TABLE ELECTRICAL ACTUATOR

Prerequisites

Procedure

  1. System Power must be turned OFF. Refer to Lockout / Tagout for System Cabinet PDU Main Breaker..
  2. Disconnect the Table from MR Magnet; take it out from the Magnet room. Refer to TAKE TABLE OUT FROM THE MAGNET ROOM
  3. Remove the scissor covers from the table. SCISSOR COVERS
  4. Assemble lock screw rod to lock position of scissor.

  5. Remove 4 screws of actuator mounting bracket.

    Figure 3. 4 screws

  6. Remove circlips & pin. Remove actuator.

  7. note:

    Before assembling new Actuator assembly, Ensure Actuator restrainer bracket is position to actuator block as shown. also ensure Nut to flush above Actuator restrainer bracket, do not tighten.

    Figure 6.

  8. Assemble pin & circlip for new actuator. In this case, actuator mounting bracket holes will not be aligned with tapped hole in lower base of table.

  9. Notice Image
    • warning
    • FE DO NOT replace actuator FRU kit by screw rode to lift the table during install. This type actuator is designed to support push force only, it is dangerous to use the screw rod to raise the table manually when the actuator is still connected.

    • FE can't Rotate lock screw rod to move tabletop up.
  10. Rotate lock screw rod to move tabletop down and align screw mounting holes.

  11. Assemble actuator mounting screws and tighten.

    Figure 10. Assemble actuator mounting screws

  12. Remove lock screw rod.

    Figure 11. Remove lock screw rod.

  13. Arrest the restrainer block play by tightening the M6 hex head screw
    1. Tighten 2 screws till it butts against actuator top clevis, with this the Gap/play will be arrested between Actuator restrainer block and actuator top clevis.
    2. Above mentioned adjustment are made to ensure sensor rod is both vertical & parallel to rectangular tube during actuator up down motion & arrest sensor rod tilting.
