This adjustment is for the mechanical interlock which prevents the Patient Table from being undocked or lowered while the Cradle is in the magnet bore.

Procedure

  1. Undock the Table.
  2. Fasten the Upper Bellows in the up position and remove both the Lower Base Side Cover and the Front Base Cover from the Patient Table. See the Patient Table Upper Bellows and Lower Base Side Cover Removal document for details.
  3. Raise the table to its maximum height.
    • warning
    • Risk of personal injury
    • Severe injury can occur if the table is accidentally lowered during maintenance.
    • When doing maintenance with the table in the Up position, make sure the lock bar is safely engaged.
  4. Lower the table lock safety bar.

  5. Lower the table and verify that all of the table top's weight is resting on the safety bar.
  6. With Cradle in NOT HOME position (Cradle off the flipper and in up position), check the interlock mechanisms for tolerances. To make adjustments, do one of the following:
    1. 1/16 to 1/32 inch (1.59 to 0.79 mm) gap - Adjust angle between link and bracket with set screws.

    2. 1/8 inch (3.18 mm) gap - Loosen lock nut and tighten or loosen the cable adjustment screw to achieve the proper gap. Tighten lock nut.

    note: If the adjustment screw does not provide enough range for adjustment, coarse adjustment may be made to the cable length where the cable end is clamped into actuator bracket. Fine adjustment will be required after performing a coarse adjustment.
  7. Raise the table lock safety bar.

Finalization

With the Cradle fully into the bore, ensure that the table down pedals do not allow the Table to go down. Use both the table down pedal from the Table and the dock. If the Table does go down, please perform the adjustment procedures again.
