Table 4 Safety
  • danger
  • FATAL ELECTRIC SHOCK HAZARD!!
  • TO PREVENT FATAL ELECTRIC SHOCK, DISCONNECT POWER FROM THE PDU BEFORE YOU PERFORM THE FOLLOWING PROCEDURES.
  • PERFORM LOCKOUT / TAGOUT PROCEDURE PER GE OSHA LOCKOUT / TAGOUT REQUIREMENTS LISTED IN THE FIELD SERVICE EHS MANUAL & TRAINING 2000 P/N 2135387-200.
  • warning
  • POSSIBLE PERSONAL INJURY!
  • THIS PROCEDURE REQUIRES movement OF FERROUS MATERIAL IN CLOSE PROXIMITY TO THE MAGNET
  • TWO FIELD ENGINEERS ARE REQUIRED AT ALL TIMES.
  • warning
  • Personal injury and equipment damage
  • Strong Magnetic Field
  • When servicing any magnetic equipment, it is critically important that the service engineer consciously plan the path to be taken when moving highly ferrous devices in the magnet environment. the path should be as far from the magnet as practical.
  • Safety Requirements
  • The service path must allow for the dock to be moved along the ground a distance equal to that of the distance between the magnet and the foot-end of the patient table prior to being lifted vertically.
  • Two (2) MR safety trained personnel must be present at all times when servicing highly ferrous devices in the areas of magnetic fields.
  • When planning a service path, it is critical that the path be clear and sufficiently wide. Ensure that there are no trip hazards, obstacles, clutter, slippery surfaces or other items even partially restricting the path. If there are portable obstacles in a path, remove them from the area and replace them after the service action is completed. It is required to walk the path prior to beginning service to ensure that there is sufficient space through which to pass for yourself and the object being serviced.

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 and perform recentering procedure for the dock/table.
  3. Perform a “good-bye” or validation scan.
