What This Guide Helps With
Error: MOTOR DEF indicating loss of sliding motor control, resulting in inability to move the tabletop longitudinally.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the table from active patient use.
- Transfer the patient to a safe surface if necessary.
Verify the Reported Error and Behavior
- Confirm “MOTOR DEF” is displayed.
- Attempt sliding (longitudinal movement) using the hand control.
- Observe if no movement or motor sound is present.
- Check if other table functions operate normally.
Check Hand Control Function
- Test other movements (height, tilt, trendelenburg).
- Try an alternate control if available.
Inspect Cables and Connections
- Check for loose or damaged cables.
- Ensure all connectors are fully seated.
Check for Mechanical Obstruction
- Inspect sliding track for debris or damage.
- Ensure nothing is blocking movement.
Verify Power Status
- Confirm connection to mains power or adequate battery charge.
- Check for additional power-related errors.
Isolate the Issue
- If only sliding fails, issue is isolated to motor or control circuit.
- No sound or response indicates motor/control failure.
If the Problem Persists
External causes have been ruled out. Persistent MOTOR DEF indicates likely failure of the sliding motor or associated internal components.
- Remove the table from service
- Label Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot on an active patient. Move the patient to a backup device before attempting diagnosis or repair.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Table displaying MOTOR DEF error; sliding function inoperative with no motor response."
Cause
What was observed during troubleshooting.
Example:
"Sliding motor assembly failure suspected after controls, cables, obstruction, and power were verified normal."
Resolution
What action was taken.
Example:
"Removed from service and sent for repair. Sliding board/motor assembly requires replacement."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Motor-related errors like MOTOR DEF should always be approached by ruling out simple external causes first. Once isolated, prompt escalation ensures patient safety and prevents further system damage. Proper documentation supports efficient repair and tracking.
That is successful troubleshooting.
