Introduction

Organization

Introduction

This manual provides only information most often needed in the field.

Experienced personnel will be able to use accompanying perfor­mance testing, and preventive maintenance checklists.

The manual contains major tab divisions for diagrams, procedures,
adjustments, fault isolation, configuration supplement, Operating
Notes, Service Bulletins, reference, and parts.

ACTIVE DOCUMENT LIST: lists all active documents pertaining to
the Ultramarkr9 HDI Ultrasound System. Listed are active service
bulletins, service manuals, operation manuals, translated operation
manuals and operating notes.

HDI--i

DIAGRAMS: includes diagrams of system/data paths, power dis­tribution, and cabling.

PROCEDURES: contains information on pre-installation require­ments, installation, performance testing, and preventive mainte­nance.

ADJUSTMENTS: procedures for field authorized adjustments,
including adjustment parameters and location diagrams.

FAULT ISOLATION: system self-diagnostics and fault isolation
information organized by PCB. Also includes minimum configuration
information.

CONFIGURATION: hardware and software compatibility information
for specific system configurations.

OPERATING NOTES: contains operating infor-mation not incorpo­rated into the operation manual.

HDI--ii

SERVICE BULLETINS: includes copies of all active service bulle­tins. “Hot Tips” may be added as they are received by the CSR.

REPLACEABLE PARTS: contains illustrated parts listings of parts
commonly replaced in the field.

REFERENCE: for information regarding interconnecting cables and
connectors used in the Ultramark 9 HDI as well as other miscella­neous information. This section is currently empty.

Manual Usage and Update Information

The Table of Contents and List of Effective Pages have been com­bined for this manual. There is no List of Illustrations or List of Tables.
This will facilitate frequent updating of the manual and allow CSRs to
easily determine the effective date of referenced information.

The contents of a manual change package should be inserted as
indicated on the cover sheet attached to the package. Changed or
added pages can be identified by the change date at the bottom of
the affected page. No change date indicates the page is an original

HDI--iii

page. Change bars located in the outside margin of the page denote
the specific part of a page that was changed at that date. A pointing
hand indicates the portion of the figure that has been changed.

Page numbers are divided into three parts. The prefix identifies the
system covered by the manual. The middle portion identifies the sec­tion of the manual. The suffix indicates the actual page number.

Safety and Precautions

This section provides biological, procedural, environmental, electrical
and mechanical safety information.

WARNING statements identify conditions or practices that could
result in personal injury or death.

CAUTION statements identify conditions or practices that could result
in equipment damage.

HDI--iv

Biological Safety

The assessment of the biological effects of diagnostic ultrasound on
humans is not complete. Diagnostic ultrasound procedures should be
used only for valid reasons, for the shortest period of time, and at the
lowest power settings necessary to produce diagnostically accept­able images.

Procedural Safety

W ARNING

Do not service or adjust a system unless another
person capable of rendering first aid is present.

CAUTION

Do not sterilize scanheads with heat, liquid, gas, or
solvents. Do not autoclave or expose to tempera­tures exceeding 50_C(131_F). Permanent damage
may result.

HDI--v

W ARNING

Disconnect power source and scanheads prior to
cleaning.

W ARNING

Inspect the transducer face, housing, and cable
before using the instrument. Do not use damaged
transducers.

W ARNING

Equipment grounding: This equipment is classified
Class I, Type B as defined in IEC Standard 601-1
Safety of Medical Electrical Equipment. Electrical
shock protection is provided by connecting the
instrument chassis to safety ground using the
3-wire power cable provided. This cable must be
connected to a properly grounded receptacle. Do
not defeat the grounding integrity of the equipment.

HDI--vi

W ARNING

Shock hazards exist if the system is not properly
grounded. The system must be plugged into a hos­pital-grade outlet.

W ARNING

Do not replace components with power connected.
Under certain conditions, dangerous voltages may
exist with power removed. Disconnect power and
discharge circuits before touching.

W ARNING

Fuse replacement is to be done by qualified service
personnel only. Avoid electric shock and fire hazard
by using proper fuses.

CAUTION

Verify the system is set to proper power source
voltage and the cart power plug mates with the
power receptacle.

HDI--vii

W ARNING

Additional hazards may be introduced by using
substituted parts or modified instruments.

W ARNING

Using accessories not recommended by ATL may
cause electrical shock or other unsafe conditions.

CAUTION

Verify circuit boards and components are dry
before applying system power.

CAUTION

This equipment contains components which are
electro-static sensitive. Proper static procedures,
protection and equipment must be used prior to
opening and during handling of this equipment.
Failure to use ESD procedures will cause damage
to these components. Such damage to components
is not covered by ATL warranties.

HDI--viii

Environmental Safety

Do not operate a system in the presence of flam­mable gases or anesthetics or in an oxygen
enriched environment (i.e., in an explosive atmo­sphere). An explosion could result.

Mechanical Safety

Use caution when transporting the system over
uneven surfaces, including entry to or exit from ele­vators.

Stacking equipment on the system, other than ATL
specified equipment, can cause it to become
mechanically unstable.

W ARNING

CAUTION

W ARNING

HDI--ix

Do not use esters or ketone solutions to clean
parts. Discoloration (or worse) will result.

System Safety Symbology

Document IEC601-1, International Electrotechnical Commission:
Safety of Medical Electrical Equipment, classifies patient connections
according to whether the outer enclosure is grounded or floating
(non-conducting). The classifications are shown below.

Grounded chassis. Protection against electrical shock is provided by
connection of chassis to the safety ground (IEC601-1 Type B).

Isolated patient connection (IEC 601-1 Type BF).

Isolated patient connection (IEC 601-1 Type CF).

CAUTION

I and O on circuit breaker and power switch represents ON and OFF,
respectively.

HDI--x

!

IPX--1

This symbol identifies safety note. Be sure you understand the func­tion of this control before using it.

Drip-proof hand-held appliance (transducer assembly). This instru­ment may be safely handled with wet hands.

Identifies protective earth ground (located next to ground stud on
the rear panel).

Identifies the point where the system safety ground is fastened to the
chassis.

The following a re internal symbols (for reference only):

Identifies high voltage components operating above 1000 VDC or
1500 VAC.

NOTE:

NOTE:

The block diagrams in this section include PCBs for all
options available for each PCB configuration. Refer to the
following notes as appropriate.

Generates 120 MHz clock on ST CW systems

and on Non--steered CW systems with the

7500--0570 FEC. On newer systems without

ST CW/CW, the 2DAcquisition will not be

installed. In this case, the 120 MHz clock

originates from the 7500--0754 FEC.

3

The MFE1 is not in thesteered CW data path.
It generates static CW/TCD transmit pulses
and is in receive data path for static CW/TCD.
For steered CW, the system uses more thanone
element for TX and RX. Steered CW transmit and
receive signals must be routed thru thebeamformer
to provide summation.

NOTE:

In the following table captions, where there are two slot loca­tions separated by a slash, the slot locations correspond to
the -0588 and -0677 motherboards respectively. Where
there is only one slot location, it corresponds to both mother­boards.
