READ THIS FIRST

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.

1.0 General Safety

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/composite- toe shoes.

State: RELEASE - Document is released and under formal Change	See the GEHC Myworkshop System to determine the status of this

1.3Laser Exposure

•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.

1.4Shutter Indicator

•This symbol is used to indicate an open-shutter condition in accordance 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.

1.5Cautions, 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.

1.5.1Caution Statements

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

1.5.2 Warning Statements

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

1.5.3 Note Statements

Note: This symbol turns the reader's attention to important information which may otherwise be overlooked.

1.6Safety Concerns

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.

DO NOT touch live components on the DC power supply - when the cover is off of the supply some components (such as the heat sinks) are at line voltage and present a shock hazard

1.7Scatter 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.
