About this task

Overview

The Motor On actuation switch in the dock assembly should be adjusted so it is activated when the Table Up foot pedal is pressed approximately 3/4 of its total length of travel. This is factory adjusted; however, it is possible to adjust the position of the Motor On switch in the field to maintain the proper actuation level.

Procedure

  1. Remove the dock from the magnet room. Refer to Dock Removal and Reinstallation.
  2. Using a 3/4 inch wrench, remove four bolts (2 on each side) to unfasten the dock cover from the dock base. See illustration below.
    Figure 1. Dock Brackets
  3. While removing the dock cover disconnect the switch connector.
  4. Carefully remove the dock cover from the dock base and then turn the dock cover upside down.
    Note:

    Use care to ensure the top of the cover is not scratched. Lay down a cloth before setting the cover on the floor.

  5. Loosen two mounting screws securing Motor On switch to side of dock assembly.
  6. Adjust Motor On switch position so it is activated (clicks) when the Table Up foot pedal is pressed approximately 3/4 of its total length of travel.
  7. After adjustment is complete, tighten two mounting screws.
  8. Connect the switch connector inside the main dock cover.
  9. Replace main dock cover by securing four mounting bolts.
  10. Reinstall the dock. Refer to Dock Removal and Reinstallation.

Finalization

  1. Ensure that dock Motor On switch operates properly when Table Up pedal is pressed.
  2. Verify that cradle travel into the bore is still OK. If not, refer to Dock Adjustments and perform recentering procedure for the dock/table.
  3. Perform a “good-bye” or validation scan.
