The MCR tool helps isolate failures within the MCR chain. In order to rule out potential failures with the system cabinet or the 8-channel switch, it is recommended that you begin by running the Mega Switch diag and the syscab loopback test diag prior to running the MCR tool.

About this task

Overview

The Multicoil Receive Chain Tool provides a means of diagnosing problems in Multicoil Receive (MCR) chain hardware, without use of coils. The tool sends signals down the individual paths to isolate specific channels in the receive chain. The tool’s Graphical User Interface (GUI) guides the user through the various steps involved in running the tool and troubleshooting the problem. The GUI has built-in instructions and detailed setup instructions, troubleshooting flowcharts and documents that will help facilitate rapid diagnosis of the problem. There are two levels of tests that can be run using the MCR III tool: Default and Individual. Once you've decided to use MCR III tool, determine which level of test your situation requires. The default and port-specific levels of tests offer increased user-friendly automation that is been omitted from the individual tests by design. Therefore, it is imperative to identify which level of tests you need to perform and then follow the instructions for that specific level.

  • Port A Default Tests

    • This test must be passed during the MR installation.

    • In most scenarios, this is the first test that should be run when using the MCR tool.

    • If this test fails, individual tests can be run to further isolate the failing component.

  • Port A Individual Tests

    • These tests are designed to run after the default test indicates a failure.

  • Uno Coil Test For Fixed Table

    • This test must be passed during the MR installation.

MCR III tool for Optima MR360 and Brivo MR355 consist of following two Tests. For Detachable Table, perform Port A Default Test during Installation. For Fixed Table, perform both Port A Default Test and express PA Coil Test during Installation.

MCR III Port A Test

Hardware setup

Procedure

  1. Port A's path travels through the hypertronics port, cable path, and the preamps within the Multi-coil Interface Box before going to the Mega-switch.
    Figure 1. MCR III Port A Testing
  2. Move the platform so the LPCA port are accessible.
    Figure 2. LPCA Hypertronics Ports
  3. Connect MCR3 Tool to the Port A of LPCA.

RUN MCR test

Procedure

  1. Note:

    If MCR III tool is invoked from Installation and Calibration Wizard (ICW), the following menu is automatically shown. Please follow this procedure even if the screen seems slightly different for ICW Installation Mode.

    Figure 3. MCR III tool
    If Running from the Common Service Desktop, click on the Diagnostics Tab and then, on the left pane, System Function->RF->Multi-Coil Receive III Diag.
    Figure 4. MCR III Home Page

    The MCR interface is designed to automatically display tools that are pertinent to your system.

  2. Verify that the MCR tool is connected to the port A (see Figure 2).
  3. Select the Port A and then click Run. This test includes the following two tests.
    1. With preamps OFF (Port A).
    2. With preamps ON (Port A).
    Note:

    The Default tests will automatically run all the individual Port A tests.

    The individual tests are primarily designed to allow field engineers to hammer a specific portion of the MCR chain.

    Figure 5. Port A Test
  4. If you want to run the individual test, select one you want to run. (With preamps OFF (Port A) or With Preamps ON).
  5. If the MCR tool reports a failure (designated by red text in the results, for example,Figure 6), see MCR III Chain Tool Troubleshooting for troubleshooting.

MCR III Express PA Coil Test for Fixed Table

Hardware Setup

Procedure

  1. Remove 3 Port A’s connectors from MCR3 Tool.
    Figure 7. Disconnect 3 Connectors from MCR3 tool
  2. Connect DC cable ASSY and RF cable ASSY to MCR3 Tool as Figure 8.
    Figure 8. Connect the DC cable assy and RF cable assy to MCR3 tool
  3. Move the cradle inside the bore until free from the side guards.

    Release the cradle from the LPCA.

    Figure 9. Release the cradle
  4. Place the thin foam underneath the cradle front to prevent bridge and cradle from scratching.
  5. Lift the cradle at the handle by 1 hand and use the other hand to insert the foam.
    Figure 10. insert the foam
    Note:

    Foam is stored in Cart during Installation.

    Figure 11. Foam Location
  6. Access to the Connectors below the Cradle.
    Figure 12. Access to the Connectors
  7. Remove RF & DC connector from the socket mounted on the cradle:
    Figure 13. Remove RF & DC connector
  8. Remove cable track from cradle.
    Figure 14. Remove Cable Trak
  9. Remove PADs and restore the Cradle position.
  10. Connect RF & DC cables.UNO PA coil RF &DC cable ASSY and MCR III tool. SeeFigure 15orFigure 16

RUN MCR test

Procedure

  1. Go to the Service Desktop and start the Common Service Browser if it is not already running.
  2. Click on the Diagnostics Tab and then, on the left pane, System Function->RF->Multi-Coil Receive III Diag.
    Figure 17. MCR III Home Page

    The MCR interface is designed to automatically display tools that are pertinent to your system.

  3. Select the express PA Coil-Cradle and then click Run.

    Figure 19. Passed Result
  4. If the MCR tool reports a failure (designated by red text in the results, for example,Figure 20), see MCR III Chain Tool Troubleshooting
    Figure 20. Failed Result
  5. Restore the PA Coil as it was by reverse order.
