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).
- Expected: No power, intermittent power, or partial function loss confirmed.
- Why it matters: Helps determine if issue is total power loss or function-specific.
Check Power Source (Outlet)
- Confirm the table is plugged into a known working outlet. Test with another device.
- Expected: Outlet provides stable power.
- Why it matters: Facility power issues are the most common and easiest to correct.
- If no power → restore power and retest
- If power is good → continue
Inspect Power Cord and Plug
- Check entire cord for cuts, fraying, crushed sections, or loose plug.
- Expected: Cord is intact and securely connected.
- Why it matters: Damaged cords can cause intermittent or complete power loss.
- If damaged → remove from service and replace cord
- If intact → continue
Check Power Entry Point on Table
- Inspect where the power cord enters the table base for looseness or strain.
- Gently move the cord while attempting operation.
- Expected: No intermittent power when cord is moved.
- Why it matters: Internal strain at entry point is a common failure area.
- If intermittent → likely wiring/connection issue → escalate
Verify Control Activation
- Attempt to operate the table using the hand control or footswitch.
- Expected: No response or inconsistent response.
- Why it matters: Confirms power is not reaching control circuits or actuators.
- If controls light up but no movement → possible internal issue
- If no response at all → continue
Check for Indicators (if applicable)
- Look for any indicator lights, sounds, or signs of power when plugged in.
- Expected: No lights or inconsistent indicators.
- Why it matters: Helps determine if power is reaching internal components at all.
Inspect External Connections and Accessories
- If the unit has detachable controls or accessories, reseat connections.
- Expected: Secure connections with no looseness.
- Why it matters: Loose connections can interrupt power distribution.
Cycle Power
- Unplug the table, wait 30–60 seconds, and plug back in.
- Expected: Table resets and powers on normally.
- Why it matters: Can clear minor electrical faults or protection states.
- If resolved → return to service
- If not → continue
If the Problem Persists
All common external causes have been ruled out. The issue is likely internal (power supply, wiring harness, or internal connections).
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 reflects proper troubleshooting practice.
Clinical Use Tip
Never troubleshoot power-related issues while a patient is on the table. Always transfer the patient first to avoid unexpected movement or loss of positioning.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Exam table not powering on or intermittently losing power during use."
Cause
What was observed during troubleshooting.
Example:
"Damaged power cord near base entry point causing intermittent power loss."
Resolution
What action was taken.
Example:
"Removed from service and replaced power cord; verified proper operation."
Helpful Details to Include (If Known)
- Outlet tested and verified
- Power cord condition
- Indicator lights present or absent
- Intermittent behavior when cord moved
- Control response status
- Any unusual sounds, smell, or heat
- Final device status (in service / out of service)
Final Thought
Effective troubleshooting starts with simple, external checks and progresses logically. Power issues are often straightforward, but knowing when to escalate protects both the patient and the equipment. Clear documentation ensures continuity and supports long-term reliability.
That is successful troubleshooting.
