What This Guide Helps With
Identifies causes of no power or intermittent shutdowns, including power supply, battery, and connection issues before assuming internal failure.
Step-by-Step Troubleshooting
Ensure Patient Safety
- Confirm the table is not in use with a patient.
- If in use, safely transfer the patient to another table before proceeding.
Verify AC Power Source
- Check that the table is plugged into a known working outlet.
- Test the outlet with another device.
- Why: Loss of facility power is a common and easily overlooked cause.
Inspect Power Cord and Connections
- Ensure the power cord is fully seated at both the wall and table connection point.
- Look for visible damage, fraying, or bent pins.
- If damage is found, remove from service.
Check Power Indicator Lights
- Observe for any LEDs or indicators on the base or control panel.
- No lights → possible power supply issue
- Intermittent lights → possible loose connection or failing battery
Attempt Power On Using Multiple Controls
- Try powering on using:
- Main control panel
- Hand pendant (if equipped)
- Why: Helps rule out a faulty control interface.
Check Battery Status (If Equipped)
- Disconnect AC power and attempt to power the table using battery only.
- Then reconnect AC power and observe charging indicators.
- Expected Outcome:
- No battery function → battery may be depleted or failed
- Intermittent operation → battery may not be holding charge
Inspect Battery Compartment (External Check Only)
- If accessible without disassembly, confirm battery is properly seated.
- Look for corrosion or loose connections.
- Do not open sealed compartments.
Cycle Power
- Disconnect from AC power for 30–60 seconds, then reconnect and attempt restart.
- Why: Resets minor control or power module faults.
Check for Environmental or Use Factors
- Ask staff if power loss occurs during movement or positioning.
- If yes → possible internal cable strain or loose connection
- If random → possible power module or battery issue
Swap Power Cord (If Compatible and Available)
- Use a known good cord to rule out cord failure.
- Why: Damaged cords can cause intermittent power loss.
If the Problem Persists
All common external causes have been ruled out. The issue is likely internal, such as a failing power supply, internal wiring fault, or battery system failure.
Remove the table from service, label it Out of Service, and send for repair or bench evaluation.
Do not attempt internal repairs in the clinical environment. Knowing when to stop is proper troubleshooting.
Clinical Use Tip
Never troubleshoot power issues while a patient is on the table. Always transfer the patient first to avoid loss of positioning or injury risk.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Surgical table would not power on and intermittently shut off during use."
Cause
What was observed during troubleshooting.
Example:
"Failed internal battery not holding charge, causing intermittent power loss when AC connection fluctuated."
Resolution
What action was taken.
Example:
"Removed table from service and sent to vendor for battery replacement and power system evaluation."
Helpful Details to Include (If Known)
- Outlet tested and verified
- Power cord inspected/swapped
- Indicator light behavior noted
- Battery function tested
- Any intermittent movement-related power loss
- Final device status (removed from service)
Final Thought
Power issues should always be approached from the simplest external causes first. Ensuring stable power and battery function protects patient safety and prevents unnecessary downtime. Escalation after ruling out external factors is the correct and professional approach.
That is successful troubleshooting.
