IMS Cable Bear Assy Replacement

Prerequisites

Overview

Procedure

  1. Raise the Table to maximum height.
  2. Move the Cradle and IMS to OUT limit position.
  3. Remove power from Table by turning off 120VAC, Axial Drive and HVDC switches on Service Switch Panel.
  4. Remove the following Table Covers:

    • Top Cover (Right/Left)

    • Front Top Cover

    • Rail Cover (Right/Left)

    • Rear Top Plate

    • IMS Rear Cover

    • IMS Side Cover (Right/Left)

    • Liner Scale Cover

  5. Remove two screws holding the cable duct cover, and remove the cable duct cover from the Table.

    Figure 2. Cable Duct Cover Removal

  6. Remove the Touch Sensor Assy R (it is necessary to disconnect the cable connector), and put it on the Table frame.

  11. Move the IMS so that the cable outlet is behind the rail support.
    note:

    Cable Outlet Cable Outlet There is not enough space between the rail support and the IMS frame for the cable connector to pass through. By moving the cable outlet of the IMS to behind the rail support, the cable connector can be removed through this space.

  15. Verify that the cable connector of the IMS motor does not interfere with IMS/Cradle movement.
  16. Verify that the cables in the cable guide have no deflection and are not twisted.
