1–2 IMPORT ANT CONVENTIONS

1–2–1 Conventions Used in Book Model Designations. There are three basic models of the LOGIQ 700. These models are referenced throughout

this manual as V1, V2, and V3. The V1 was the initial model. The V2 model resulted when Electromagnetic Compatibility (EMC) provisions were added. The V3 model retains the EMC provisions, but uses 16–channel Time Delay boards (TDs) rather than 8–channel TDs.

Icons. Pictures, or icons, are used wherever they will reinforce the printed message. The icons, labels and conventions used on the product and in the service information are described in this chapter.

Safety Precaution Messages. Various levels of safety precaution messages may be found on the equipment and in the service information. The different levels of concern are identified by a flag word that precedes the precautionary message. Known or potential hazards are labeled in one of three ways:

LOGIQ 700 BASIC SERVICE MANUAL

Direction 46–030402

DANGER

Danger is used to indicate the presence of a hazard that will cause severe personal injury or death if the instructions are ignored.

WARNING

Warning is used to indicate the presence of a hazard that can cause severe personal injury and property damage if instructions are ignored.

CAUTION

Caution is used to indicate the presence of a hazard that will or can cause minor personal injury and property damage if instructions are ignored.

Notes. Notes are used to provide important information about an item or a procedure. Be sure to read the notes:

the information contained in a note can often save you time or effort. Diagram Conventions. Conventions used in the diagrams within the service manuals include:

Circuit blocks on circuit cards that reside in the Front End (FE) card cage are shaded in dark gray.

Circuit blocks on circuit cards that reside in the Back End (BE) card cage are shaded in light gray.

Circuit blocks or parts that are optional are shaded with angled stripes.

A3–P2–A32 Designators are used to describe physical location and component types. In the

example at the left: A3 is the slot, P2 is the connector, A32 is the pin.

MC_ALM_40P0–P Signal names usually indicate their source and destination. The signal name

shown originates on the MC (master controller) and is provided to the ALM (Acoustic Line Memory). When a signal is delivered to a part, and the part does not currently use that signal, the signal’s name is listed but a line is drawn through the name.

CAUTION

Should you need to replace a rear wheel, follow the removal and installation procedures given in Section 5. The rear wheel assembly has two springs. If the wrong screws are removed, the springs can cause the assembly to disintegrate with explosive force.

When the unit is raised for a repair or moved along any incline, use extreme caution since it may become unstable and tip over if positioned at angles greater than 10_.

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.

The LOGIQt 700 weighs approximately 300 kg (660 lbs). 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. ALWAYS:

Be sure the pathway is clear. Use slow, careful motions. Use two people when moving on inclines or lifting more than 23 kg (50 lb).

Note

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

Secure the unit in an upright position. DO NOT use the Control Panel as an anchor point. Place the probes in their carrying case. Eject any magneto optical drive (MOD) disk from the MOD.

CAUTION

The control panel can be elevated by pressing the actuator button that pulls down the top bracket of the gas spring that places the linear bearing under pressure in the upward direction. Take care when you activate this gas spring. You could be hit by the panel or hurt your hand by upward movement of the linear bearing after the panel is removed and the spring pressure is released.

DANGER

Only qualified service personnel should remove any covers or panels. Electrical hazards exists at several points inside including the AC distribution assembly, two backplanes, three power supplies, isolation transformer, and circuit boards. Become thoroughly familiar with all hazardous voltages and high current levels to avoid accidental contact.

W ARNING

High current power supplies even at 5 volts can cause welding of leads, jewelry or other conductive materials.

Safe Practices. There are additional rules to protect the service person, operator and patient from exposure to

dangerous electric power.

Only connect the unit to a properly grounded, hospital grade power outlet. Do not use a three to two prong adapter. This defeats safety grounding.

Do NOT use a 20 Amp to 15 Amp adapter on 120 Vac machines that require a 20 Amp cord.

To prevent dangerous leakage currents, do NOT use an extension cord or non–listed peripherals that have not been certified.

When ESD protection is needed (replacing boards and drives), the service person should be trained in the electrical hazards of this unit, wear the ESD wrist strap and leave the unit plugged to maintain ground.

CAUTION

WARNING

Ultrasound transducers can be easily damaged by improper handling. Failure to follow these precautions can result in serious injury and equipment damage.

Probes. A powered probe could injure someone if its internal parts contact a person through a conductive solution

or a break in the isolating material. Therefore:

DO NOT immerse a probe into any liquid beyond the level indicated by the immersion level diagram shown on its care card and the operators manual.

DO NOT immerse a probe into any solution containing acetone, alcohol, bleach, detergent, iodine, or hydrogen peroxide because these can break down its isolation. Avoid gels containing mineral oil or lanolin.

DO NOT drop probes or subject them to other types of mechanical shock or impact. Degraded performance or damage such as cracks or chips in the housing may result.

DO NOT kink, tightly coil, or apply excessive force on the probe cable. Insulation failure may result.

Inspect the probe before and after each use for damage or degradation to the housing, strain relief, lens, and seal. A thorough inspection should be conducted during the cleaning process.

Perform electrical current leakage tests on a routine basis to check for cracks or other small defects.

1–4–1 Electromagnetic Interference (EMI)

ElectroMagnetic Interference (EMI) describes the energy that is emitted or conducted from an operating electronic system. This energy can be in many forms. It can be radio frequency (RF) waves, magnetic fields, electrical potential variations, electrical current leakage.

1–4–2 Electromagnetic Compatibility (EMC)

ElectroMagnetic Compatibility (EMC) describes an electronic system that curbs the electromagnetic influence between electronic systems. This means it minimizes how much electromagnetic energy it emits or conducts into the surroundings so that this energy is not dangerous nor distorts its own or another system’s operation. It means it minimizes the electromagnetic interference from itself or other electronic systems.

Only use power and signal wiring provided or specified by GE Medical Systems. Never use an adaptor to connect a power source plug. Do not change cable length or material. Use of cables not properly shielded and grounded may result in the equipment causing or responding to radio frequency interference in violation of the European Union Medical Device Directive (CE mark) and FCC regulations.

LOGIQ 700 BASIC SERVICE MANUAL

Direction 46–030402

Use the peripherals specified by GE Medical Systems. Do NOT allow the monitor or peripheral cables to lie across the top of the Front End cage.

Locate the unit as far as possible from other electronic equipment.

Install the unit, peripherals, and replacement parts only as detailed in the Preinstallation Checks, Installation Chapter, Assembly Chapter, Renewal Parts Chapter, and the Peripheral Install manual. Use CE certified parts.

Reinstall all hardware before returning the unit to clinical use.

If unit is connected to a network, use only CE marked components for hubs, transceivers, peripherals, modems. Make sure transceiver is LOCKed into place on bulkhead (Ethernet) AUI connector.

It is recommend that coax wire is used to connect ethernet to hub. FIBER OPTIC IS BEST for problem sites but expensive and requires an optical HUB.

1–4–4 Electrostatic Discharge (ESD) Prevention

LOGIQ 700 BASIC SERVICE MANUAL

Direction 46–030402

The circuit boards and disk drives for this system contain densely populated electronic components which are expensive and electrically sensitive. An electrostatic discharge (ESD) between 100 to 1000 V may damage a component. This is substantially less than the 3000 V discharge needed to feel any static. The ESD may cause an immediate failure, or it may weaken components to produce future, intermittent problems.

Proper Handling. Always use the ESD strap. Put the board or drive inside an anti–static bag or approved container before it is handled by a non–grounded person, moved from the grounded (ESD safe) area, or stored. Always place the board or drive top side up on a flat surface when it is unmounted. Never handle the part outside its anti–static container unless the surrounding surfaces and you are grounded. Discharge the outside of the container before transferring the part.

TABLE 1–3

RULES FOR PREVENTING OR LESSENING ESD DAMAGE

ESD rule Details Turn power OFF Turn power OFF before you touch, insert or remove parts having electronic

components.

Use wrist strap Unless you are working near a live 30 V or more circuit, ground your wrist to the

specially designed ground plug on the unit before you touch any parts. This includes

connecting cables to a drive, board, device, or bulkhead. Test your strap while wearing it with a specially designed meter. If it fails, it may

be due to dry skin; apply lotion to your wrist and test again. Throw away any strap that is more than three months old.

Don’t let anything but your grounded hand touch the electronic FRU

Use proper handling

Treat failed parts the same as good

Do not let your sleeve, tie, pen, Styrofoam cup, plastic manual binder or clothing touch the circuit board or disk drive. Wearing cotton clothes and shoes with rubber like soles may lessen how much ESD you generate walking across the room. Working in a room where relative humidity is under 20% can generate electrostatic voltages of 7000 to 35,000 Volts. However it only takes 100 V to destroy an EEPROM.

Handle circuit boards, disk drives, or any electronic part as little as possible. Place them on an anti–static workbench pad or in a static dissipative bag that you have grounded. Do not stack them. LOGIQ anti–static container. Pink, blue, or clear poly bags do NOT give protection from external sources of ESD. If you have an anti–static box, you can use the box as a static free work surface once you ground it.

You don’t want to add to the expense, complication and future unreliability of a part by allowing it to be repeatedly zapped.

700 boards should be stored in an

EMI rule Details

Be aware of RF sources

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.

Ground the unit Poor grounding is the most likely reason a unit will have noisy images. Check

grounding of the power cord and power outlet.

Replace all screws, RF gaskets, covers, cores

After you finish repairing or updating the system, replace all covers and tighten all screws. On a V2/V3 unit any cable with an external connection requires a magnet wrap at each end. Tightly wrap the mesh around the I and Q connectors on the SS. Install the shields over the front of both card cages. Loose or missing covers or RF gaskets allow radio frequencies to interfere with the ultrasound signals.

Replace broken RF gaskets

Do not place labels where RF gaskets touch

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.

harnesses and peripherals

Take care with cellular phones

In a V2 or V3 unit, the interconnect cables are grounded and require EMI magnets 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; a signal greater than 3 V/m

could cause image artifacts. Use a regular phone within 5 m (16 ft) of the unit.

No power line filters

Properly dress peripheral cables

Filters placed between the power main and unit may cause problems; do not use one unless authorized by GE Engineering.

For a 120 V ac V1 unit, inrush current is 150 to 175 A for up to four ms. For all other power configurations, including V1 units with the Soft Start design, inrush will be less than 70 A.

2–4–3 Site Circuit Breaker

CAUTION

POWER OUTAGE MAY OCCUR The LOGIQt 700 requires a dedicated single branch circuit. To avoid circuit overload and possible loss of critical care equipment, make sure you DO NOT have any other equipment operating on the same circuit.

It is recommended that the branch circuit breaker for the machine be readily accessible. It should have at least a five times the rated current tolerance.

2–4–4 Site Power Outlets

A dedicated AC power outlet must be within reach of the unit without extension cords. Other outlets adequate for the external peripherals, medical and test equipment needed to support this unit must also be present within 1 m (3.2 ft) of the unit. Electrical installation must meet all current local, state, and national electrical codes.

2–4–5 Unit Power Plug

If the unit arrives without a power plug, or the wrong plug, the installation engineer must supply what is locally required.

2–4–6 Power Stability Requirements

Monitor the site’s line voltage for a week before installation. The voltage should be stable, remaining within 10 % of the unit’s rated value. In addition, line frequency should fall between 47 and 63 Hertz.

Power transients must be less than 25% over nominal peak voltage for less than 1 ms for any type of transient. This includes line frequency, synchronous, asynchronous, or aperiodic transients.

Note

If the site’s power line voltage does not meet the requirements outlined, it is suggested that a ferro resonant Uninterruptable Power Supply (UPS) be provided. A tap switching line conditioner is not recommended because the switching transients can exceed the limits specified for the LOGIQ 700.

Direction 46–030402

DANGER

CAUTION

When using any test instrument that is capable of opening the AC ground line (i.e., meter’s ground switch is OPEN), don’t touch the unit!

Two people should unpack the unit because of its weight. Two people are required whenever a part weighing 22 kg (50 lb) or more must be lifted.

If the unit is very cold or hot, do not turn on its power until it has had a chance to acclimate to its operating environment. The equipment could be damaged if powered on when it is colder than 15_C (59_F) or hotter than 30_C (86_F).

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.

Do not wear the ESD wrist strap when you work on live circuits and more than 30 V peak is present.

Do not use a 20 Amp to 15 Amp adapter on the 120 Vac unit’s power cord. This unit requires a dedicated 20 A circuit and can have a 15A plug if the on board peripherals do not cause the unit to draw more than 14.0 amps.

3–6–6 Correcting Leakage Current Problems

Note

No outlet tester can detect the condition where the neutral (grounded supply) wire and the ground (protective earth) wire are reversed. If later tests indicate high leakage currents, this should be suspected as a possible cause. An electrician should visually inspect the outlet wiring.

If a leakage current test fails, use Table to help isolate and correct the problem. First locate the name of the failed test in the Test Failed column. Then try the check/correct actions in the same row, one at a time until the problem is resolved.

If the problem cannot be resolved using the actions described in Table, continue isolation by removing the probes, external peripherals, then the on board ones, one at a time while monitoring the leakage current measurement. If the situation cannot be corrected, submit a GEWINS TYPE C CQA Report to document a regulatory/noncompliance issue. Remove unit from operation.

Check the ground on the power cord and plug for continuity. Ensure cord is not broken, frayed, or intermittent. Replace any defective part.

Tighten all grounds. Ensure star washers are under all ground studs. Inspect wiring for bad crimps, poor connections, or damage. Test the designated outlet; verify the outlet is grounded. If not, notify

the user or owner to correct any deviations, and, as a work around, check and temporarily use any other outlet that is within reach and properly grounded.

Test the probe in another XDIF connector. If you suspect a bad connector, test probe leakage to that particular XDIF connector with a different probe.

If excessive leakage current is slot dependent, inspect that XDIF connector for bent pins, poor connections, and ground continuity.

If the problem stays with the probe, replace the probe.

Tighten all grounds. Inspect wiring for bad crimps, poor connections, or damage. Measure the ground continuity of the external peripheral power cord. It

should be less than 0.15 ohms. If the power cord is detachable, the limit is 0.20 ohms.

Test the AC outlet used by this peripheral; verify it is grounded. Notify the user or owner to correct any deviations. As a work around, check the other outlets to see if they could be used instead.

3–7 TRANSPORTING THE UNIT

Follow these guidelines to assure your premium ultrasound unit operates correctly and safely after it has been moved to another room or site.

Before moving, eject any MOD disk to prevent damaging the drive.

Store all loose parts, like gel and optical disks, in the unit pockets.

Before moving to a new site, remove and pack transducers in their original cases or in soft cloth or foam to prevent damage.

Disconnect external devices from the back panel.

Unplug the power cord from the AC outlet and wrap it counter clockwise (CCW) in its slot. DO NOT TUCK PLUG UNDER THE AREA WHERE IT IS ATTACHED T O THE CONSOLE. This could distort/loosen the connection.

One adult can usually move the unit along a level surface for short distances. Otherwise, two people or more should move the machine. Avoid inclines steeper than ten degrees and bumps higher than one inch. Do not let the unit strike walls or door frames. Limit the speed of movement to a slow, careful walk.

LOGIQ 700 BASIC SERVICE MANUAL

Direction 46–030402

Know how the foot brake on this unit works and be ready to use it. It is located near the floor on the front side. Set it whenever you stop.

If you will be moving your unit to other sites, save and reuse the original packaging. GE Medical Systems representatives or their assignees should perform the move. A specially designed van for this unit should also be used.

The van should have good shocks and a door large enough for the unit with its monitor and any on board peripherals to clear.

If a lift is used, be sure it can handle at least 360 kg (800 lbs) although a 400 kg capacity would be safer. Don’t remain on the lift with the unit.

Load the unit into the van very carefully. Keep it over its center of gravity. Secure the unit with straps, keeping it still and upright yet not damaging the control panel. DO NOT lay the unit down ! DO NOT attempt to hold it in place by hand!

Prevent vibration damage by driving cautiously. Avoid unpaved roads, excessive speeds, and erratic stops or starts.

Repeat the Installation Checklist at the new site.

CAUTION

Never move the unit with a disk in the MOD because the drive actuator will not be locked and the MOD could break. Avoid mechanical ejection (method 3.d below) which leaves the actuator unlocked and the MOD susceptible to damage if moved. If forced to use method 3.d, reboot the system, insert and eject a known good diskette using one of the other methods.

3 . The are a number of methods to eject a disk from the MOD. Ejection is automatic in some cases. Manual

ejection methods, listed in preferred order of use, are: a . Use the softkey choice under Archive Menu –or– click Image Presets up then click the left softkey switch

up for ARCHIVE, then toggle the switch under EJECT MOD.

b . Press EJECT button on the MOD while system is ON. c . Hold EJECT button while the system is booting. d . Insert the end of a paper clip into the hole next to the EJECT button while system power is OFF.

4–2–3 Archiving and Loading Presets

Note

Always save presets before any software reload. This action is necessary to ensure that the presets locaded after the software reload are as up–to–date as possible.

With system software versions R6 and later, all user presets except changes to English language defaults for the OB comments, can be saved on an MOD disk for reloading on the system. Only seconds are needed to save or load Presets in this manner.

Presets can be saved on the same MOD disk as images. But presets and images are best kept on separate MOD disks because the Archive Menu lists the images but not the presets stored on an MOD disk.

1 . To archive Presets on an MOD disk:

a . Obtain a blank disk or a disk to be recycled. Check the disk to insure that there is no loose hardware or

labels. Set the slide switch to write enable (open the hole) on the MOD disk. Then insert the MOD disk into the MOD.

b . Click the Image Presets toggle switch up. The Modify softmenu appears. c . Click the ARCHIVE softkey up. The Archive Presets softmenu appears.

5–2 LOGIQ 700 DESCRIPTION

5–2–1 Major Components

The LOGIQ 700 has two card cages, a monitor, a hard drive, a magneto optical drive (MOD), and an XDIF assembly that is used to mount the probes. (See Illustration 5–1.) The circuit boards housed in the cages plus the operator control panel form four functional subsystems: the Kernel, Beamformer, Mid Processor, and Scan Converter.

In addition to the components shown, the unit has a blower or fan assembly to circulate air for cooling and three power supplies, a transformer, circuit breakers, and an outlet strip that makeup a power generation/distribution subsystem. These components are housed in the lower rear of the unit.

5–2–2 Ultrasound Data Path

The ultrasound data path begins with the operator’s request translated to commands and scan sequences (vector parameters) delivered at the right moment to the appropriate circuit boards. Strong radio frequency (RF) beams are transmitted and weak ones are received between the beamformer, probe and patient. The Scan Sequencer board (SS) of the Kernel is the interface between the Front End cards and Back End. The SS forwards the CPU and scan controls to the Beamformer which returns the digital baseband I and Q ultrasound data to the SS. The SS then delivers this data to all three boards of the Mid Processor. Here they are processed according to their scan acquisition mode. The data is accumulated, synced and output to the Scan Converter which prepares the vector data for video display to the monitor, printers, recorders, and camera. The audio signals are processed in the Kernel by the PIA board. All control of the system is managed by the Motorola MVME167 card on the Back End board called the Master Controller.

5–3 ACOUSTIC OUTPUT

LOGIQ 700 BASIC SERVICE MANUAL

Direction 46–030402

CAUTION

POTENTIAL TISSUE DAMAGE Although the system limits maximum acoustic power magnitude, the operator must be careful with the duration. The AO percentage is a relative indicator of potential bioeffect. When examining sensitive tissue or when the percentage approaches 100, the user should attempt to minimize exposure time. Refer to Appendix A in the Operator Manual for additional information concerning potential bioeffects and means for minimizing exposure.

5–3–1 Acoustic Output (AO) Definition

The monitor displays an AO percentage which is related to the potential for producing mechanical or thermal bioeffects (cavitation or heating) in the patient. The percentage is of maximum output possible. The purpose of the Acoustic Output display is to keep the operator aware at all times of the energy being generated. As the operator changes settings that affect acoustic output, the potential for bioeffect is reflected in the percentage that is computed and displayed in real time. An increase in the displayed percentage means an increased potential for bioeffect.

5–3–2 AO Factors

The power of the transmitted ultrasound beam depends on the AO level (1–5), probe, depth, frequency, and scan mode. Software calculates values for pulse amplitude, number of cycles per transmission, and pulse repetition interval (PRI) based on these variables. The default level and hardcopy OFF can be preset.

5–3–3 Mechanical Index (MI)

MI is represented on the display and is related to cavitational bioeffects. As acoustic waves pass through tissue, they cause it to expand and contract. This expansion may cause gas bubbles to form. This effect is called cavitation; it is not known whether this is a health risk.

5–3–4 Thermal Index (TI)

TI is added to the display when another scan mode is added to the B image. TI indicates the potential for heat generation within tissue. Tissue heating is more of a concern when the acoustic beam is stationary, so the TI is likely to increase when Doppler or M modes are selected. Three different TIs may be used depending on the type of tissue being examined:

Soft Tissue Thermal Index (TIS) indicates the potential to generate heat within soft tissues.

Bone Thermal Index (TIB) indicates the potential to generate heat at the beam focus when focusing on or near bone that is adjacent to very sensitive tissue. This index is intended as a thermal indicator for second and third trimester fetal examination or transfontanelle neonatal cephalic exams.

Cranial Bone Thermal Index (TIC) indicates the potential to generate heat in the near–field when the beam passes through bone at the surface as with adult or pediatric cranial applications.

5–4–1 Front End (FE) Cards

The portion of the system called the FE is basically the beamformer subsystem. The beamformer creates and transmits sonographic waves and then receives the echoes. Most of the circuit boards that comprise the beamformer subsystem are housed in the FE card cage. These circuit cards use multi layer boards that are 340 mm high and 400 mm deep and are accessed from the left side of the unit as you face it. See Illustrations 5–5 or 5–6 and Table 5–5 for more details about individual card cards.

These boards contain CMOS. Being in circuit does not protect them. Wear a tested ESD strap whenever your hand comes near the parts that contain electronic components. Remove power if you will be disconnecting parts.

Practice good ESD prevention when you disconnect or attach items to the bulkhead. A ground strap around your wrist, clipped to the ground stud on the back, should prevent large electrical potential discharges into the BE backplane which could damage circuit boards and therefore system performance. An alternate method would be to touch the frame behind the air filter before and while making video, audio, SCSI, ethernet, and serial connections.

board.

assures system EMC, cooling and image quality.

The FE backplane (FEBP) and the diode board as well as the HV Cap Assembly and HV filter board are accessed from the right side of unit as you face it. The remainder of the FE consists of the Transducer Interface Board (XDIF) and probes which are mounted on the front of the unit. See Table 5–6 for more details about these individual card cards.

5–4–2 Back End (BE) Cards

The BE includes three subsystems: Scan Converter, Mid Processor , and Kernel. The circuit cards that make up these subsystems are housed in the BE card cage.

The BE circuit cards also use multi–layer circuit boards. These circuit boards are about 340 mm square in size. The BE circuit cards, including the MC and its on–board Single–Board Computer that controls all data transfers, are accessed from the front of the unit.

Note

Top and bottom center screws on the cage’s filler panel must be installed to keep the cage square and the boards well connected.
