Working with the service PC 1 - 3

Configuration of the service PC 1

All Service Programs use the RS232 port in order to communicate with the MAMMOMAT. This port is usually handled as COM1 by the OS of the service PC. Modern PC’s can be equipped with new types of communication hardware, e.g. infrared port and built-in modem, which may act as COM1 or share resources with COM1. This could cause malfunction of the Service Programs for the MAMMOMAT, which req uires the OS and computer BIOS to be re-configured.

The following procedures are designed to ensure general compatibility with the OS’s Windows

95, Windows® 98 and Windows® 2000 Pro on modern PC’s. If the setti ngs are

saved, this procedure has to be done only once.

Configuration of computer BIOS 1

1. Enter the BIOS setup, usually done by pres sing e.g. <F2> during the boot sequence of the BIOS.

2. Find the configuration of the I rDA (Infrared device) port and disable it.

3. Find the configuration of a buil t-in modem and make sure it is configured as COM3.

4. Find the configuration of COM1 and make sure it use s the interrupt IRQ 4 and the memory address range 03F8 - 03FF.

5. Save the BIOS settings and restart the PC.

Configuration of Windows

(This example is for Windows® 2000 Pro. Windows® 95 and Windows® 98 have a similar approach, consult the OS documentation for details .)

1. Choose Settings from the Start Menu.

2. Choose Control Panel.

3. Choose System.

4. Choose the tab Hardware.

5. Press the button Device Manager. If the IrDA-port was disabled in the c omputer BIOS, it should not be present in the list of available hardware. If the IrDA is present anyway and its icon is not marked with a red cross:

6. Double-click on the device row.

7. Choose the tab General In the appearing dialog box .

8. In the section Device Usage, change the statu s to "Disabled in the current hardware profile".

9. Exit the dialog by pressing the OK-button.

Having performed the described configurations above, the Service Program should be able to run without difficulties.

• after AEC reset installation parameters. In a two wi ng M3000 normalize both detectors.

When performing detector normalizations:

• The detector is to be in chestwall position.

• The AEC calibration plexi (part no. 65 61 240) must extend at l east 10 mm beyond the

chestwall edge of the table and be center ed.

The following e xposures are to be made:

• with no cassette or film

• with the very same AEC calibration plexi and object table.

It is strongly suggested that y ou use a Grid 18x24 object table (Bucky).

1. Make sure a backup floppy is inserted.

2. In <Mainmenu> select <Configuratio n>, <AEC> and <Detector normalization>.

This menu is used for:

• Installation of correction tables (F2).

• Calibration of correction tables (F3), in cluding rough setting of sens itivity correction.

The AEC uses one correction table for each Anode/Filter/Speed combination. Each correction table has separ ate co rrections for each object t abl e group (Ma gnificat ion, Grid, No grid and Stereo). When pressing <F2> a dialog box will appear, in which the ID of the correction table to be instal led (from floppy disk) should be entered. When the transaction of the correction table to the AEC is finishe d, the program will automatically go on to the calibration process.

To enter the calibration process without having installed new correction tables, press <F3>. When pressing <F3> correction tables previously installed will be loaded from the AEC. See “Installation and Start-Up Instructions” for further information.

2 - 10 Adjustment and Service PC Programs

During the calibration process of a correction table calibration reference data is fetched from a calibration file (“calxxxx.txt”, in which the four x:es represent the ID number). The ID of this file is the same as f or the corr ection tab l e in use and is located on the floppy containing the AEC correction tables (original AEC correction tables shall normally be copied from the floppy "AEC correction tables" to a backup floppy). The backup floppy m ust be inserted during the entire calibration.

When pressing <F2> exposure data f rom the cal ibration process is stored in a result file, e.g. “mrgh.txt”, on thi s floppy. In “mrgh.txt” the first letter rep resents t ype of anode (“m” fo r molly or “w” for wolfram/tungsten), the second represents type of filter (“m” for molly or “r” for rhodium), the third represents the ki nd of object table (“g” for grid, “n” for no grid, “s” for stereo or “m” for magnification) and the fourth represents the speed (“h” for high or “d” for detailed).

Enable or disab le OPCOMP. A correct input code will enable OPCOMP.

Adapting OPCOMP

If the factory-set OPCOMP is not to the customer’s satisfaction, an adjustment can be made with the tautness factors in the “Optimiz ed compression” table. A lower tautness value will increase the compression force and vice versa.

M1000/3000/3000 Nova Register 5 SPB7-230.114.03 Page 30 of 64 Siemens-Elema AB Service Program Rev. 05 02.03 SPS-UD Solna, Sweden

Increase/decrease the tautness factor by e.g. 10 the first time. Let the cust omer use this setting for at least two w eeks, before further changes are made.

NOTE

OPCOMP has been thoroughly tested b y Siemens. If any factors are changed, OPCOMP will no longer be an optimization of compression force and image quality according to Siemens’ clinical test.

Tautness factor 18x24

This factor determines how hard a breast is pressed. Lower tautness factor gives more pressure to the breast.

Tautness factor 24x30

This factor determines how hard a breast is pressed. Lower tautness factor gives more pressure to the breast.

Tautness factor mag 15 (not used)

This factor determines how hard a breast is pressed when a magnification table 1.5 is attached. Lower tautness factor gives more pressure to the breast.

Description

If the master processor (D702) cannot activate the AEC processor (D701) via the serial interface any more, or if any important data from the control deck is missing, the above mentioned error is displayed.

Fault elimination

First you must chec k if PC board D701 is plugged in correct ly and if the connections to the power supply and to the serial interface (see wiring diagram) function correctly.

If no fault can be found, PC board D701 or D702 should be replaced.

Er 005 “Flash in AEC is defective or not correctly initiated.”

Displayed on PC: Flash in AEC is defective or not correctly initiated

Description

During initialization, the AEC processor (D701) checks the data stored in its E2PROM by means of stored check sums. If these data are incorrect or if the E processor informs the master processor via the serial interfac e and the above mentioned error is displayed.

The master also generates this error i f, during exposure release, no communication with the AEC has been established yet.

PROM fails, the AEC

NOTE

As opposed to this, error 004 appears if communication started with the master is disturbed.

Fault elimination

Reprogram E2PROM or replace E2PR OM or PC board D701. Repr ogram with t he service PC, menu Backup.

Er 008 “Stand not ready”

Displayed on PC: Communication master <-> stand disturbed or stand not ready

Description

This error means that the communication between master processor and unit processor via the serial interface is faulty or interrupted.

Fault elimination

Check if the power supply and th e serial interface (s ee wiring diagr am) to the un it functi on correctly.

Displayed on PC: Exposure aborted by user

Description

If the exposure buttons are released prematurely, the exposur e is aborted immediately. On the control deck, the LIMIT LED (→0←) lights up, an acoustic signal sounds and the above-menti oned error is displayed.

Fault elimination

This error indication i s only for information and requi res no further action. Should i t appear frequently, however, check the contacts of the exposure release buttons. Replace exposure release button(s), if necessary.

Er 012 “Time limit reached”

Displayed on PC: Time limit reached

Description

In order to prev ent t he tube assemb ly from o v erload, a timer runs during e xposure . This is set with the time limit before exposure. If this timer runs down, the exposure is aborted immediately, and the above error message is displayed. Depending on the mode of operation, the time limit is calculat ed as fol lows:

AEC mode

The time limit is the power- dependent load time plus a tolerance value (approx. 400 ms).

mAs mode

The time limit is the calculated exposure time plus a certain reserve. If this period is shorter than 2 s, 2 s are assumed. If it exceeds 2 s, a reserve of 400 ms is added.

The time limit can be read off in ms with the se rvice PC in “normal mode” under item “AEC data”. The value shown here does not include the extra 400 ms.

Fault elimination

The tube current and the filament current must be measured again with the oscilloscope (test points I read off with the service PC in normal mode.

Er 812 “Compression Protect Error”

Displayed on PC: Compression protect switch not OK in stand

Description

This signal is used to check the proper oper ation of the compression protect relay (Kl) on the motor board (D802). The CPU (D801) reads the signal after a short delay after releasing the compression pedal in order to ch ec k that the relay has opened and disabled motor running in the compression direction. Note that the test point on D802 is protected with 4,75k.

Fault elimination, trouble shooting

Normal active level 9V (test point COMP_PROT on D802). If the level is OV check 14V and Kl on the motor board or look for short circuit on the ribbon cable between D801 and D802. If the cable is OK, D802 should be replaced.

If the voltage is 18V on the te st point, the ribbon cable is open or D801 faulty. If the voltage is OK replace D801.

Er 813 “Compression OK Error”

Displayed on PC: Compression Motor controller, or motor, error in stand

Description

This signal indicates an over current or lack of voltage (5V or 15V) i n the compression motor drive. If o ver current, the signal appears after about 2 s and disappears after about 0,5 s. The signal causes D801 to stop sending pulses to the compression drive and thus disables the compression motor. The red LED “comp error”, V2 lights when error (comp_ok signal low) e xcept if 5V is missing.There is no test point.

Fault elimination, trouble shooting

If V2 is lit steadily, chec k fuses F3 (24V) and F2 (24VF & l5V). l5V is indicat ed by LED V49 and can be measured at test point l5V on D802. Test point 24VF should measure about 30V unloaded. 5V is indicated by LED V7 and test point 5V on D802. If 5V and 14V (normally about 18V unloaded) are missing check Fl on D801. Missing voltages can also be caused by an open connection in Emergency Stop Switch S880.

Over current is most likely caused by a faulty motor , mechanic al o verloading of motorized movement, short-circuited wiring or D805 or faulty D802.

At the two positions, the te st point COLL_Pl at CPU board (D801) is high (5V), and in between it is low (0V). The test point value can also be read by the service program. “Stand tests/Switches” will show al l s witches , and the one that corresponds to COLL_Pl is named Collimator position 18x24.

Fault elimination, trouble shooting

Switch between 24x30 and 18x24 object tab les and check if the collimator plate moves at all.

If it does not move:

- Check if the CPU sends out pulses, COLL_ST test point on D801, if not, replace D801.

- Check if the wing board (D805) receives pulses, te st point COLL_ST on D805, if not check cables and connectors between D801 and D805.

- Check voltages on wing board 5V and 14V.

- Check STEP_ENABLE test point on D805, it should be low (0V) when pulses are output to the motor.

- Check if it is at an end position, and the direction is into the end. Direction test point COLL_D at D805 should be low (0V) when moving collimator towards the patient. If something is wrong, check cables and connector s.

If it moves:

- Check if the collimator position 18x24 light switch works as in the description above.

- Check if it moves the whole time of 8 s. If it does but apparently not reaches the other position in time, then something may be in the way that slows the speed down, or the motor may be faulty. In the last case, try changing the motor.

- If the motor stops after just a short time, either the motor or the wing board (D805) is faulty. Try replacing one of them.

Err 817 “Filter move error”

Displayed on PC: Filter fails to reach correct position in time

Description

The filter control function on CPU board (D801) will output st epper motor pulses until the new filter position can be sensed. The test point FILT P will show the status of filter position sensor. At any of the three filter positions FILT P will be low (0, 0V). A short distance from the position, in either di recti on, FILT P wi ll be hig h (1, 5V). This r emains for a certain number of stepper motor steps, different for the three filter positions, until there is a long part where FILT P is low again. The test point value can also be read by the service program. “Stand tests/Switches” will show all switches.

The error is displayed if no area where th e FI LT P sensor is high, for the cho sen f ilt er, can be found within a certain number of stepper motor steps.

Fault elimination, trouble shooting

Switch between the three anode/filter combinations on the control panel and check if the filter disc moves at all.

If it does not mov e:

- check if the CPU sends out pulses to the wing board, FILT ST test point on D805, if not, check cabl es and connectors between D801 and D805 and maybe replace CPU board (D801) or wing board (D805).

- check voltages on wing board, 5V and 14V.

- check STEP ENABLE test point on D805, it should be low (0V) when pul ses are output to the motor.

If it moves:

- check if the filter position light switch works as in the descri p tion above.

- check if it moves just slowly, then something may be in the way that slows the speed down, or the motor may be faulty. In t he last case, tr y changing the motor.

- if the motor stops after just a short time either the motor or the wing board (D805) is faulty. Try replacing one of them.

Er 819 “Drive Protec t Error”

Displayed on PC: Drive protect switch not OK (lift and rotation), in stand

Description

This signal is used to check the proper operation of the drive protect relay (K6) on the motor board (D802). The CPU (D801) reads the signal after a short delay after rel easing the activated l ift or rotati on button i n order to chec k that t he rela y has opened and di sabled motor running.

Fault elimination, trouble shooting

Normal active level 5V (test point DRIVE_PROT on D802). If the level is 0V check 24VF and K3 on the motor board or look for short circuit on the ribbon cable between D801 and D802. If the cable is OK, D802 should be replaced.

If the voltage is 30V on the te st point, the ribbon cable is open or D801 faulty. If the voltage is OK replace D801.

NOTE

Overloading is possible due to improper balancing (adjustment of the spring or improper loading of the lifting carriage) or improper adjus tment of the rot ation brake. Faulty motor, short-circuited wiring or faulty D802 are other possible causes.

There is no corresponding error for the li ft & rotation drive to Compression OK error. If this fault occurs, D801 stops sending pulses to D802 and the selected motor stops. The LED V12, DRIVE_ERROR functions in the same manner as COMP_ERROR. Note that the current limit is lower when the lift motor is running downwards. If there are problems with lift or rotation operation indicating over-load, look at the DRIVE_ERROR LED to determine if the motor is overloaded.

Er 820 “E2PROM write error”

Displayed on PC: Write/read back failure with EEPROM in stand

Description

If data are stored in the stand E2PROM (D801.I34) during adjustment, a check is performed to verify whether they have been correctly stored. Should differences occur, the above-menti oned error is displayed.

Fault elimination

Repeat the attempt to write in the E2PROM. Should this not lead to any result, in spi te of repeated attempts, the board D801 must be exchanged. A reinstallation of all stand parameters must be carried out. Use the service PC to reinstall the stand par ameters from floppy or disk.
