1 Introduction


SAFETY NOTICE: This manual contains important safety information. An understanding of this information is critical to the safe operation of your equipment. Please ensure that you read the warning notices before using the equipment.

GENERATOR DUTY CYCLE LIMIT

NOTE: THE FOLLOWING SECTION CONTAINS IMPORTANT INFORMATION. PLEASE READ AND UNDERSTAND THIS MATERIAL BEFORE CONTINUING.

Internal X-ray generator components will heat up during normal use of the generator. This is similar to X-ray tube heating during normal generator operation. The amount of heat produced is proportional to the product of kV, mA, and time. Modern X-ray generators are designed to operate with the majority of X-ray tubes over their rated power ranges. They are designed for operating duty cycles consistent with practical patient examination routines that allow for reasonable cooling intervals between X-ray exposures. This X-ray generator has internal duty cycle monitoring to warn of excessive heat build-up. If the generator calculates that the next exposure will exceed the rated generator duty cycle limit, a warning message “GEN DUTY WARNING” will be displayed. Further exposures are inhibited at this point, and the generator must be allowed to cool sufficiently such that this message is no longer displayed. The generator also monitors the X-ray tube’s thermal switch, and will inhibit exposures when the tube reaches its thermal limit. It is the responsibility of the installer to implement and verify this interlock.

DAILY X-RAY TUBE WARM-UP PROCEDURE

CAUTION: THE FOLLOWING PROCEDURE PRODUCES X-RAYS. OBSERVE ALL SAFETY PRECAUTIONS TO PROTECT PERSONNEL.

Use this procedure when the generator is first turned on for the day, or when it has not been used for several hours. This procedure provides for exposures at medium power before the tube is used at maximum mA or kV values. This will reduce the possibility of damaging the anode and high voltage components. No test setup is required.

For maximum stability and reliability, use the following techniques at start up: Select the following: • Large focal spot. • 80 kV. • Normal 50/60 Hz anode rotation.

For a 300 kHU to a 400 kHU tube, use approximately 200 mAs per exposure. For a 200 kHU to 300 kHU tube use approximately 150 mAs per exposure. • Depending on the X-ray tube power rating, select either 100 mA or 200 mA. • Make one (1) to three (3) exposures (depending on tube loading) at 30-second intervals.


SAFETY AND SPECIFICATIONS 2 Keep this operator’s manual with the equipment at all times, and periodically review the operating and safety instructions.

2 Safety and Specifications


X-ray radiation exposure may be damaging to health, with some effects being cumulative and extending over periods of many months or even years. X-ray operators should avoid any exposure to the primary beam and take protective measures to safeguard against scatter radiation. Scatter radiation is caused by any object in the path of the primary beam and may be of equal or less intensity than the primary beam that exposes the film. No practical design can incorporate complete protection for operators or service personnel who do not take adequate safety precautions. Only authorized and properly trained service and operating personnel should be allowed to work with this X-ray generator equipment. The appropriate personnel must be made aware of the inherent dangers associated with the servicing of high voltage equipment and the danger of excessive exposure to X-ray radiation during system operation. • Operators should be trained on the use of the equipment within the facility. They should have the knowledge

in radiology, and the skills, attitude, and judgment to safely and effectively operate the equipment.

• Operators are trained on the use of the X-ray generator by the installer of the X-ray generator. The operator’s manual may be used as a training aid.

• Wear protective clothing. Protective aprons with an equivalent of a minimum of 1/64” (0.35 mm) of lead are recommended.

• To protect the patient against radiation, always use radiation protection accessories in addition to devices which are fitted to the X-ray equipment.

• Keep as large a distance as possible away from the object being exposed and the X-ray tube assembly.

• Never operate this X-ray equipment in areas where there is a risk of explosion. Detergents and disinfectants, including those used on patients, may create explosive mixtures of gases. Please observe the relevant regulations.

• The operator console, or anything electrically connected to it, must never be used within 6 ft (1.8 m) of the patient environment.

NOTE 1 These guidelines may not apply all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. NOTE 2 It is essential that the actual shielding effectiveness and filter attenuation of the shielded location be verified to assure that they meet the minimum specification. a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and

land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the VZW2556 series of X-ray generators is used exceeds the applicable RF compliance level above, the X-ray generator should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the X-ray generator.



ELECTROMAGNETIC COMPATIBILITY (EMC) In accordance with the intended use, some models of this series of X-ray generators comply with the European Council Directive concerning Medical Devices. The CE marking affixed to compliant products signifies this. One of the harmonized standards of this Directive defines the permitted levels of electromagnetic emission from this equipment and its required immunity from the electromagnetic emissions of other devices. It is not possible, however, to exclude with absolute certainty the possibility that other high frequency electronic equipment, which is fully compliant to the EMC regulations, will not adversely affect the operation of this generator. If the other equipment has a comparatively high level of transmission power and is in close proximity to the generator, these EMC concerns (the risk of interference) may be more pronounced. It is therefore recommended that the operation of equipment of this type such as mobile telephones, cordless microphones and other similar mobile radio equipment be restricted from the vicinity of this X-ray generator.

DAP - DOSE AREA PRODUCT (OPTIONAL) The DAP function is only available if the optional DAP device is installed in the X-ray system, and if the DAP function has been enabled in programming. DAP Overview

• The DAP device requires a brief “settling” period after the generator is switched on.

The console will display the start-up screen during the DAP settling period. If the DAP does not stabilize within the normal settling time, the console will display the message DAP NOT READY, and will then proceed to the normal operating mode without the DAP display. If this happens, it indicates that the DAP did not stabilize in the normal time. You may wish to switch the generator off and then on again in an attempt to let the DAP stabilize. If the DAP is still not ready after a second attempt, you may choose to proceed without DAP and then contact your service representative.

• The DAP display is reset to zero when the generator is switched off, and then on

again.

Note: A reading of 0mGycm2 indicates that the DAP display has been reset at power-on or manually reset as described later in this section, and that no exposures have been taken since it was reset.

Note: Always check local regulations to determine how frequently the DAP device must be tested. The procedure to test the DAP follows later in this section.

DAP Display • Before proceeding with initial dose-area product measurements, ensure that the DAP

display is 0mGycm2. The DAP display may be manually reset to zero as described in DAP Reset / Test / Print, following.

• The DAP measures and displays cumulative dose-area product. • The maximum reading on the DAP display is 9999999. An error message will be

presented when this limit is reached.

3 Console Controls


DAP Reset / Test / Print The DAP display may be reset to zero, a manual DAP functional test may be performed when desired, and a label may be printed with the DAP and patient information as described below.

1. Press the MENU button when DAP is displayed at the top center of the LCD screen at the main APR menu. This will present the DAP reset / test / print menu. • Press RESET to reset the DAP display to zero. The display will reset, and the

console will return to the main APR menu.

• Press TEST to test the DAP. The message “DAP TEST: …OK” will be presented if the DAP has passed its test. The console will return to the main APR menu.

• Press PRINT to print the DAP label. Printing…..will briefly be displayed at the

bottom of the screen while data is being sent to the printer. The printer will print the date and time near the top of the label, and the accumulated Dose-Area Product (mGycm2) near the middle of the label. This information is retrieved from the generator at the time the label is printed. Several headings are printed on the labels; the corresponding information may be written in the adjacent spaces using indelible ink:

NAME: Enter the patient’s name. M / F: Check (Male or Female). BORN: Date of Birth. Use the format shown (d / m / y). I.D. #: Enter the patient’s and / or operator’s identification number. TECH: Enter techniques as appropriate for the record.

• Press the MENU button to exit when finished.

NOTE: THE X-RAY GENERATOR MUST BE CONFIGURED FOR THE SPECIFIC PRINTER BY THE INSTALLER OR SERVICE ENGINEER (SEIKO INSTRUMENTS DPU-414 OR SLP-200 PRINTER). THE GENERATOR WILL BE COMPATIBLE ONLY WITH THE SELECTED PRINTER, THEREFORE ONLY THAT PRINTER MODEL MUST BE USED IN THIS INSTALLATION.

NOTE: THE PAPER OR LABELS USED IN THE PRINTER MUST MEET ALL APPLICABLE REGULATIONS. MEDICAL GRADE PAPER OR LABELS, APPROVED FOR MEDICAL RECORDS, MUST NORMALLY BE USED.

Refer to the printer manual for the printer operating instructions, paper feeding, printer troubleshooting, and related information. During the console start-up routine, after the generator has been switched on, the paper in the printer is automatically positioned by the RESET PRINTER function

2. Press the APR EDITOR button to toggle between ENABLED and DISABLED. Set the APR EDITOR to ENABLED.

For reference, DISABLED does not allow editing and then saving the changed APR technique(s). ENABLED allows the operator to change the default APR techniques, and then save the changes. The APR will then default to the newly saved techniques.

The generator stores the last APR editor setting (ENABLED and DISABLED) prior to being switched OFF. If the APR editor was previously ENABLED, APR changes may subsequently be made and then saved in normal operating mode without the need to manually set the APR editor to ENABLED. To disable this feature, the APR editor must be set to DISABLED.

3. Return to normal operation by pressing EXIT SETUP.

4. The following menu is displayed. This is a typical menu, actual anatomical views may have been reprogrammed, and the screen may differ slightly depending on generator model.



TUBE1 0%HU 1:00

*APR TABLES* SKULL UPPER EXTREMITY THORAX LOWER EXTREMITY ABDOMEN G.I. PELVIS SPINE 2 mAs

kVp: 70 mA: 100 ms: 20

5. Perform the APR technique change as outlined below. 6. Select the desired APR menu to be edited; for example SKULL. 7. Select the desired APR view to edit, for example SKULL AP/PA, table Bucky image

receptor. 8. Select the patient size to edit within that view, for example medium. All techniques with the exception of kV will be common to all patient sizes. The

common techniques for all patient sizes within that view should be programmed first, then the desired kV for the selected patient size. After these techniques are saved per the remainder of this section, kV values may be programmed if desired for the other patient sizes in the same APR view.

9. The default selections are shown on the console, for example: 70 kV, 100 mA, 20 ms, technique = mA/ms, large focus. 10. Change the technique to the desired value(s). Parameters that may be edited are: kV,

mA/mAs, time (ms), technique select (AEC / mAs / mA/ms), focus, image receptor, film screen, plus density and field selection in AEC mode.

The APR view being edited will be highlighted with a rectangular outline as soon as any parameter is changed within that view. Also the word SAVE will appear in the display window below the MENU button.

11. Continue making all desired APR changes within that view.

12. When finished, press the MENU button. This is the first step necessary to save the changes. This also allows the option of canceling the changes in the next step.

13. If you do not wish to save the changes, select EXIT (BACK button) to abort the SAVE function. To save the changes, select SAVE (FORWARD button). The message SAVING DATA... will briefly appear.

14. Press the MENU button to return to the main APR screen.



15. You may now make changes to other APR techniques if desired by repeating steps 6 to 14.

16. It is suggested that the APR editor be set to DISABLED as described earlier in this section, in order to avoid unintended APR changes in the future.

PROGRAMMING CM THICKNESS 1. Follow steps 1 to 3 of the previous section (APR EDITOR). 2. Select the desired APR to edit. 3. Select a CM thickness (mAs) or CM thickness (AEC) mode. Select the desired image

receptor, film screen, focal spot, and AEC fields (if applicable) for the selected anatomical view.

4. The AUX 1 button is used for CM thickness programming. In programming mode (with the APR EDITOR set to ENABLED), pressing AUX 1 scrolls through CM START → CM STEP → CM as required to program these parameters.

CM START The minimum CM for the selected technique (CM START range is 1 to 14). To program, refer to step 5.

CM STEP The step size used to establish the CM vs kVp and mAs curve. The CM STEP range is 1 to 5. To program, refer to step 5.

CM The steps on the CM vs kV and mAs curve. To program, refer to step 5.

5. (a) Determine the minimum and maximum thickness in cm for the selected anatomical

view. Thickness outside of this range cannot be selected later in normal operating mode, therefore these dimensions should be chosen carefully.

(b) Determine the cm step size by the following formula: CM Step Size = 8

Maximum thickness (cm) - Minimum thickness (cm)

The calculated step size must be rounded up to the nearest integer, i.e. 1.66 rounds up to a step size of 2.

(c) Select CM START, then enter the minimum thickness determined in step (a).

(d) Select CM STEP, then enter the cm step size calculated in step (b), maximum step size = 5.

(e) Select CM. Press the CM - and + buttons to confirm that the minimum and maximum thickness limits are acceptable. Repeat the above steps if necessary to optimize the minimum and maximum thickness limits. Set CM to minimum thickness before attempting to toggle back to CM START, or else an error message GOTO 1st CM will be presented.



(f) Press CM - to select the minimum thickness. Set the kV and mAs or kV and backup mAs as appropriate for the selected thickness. (In CM thickness (mAs) mode, kV and mAs may be programmed; in CM thickness (AEC) mode, kV and backup mAs may be programmed).

Refer to Programming the mAs / backup mAs, below for the recommended procedure to set this parameter.

(g) Press CM + to select the next thickness step. Set the kVp and mAs / backup mAs for that thickness as per 5 (f). Nine (9) thickness steps are available, with the step size as previously set. The desired kV and mAs / backup mAs may be set for each of those 9 thickness steps. In the normal operating mode, the thickness steps will be 1 cm, regardless of the step size set in APR edit mode. The console will interpolate between the step sizes set up in APR edit mode to determine the correct kV and mAs / backup mAs for each 1 cm thickness step in normal operating mode.

(h) Repeat 5 (g) for the remaining CM steps.

6. When finished editing the APR, press the MENU button. This is the first step necessary to save the changes. This also allows the option of canceling the changes in the next step.

7. If you do not wish to save the changes, select EXIT (BACK button) to abort the SAVE function. To save the changes, select SAVE (FORWARD button). The message SAVING DATA... will briefly appear.

8. Repeat this procedure to edit other anatomical views.

9. Set the APR EDITOR to DISABLED to return to normal operating mode and prevent inadvertent programming changes.



Programming the mAs / backup mAs 1. When programming the mAs (for CM-thickness, mAs mode), or the backup mAs (for CM-

thickness, AEC mode), use the proper mAs (that will produce the correct non-AEC exposure) for each CM thickness step. This will ensure proper CM-thickness programming:

• In CM-thickness (mAs mode), the correct mAs will be assigned to each CM thickness step.

• In CM-thickness (AEC mode), the backup mAs will be nominally two times the programmed mAs, i.e. if 11 mAs is programmed for a certain CM thickness, the backup mAs will be nominally 22 mAs. This “doubling” of the programmed mAs to arrive at the backup mAs is done automatically by the generator when in CM-thickness, AEC mode.

2. The mAs values that are entered during CM-thickness programming are saved in memory after performing the SAVE function as described above.

• If you are in CM-thickness (AEC mode), and the CM - or + buttons are pressed to review the programmed mAs values, the mAs display will update to show the “two times” backup mAs.

• If you are in CM-thickness (AEC mode), and then select CM-thickness (mAs mode) via the technique selector button, the “two times” backup mAs value will be displayed for that CM thickness. Press the CM - or + buttons to update the display and use the normal mAs, not the doubled backup mAs that was carried forward.

• If you are in CM-thickness (mAs mode), and then select CM-thickness (AEC mode) via the technique selector button, the normal mAs value will be displayed for that CM thickness. Press the CM - or + buttons to update the display and use the “two times” backup mAs, not the normal mAs that was carried forward.

MAKING CHANGES TO THE APR TEXT The anatomical sections and views as displayed in the APR window may be altered to suit your requirements, but you will need to contact your service representative to have this done. Use copies of the worksheet on the next page to record your desired changes. One sheet should be used per APR view; the master copy should be photocopied as many times as necessary to record the required changes.

GENERATOR EXPOSURE 6 TABLES

Table 1 following shows the nominal mAs resulting from preselected ms and mA values. This table also shows the range and interrelation of these loading factors. For example, if 20 mAs is selected at 200 mA, it can be seen that the exposure time will be approximately 100 ms. This is determined by reading down the 200 mA column to 20 mAs; then by reading the nominal exposure time 100 ms as shown at the left side of the table, along the 20 mAs row. An extra copy of this table is provided on pages 61 to 70 that may be photocopied as required, or removed from this manual and placed in a suitable location as per local requirements.

MAINTENANCE SCHEDULE 7 This section is organized into two parts. The first part of this section details tests by which the operator can verify that the AEC circuits are functioning, and that there are no apparent defects in the console or associated equipment. These tests should be done monthly as a minimum, or more frequently if required by local regulations.

CAUTION: THE AEC VERIFICATION PROCEDURE REQUIRES THE PRODUCTION OF X-RAYS. OBSERVE CORRECT OPERATING PROCEDURES, AND TAKE APPROPRIATE PRECAUTIONS AGAINST X-RADIATION.

The second part of this section is the recommended maintenance schedule for your generator.

WARNING: REFER ALL SERVICING TO APPROPRIATE SERVICE PERSONNEL WHO ARE TRAINED TO SERVICE THIS EQUIPMENT AND WHO ARE FAMILIAR WITH THE POTENTIAL HAZARDS ASSOCIATED WITH THIS EQUIPMENT.

NOTE: MAINTENANCE SCHEDULE FREQUENCY MAY BE DETERMINED BY CERTAIN REGULATORY REQUIREMENTS OF THE COUNTRY OR STATE IN WHICH THE INSTALLATION IS LOCATED. ALWAYS CHECK THE LOCAL CODES AND REGULATIONS WHEN DETERMINING A MAINTENANCE SCHEDULE.

7 Maintenance Schedule


AEC FUNCTIONAL CHECK The following procedure may be used to verify that the AEC circuits are functioning on generators equipped with AEC (automatic exposure control). 1. Switch the generator ON, and select an appropriate radiographic image receptor. 2. Align the X-ray tube and the selected image receptor such that the central ray is directly

over the center field of the AEC pickup device. Set the focal spot to film plane distance to 40 in. (1 m).

3. Select AEC mode of operation. Select center field, large focus.

MINIMUM EXPOSURE TIME: 4. With no object in the radiation field, adjust the collimator or beam limiting device to project

a 10 in. X 10 in. (24 cm X 24 cm) field at the image receptor. 5. Select 80 kVp, 100 mA, and a backup mAs of 50 if it is operator selectable. If this is not

operator selectable, the default AEC backup settings must be used. Refer to the note at the end of this page to determine the AEC backup mode that has been programmed.

6. Make an exposure and verify that the POST mAs reading is ≤ 2 mAs.

MAXIMUM EXPOSURE TIME: 7. Close the collimator or beam limiting device completely. Place a folded lead apron over

the image receptor. 8. Select 60 kVp, 100 mA, and a backup mAs of 50 if it is operator selectable. If this is not

operator selectable, the default backup settings must be used. Refer to the note at the end of this page to determine the AEC backup mode that has been programmed.

9. Make an exposure and verify that the error message AEC DEVICE ERR, AEC BUT ERROR or AEC BU MAS ERR is indicated in the APR display window after the exposure has terminated. This confirms that the exposure has continued until it was terminated by the AEC backup circuits in the generator.

NOTE: The AEC backup mode is installer programmable. Three modes are available, FIXED, MAS, and MS. Only the MAS mode allows the operator to set the backup mAs for an AEC exposure. FIXED: The generator will determine the maximum AEC backup time, not to exceed preset AEC backup mAs/ms values or system limits. The characters AEC will be displayed in the time window of the LED display during AEC operation. MAS: Allows the operator to adjust the AEC backup mAs, not to exceed preset AEC backup mAs/ms values or system limits. The mAs value will be displayed in the time window of the LED display during AEC operation. MS: Allows the operator to adjust the AEC backup ms, not to exceed preset AEC backup mAs/ms values or system limits. The ms value will be displayed in the time window of the LED display during AEC operation.

Maintenance Schedule 7


CONSOLE AND MISCELLANEOUS GENERATOR CHECKS The user must routinely check the X-ray equipment for apparent defects or damage. Report any apparent defects or irregular operation of any equipment to service personnel immediately, and discontinue use of the suspected faulty equipment until repairs are made. Continuing operation with faulty equipment may present various safety hazards, including risk of increased radiation. 1. Check all visual displays (warning and status lights, technique displays and indicators,

etc) for normal operation. 2. Check all audible indicators (speakers, beepers, etc) for normal operation, and check that

the loudness settings are adequate for the environment. 3. Check all interconnect cables and connectors for damage.



MAINTENANCE ACTIVITIES IN THE TABLE BELOW ARE TO BE PERFORMED BY AUTHORIZED SERVICE PERSONNEL ONLY. HOWEVER THE OWNER OR OPERATOR OF THE EQUIPMENT MUST SCHEDULE THE SUGGESTED MAINTENANCE ACTIVITY WHEN REQUIRED BY CONTACTING THEIR LOCAL SERVICE AGENCY.

Maintenance Frequency

Description of Preventative Maintenance

Every 6 Months AND whenever a related certifiable X-ray component is replaced:

1. Clean and re-grease all HV connections using vapor proof compound.

2. Check that all HV connections are tight. 3. Clean the control console and main cabinet as needed.

REFER TO NEXT PAGE, CLEANING, BEFORE PROCEEDING.

4. Ensure that there are no obstructions blocking the ventilation holes or louvers on the generator cabinet.

5. Perform the X-ray tube auto calibration routine. 6. Verify the calibration of the generator. 7. Perform any additional tests required by laws governing

this installation. Every 12 months: 1. Examine the following for any visible damage and replace

any damaged components:

• The exterior of the control console, including the membrane switch assembly.

• The cable between the control console and the generator main cabinet.

• The hand switch (if used) and the cable connecting this to the console.

2. Open the generator cabinet and examine the unit for any

visible damage: missing or loose ground connections, oil leaks, damaged cables etc.

Every 3 years Replace the cooling fan in the generator main cabinet. Every 5 years: Replace the batteries on the console board in the control

console and the on the generator control board in the main cabinet.

Maintenance Schedule 7


CLEANING • To clean the console surfaces (without disinfecting) use soap and water. This should be

applied using a lint-free cloth as described below. • If console surfaces need to be disinfected, use Actichlor or equivalent with a Hypochlorite

concentration of 3 to 5%. ∗ Dilute the disinfectant 50/50 with water. ∗ Spray or dampen a lint-free cloth with the diluted disinfectant. The cloth must be damp

only, not wet. ∗ Gently wipe the console surfaces with the damp cloth.

• Never use any corrosive, solvent or abrasive detergents or polishes. • Ensure that no water or other liquid can enter any equipment. This precaution prevents

short circuits and corrosion forming on components. • Disinfection by spraying is not recommended because the disinfectant may enter the X-ray

equipment. • Methods of disinfection used must conform to legal regulations and guidelines regarding

disinfection and explosion protection. • If disinfectants which form explosive mixtures of gases are used in the room, these gases

must have dissipated before switching on the equipment again. • If room disinfection is done with an atomizer, it is recommended that the equipment be

switched OFF, allowed to cool down and covered with a plastic sheet. When the disinfectant mist has subsided, the plastic sheet may be removed and the equipment be disinfected by wiping.
