What This Guide Helps With
Table not powering on, intermittent operation, or loss of functions caused by external power issues, cord problems, or connection faults.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the table from active patient use before troubleshooting.
- Expected: Patient safely relocated to another table.
- Why it matters: Power instability can cause unexpected movement or loss of positioning.
Verify the Reported Issue
- Attempt to power on the table and operate all functions (hi-lo, backrest, drawer heater if equipped).
- Expected: No power, intermittent power, or partial function loss observed.
- Why it matters: Confirms whether the issue is total power failure or limited to specific components.
Check Power Source (Outlet)
- Ensure the table is plugged into a known working outlet. Test with another device.
- Expected: Outlet provides consistent power.
- Why it matters: Facility power issues are the most common and easiest to resolve.
- If no power → restore outlet power and retest
- If outlet is good → continue
Inspect Power Cord and Plug
- Check the entire power cord for cuts, fraying, kinks, or exposed wiring. Inspect plug blades.
- Expected: Cord and plug intact with no damage.
- Why it matters: Damaged cords can cause intermittent or complete loss of power.
- If damaged → remove from service and replace cord
Verify Power Connection at Table Entry Point
- Inspect where the power cord enters the table base for looseness or strain.
- Expected: Secure connection with no movement or damage.
- Why it matters: Internal wiring issues often begin at high-stress entry points.
- If loose → secure connection and retest
Check for Indicator Lights or Audible Signs
- Look for any LEDs, relay clicks, or signs of power when attempting operation.
- Expected: Indicators respond when powered.
- Why it matters: Helps determine if power is reaching the system but not being distributed.
- No indicators → possible upstream power issue
- Indicators present but no function → possible internal distribution issue
Inspect External Accessories (if equipped)
- Disconnect any accessories (drawer heater, outlets, attachments) and retest table operation.
- Expected: Table functions normally with accessories removed.
- Why it matters: A faulty accessory can interrupt or overload the power circuit.
- If resolved → isolate faulty accessory
Check Control Inputs
- Attempt operation using both hand and foot controls (if equipped).
- Expected: Consistent response from at least one control.
- Why it matters: A failed control can mimic a power issue.
- If one control works → replace faulty control
- If neither works → continue
Power Cycle the Table
- Unplug the table for 30–60 seconds, then reconnect and retest.
- Expected: Table resets and functions normally.
- Why it matters: Clears minor electrical faults or control lockups.
- If resolved → return to service
If the Problem Persists
If all external power sources, cords, connections, and accessories have been verified, the issue is likely internal (power supply, wiring harness, or control board).
Remove the table from service, label it Out of Service, and send for repair or bench evaluation.
Knowing when to stop prevents unnecessary risk and ensures proper repair.
Clinical Use Tip
Never troubleshoot power-related issues while a patient is on the table. Always transfer the patient before evaluating electrical faults.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Exam table not powering on; no movement from controls."
Cause
What was observed during troubleshooting.
Example:
"Failed internal power supply after external power and cord verified functional."
Resolution
What action was taken.
Example:
"Removed table from service and sent to vendor for power supply replacement."
Helpful Details to Include (If Known)
- Outlet tested and verified
- Power cord condition
- Indicator light behavior
- Accessory involvement (drawer heater, outlets)
- Control response (hand/foot)
- Any unusual sounds, heat, or smell
- Final device status (removed from service or operational)
Final Thought
Effective troubleshooting starts with simple, external checks and progresses logically. Power issues are often external, but recognizing when the fault is internal protects both patients and equipment. Proper documentation and timely escalation are key to maintaining safe and reliable operation.
That is successful troubleshooting.
