What This Guide Helps With
Identifies causes of non-functioning Trendelenburg or lateral tilt, including control, actuator, safety lock, and load issues before assuming internal failure.
Step-by-Step Troubleshooting
Ensure Patient Safety
- Confirm the table is not supporting a patient. If in use, safely transfer the patient to another table before troubleshooting.
Check Power Source
- Verify the table is plugged in and the circuit is live. Check for tripped breakers or GFCI outlets. Without proper power, tilt motors will not operate.
Inspect Hand Control / Pendant
- Ensure the hand control or pendant is connected securely. Operate other movements (height, longitudinal) to verify responsiveness. If the hand control is unresponsive, this may be the cause.
Examine Foot Control (If Equipped)
- Some tilt functions may be activated via foot control. Confirm foot pedal is fully engaged and connections are secure.
Check Safety Locks / Brakes
- Verify that all brakes or locks are disengaged. Tilt functions are often inhibited when brakes are engaged.
Observe Table Load and Balance
- Remove any heavy attachments or accessories. Tilt motors may fail to operate under excessive load or if the table is unbalanced.
Listen for Motor Response
- While commanding a tilt, listen for motor noise. No sound may indicate electrical or control issues; abnormal sounds may indicate mechanical obstruction.
Inspect Wiring and Actuators (External Checks Only)
- Look for visible pinched or disconnected cables at the base of the table. Ensure actuator rods or tilt mechanisms are free of obstruction.
Test with Minimal Load
- Operate Trendelenburg and lateral tilt without patient or heavy attachments. Functioning with minimal load may indicate a load or obstruction issue rather than internal motor failure.
If the Problem Persists
- External causes have been ruled out.
- Remove the table from service and label as Out of Service.
- Send for bench evaluation or authorized repair.
- Knowing when to stop prevents patient risk and further damage.
Clinical Use Tip
- Never attempt tilt adjustments with a patient on the table if function is impaired.
- Always move the patient to a stable table first.
- Verify all staff are aware the table is non-functional.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Trendelenburg and lateral tilt do not respond to hand or foot controls."
Cause
What was observed during troubleshooting.
Example:
"Tilt motors did not respond; external inspection revealed no loose connections or obstructions."
Resolution
What action was taken.
Example:
"Table removed from service and labeled Out of Service for repair."
Helpful Details to Include (If Known)
- Outlet tested and confirmed live
- Hand and foot controls tested
- Brakes/locks status verified
- Table load minimized for test
- No abnormal sounds or heat detected
- Final status: Out of Service
Final Thought
Patient safety must guide every troubleshooting step. Systematic, logical checks allow you to identify external issues without risking patient or equipment. Proper documentation ensures clear communication and effective repair workflow.
That is successful troubleshooting.
