Error messages of the master Err 0XX 0
A malfunction detected by the system is indicated by " Err" followed by a three-digit error
code on the kV and mAs displays of the control panel. This can be acknowledged by the
operator pressing the limit button. Exceeded limits are also deleted with the limit button.
Err 004
“Communication master - AEC disturbed or AEC not ready”
Description
If the master processor (D750) can no longer activate the AEC processor via the serial
interface or if any important data from the control deck is missing, the above error message is displayed.
Fault elimination
First check if PC board D750 is plugged in correctly and if the connections to the power
supply and the serial interface (see wiring diagram) are functioning correctly.
If no fault can be found, PC board D750 should be replaced.
Err 005
“Flash in AEC is defective or not correctly initiated”
Description
During initialization, the AEC processor (D750) checks the data stored in its E
2
means of stored checksums. If this data is incorrect or if the E
PROM fails, the AEC pro-
2
PROM by
cessor informs the master processor via the serial interface and the above error message
is displayed.
The master also generates this error if communication has not been established with the
AEC during exposure release.
NOTE
In contrast, error 004 appears if communication started with the
master disturbed.
Fault elimination
Reprogram E2PROM or replace E2PROM or PC board D750. Reprogram using the service PC "Backup" menu.
Err 008
“Communication master - stand disturbed or stand not ready”
Description
This error means that communication between the master processor and unit processor
via the serial interface is faulty or interrupted.
Fault elimination
Check whether the power supply and the serial interface (see wiring diagram) to the unit
are functioning correctly.

Error messages 7
Err 011
“Exposure aborted by user”
Description
If the exposure buttons are released prematurely, exposure is aborted immediately. On
the control deck, the LIMIT LED (→0←) lights up, an acoustic signal sounds and the
above error message is displayed.
Fault elimination
This error indication is purely informational and does not require further action. Should it
appear frequently, however, check the contacts of the exposure release buttons. Replace
the exposure release button(s), if necessary.
Err 012
“Time limit reached”
Description
In order to prevent the tube assembly from overloading, a timer runs during exposure.
This is set to the time limit prior to 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 calculated as follows:
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 time of 400 ms is added.
The time limit can be read off in ms with the service 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 MA_ACT and FIL_CURR_ACT on D750). The nominal and actual value of the
tube current can be read off with the service PC in normal mode. If the actual tube current
is too low, you must first ensure that the dynamic learn filament current (DLF switch) is
switched on. The tube must be readjusted in any case. Should difficulties still occur, the
tube current actual value acquisition must be checked (see wiring diagram).
Err 013
“mAs limit reached in AEC exposure”
Description
For safety reasons, the accumulated mAs is integrated via the timer independently of the
AEC during AEC exposures. If a focus, tube assembly and kV-dependent time limit (see
table) is obtained without the AEC being switched off, the exposure is aborted and the
above error message is displayed.

assembly is at a distance from the floor that could result in collision. These operator errors
are indicated on the control panel (the LED at the corresponding symbol lights up). Should
the control panel nevertheless allow start of exposure, this might be due to a bit error during the transmission of data between the stand and the control panel. As a precautionary
measure, the stand also checks whether the conditions are fulfilled. If this is not the case,
error message 811 is generated.

“Compression protect switch not OK in stand”
Description
This signal is used to check for proper operation 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 check that the relay has opened and disabled motor
operation in the compression direction. Note that the test point on D802 is protected with
4.75k.
Fault elimination, troubleshooting
Check the fuses on board D802. 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 a short circuit on
the ribbon cable between D801 and D802. If the cable is OK, D802 should be replaced.
If the voltage is 18V at the test point, the ribbon cable is open or D801 is faulty.
If the voltage is OK, replace D801.
Err 813
“Compression Motor controller, or motor, error in stand”
Description
This signal indicates an overcurrent or lack of voltage (5V or 15V) in the compression
motor drive. In the case of an overcurrent, 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) except if 5V is missing. There is no test point.
Fault elimination, troubleshooting
If V2 is lit steadily, check fuses F3 (24V) and F2 (24VF & l5V). l5V is indicated by LED
V49 and can be measured at test point l5V on D802. Test point 24VF should measure
about 30V in an unloaded state. 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.
Overcurrent is most likely caused by a faulty motor, mechanical overloading of motorized
movement, short-circuited wiring of D805 or a faulty D802.
Err 815
“Compression speed too high, error suspected in stand”
Description
The CPU (D801) has detected a compression speed greater than 13 cm/s. The software
causes the compression motor to reverse direction.
Fault elimination, troubleshooting
This error can be caused by play in the compression unit, defective compression measurement hardware, or a short-circuited power stage on the motor board. In the first two
cases, replace the compression unit and recalibrate the compression values with the service PC program. In the third case, the compression motor will run at a max. speed
upwards except when a compression pedal is pressed. It is not certain that error 815 will
appear. Replace D802.

“Collimator fails to reach correct position in time”
Description
Time out for filter lamella positioning during startup.
Fault elimination, troubleshooting
Check whether the collimator plates move at all.
If the collimator plates do not move:
- Check whether the CPU is sending out pulses, COLL_ST test point on D801, if not,
replace D801.
- Check whether the wing board (D805) is receiving pulses, test point COLL_ST on
D805; if not, check the cables and connectors between D801 and D805.
- Check voltages on the wing board.
- Check STEP_ENABLE test point on D805. It should be low (0V) when pulses are output to the motor.
If the collimator plates do move:
- Check whether the collimator position light switch is functioning as in the description
above.
- Check whether it moves for the entire 8 s. If it does but apparently does not reach the
other position in time, something may be in the way and slowing the speed, or the
motor may be faulty. In the latter case, try replacing 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.
- Check collimator calibration (lamp and/or X-ray field).
If not successful, replace collimator and/or D814.

“Drive protect switch not OK (lift and rotation), in stand”
Description
This signal is used to check for proper operation of the drive protect relay (K6) on the
motor board (D802). The CPU (D801) reads the signal after a short delay after releasing
the activated lift or rotation button in order to check that the relay has opened and disabled motor operation.
Fault elimination, troubleshooting
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 a short circuit on the ribbon cable between D801
and D802. If the cable is OK, D802 should be replaced.
If the voltage is 30V at the test point, the ribbon cable is open or D801 is faulty.
If the voltage is OK, replace D801.
NOTE
There is no error for the lift & rotation drive corresponding to the
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 moving
downward. If there are problems with lift or rotation operation indicating an overload, look at the DRIVE_ERROR LED to determine
if the motor is overloaded.
Overloading is possible due to improper balancing (adjustment of the spring or improper
loading of the lifting carriage) or improper adjustment of the rotation brake. Faulty motor,
short-circuited wiring or faulty D802 are other possible causes.

“Grid failed to move properly”
Description
The grid has to move properly from the start. This is supervised by the CPU. The CPU
measures the time from start till the grid has reached one of the end positions and then is
able to leave it. To check that the grid is functioning properly and does not jam, the time
the grid requires to move between the two end positions is also measured the first time. If
the time for start or run check exceeds 2 sec., this error appears.
Fault elimination, troubleshooting
Check programming of the grid fast speed (normally 80%) and the grid fast speed time
(normally 500 ms).
Check the bucky board. First try another board. Make sure the grid moves freely along its
entire travel path in both directions.
Check the output voltage at test point GRID_M on D802. At 80% speed and nominally
30V on 24VF, GRID_M should be 30 - 0.8*30 = 6V during fast grid movement. Check for
possible short circuits if the signal remains at about 30V. This voltage goes to the bucky
via board D805 and its relay Kl. Test point GRID_SP on D802 is the control signal from
D801. It is a 5V, 20 kHz PWM signal. At 80% speed, the signal should be low at about 40
µs and high at about 10 µs per period. Replace D802 if the correct output is not achieved
despite proper input, cabling and bucky.

“One or more potentiometers seem to have lost contact with stand”
Description
The four potentiometers, R803-tube angle, R871-preset angle, R861-preset force and
R863-thickness, have their return current through signal pot_return. This is done to
assure that no potentiometer is missing or partly disconnected so that it can yield a value
leading to improper stand operation. During stand configuration or after replacing a potentiometer or the compression unit, the correct value for the signal potentiometer check
must be read and stored in the stand’s E
2
PROM with the service PC program. This error
is reported if the measured value is more than 32 bits less than the programmed value.
Fault elimination, troubleshooting
Check that all potentiometers are functioning properly. An error can be caused by an open
connection, connector or potentiometer. If all four potentiometers are functioning properly,
check the programming of the potentiometer check and correct it. The need for such an
adjustment may indicate a potentiometer is about to fail.

“There is a short circuit somewhere among potentiometers in stand”
Description
The same circuitry as Err 825 is used. In this case the error indicates that the value is

Fault elimination, troubleshooting
Check the actual and programmed pot. check values with the service PC program. If the
value is only slightly too high, check all potentiometers for mechanical damage or sensitivity. A short circuit (pot. or wiring) should yield the max. value for pot_check (3FF).

Some files on Mammomat Novation system contain information about processes on the
system. This information could be helpful for determination of failure, detector artifacts,
communications problems, blue screen and automatic reboot of the WH AWS.The analysis of the files requires specific knowledge. For this reason, if support is required, the files
have to be sent to USC/HSC.
If support by USC/HSC is requested, groups of files have to be sent for explicit analysis:
• MPxxxx.smj, MPxxxx.map, qualify.log,MPxxxx.cfg and drapi.log: They are locat-
ed under WH AWS in folder C:\AWS\drul\data\.
• Brick files: These files can be shown by using the PCMX Web software.
• Savelog files: a feature on the syngo SW is implemented for extracting the files and
burning them onto CD (only as of SW VA11x).
• Windows Event log.
• syngo logs. They are located under WH AWS in folder C:\AWS\log\*.*
• Dump files (if available). They are located under WH AWS in folder C:\winnt\
minidump\*.dmp.
• brickspy.tar.gz file.

The generator section of the Mammomat Novation is of modular construction. The modules were developed so that, in general, no settings need be made when they are
replaced. If an error occurs in the generator (radiation generation), different signals can
be measured or checked in order to delineate or to localize the error.

Failure Check Measures to be taken if not OK
Control panel
not working
at switch-on
LEDs: “+5VD,
-15 V, +15 V and
28Vprim on
mains input converter
If all LEDs are off, check if there is input voltage at
the input terminals and if S700 is ON.
If there is voltage and S700 is ON, then the mains
input converter is probably defective and must be
replaced. Remember to switch off the input voltage
before disconnecting this unit.
If only one or some of the LEDs are off, switch off
S700 and disconnect the cables from X700, X701,
X705 and X706. If the LEDs still are off when you
switch on S700, then the mains input converter is
probably defective and must be replaced. Remember
to switch off the input voltage before disconnecting
this unit.
If all LEDs are on when you switch on S 700, then the
problem cable has to be identified. If the cable connected to X 700 is causing the failure, then the problem is either the HV inverter or the tube power
supply. If the failure remains after the cable to connector X720 on the tube power supply has been disconnected, the tube power supply is probably
defective and must be replaced. If the failure disappears after the cable to connector X720 has been
disconnected, then the HV inverter is probably defective and must be replaced. If the cable connected to
X701 is causing the failure, then the master board is
probably defective and must be replaced. If the cable
connected to X706 is causing the failure, then the
problem is either the AC inverter or the tube power
supply. If the cable to connector X723 on the tube
power supply is disconnected and the failure

Tube high voltage, current and mAs values 0
This section describes how to check the X-Ray tube in regard to the:
High voltage, tube current, mAs value with and without AEC and with a small or large
focus.
These values can be checked by measuring HV_ACT/MA_ACT on board D750 and/or by
using the service PC -> SW -> Normal -> Actual values. Only one of them is necessary,
but both methods are described in the following.
Preparation
• Switch the system OFF (e.g., S700 on main input)
• Connect the oscilloscope as follows:
Channel 1 to measurement point HV_ACT (1V=5 kV) on D750
Channel 2 to measurement point MA_ACT (1V= 40 mA) on D750.
• Connect the service PC to the stand.
• Switch the system ON.
• Start the Service program and check in the anode menu whether the tungsten anode is
enabled.
• In the Service program, select Normal->Main menu ->Normal mode->Actual values
Measurement method
The mAs value must be calculated as the product of the tube current and exposure time.
The tube current and the exposure time can be obtained from the oscillograms. The diagram may have glitches, in which case you have to measure the exposure time t1 and t2.
Example:
Fig. 21:
In the figure, the tube current is 150 mA and the exposure time is t1+t2 in seconds.
The mAs is 150mA*(t1+t2)

The Service SW, software system, is used for setting the filament current values.
Work steps
• Connect the Service PC.
• Start the SW.
• Turn the system ON.
• Select Main menu->Configuration->Filament.
Fig. 33: Filament
Indicates the adapted filament current of available anode materials for large and small
focus. Adaptation exposures for the filament current are also made in this menu. Pressing
F3 sets the exposure parameters on the control panel, and subsequently pressing Alt-F6
starts the exposure. Repeat this procedure until the tube current deviation is within ±5%. If
the tube has been replaced, program the filament current value to be 200 mA less than
the value stated in the test certificate as a pre-adjustment. (e.g., if tube value is 6900, program 6700.)
If a new filament current has been entered, you must save the new value (press F2)
before learn filament is performed.
NOTE
The Dynamic Learn Filament may change this adjustment. But the
DLF will learn only when the exposure time is longer than 60 ms.

The filament current values can also be measured on board D750.
FIL_CURR_SET Analog output signal to the generator for setting the magnitude of the filament current. The relation between the filament current and the analog control signal
is1A/V.
FIL_CURR_ACT Analog input signal FIL_CURR_ACT, from the generator, that is proportional to the true filament current. The relation between the filament current and the analog signal is 1A/V.
Independent of the selected focus, the current value is 3.5 A (At test point D750
FIL_CURR_ACT = 3.5 V).
During preparation or exposure, the value is increased to approx. 6.6 A to 6.9 A according
to selected focus.
If no filament current is present, there could be an error on one of the following components:
Filament adaptations are possible only when the detector wing is
selected. "dr" is displayed on the control panel.

General 0
The detector system is an important component of the Mammomat Novation and is key to
image quality. There are 2 detector calibration procedures that should be used if image
artifacts (pixel failures, bad lines, etc.) occur.
• Gain calibration
• Bad pixel mapping
In case of image quality problems, defined test images and files are needed for analysis:
• MPXXXX.map, MPXXXX.cfg, quality.log, MPXXXX.smj
• Test image: 4 cm Plexi, 28 kV, AEC, QC Raw
• Calibration image
These images and files have to be supplied to USC/HSC for support.

Gain calibration 0
A gain calibration should be performed first. If the image artifacts persist, then perform
bad pixel mapping.
Gain calibration
• Creates the offset for each pixel value.
• Filename:<Serial_Number>.map
• If there is no gain calibration file that matches the current array serial number, only cali-
bration scans and service scans are allowed.
Furthermore, the gain calibration procedure must be performed weekly. This procedure
can be performed by the customer or the service engineer.
For SW version VA10x, see the user manual.
Fig. 35: _select_calibration
Eight exposures (accepted) have to be taken.
Work steps for SW VA11x
• Select Examination->Calibration
• Select 28 kV and 250 mAs.
• Select the Anode/Filter combination the customer uses most frequently.
• Mount the collimator-mounted plexi phantom.
• Be sure that no additional objects are in the radiation field.

Bad pixel mapping 0
A new pixel map should be created if excessive pixel dropout occurs repeatedly on
images displayed in the Examination tab card(Fig. 35 / p. 75). The procedure has to be
performed by service and only when a defective line or pixel occurs.
Work steps
• Select Options -> Service -> Local Service
• Enter the service key and press OK.
• Select Acquisition System.
• Select Examination -> Calibration in the menu bar.
• Select Bad Pixel Mapping.
• Select 28 kV and 250 mAs.
• Select the Anode/Filter combination the customer uses most frequently.
• Insert the collimator-mounted plexi phantom.
• One exposure has to be performed.
• Be sure that no additional objects are in the radiation field.
• Once accepted, the defective line(s) or pixel(s) is/are not released again.
If the line/pixel is still visible after bad pixel mapping calibration, try to lower the mAs value
by 50 mAs, e.g., 200 mAs.
NOTE
NOTE
NOTE
NOTE
Bad pixel mapping cannot be repeated without restoring the old
mapping files. Bad pixel mapping is a continuous procedure. Bad
results remain in the mapping file. There is no undo procedure.
Contact the Uptime Support Center.
The bad pixel mapping procedure cannot be performed until the
detector has been powered on for at least one hour to allow it to
warm up.
To go back, the original mapping files from the supplied detector-specific CD must be loaded.
Bad pixels after bad pixel mapping can result from an incorrect adjustment of the collimator setting or wrong X-ray tube settings. In
case of bad pixel(s), also check the collimator adjustment and
X-ray tube settings.

Qualify log 0
Description
An important file of the detector system for image quality is the qualify.log. This provides
information about possible pixel failures in the detector. After every bad pixel mapping,
this file is overwritten with the current data of the detector. This includes possible pixel failures, bad areas or defective lines.
The qualify.log can be found in folder C:\AWS\drul\data or using the Service SW,
Home->Acquisition System->Bad Pixel Mapping.
Images defects in the raw, uncorrected image inside the imageable area must meet the
following performance criteria:
• Not to exceed a total of 2936 defective pixels exclusively or dead lines which corre-
spond to 0.02% of the total amount of pixels.
• Have zero 3x3 pixel areas containing more than 8 defective pixels
• Have zero 5x5 pixel areas containing more than 15 defective pixels.
• Not to exceed a total number of 80 pixel clusters (2x2) where all 4 pixels are defective.
• Not to exceed a total number 20 defective lines.
• Have zero adjacent defective lines (e.g., two defective lines must be separated by at
the least one good line)
The following examples show qualify logs for good and defective detectors:

Checks 0
Check the adjustments 0
For the compression unit to function properly, it is very important that it is adjusted
according to the instructions described in Replacement of Parts, SPB7-250.841.01...
Check the potentiometer R863 (position transducer) 0
• Attach a compression paddle to the compression unit.
• Move the compression paddle up/down.
The display for thickness changes the values during movement.
• Place a defined object thickness onto the detector, e.g.: 40 mm Plexi-phantom.
• Move down the compression paddle by means of the foot switch until the paddle reach-
es the object on the detector.
The value on the thickness display (D803) has to be the same as the object thickness.
If not, adjust the compression unit according to Replacement of Parts, SPB7-250.841.01..
If the potentiometer still does not work properly after the adjustment, the potentiometer
might be defective and need to be replaced.
Check the potentiometer R861 (compression force) 0
• Turn the potentiometer clockwise to a defined position, e.g.: 8 kp (see display on the
lower position of stand).
• Place a scale with a digital display onto the detector and move down the compression
paddle until the movement stops automatically.
• Read the force on the display of the scale. If a deviation >0.3 kp between the values oc-
curs, perform a force adjustment according to Replacement of Parts,
SPB7-250.841.01..
If adjustment is not possible, potentiometer R861 might be defective and need to be
replaced or the compression unit is defective.
Check the movements (up/down) 0
• Press the compression pedals (up/down) for electrical movement of the compression
paddle. The paddle moves up/down.
If electrical movement is not possible, check the power supply:
• Check 14 volt supply on board D802
If this voltage is not present, fuse F1 (5AT) on D805 or F803 might be defective or D805 is
defective or motor of compression unit is defective.

Check the detection of compression paddle. 0
One condition for an exposure release is the detection of a compression paddle. This will
occur by attaching the compression paddle in the guide shaft of the compression unit. The
detection of compression paddles can be checked using the Service SW Stand,
SPB7-250.816.03.. Chapter Service=>Stand test.
Work steps
• Connect service PC and start Service SW of stand, see Software System Stand,
SPB7-250.250.816.03..
Fig. 64: Stand test paddleID
Select Main menu=>Service=>Stand test PaddleID
• Attach a compression paddle to the compression unit and start the test with the service
SW.
A paddle ID will be shown on PC display.
• Repeat this procedure with each compression paddle.

If one of the paddles cannot be detected (ID 99), the paddle might be defective and need
to be replaced.
If none of the paddles can be detected, a problem occurred on the compression unit or
D805 or the ribbon cable between both:
Fig. 65: D805
• Check the ribbon cable between guide shaft and D805 X831(1/Fig. 65 / p. 97). The
connector on the ribbon cable (2/Fig. 65 / p. 97) has to be plugged in so that the "nose"
on the connector (1/Fig. 66 / p. 98), and the pins are visible from above; they are on the
upper side.
