit board and mechanical assembly is
described. The manual includes procedures for disassembly and
reassembly of the replaceable items.
This manual also presents drawings required to install the EA
600 hydrographic echo sounder system.
Note Detailed vessel specific mechanical drawings for the installation
must be provided by the customer, or any shipyard contracted to
perform the installation. Kongsberg Maritime AS may, on
special order, supply these drawings. Drawings must be
approved by the appropriate vessel certification authority prior
to installation of the system.

1.2 Maintenance philosophy
Kongsberg Maritime AS defines three levels for maintenance:
Organizational - You will only perform limited preventive and
corrective maintenance on the system. There is no need for
technical education or training, and no need for any instruments.
Typical tasks are exterior cleaning, or changing fuses.
Intermediate - You will perform overall preventive and
corrective maintenance on the system. It is recommended that
you are an educated engineer with experience from
computerized design and mechanical systems. It is further
expected that you can use standard electronic instruments, such
as an oscilloscope. You should be trained by Kongsberg
Maritime to perform maintenance on the system. Typical tasks
may include troubleshooting, testing and circuit board
replacement.
Depot - You will perform detailed maintenance on the system
and on the circuit boards and modules. You must be an educated
engineer with experience of computerized design and
mechanical systems. It is further expected that you can use
standard electronic instruments, such as an oscilloscope. You
should be trained by Kongsberg Maritime to perform
maintenance on the system. Typical tasks are circuit board
repair.
Note This manual is prepared for the intermediate level.
This manual does not describe the maintenance of the computer
and the peripheral devices (printers, plotters and sensors). For
information about these items, refer to the applicable
manufacturer’s documentation.

857-164688 / E
1.3 General safety rules
The system operates on 115 and/or 230 VAC, 50/60 Hz.
<km[email protected]>
The following safety precautions must be followed at all times
during installation and maintenance work:
•Always switch off all power before installation or
maintenance. Use the main circuit breaker, and label the
breaker with a warning sign that informs others that
maintenance or installation work is being carried out on the
system.
•For safety reasons during troubleshooting on the equipment
with power ON, two persons should always be present.
•Whenever maintenance is carried out, it is essential that a
first aid kit is available, and that the maintenance personnel
are familiar with the first aid instructions for electrical shock.
•The various parts of the system are heavy. Make sure that the
appropriate tools and certified lifting equipment are
available, and that the personnel are trained in installation
and maintenance work.

1.4 System overview
Key facts
The EA 600 is a single or multi frequency echo sounder
designed for the professional hydrography community. It can
operate with maximum four frequency channels simultanously.
•The EA 600 system is flexible and easy to configure due to
the modular design.
•The EA 600 is available in several versions. The standard EA
600 system uses a Hydrographic Operator Station (HOS)
(combined display and computer). A system using a desktop
computer is optionally available. For IP55 protection of the
transceiver unit(s) a dedicated steel cabinet may be supplied.
•Echo sounders ranging from relatively low-cost single beam
to large multi-frequency systems can be realised.
•Menus and dialogue boxes are operated with a standard
computer mouse and keyboard.
•Large colour liquid crystal displays (LCD) are used. A
standard computer mouse may be used.
•The EA 600 uses the Microsoft Windows®display interface.
Operation is to a large extent self-explanatory. Getting started
is easy if you are familiar with standard Microsoft
Windows®programs.
•A store/replay function reduces the need for echogram
printout on paper. The unprocessed transducer signal is
recorded on the internal harddisk. During replay, this signal
is injected into the EA 600 processing software as if it
arrived directly from the transceiver.
Main units
The standard EA 600 hydrographic echo sounder consists of one
or more transducers, a General Purpose Transceiver (GPT) and
a Hydrographic Operator Station (HOS). When required for
enhanced protection, the GPT unit(s) may be installed in a
dedicated steel cabinet.
•Transducers are available at frequencies ranging from 12 to
710 kHz.
•The General Purpose Transceiver (GPT) contains transmitter
and receiver electronics. It can be configured for single beam
operation. The receivers are designed for low noise, and they
can handle input signals spanning a very large instantaneous
dynamic amplitude range of 160 dB. All targets are correctly
measured and displayed. Output transmit power per
frequency channel is maximum 2 kW per channel.

Introduction
5
857-164688 / E
•A twisted pair Ethernet cable connects the General Purpose
Transceiver (GPT) with the computer. The distance between
the computer and the GPT can be extended up to 100 meters.
•If more than one transceiver is used, a small ethernet HUB or
switch is used to connect the General Purpose Transceivers to
the computer.
•Most of the echo sounder functions are implemented in
software. The bottom detection algorithm is implemented
solely in software with separate computation for each
frequency channel.
•Interfaces are provided for depth telegram output as well as
navigation data, temperature sensor and motion sensor inputs.
An external push button may be connected for manually start
and stop of the survey lines.
•An external push button may be added for manual control of
the event triggering.
•Socket interface is included. To run the EA 600 software and
other software (for example survey- or classification
software) on the same computer, this socket interface is
required for data transmission between the software
packages.
