GE MEDICAL SYSTEMS PROPRIETARY TO GE D IRECTION 2294854-100, REVISION 3 LOGIQ™ 9 PROPRIETARYMANUAL Chapter 7 Diagnostics/Troubleshooting 7-13 Section 7-6 Diagnostics As described in Chapter 5 - Components and Functions (Theory), the service platform uses a web- based user interface (UI) to provide access to common service components. A service dongle (part number 066E0703) is required to access areas proprietary to GE. The Diagnostic home page displays a listing of test categories consisting of Acquisition Diagnostics, I/ O Devices and Common Diagnostics. Expand the desired main category to select groups or individual tests. Figure 7-13 Global Service User Interface Diagnostic Screen

Figure 7-14 shows the top level menu choices under Acquisition Diagnostics. The subheadings and their respective diagnostic/troubleshooting menu choices are called out and described in the sections that follow. Figure 7-14 GE Service Acquisition Diagnostic Menu Selections

The Acquisition Diagnostic menu is structured as follows: 7-7-1 Automatic Troubleshooting - Runs all diagnostics and analyzes the results to isolate to the faulty FRU. - This is the BEST way to diagnose a problem with the system. - Takes less than 6 minutes for all tests to run. - Disconnect all probes from the scanner before executing the Automatic Troubleshooting sequence. The choices for Automatic Troubleshooting, shown in Figure 7-16 on page 7-16 , allows for running all acquisition diagnostics under the selection Troubleshoot All Acquisition Hardware.

GE MEDICAL SYSTEMS PROPRIETARY TO GE D IRECTION 2294854-100, REVISION 3 LOGIQ™ 9 PROPRIETARYMANUAL Chapter 7 Diagnostics/Troubleshooting 7-17 When you select a test to run, like Troubleshoot all Acquisition Hardware , the display changes as shown in Figure 7-18 on page 7-18 . 1.) Instructions Frame - Displays either a test-specific text or the default instructions. 2.) Status Frame - Initially displays the last known status for a selected diagnostic. Once the diagnostic starts, the frame displays the “current” status of all test results. - The Status Frame also contains the user interface elements used for Diagnostic Control and Operator Feedback. 3.) Execute Button - This switch has two modes - each with appropriate text: - Execute - to start the diagnostic - Abort - to stop a diagnostic

Loop Count - This is an editable text field that will only accept numeric values of 4 digits or less. When the switch is configured as an “execute” switch and pressed, the loop count field will be queried to determine the number of times to execute the diagnostic. 5.) Progress Indicator - Displays a graphical progress indicator for the user. 6.) Short Text Message - Displays brief messages about the test’s progress during execution. 7.) Status Frame Background Color - Initially gray, the Status Frame background color changes upon completion of a diagnostic to indicate completion status. - Code Status Fail = Red - Code Status Pass = Green - Code Status neither Pass nor Fail (Example: Aborted) = Gray (default color). 7-7-2 Reliability Testing Overnight relialibility test. - Runs all diagnostics. Logs ALL results. Results accumulate in the log each time the tests are run. The log file continues to grow. NOTE: This is not intended for field service use. Typically a manufacturing test.
