ATTENTION LES APPAREILS À RAYONS X SONT DANGEREUX À LA FOIS POUR LE PATIENT ET POUR LE MANIPULATEUR SI LES MESURES DE PROTECTION NE SONT PAS STRICTEMENT APPLIQUEES Bien que cet appareil soit construit selon les normes de sécurité les plus sévères, la source de rayonnement X représente un danger lorsque le manipulateur est non qualifié ou non averti. Une exposition excessive au rayonnement X entraîne des dommages à l’organisme. Par conséquent, toutes les précautions doivent être prises pour éviter que les personnes non autorisées ou non qualifiées utilisent cet appareil créant ainsi un danger pour les autres et pour elles–mêmes. Avant chaque manipulation, les personnes qualifiées et autorisées à se servir de cet appareil doivent se renseigner sur les mesures de protection établies par la Commission Internationale de la Protection Radiologique, Annales 26 : Recommandations de la Commission Internationale sur la Protection Radiologique et les normes nationales en vigueur.

WARNING X–RAY EQUIPMENT IS DANGEROUS TO BOTH PATIENT AND OPERATOR UNLESS MEASURES OF PROTECTION ARE STRICTLY OBSERVED Though this equipment is built to the highest standards of electrical and mechanical safety, the useful x–ray beam becomes a source of danger in the hands of the unauthorized or unqualified operator. Excessive exposure to x–radiation causes damage to human tissue. Therefore, adequate precautions must be taken to prevent unauthorized or unqualified persons from operating this equipment or exposing themselves or others to its radiation. Before operation, persons qualified and authorized to operate this equipment should be familiar with the Recommendations of the International Commission on Radiological Protection, contained in Annals Number 26 of the ICRP, and with applicable national standards.

ATENCION LOS APARATOS DE RAYOS X SON PELIGROSOS PARA EL PACIENTE Y EL MANIPULADOR CUANDO LAS NORMAS DE PROTECCION NO ESTAN OBSERVADAS Aunque este aparato está construido según las normas de seguridad más estrictas, la radiación X constituye un peligro al ser manipulado por personas no autorizadas o incompetentes. Una exposición excesiva a la radiación X puede causar daños al organismo. Por consiguiente, se deberán tomar todas las precauciones necesarias para evitar que las personas incompetentes o no autorizadas utilicen este aparato, lo que sería un peligro para los demás y para sí mismas. Antes de efectuar las manipulaciones, las personas habilitadas y competentes en el uso de este aparato, deberán informarse sobre las normas de protección fijadas por la Comisión Internacional de la Protección Radiológica, Anales No 26: Recomendaciónes de la Comisión Internacional sobre la Protección Radiológica y normas nacionales.

ACHTUNG RÖNTGENAPPARATE SIND EINE GEFAHR FÜR PATIENTEN SOWIE BEDIENUNGSPERSONAL, WENN DIE GELTENDEN SICHERHEITSVORKEHRUNGEN NICHT GENAU BEACHTET WERDEN Dieser Apparat entspricht in seiner Bauweise strengsten elektrischen und mechanischen Sichereitsnormen, doch in den Händen unbefugter oder unqualifizierter Personen wird er zu einer Gefahrenquelle. Übermäßige Röntgenbestrahlung ist für den menschlichen Organismus schädlich. Deswegen sind hinreichende Vorsichtsmaßnahmen erforderlich, um zu verhindern, daßunbefugte oder unqualifizierte Personen solche Geräte bedienen oder sich selbst und andere Personen deren Bestrahlung aussetzen können. Vor Inbetriebnahme dieses Apparats sollte sich das qualifizierte und befugte Bedienungspersonal mit den geltenden Kriterien für den gefahrlosen Strahleneinsatz durch sorgfältiges Studium des Hefts Nr. 26 der Internationalen Kommission für Strahlenschutz (ICRP) vertraut machen: Empfehlungen der Internationalen Kommission für Strahlenschutz und anderer nationaler Normenbehörden.

CHAPTER 1 – INTRODUCTION SECTION 1 MAINTENANCE TOOLS 1–1

Mammocom Diagnostic assistance is provided by many maintenance tests, accessible from a service terminal connected to generator interface board 400PL2, and using communication software known as “Mammocom”. The use of this software is described in Chapter 2. The diagnostic tests are accessed through a set of menus, called up on the screen of the service terminal as required. These menus are linked in a tree structure. Refer to Illustrations 1–1 to 1–4 for an overview of this structure. Illustrations 1–1 and 1–2 refer to Generator maintenance; Illustrations 1–3 and 1–4 refer to Gantry maintenance.

1–2

Module Disassembly/Reassembly A set of job cards giving instructions for module disassembly/reassembly is provided in Chapter 3.

1–3

Error codes Error codes are given on the DMR console when the system detects any anomaly in operation. Chapter 4 describes and lists these codes (in their “technical code” format). For each code it gives the meaning and, where relevant, recommends which of the Troubleshooting guides (Chapter 5) should be consulted first to trace the error.

1–4

Troubleshooting Guides A set of Troubleshooting Guides (TSG) is provided in Chapter 5. These give recommended procedures for tracing and correcting faults.

SECTION 2 DIAGNOSTIC PROCEDURE 2–1

Power-up problems The full DMR power-up is defined as being the status corresponding to the correct generation of two signals :      and INV_SUPPLY_OK, i.e: D

Level “1” on TP27 on board 400PL2 (     and.

D

Level “1” on TP25 on board 400PL2 (    – (see Diagram 1 in A2).

The service terminal cannot be used for diagnostic assistance until the Senographe DMR is in the state defined above. The various stages of the power-up are shown (along the time axis) in the diagram on page 3/11 of TSG01. 2–2

Problems generating error messages

2–2–1 Function of self-test For most of the tests concerning the generator, the test line is in either the “active” or “inactive” state. The next line, “Self-test”, is in either the “Yes” or “No” state. 1. Configuration    If the responses received by the CPU are not as expected, the CPU board immediately cancels all commands passed to the hardware, even if the user maintains the test command (1st or 2nd). 2. Configuration   

The CPU maintains the commands passed to the hardware for as long as the test is still activated by the user, even if the responses received by the CPU are not as expected. This enables significant values to be measured on the hardware. 2–2–2 Screen facilities For the HT function, hardware values can be measured using two sub-tests : The SCR gate drive test and short circuit inverter test. Other screens display the static status of certain signals (TSG 016 and TSG 019). 2–3

CPU board and interface problems Boards concerned : D

Generator :

400PL3 and 400PL2,

D

Gantry :

800PL3 and 800PL2.

When a Trouble Shooting Guide is used to identify and replace defective boards, the resulting replacement will very rarely concern the two CPU boards. This is due to the simple fact that, if the system is generating error codes and activating various tests, then the CPU boards are probably serviceable.

1–2

GE Medical Systems

Senographe DMR + asm 2252561-100

2–3–1 CPU board diagnostic The two CPU boards (400PL3 and 800PL3) execute, independently, identical internal tests, at each system power-up. When the ON button is pressed, there is a delay of around 2.5s before LED DS1 “TEST OK” lights up and remains on, if the internal test results are correct. If LED DS1 does not light up, replace the CPU boards (the two CPU boards only use the +5V). Note:

The internal tests do not check bus G64.

2–3–2 Error codes generated by Generator CPU board 400PL3 and Generator Interface board 400PL2 together After the internal tests mentioned above have been successfully executed, Generator CPU board 400PL3 runs the INTERFACE GENE test. An incorrect result for this test generates error codes between 004/001 and 004/018 and, if this is the case, it is recommended that the Generator CPU board 400PL3 and the Interface board 400PL2 both be changed. 2–3–3 Error codes generated by Gantry CPU board 800PL3 and Gantry Interface board 800PL2 together Gantry CPU board 800PL3 runs a test similar to that mentioned in 2-3-2, above. An incorrect result for this test generates error codes between 101/001 and 101/008 and, if this is the case, it is recommended that the Gantry CPU board 800PL3 and the Interface board 800PL2 both be changed. Note:

Error codes between 101/001 and 101/008 cannot be displayed if the serial line (two optical fiber cables) is not operating, between the two CPUs. The internal tests mentioned in 2-3-1, above, test all the serial links by looping back to the CPUs. However, this looping back does not include the “optical” link circuits on interface boards 400PL2 and 800PL2.

SECTION 3 USE OF THE BLOCK DIAGRAMS On a test screen, when a software command line or a status line passes through an interface board (400PL2 or 800PL2), the “hardware point” is shown, next to the bus data, on the corresponding block diagram. The TSGs also give the logic level relationships. To locate corresponding signals on the block diagrams and the drawings, the signals shown on the block diagram must be found in the alphabetically sorted list given in the s.m. The “FROM” and “TO” columns specify the drawing pages to be consulted. SECTION 4 SENOGRAPHE DRAWINGS The Senographe drawings were produced using MENTOR software, which also draws the printed circuit layouts. Thus, the drawings contain quite a lot of information not required by the maintenance function. For example, in the 400PL1 drawing, pages 5, 7, 12, 16, 21 and 26 are of no use whatsoever to maintenance. The rule is that points at the same electrical equipotential must be given strictly identical names. A signal which is inverted twice must not be given its initial name as it is no longer the same electrical point. The sign used in the drawings indicates that one electrical point has two different name, and DOES NOT correspond to a physical strap.

Connection Hardware The PC/Senographe connection is made via an RS232 serial connection supported by a DB9 connector installed on the Generator Interface Board located in the Generator Cabinet. Communications Protocol This is a character protocol which involves the transmission of ASCII characters in full duplex with data flow control (XON/OFF Protocol). The default parameters are: D

Baud rate: 9600

D

com–port: Com 1

D

Parity: Even

D

Length: 07

D

Stop bits: 01

These parameters correspond to the connection with the Senographe DMR, but they can be modified for the connection with another machine (eg: 1200 bauds for Senix HF). 6–5

Emulator Restrictions This software is created specially to be used with the Senographe DMR and Senix HF. Therefore, this software emulates only those functions required for such use. The result is a compromise between the speed of the reply (loading and run time) and the level of compatibility required. The only function keys recognized are: D

Function keys used by the Senographe,

D

Cursor keys,

D

Four keys: Insertion, Backspace, Prev Screen, and Next Screen.

The emulator does not recognize display commands in large characters, semi–graphic, or underlined (due to the CGA LCD boards of the PC). Most of the cursor–positioning commands as well as publishing commands are available. The scrolling area is programmable. The cursor position and the usual character attributes can be stored and restored. This software’s performance is closer to a terminal than the standard ANSI.SYS file.

Type of Files Transferred Two main types of file are concerned by file transfer between PC and Senographe DMR: D

Coded files.

D

ASCII files.

8–2–1 Coded Files These are binary files which observe the Motorola Exormacs format. Coded files are used to transfer the Senographe calibration variables for back–up on floppy disk. The protocol selected ensures that the data transmitted are correct during PC to Equipment transfer. A special menu is used to check the file transmitted by the Senographe. If the transfer has run without error detection, it is certain that the file transferred can be reloaded on the Senographe. The software determines the end of the transmission when it receives a special frame described in the protocol. In the PC–to–Senographe transfer, the file type is not processed by the MAMMOCOM software. All the characters of the file are transmitted. 8–2–2 ASCII Files The ASCII files do not observe any format. The end of transmission is detected by reception of CTRL_Z. Statistics and error codes are transmitted according to this format.

SECTION 10 ACCESS TO DOS

The PC can remain connected to the Senographe, and all MAMMOCOM Software operating parameters are preserved. An advantage in running the MAMMOCOM Software from a floppy diskette is that this DOS accessing procedure is much faster than exiting STAV and restarting it. From the STAV Main Menu, select: DOS Shell. ILLUSTRATION 2–17 DOS SHELL SELECTION

DOS is accessed immediately. The program displays the “Type Exit to return to Terminal Emulator”. The Exit command is a standard command of MS–DOS and recognized by the COMMAND.COM interpreter. Once it is used, the STAV Main Menu reappears and the session can resume.

CAUTION

If the MAMMOCOM Software is run from a floppy disk, the MAMMOCOM should not contain an MS–DOS version which is incompatible with the PC. If the STAV finds a system on the current disk drive, it will use it in preference to the usual system of the PC. For simplicity, use a MAMMOCOM floppy disk without any system.

Changing the kV/mA board only D

Changing the kV/mA board alone IS NOT RECOMMENDED (see Section 3, above). However, if the change is absolutely necessary, the calibration procedure is given below:

1. Configure the Senographe DMR as follows: – magnification device in position 1.9, – Large focus, – 2–point mode, – 30 kV, 30 mAs. 2. Place the RMI 233 probe on the magnification plate, in the center of the X–ray beam. Connect the probe to an oscilloscope with memory facility – select scan 5 ms/division. 3. Execute an exposure and observe the beginning of the exposure waveform on the oscilloscope. Adjust P1 to obtain the shortest rise time, with no overshoot, as shown in the waveform 1 below:

message number subassembly ref. (hardware or software) number indicating origin of fault In the above example: E55 indicates an error concerning tube housing angulation and generating an exposure inhibition. 161/013 indicates no reference crossing during movement. E55 is the error code type listed in the Operator Manual. This code is easy to use and communicate, and is considered sufficient for customer use. 161/013 is the ”technical code”, recommended for GE internal communication. The error code listing currently contains almost 500 codes. Around 200 of these codes concern software errors which, by definition, should never occur. If a software error should occur, especially if it occurs several times, please inform Service Engineering, giving as many details as possible. If possible, provide the error codes file, on diskette (see DR 19). The error code listing, below, only contains codes ccc/ddd, to facilitate technical communication. The TSG (Trouble Shooting Guide) column indicates the reference number in the Trouble Shooting Guide (chapter 5), which should obviously be consulted first.

Note:

*** : these 3 stars indicates an explanation at the end of this chapter (section 3) for a possible known root cause.

Bucky calibration errors

5.8.1

118/011: Gain error

Job Card TSG 014

3 of 6

The DMR gantry software detects a gain error if the calculated gain is < 0.25 or equals 1.00. Using installation or maintenance menus, a warning message INVALID GAIN is displayed if: 0.25 < gain < 0.4. The gain must be between 0.5 and 0.6 for correct operation. If the gain is too high, it can induce a 118/012 error if the offset is too far from 0.5. Incorrect gain can induce grid lines The gain is affected by: 1. The distance between the magnet and the Hall sensor. Fine tuning of this distance is made by adjustment of the black screw on top of the magnet mounting. Loosen the two securing screws slightly, then adjust the black screw until the gain is in the range 0.5 to 0.6. Check the gain again after tightening the securing screws. 2. The electronic circuitry. 3. Of course, the quality of the magnet. 4. Jumper settings on the Gantry power board; refer to the Service Manual, Job Card IST 037. 5.8.2

118/010: Offset error The DMR gantry software detects an offset error if the calculated offset is < 0.20 or > 0.8. Using installation or maintenance menus, a Warning message: “INVALID OFFSET” is displayed if: 0.20 < offset < 0.35 or 0.65 < offset < 0.80. The offset value must be as close as possible to 0.5 (5.000 E–1).

1. The blade is not centered in the opto-interruptor. The LED DS2 must be OFF at both mechanical stops. 2. The magnet does not move perpendicularly respect to the Hall sensor. 3. The examination arm is tilted at " 90°. This effect is produced by grid weight. The normal offset shift is " 0.04. For example:

0.46 (4.600 E–1) with the tube tilted to the left. 0.50 (5.000 E–1) with the arm vertical. 0.54 (5.400 E–1) with the tube tilted to the right.

4. Fine tuning of the offset is made by moving the blade around the centered position until the offset is 0.5 +0.01 with the arm vertical. Note:

Under some circumstances, for example after calibration, the LED may be ON at the electronic end-of-travel position. This is normal.

A few hints about grid components

5.9.1

Hall effect sensor

Job Card TSG 014

5 of 6

Hall sensor output is +4 V (" 50 mV) without any magnetic field measured on TP1/TP2 (800–PL10). With the magnet flying above the sensor, the output varies in the range +2.0 to +6.0 volts. Perfect symmetry around 4 volts is not mandatory, depending on magnet / sensor distance. Output levels depend on the gain adjustment (magnet distance; refer to section 5.8.1). Maximum positive value is obtained when grid carriage is away (far) from motor side. 5.9.2

Grid motor Typical impedance of the voice coil is five ohms (connector J2 on 800PL10). Longitudinal motor shaft travel must be free (no hard spots). Note that rotating the motor shaft will destroy the voice coil.

5.9.3

Definition of gain & offset Gain = (MAX – MIN) / A Offset = (MAX + MIN) / (2* A) with A = 65535 Example: If MAX = 60000 and MIN = 15000 Then gain = 0.69 and Offset = 0.57

Note:

Remember the drive is made on 16 bits with a 12 (upper) bit resolution. So maximum displayed value is hex FFF0 = 65520 decimal (6.552 E+4 in scientific notation).

Note:

Board 800PL10 and the motor are not FRU parts, because adjustment requires a special tool. If these parts are diagnosed as faulty, a complete bucky must be ordered.

The console delivered with the DMR+ uses a key combination to start the auto-test. However, you may find an older model of console which uses a switch. Entry to the auto-test for both models is described here; they are otherwise completely compatible. Autotest using key combination If your console is the newer model without the switch 100 S1, you must simultaneously press a combination of five switches to start the autotest: – First press and hold the Reset button (1) and the Centering Light button (2) – Then press and hold the three buttons Film Density decrement (3), Film Density increment (4), and Screen/Film combination (5). The autotest starts as described below. To stop the test, repeat the same key combination at any time after the lamp visual test.

Job Card TSG 020

Autotest for consoles with switch 100 S1 If your console has the switch 100 S1 (located next to connector XJ3), start the autotest as follows: – Turn OFF the Senographe DMR+. – Use small flat screwdriver to set the switch 100 S1 to its CENTER position (see Note). –Power up the DMR+. To stop the autotest sequence, switch S1 may be returned to its normal position (LEFT) at any time. This results in a console CPU reset and restoration of the serial link with the generator. If S1 is returned to its normal application position during a test, the test is completed before the change in position is recognized. This means that several seconds may be necessary before return to normal application mode.

Note:

5.3

This switch has 3 positions: LEFT, CENTER and RIGHT. LEFT is the normal application position. CENTER is for console self-test, RIGHT is not used. If the Senographe DMR+ is powered up with this switch in the RIGHT position, correct power-up is impossible. The console ”beeps” at 1-second intervals, communication with the service terminal is impossible, and the serial link with the generator is interrupted. Autotest sequence. An automatic sequence of console self tests is executed in the following order: – Buzzer test (300 ms). – Internal CPU RAM test. – External CPU RAM test. – Internal CPU timer test. – Serial link loop–back test. – Alpha–numeric display test. – Visual test of 6 lamps inside console keys. – Electrical consumption test: all displays and lamps are lit for 5 seconds

TROUBLESHOOTING

Note:

The first five tests (to the serial link test) are followed by a message (OK or NOT OK) on the console display. At the end of this sequence, ”Operator input test” is displayed on the left–hand console display; the following tests require operator input: – Key tests: service engineer momentarily presses each key (except 1st and 2nd trigger) on the console; the left–hand display shows the function of the key being pressed

Note:

If the console is equipped with a remote handswitch, its light centering button (but not 1st and 2nd trigger buttons) must also be tested during the key tests. – kV and mAs knob tests: service engineer rotates each knob step by step through each of its 12 absolute positions, which are displayed on the left–hand display. The right–hand display shows relative knob positions.

5.4

Corrective action if a test is declared ”NOT OK”. If any test result is ”NOT OK”, replace the console.
