Prerequisites 1-1
Meters and appliances, tools, notes
Meters and appliances required
NOTE!
Calibrated instruments are required.
• Line resistance meter 44 15 733 RV090.
• Protective ground-wire tester 44 15 899 RV090.
• Oscilloscope, e.g TEKTRONIX 314.
• Digital multimeter incl. mAs meter.
• Densitometer e.g PDA 81.
• Service PC (e.g Siemens-Nixdorf PCD 3NSX/20 or similar) with connecting cable
(PC-Generator), part no. 96 00 440 RE999.
• Normi 7 test body (provided by the customer) or SIB phantom Type 42 001 (PTW or
INAK).
• Centring cross, part no. 96 60 051 RE 999.
• Plexiglass plates, three plates measuring150 mm x 150 mm x 20 mm and one plate
measuring 150 mm x 150 mm x 10 mm, part no. 85 49 438 and 97 88 423 respective-
ly.
WARNING!
For safety reasons, the existing protective ground conductor in the power cord must un-
der no circumstances be disconnected when operating the oscilloscope. For those mea-
surements, in which any resulting ground loop may falsify the measuring result, use the
differential amplifier (difference measurement).
Tools required
• Standard installation tool kit.
• Torque wrench for bolting the stand/generator to the floor (optional).
• Electrical screwdriver with adjustable torque is recommended.
NOTE!
Checks and /or adjustments, which must be made with X-ray radiation switched on, are
marked with the radiation warning symbol:

1-2 Prerequisites
Start-up, DHHS and X-ray decree area of application
Important notes on start-up
The MAMMOMAT 300 is adjusted, programmed and tested in the factory, leaving only
the adaption to the on-site mains voltage and the functional tests to be performed.
When the measurements to be made (kV, mAs, etc.) are within the tolerances stated in
these instructions, this confirms that the settings made in the factory have not changed and
the equipment is fully serviceable.
The measured values marked with >> in section 11 shall be entered in the test certificate
provided.
The service PC is required only for programming according to:
• Section 11, Checks with high voltage
• Section 12, Start-up and functional test of the Iontomat
Programming the "Correction curve"
Setting the "sensitivity" (film density)
Setting the "sensitivity correction" (adaption to different exposure techniques)
• Section 13, Further programming
• Section 19, Final procedures
Recording the programmed values.
Reading the exposure counter and deleting the error memory.
NOTE!
If the generator is switched off with the Service PC connected, wait approximately 5 sec-
onds before switching it on again.
Checking and recording for the area of application of the X-ray decree
(§16 Germany)
In the area of application of the X-ray decree, an acceptance test certificate is supplied,
with most of the data filled in by the factory.
Only:
• the cut-off dose
• the resolution of the film/screen systems used, and
• the output values of the constancy test
must be determined by the owner of the equipment and recorded in the acceptance test
certificate. Furthermore, the front page of the acceptance test certificate must also be com-
pleted with the operator´s data.

Solna, Sweden 05.98 65 02 186
Prerequisites 1-3
Checking and recording for the DHHS area of application
In the area of application of the DHHS regulations, maintenance measurements must be
made according to the instructions "DHHS Maintenance Schedule and User´s Spot
Checks" RX B7-120.101... (included in the "DHHS Supplements to the operating instruc-
tions" RX B7-120.203...).
Sections
• Required labels.
• Radiation ON indicators.
• Manual termination of exposure.
• Checking the maximum adjustable mAs with the following kV-values.
• Filters in beam limiting device (BLD).
• Reproducibility.
• kVp-accuracy.
• mAs-accuracy.
• Automatic exposure control (AEC).
• Coincidence of radiation field/image receptor.
• Alignment of light field/x-ray field.
• Illuminance of light localizer (light field).
• Shut-down of motor-driven compression movement.
The result must be recorded in "Measurement certificate" RX B7-120.037...
Some of the values to be determined can be taken from the acceptance test certificate.
The radiation-field limitation is set at the factory and recorded in the acceptance test cer-
tificate.
If the measurements to be made concerning the radiation-field limitation are within the
tolerances stated in these instructions, this confirms that the settings made at the factory
have not changed.
Note on delivery state
The MAMMOMAT 300 has been tested and adjusted at the factory, and should therefore
be ready for operation after completion of the installation.

Protective measures
Prior to any intervention in the equipment, disconnect it from the power
supply with the main circuit-breaker.
WARNING!
If the system is only switched off at the control panel or with S2/D711, line voltage will
still be present at the generator line connection, line filter Z1, Z2, transformer T1, trans-
former T10 and p.c. board D711 (see wiring diagram).
Topreventaccidentaltriggeringofhighvoltagecableandradiation,settheswitch S2(SS)
on p.c board D702 to "OFF" (lower position) (no triggering of the SS relay).
WARNING!
After shut-down of the system, there may still be about 380 V DC present on the interme-
diate circuit. This will be indicated by LED V24 on p.c. board D 710. The voltage will
drop to less than 30 V within about 3 minutes, the LED goes out at about 30 V.
CAUTION!
The p.c. boards contain electrostatic highly sensitive components requiring particular
care in their handling (ground before making contact and place only on a conductive sur-
face, see Technical Information TI 219).
Before removing or inserting a p.c. board, switch off the equipment.
