Overview

This section describes subsystem text messages and diagnostic/utility software tools that can help you evaluate OEC UroView® 2800 Table and Generator performance, calibrate the Table and Generator controls, and isolate Table or Generator failures when they occur.

The UtilitySuite (US) software contains many diagnostic programs to aid in servicing the table and generator. The Field Service Engineer should be familiar with operation of the US/RUT software and other diagnostic software for use with a laptop computer.

VFD Messages

The following paragraphs describe all messages that appear on the Vacuum Fluorescent Display (VFD) in the Collimator Housing and on the VFD in the X-ray Control Panel. These two displays are identical and operate in parallel; what you see on one display also appears on the other display.

Each display consists of four lines of 20 characters each, providing a total of 80 characters. The display is luminescent blue and is readable in all lighting conditions except the brightest direct sunlight.

Some VFD messages provide status only. Other VFD messages announce errors or provide warnings, and suggest appropriate remedial action when the system operator can normally solve the problem. More complex errors describe the principal problem, and then display the message, "CALL SERVICE." Most error messages overwrite any routine technique or table position data that may already be present on the VFDs.

Normal Messages

Line 1 of each VFD normally displays Generator technique information.

Lines 2 and 3 of each VFD normally display table position information in latitude and longitude. Consult the Table Operator Manual (00-882096-01) for instructions on how to interpret table position information.

Line 4 of each VFD normally displays Collimator position information, which consists of the collimated rectangle at the plane of the film cassette. Consult the Table Operator Manual for guidance on how to interpret this information.

Table position and technique messages appear on the VFDs until updated by other messages. Routine Information messages appear for a few seconds, and are then replaced by table position and technique data.

Error Messages

When necessary, Table or Generator error messages displace table position information beginning on line 2 of each VFD. Suggested remedial action sometimes appears beginning on line 3 and continues on to line 4 if necessary, displacing Collimator position information. If the message is larger than 20 characters, the display scrolls continuously so you can read the whole message without having to press a key.

Table Error Messages

Generator and Collimator Error Messages

appear until the user corrects the error. Table errors have no associated audible alarms.

also appear on the VFDs. There are six kinds of Generator and Collimator error

messages, some of which generate audible alarms:

Alternating Messages

display alternately with the technique. The message appears for two seconds, and then the technique appears for two seconds. This kind of message appears only when X-rays are not being generated. If the error occurs during X-rays, the current X-ray finishes and then the error message appears.

Timed Messages

display once for two seconds, and then each VFD goes blank. This type of message appears only when X-rays are not being generated. If the error occurs during X-rays, the current X-ray finishes and then the error message appears.

User Action

messages require user intervention, such as pressing or releasing a Table Control Panel key, to clear the message. Software disables X-rays for the duration of the problem. If the error occurs during X-rays, the current X-ray finishes and then the error message appears.

Disable X-ray

messages appear on each VFD until the cause of the error goes away. You cannot clear these messages by pressing a button or key. The Generator cannot produce X-rays when this type of message is present. If the error occurs during X-rays, the current X-ray finishes and then the error message begins.

5. A

Generator System Shutdown

message disables the Generator immediately and completely. Any in-progress X-rays immediately terminate. In most cases, table movement will still be permitted, making it possible to level and unload the table. You must re-boot the system before you can use it again.

Full System Shutdown

messages halt the OEC UroView® 2800 system software, making both Generator operation and

Table movement impossible. You must re-boot the system before you can use it again.

Alphabetic VFD Message Listing

The following table lists all possible VFD messages in alphabetical order with Utility Suite type numbers. (Refer to the Generator Events Log section to access the Generator Events Log.)

If the message is less than 8 characters, it is displayed in the center of the VFD field between any technique values on display. If more than 8 characters, and less than 20, it is displayed as shown. If more than 20 characters, the message will scroll. %S = indicate a displayed number. (Displayed numbers are in decimal notation. Refer to the Generator Error Messages portion of this manual section for Hexadecimal equivalents.

Utility Suite Type numbers 30001 through 30043 are displayed on line 1, Generator Errors (unless otherwise noted); 30044 through 30060 on Line 2, Table Errors. Types 30061 through 30089 are Table Information messages.

System Events Log Reporting

The OEC UroView® System Events Log obtains an error message from the Generator and adds the following information:

1. System time: date and time when the error occurred. The system time is different than the Generator time

2. System Phase. State of the system where the error occurred.

3. Error message (refer to the Alphabetical VFD Message listings in this manual section).

Whenever a generator error is logged in the System Events Log file and displayed on the operator console (or workstation), the generator events log upload functionality is available for more detailed error information. This function must be performed from the operator console (or workstation) or by uploading the file into a laptop and opening it with UtilitySuite.

Having this information, look at the generator trouble-shooting table to find the FRU to replace.

The system logs errors and uses them to determine the next acquisition mode (degraded or not). The generator error log file contains a maximum of 64 log entries.

Generator Errors

Power-on Diagnostics

At power up, the kV Control PCB performs its own initialization, checks its memory integrity and starts the communication with its peripherals and the system; Communication is permanently checked afterwards. Then it initializes the Rotation PCB and Heater PCB with their respective database parameters and loads kV Control FPGA.

Eight LEDs (S7 - S0) on the kV Control PCB show the software status. (Refer to the Reading kV Control PCB Power-on Diagnostic LEDs in this manual section.)

During power on, the Heater PCB and the Rotation PCB CPU’s initialize themselves and check their memory integrity and hardware. If a problem is encountered, an error is reported to the kV Control PCB.

Live Diagnostics

Diagnostic faults are reported using an error code and associated message to the error log. Some are straight forward and others must be researched to find their root cause. Refer to the listing in the Alphabetic VFD Message Listing inthis manual section for causes and recommended action.

Diagnostics run separately:

1) Heating without HV nor rotation

2) Rotation without HV nor filament

3) Inverter gate command diagnostic

4) Inverter in Short circuit diagnostic

5) No load HV without anode rotation nor filament heating

The Generator performs self-calibrations initiated by commands via the CAN Bus serial port. Various data is downloaded into the Generator including, but not limited to, AEC tables, X-ray Tube data, etc.

When an error is detected, it is sent to the system and is logged in parallel in the generator error log file.

The following is a general list of generator errors and their error codes. As a troubleshooting aid, a detailed listing follows this table with troubleshooting suggestions for many of the error codes.

Heating without HV nor Rotation Diagnostic

Purpose :

The purpose of this test is to drive the heater inverter(s) on both filaments and all the tubes connected to the Generator in order to identify a faulty heater FRU or a wrong connection between heater board, HV Tank and tube(s).

Pre-requisites :

Note to the error 0324H:

The generator sends only one message of error for all the arcs (0324H) at the end of the exposure. During the same exposure, there may have been different kind of arcs.

In the data of this error, we can distinguish between the different arcs:

1. Arc in anode side

2. Arc in cathode side

4. Arc in both sides

8. kV regulation error.

For an exposure with anode and both sides arc, the data will be “5”

These data can be displayed in the workstation in decimal or in hexadecimal base.
