Using This Manual

A person who will be performing service work on the DPX-NT / MD+ should use this
manual in the following manner:

Read the Safety and Overview Chapters to familiarize yourself with the scanner
as a whole and with the genera lfunction of the circuit boards.

Chapter 3 should be understood completely as it explains the Diagnostics
Software (built in – requires a password for access).

The Chapter 4 and Chapter 5 contain common procedures and troubleshooting
information and can be read as needed, but are good sources of information.

When a problem arises, Chapter 4 should be referenced. Check the table of
contents for Chapter 4 to see if the problem being experienced is described. If
so, refer to the appropriate page. If not, try to generalize the problem (e.g. the
Detector is repeatedly running into the front of the scanner and reversing and
then running back into the front of the scanner. This is a mechanical problem in
general, specifically with Transverse Mechanics, check that subsection of
Chapter 4 for the subsystem experiencing the fault.

This manual commonly references other Sections and pages of the manual as
needed, so often procedures in the Chapter 5 and the Appendix are referred to
as ways to solve problems described in Chapter 4.

DPX-NT/MD+ Service Manual (Rev. 3 - 2010)

Page 17 of 141

x DO NOT attempt to service the DPX-NT / MD+ without first reading

this manual.

x DO NOT attempt any repairs without prior instructions from

authorized LUNAR personnel.

x In order to maintain electrical safety and electromagnetic

compatibility, the Lunar DPX-NT / MD+ is only to be connected to a
computer, printer, and peripherals that meet IEC requirements for
safety, such as IEC 950/ EN 60950 - “Safety of information
technology equipment, including electrical business equipment” and
IEC 601-1-2 - “Medical electrical equipment”, Part 1: General
requirements for safety, 2. Collateral Standard: Electromagnetic
compatibility - Requirements and tests.

x Ionizing Radiation: Exposure: When power is applied, this

equipment may generate ionizing radiation. Take precautions that no
part of the body passes through the x-ray beam when the equipment
is energized. Avoid scatter radiation during warm-up and testing by
maintaining a safe distance from the x-ray beam. See the Safety and
Specification manual for equipment appropriate distance and other
precautions regarding ionizing radiation. All operators must be
properly trained regarding ionizing radiation and take adequate steps
to protect against injury.

x Electric Shock: This equipment contains high voltages. When the

tabletop/panels/ shrouds are removed, visually confirm that power
cord is unplugged and remains unplugged until power is required to
complete the procedure. When servicing while energized, take
precautions to prevent electric shock.

x Moving Parts and Pinch Points: Avoid moving parts and pinch

points (e.g. belt/pulley, arm/back rail, green wheels/rail).

x Sharp Edges: Take precautions to prevent injury from contact with

component edges (e.g. OMI/OMD wheel, arm slot cover).

x Hot Surfaces: Keep hands clear or allow components to cool before

servicing. (e.g. stepper motors, hard drives, power supplies and
microprocessors).

x Heavy Lifting: Obtain help lifting or moving any object weighing over

EHS limits. Ask for assistance when maneuvering awkward objects
(e.g. tabletop).

x Laser Radiation: Do not stare into the laser beam at any time. The

reflection from the tabletop or shutter/collimator assembly is sufficient
to determine if the laser is on.

x Follow appropriate Lockout/Tagout procedures as described in

MyLearning training course GEMS-EHS-LOTOAth.

x Wear appropriate PPE (Personal Protective Equipment) while

servicing the equipment, e.g. eye protection and steel-toe/composite­toe shoes.

This label states that
grounding reliability can only be maintained when using a
“Hospital Grade” or “Hospital Only” receptacle. It is only found
on systems delivered in the United States.

Note: When replacing a certified component (x-ray controller, x-ray

tube head, collimator or high voltage power supply(s)) also
install the duplicate certified component label (supplied with
the repalcement certified component) on the foot end panel of
the scanner. The label for the new part should be palced
directly over the laber for the part it is replacing.

Refer to DXSE3001 DPX-NT / MD+ Label Replacement
Procedure (Chapter 5Appendix I - this manual) for specific
instructions.

1.2 Emergency Stop Button

• The Emergency Stop Button is located on the front of the scan arm of the
DPX-NT / MD+ scanner (see Figure 1-1). When pressed, power is
removed from the X-ray tube head, the laser, and the shutter is closed.
Power is also removed from the scan arm motors, allowing the operator/
patient to push the scan arm out of the way.

1.3 Laser Exposure

DPX-NT/MD+ Service Manual (Rev. 3 - 2010)

Page 23 of 141

• The DPX-NT / MD+ is equipped with a Class II Laser device. This laser is
used for patient positioning. A Class II rating indicates a low power visible
laser that is not normally hazardous to eyesight but has the potential to
be hazardous if viewed directly for an extended period of time. Because
of this potential hazard, DO NOT stare directly into the beam while the
laser is in operation, and DO NOT allow the beam to shine directly into
the patients' eyes. No specific eye protection is required with a Class II
laser.

• A amber laser-on indicator, located on the front of the scan arm, is lit
when the laser is on. The program activates the laser during positioning
for an image acquisition. The program then turns off the laser when you
begin the scan. The emergency stop button will turn off the laser.

• There is a caution label (Figure 1.2) on the scan arm near the Display
Panel.

with the safety standards established by the International
Electrotechnical Commission (IEC).

Figure 1-5. Source (x-rays) off - Shutter closed (green)

Figure 1-6. Source (x-rays) on - Shutter open (yellow)

• This symbol appears near the yellow X-ray shutter-open indicator light.
The X-ray shutter-open indicator light is located on the Display Panel on
the scan arm near the front.

Note: When the x-ray on / shutter open symbol appears in literature

associated with the DPX-NT / MD+ scanner, it will be used to
indicate that the procedure being described results in an open­shutter condition. During these times personnel should
exercise caution to avoid excessive exposure to the X-rays.

1.5 Cautions, Warnings, and Notes

• This manual contains warning and caution statements wherever
appropriate for your safety. The warnings and cautions used throughout
the manual are based on the safety standards established by the
International Electrotechnical Commission (IEC). In addition, the manual
uses notes to attract the reader's attention to important information.

1.5.1 Caution Statements

A caution statement reflects a condition
that, if not avoided, could cause
equipment or property damage.

Note: This symbol turns the reader's attention to important

information which may otherwise be overlooked.

1.6 Safety Concerns

A warning statement reflects a potentially
hazardous condition that, if not avoided, could
result in serious injury.

Because the DPX-NT / MD+ Densitometer
contains moving parts, there are places on the
scanner where there is a danger of pinching.
Operators should be aware of these pinch

points to avoid injury to the patient or
themselves. Labels applied at the LUNAR factory indicate the
location of the pinch points. The pinch points and their labels
are shown in the figure 1-7.

DPX-NT/MD+ Service Manual (Rev. 3 - 2010)

the cover is off of the supply some components (such as the
heat sinks) are at line voltage and present a shock hazard

1.7 Scatter Radiation

• There is some scatter radiation from the DPX-NT / MD+ when it is
running. Figure 1-8 shows the radiation dosages while the scanner is
running at 1.50 mA at certain distances.

• These dosages are relatively insignificant as the allowed yearly dosage
for a person working with radiation emitting equipment is 5000 mRem.
Radiation however should be avoided when possible.
