CFTEST1 and CFTEST2 are analog test test signals, CFTEST3 ... COLORPA CO LORPAT T are digital test test data. Hints for troubleshooting with the colour flow test patterns: •
•
CFTEST1 CF TEST1 and CFTEST2 are inserted the very ve ry beginning of the c colour olour flow Therefore, if CFTEST1 and CF CFTEST2 TEST2 at produce correct test patterns, it can be module. assumed that the th e complete colour flow module is i s operating correctly. If one test pattern fails, but the next pattern down the chain cha in is correct, the error must be in the hardware between the two insertion points. point s. (This does not strictly apply for CFTEST9 and COLORPAT COLORPA T, which are generated outside the colour flow flo w module.)
If one test pattern fails, but the next one is correct: •
The signals and data for CFTEST1 ... CFTEST4 CFTEST4 are generated o on n the A50 Discrimi Discriminator-2 nator-2 itself, the first board of the chain.
Í •
The data for CFTEST5 CFTEST5 is generated on the A63 Correlator-2 itsel itself. f.
Í •
If CFTEST5 fails and CFTEST9 is correct, the error must be on the A63 Correlator-2.
The data for CFTEST9 is generated on the A69 Administrator. Adm inistrator.
Í •
If CFTEST1 ... CFTEST4 CFTEST4 fail and CFTEST5 is correct, the error must be on o n the A50 Discrimi Discriminato nator-2 r-2..
If CFTEST9 fails and COLORPAT is correct, the error is probably on the A53 Triplexer-2; but it may also be on the output of the A63 Correlator-2, or on the A69 Administrator.
The data for COLORPA CO LORPAT T is also generated on the A69 Administrator Administrato r.
Í
If COLORPAT fails, the error is probably on the A54 Reflector; but it may also be on the A53 Triplexer-2, or on the A69 Administrator.

Before you invoke the colour flow test patterns, you must perform the following steps in order to obtain correct results: •
Enter the troubleshooting password.
•
Select any array transducer. Because the colour flow test patterns p atterns do not work with all simulated transducers, we recommend to use a real transducer connected to the system.
•
Select B-mode, and set B gain and all DGC DGC slide slide pots to maximum: the image shape is visible.
•
Rotate the Depth Depth control control clockwise and maximize the depth.
•
Press the C control: The green border of the ROI (region of interest) appears.
•
Rotate the C control clockwise and set the C gain to maximum: ma ximum: colour noise (red and blue speckles) appears randomly in the ROI.
•
Set Window Set Window to to „Pos“, and move the ROI with the trackball trackbal l into the upper left corner of the image.
•
Set Window Set Window to to „Size“, and maximize the ROI with the trackball trac kball towards the lower right corner of the image: the near field continues to show the B/W reflections (depending on the B gain setting), while the middle and far field is filled with moving colour noise.

5. Diagnostics 5.1
Introduction
In addition to the Troubleshooting Commands described in section 4, the SONOLINE Versa Plus system provides diagnostic test software which allows you to collect information about the status of the system hardware. Only authorized service personnel has access to the diagnostic test software through a special "service menu password" (see section 4.2, Troubleshooting Passwords )).. There are three different types of diagnostics: •
Start-Up Diagnostics These are automatically executed exec uted when the system is powered on (e.g. polling the board boa rd revisions).
•
Background Diagnostics These are executed regularly while the system is operating (e.g. monitoring the power supply voltages), except while a preset menu is displayed.
Both the Start-Up and Background Diagnostics are normally "invisible" to the user. An error message is displayed only if the diagnostic software detects an error in the system. •
Operator Diagnostics These are manually started from the keyboard.
In all three cases, the test results are written into the "Service Support Data Base" in the SONOLINE Versa Plus system for later use (see next section). In the initial customer release, not all planned features of the diagnostic software are available yet.

The operating time is counted in the background, but the time display is not updated automatically while the menu is displayed. Pressing Set activates a cursor that allows you to manually change the operating time. Normally the Set activates operating time should not be changed manually. Loading a new system software does not reset the operating time.
Key Sequence Log This menu displays the keys that had been pressed before the Key Sequence Log menu had been entered. The menu can be useful in determining the user’s key sequence before a system malfunction had occurred. This may be particularly important if the system "locks up" due to a software bug which only occurs after a certain key sequence. Keystrokes are logged even while a menu is displayed. The last entry will always be SET be SET (pressing Set Set had had invoked the Key Sequence Log).

Change Language This menu is not really a troubleshooting tool: It allows you to change the language of the screen display by re-loading language data from a diskette. If there is a diskette with data for only one language in the floppy disk drive, that data is loaded into the system automatically. If there is a diskette with data for more than one language in the floppy disk drive, a selection menu will be displayed on the screen, and the needed language can be selected with the trackball. After loading new language data, the diagnostics menus remain in English.

8. LEDs LEDs an and d Test est Poin Points ts 8.1
Introduction
The boards of the SONOLINE Versa Plus imaging system contain LEDs and test points. Please be aware that the LED and test point information shown on the following pages is valid for the indicated board revisions. On newer board revisions the placement and meaning of the LEDs and test points may differ. LEDs •
In this document, only the three LED LE D states "ON", "OFF" and "Flas "Flashing" hing" are used. There is no distinction made between LEDs driven by a constant voltage level, level , and LEDs that are driven by a fast pulse sequence, unless the pulse frequency is so low that a "flashing" effect is visible.
•
The state of some LEDs may change - dur during ing power-u power-up p or or rreset eset - while switching from (the "standard") B-mode to M-, BM-, Doppler-, BD- or BMD-mode. The following pages usually describe only the "stable" "stabl e" LED states within a defined mode of operation.
•
Please be aware that the LED information shown on the following pages is just one of several troubleshooting tools. The behaviour behavio ur of some LEDs can depend on a wide variety of system settings, so that the LED information informa tion may not be used as the only indicator indic ator to identify a defective board.
Test Points •
Only those test points poin ts which are relevant for the field service are show shown. n. These test points are usually located on the outer ou ter edge of the boards, and can be accessed wit without hout an extender board.
•
Most of the test points not described describ ed here are for debugging purposes at the manufac manufacturer. turer.

9. Mini Minimu mum m Con Config figur urat ation ion Ins Insta talla llatio tion n If somewhere in the system there is a fault which cannot be located immediately, the "Minimum Configuration" Installation method may help you to find the faulty board: •
Pull out all boards in the system syst em from their connectors, except for - boards that cannot be removed removed easily: easily: A10 Operator, A21 Binder, A28 Isolator, and A35 Allocator, and - a minimum config configuration uration of boards boards that are needed needed to make the system system respond (see Step Step 1 below).
•
Add the other boards as described below, be low, one by one, and check the system response. If the system does not respond as described, des cribed, the board that was added last is prob probably ably the faulty board.
Please keep in mind that the following list of checks cannot be complete, and there may be faults that may not be detected by this method. The optional boards A66 Stabilizer (TEE transducer interface) and A67 Provider (optically isolated RS-232C ports) are not covered in this chapter. Turn power off before inserting or removing any board!
Board Bo ards s in in the the syste system m
When When board board(s (s)) are are okay okay th the e syst system em will will respo respond nd as fo follo llows ws::
Step 1: Minimum Configuration •
A62 Commander
•
after turning power on, all keys are illuminated illumin ated for a short time
•
A69 Administrator
•
after the system has booted up, the LED of the B-mode B -mode control is illuminated, and the LCD is active
•
pressing any key produces the usual "click"
•
all B- and M-mode controls (e.g. B+B) respond respo nd correctly (i.e. their lamps are illuminated)
•
upon pressing any LCD key, the annotation changes accordingly
Step 2: External video signal • after pressing the Video I/O key, add: I/O key, an external video signal (e.g. from a VCR) is displayed correctly • A58 Translator-2
