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 Interna-
tional 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 Comi-
sión 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 unbe-
fugter oder unqualifizierter Personen wird er zu einer Gefahrenquelle. Übermäßige Röntgenbestrahlung ist für den menschlichen Orga-
nismus 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 ge-
fahrlosen 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 toGantry 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.
1–5 Block Diagrams
Block Diagrams for the various parts of the system are provided in Chapter 6.

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:
� Level “1” on TP27 on board 400PL2 (�
����
������
�� and.
� 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 :
� Generator : 400PL3 and 400PL2,
� 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.

1–3
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.

CHAPTER 2 – “MAMMOCOM” COMMUNICATION SOFTWARE
SECTION 1
PURPOSE OF THE SOFTWARE
The MAMMOCOM Communication Software provides the connection from the Senographe
DMR to a PC (laptop)* to access GEMS-reserved maintenance tests.
The software is composed of several operating modules:
� ANSI–compatible VT200 terminal emulator (restricted).
� On–line Help on the various Senographe menus.
� File transfer modules between the Senographe and the PC.
Note: The terminal emulator menu (and this menu only) can also be used on the Senix (set
transmission speed to 1200 bauds).
Note: MAMMOCOM can also be run under Windows, inside a DOS window (using full screen
or not). In this case the creation of a “PIF” file is recommended; see your Windows
documentation.
* Any 8088, 8086, 80286 or 80386 microprocessor–based computer operating under 
MS–DOS (Version 2.1 or higher)
SECTION 2
“MAMMOCOM” FLOPPY DISK CONTENTS
The content of the MAMMOCOM floppy disk is classified as PROPRIETARY.

TERMINAL EMULATOR MESSAGE
TERMINAL EMULATOR
CTRL–D : Disconnect F 10 : Connect Alt–M : Main menu
The cursor appears in the top lefthand corner of the screen.
A VT200 terminal displays 24 lines of 80 characters. The PC has a screen of 25 lines. Line
25 displays a prompt message for the main access functions to the Senographe:
� F10:
This key is used to connect to the Senographe DMR and Senographe 600T Senix HF (the
communications parameters should be modified for the latter).
Note: Connection to the Senographe DMR can be made via this software only, as no other
terminal emulator is recognized by the Senographe.
� CTRL–D:
Used to disconnect the two Senographe units.
� Alt–M:
Used to return to the Main Menu of the MAMMOCOM software without breaking the
connection. This means that a later selection of the terminal emulator returns the screen
displayed before Alt–M was hit, and dialog with the Senographe can take up where it left
off. This function is necessary to return to the Help Menus or to transfer files.
The seven PC keys, F1 thru F6 and F9, simulate the seven keys surrounding the DMR console
readouts and give access to all the menus (Medical, Installation, and Maintenance).

6–3 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.
6–4 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:
� Baud rate: 9600
� com–port: Com 1
� Parity: Even
� Length: 07
� 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:
� Function keys used by the Senographe,
� Cursor keys,
� 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.

SECTION 8
FILE TRANSMISSION
This menu is used to transfer DMR files to the PC, and vice–versa.
Two types of file are concerned:
� Text files in any format.
� Encoded files with the Motorola Exormacs protocol.
8–1 Preparing the Transfer
The system must be in emulation to make a file transfer. The file transfer runs as follows:
1. To link up with the DMR, place the terminal in emulation, as follows: at MAMMOCOM
start–up, select the Terminal Emulator and connect to the Senographe by pressing F10.
2. Run the menu tree structure on the DMR until the Transfer Menu is reached.
The possibilities are as follows:
– Arm error codes transfer: @<5409>
– Arm data save: @<5421>
– Arm data load: @<5422>
– Gene error codes transfer: @<0314>
– Gene data save: @<0361>
– Gene data load: @<0362>
– Gene statistics transfer: @<0278>
Where @<xxxxx> is the Maintenance screen Number, refer to the tree structures in
Chapter 1.
3. In emulation, line No. 25 gives the following commands:
Ctrl–D: Disconnect F10: Connect Alt–M: Main Menu
4. Hit <Alt>–<M> to access the Main Menu without disconnecting from the Senographe.
5. Select: File Transmission.

8–2 Type of Files Transferred
Two main types of file are concerned by file transfer between PC and Senographe DMR:
� Coded files.
� 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.

When the current value of one of the parameters is modified, the Save option generates the
STAV.DAT File in the Current Directory.
At each subsequent use of the MAMMOCOM Software, the values contained in the file are
taken by default.
If this file contains both the communications parameters and the names of the sub–directories
