Section 1-3 Safety Considerations

1-3-1 Introduction

The following safety precautions must be observed during all phases of operation, service and repair of this equipment. Failure to comply with these precautions or with specific warnings elsewhere in this manual, violates safety standards of design, manufacture and intended use of the equipment.

CARE FULLY READ ALL THE WARNINGS LISTED BELOW.

1.) Read the LOGIQ™ 180 Operator Manual thoroughly before operating the system and keep at hand

for ready reference.

2.) Although the ultrasound energy transmitted from the LOGIQ™ 180 transducer is within AIUM/

NEMA standards, unnecessary exposure should be avoided. Only trained personnel should operate/service the LOGIQ™ 180.

3.) To avoid electrical shock, use only the supplied power cords and connect them to properly

grounded power Sock et. Do not use a three pin to two pin adapter. This defeats the purpose of safety grounding. System should be operated within the voltage limits.

4.) Probes are fragile, please handle with care. A damaged probe may cause an electrically hazardous

condition when coupled to the human body. A damaged probe will not produce a desirable image. A damaged probe has to be discarded. It cannot be repaired or reused. Do not allow the lens to come into contact with a sharp object or to be knocked against an object.

5.) Do not place liquids on or above the console. If the liquid spills, it may come in to contact with live

parts and can cause an electric shok.This system contains no operator serviceable components. To prevent shock, do not re move any covers or panels. Should problems or malfunctions occur, unplug the power cord. Only qualified Service personnel should service the system. Accidentally coming in contact with the electrical circuits inside the housing could cause serious injury.

6.) Do not use Defibrillators when the LOGIQ™ 180 is operated.

7.) Concerning outside markings, refer to ILLUSTRATION 1-1.

NOTE: This medical equipment is approved, in terms of the prevention of radio wave interference, to

be used in hospitals, clinics and other institutions which are environmentally qualified. The use of this equipment in an inappropriate environment may cause some electronic interference to radios and televisions around the equipment. Proper handling of this equipment is required in order to avoid such trouble according to the operator and service manuals.

1-3-2 Human Safety

Operating personnel must not remove the system covers.

Servicing should be performed by authorized personnel only.

Only personnel who have participated in a LOGIQ™ 180 Training Seminar are authorized to service the equipment.

Chapter 1 Introduction 1 - 7

GE MEDICAL SYSTEMS DIRECTION 2317229, REVISION 3 LOGIQ™ 180 BASIC SERVICE MANUAL

1-3-3 Mechanical Safety

WARNINGWARNING

When the unit is raised for a repair or moved along any incline, use extreme caution since it may become unstable and tip over.

WARNINGWARNING

Ultrasound probes are highly sensitive medical instruments that can easily be damaged by improper handling. Use care when handling and protect from damage when not in use. Do not use a damaged or defective probe. Failure to follow these precautions can result in serious injury and equipment damage.

WARNINGWARNING

CAUTION

NOTE: Special care should be taken when transporting the unit in a vehicle:

Never use a probe that has fallen to the floor. Even if it looks ok, it may be damaged.

The LOGIQ™ 180 weights 70kg or more, depending on installed peripherals, when ready for use. Care must be used when moving it or replacing its parts. Failure to follow the precautions listed below could result in injury, uncontrolled motion and costly damage.

• Secure the unit in an upright position.

• Lock the wheels (brake)

• DO NOT use the Control Panel as an anchor point.

• Place the probes in their carrying case.

1-3-4 Electrical Safety

2-2-3 EMI Limitations

Ultrasound machines are susceptible to Electromagnetic Interference (EMI) from radio frequencies, magnetic fields, and transients in the air or wiring. They also generate EMI. The LOGIQ™ 180 complies with limits as stated on the EMC label. However there is no guarantee that interference will not occur in a particular installation.

Possible EMI sources should be identified before the unit is installed.

Electrical and electronic equipment may produce EMI unintentionally as the result of a defect. These sources include:

• medical lasers,

• scanners,

• cauterizing guns,

• computers,

• monitors,

• fans,

• gel warmers,

• microwave ovens,

• light dimmers

• portable phones.

The presence of a broadcast station or broadcast van may also cause interference.

See Ta bl e 2 -11 for EMI Prevention tips.

2-2-3EMI Limitations (cont’d).

Table 2-11 EMI Prevention/abatement

EMI Rule Details

Be aware of RF sources

Ground the unit

Replace all screws, RF gaskets, covers, cores

Replace broken RF gaskets

Do not place labels where RF gaskets touch metal

Use GE specified harnesses and peripherals

Take care with cellular phones

Properly dress peripheral cables

Keep the unit at least 5 meters or 15 feet away from other EMI sources. Special shielding may be required to eliminate interference problems caused by high frequency, high powered radio or video broadcast signals.

Poor grounding is the most likely reason a unit will have noisy images. Check grounding of the power cord and power outlet.

After you finish repairing or updating the system, replace all covers and tighten all screws. Any cable with an external connection requires a magnet wrap at each end. Install the shield over the front of card cage. Loose or missing covers or RF gaskets allow radio frequencies to interfere with the ultrasound signals.

If more than 20% or a pair of the fingers on an RF gasket are broken, replace the gasket. Do not turn on the unit until any loose metallic part is removed.

Never place a label where RF gaskets meet the unit. Otherwise, the gap created will permit RF leakage. Or, if a label has been found in such a position, move the label.

The interconnect cables are grounded and require ferrite beads and other shielding. Also, cable length, material, and routing are all important; do not change from what is specified.

Cellular phones may transmit a 5 V/m signal; that could cause image artifacts.

Do not allow cables to lie across the top of the card cage or hang out of the peripheral bays. Loop the excess length for peripheral cables inside the peripheral bays. Attach the monitor cables to the frame.

Section 2-3 Facility Needs

2-3-1 Purchaser Responsibility

The work and materials needed to prepare the site is the responsibility of the purchaser. Delay, confusion, and waste of manpower can be avoided by completing pre installation work before delivery. Use the Pre installation checklist to verify that all needed steps have been taken. Purchaser responsibility includes:

• Procuring the materials required.

• Completing the preparations before delivery of the ultrasound system.

• Paying the costs for any alterations and modifications not specifically provided in the sales contract.

NOTE: All electrical installations that are preliminary to the positioning of the equipment at the site

prepared for the equipment must be performed by licensed electrical contractors. Other connections between pieces of electrical equipment, calibrations, and testing must also be performed by qualified personnel. The products involved (and the accompanying electrical installations) are highly sophisticated and special engineering competence is required. All electrical work on these products must comply with the requirements of applicable electrical codes. The purchaser of GE equipment must only utilize qualified personnel to perform electrical servicing on the equipment.

The desire to use a non-listed or customer provided product or to place an approved product further from the system than the interface kit allows presents challenges to the installation team. To avoid delays during installation, such variances should be made known to the individuals or group performing the installation at the earliest possible date (preferable prior to the purchase).

The ultrasound suite must be clean prior to delivery of the machine. Carpet is not recommended should also be investigated before delivery. Dirt, static, and EMI can negatively impact system reliability

To prevent electrical shock, connect the unit to a properly grounded power outlet. Do not use a three to two prong adapter. This defeats safety grounding.

Electric shock hazard. The user is responsible to assure that, when peripherals or accessories are interconnected with the LOGIQ™ 180 , the combination must conform to the requirements of IEC/EN 60601-1-1 standard for safety of electrical medical systems. Leakage current safe limits may be exceeded and serious injury may result if the following precautions are not followed:

1.) All peripheral or accessory devices must be in conformance with their applicable standard for safety. Computer devices must conform to IEC-EN 60950.

2.) The system of interconnected devices must conform to the leakage current requirements for electrical medical equipment if any portion of the system is located within the patient vicinity (within two meters of the patient).

3.) To achieve safe leakage current levels for equipment located within the patient vicinity, it may be necessary to install data or mains isolation or additional protective earth conductors. Devices having individual mains cords should always be connected to separate mains outlets. Multipleoutlet extension boxes should not be used to power the LOGIQ™ 180 and the computer device from a single mains plug.

4.) If safe leakage current levels are not achieved, the all parts of the system must be removed from the patient vicinity before being interconnected. For example, the transfer of the images from the LOGIQ™ 180 to a personal computer which exceeds safe current limits for medical electrical

equipment must be done only if both pieces of equipment are not located in the patient vicinity.

Section 5-4 Functional Subsystems

5-4-1 Front End Board

The Front End generates the strong transmit bursts, transmitted by the probes as ultrasound into the body. It also receives weak ultrasound echoes from blood cells and body structure, amplifies the signals and convert them to a 16 bit digital signal.

The digital representation of the signal is presented to DSC.

5-4-2 DSC Board

DSC (Digital Scan Converter) function is to convert analog data to digital data and stores in AFM (Acoustic Frame Memory), then the Acoustic Frame Memory is transformed to X-Y plane memory (XYM). While doing transformation from Acoustic Frame Memory to X-Y plane memory, it does Quad point interpolation.

This also houses the electronics to display the plane memory data on NTSC or PAL TV monitor.

5-4-3 CPU Board

CPU Board Controls the overall system function including man-machine interface. It also has an Overlay graphics controller which generates Overlay Graphics/Text for the screen. The Overlay data output goes to the DSC Block.

The CPU performs the following functions:

1.) RTC for time and date

2.) DRAM for intermediate data storage

3.) EPROM for program memory

4.) Address Decoder for control signals

5.) Gain Encoder

6.) Overlay Graphics Controller and memory for overlay text data storage and manipulation

7.) TV Sync Generator for generating Sync and blank signal for composite video.

8.) It interfaces with Digital Scan Converter

9.) NV RAM for System Preset Parameters Storage

10.)Flash memory for storing upto 16 images. The CPU also interfaces with the Flash board (Optional Module) which can increase the storage capacity to 112 images.The Back End Processor grabs the data from the Image Port, stores it in a memory, performs scan.

5-4-4 Peripherals

VCR, Black & White Video Graphic Printer and Printer can be connected to the scanner. For more details on recommended peripherals refer Chapter 3.
