What This Guide Helps With
This guide assists Clinical Engineering in troubleshooting a Skytron 6500 Series surgical table that will not power on. Symptoms may include:
- No indicator lights when attempting to turn on
- No response from hand or foot controls
- Table completely unresponsive
Focus is on external, verifiable checks before escalating for repair, keeping patient safety as the highest priority.
Step-by-Step Troubleshooting
Verify Power Source
- Ensure the table is plugged into a known working outlet.
- Test the outlet with a voltmeter or another device.
Reason: A dead or tripped outlet is a common, easily fixable cause.
Check Circuit Breakers and Fuses
- Inspect wall or table circuit breakers. Reset if tripped.
- Check table-specific fuses if accessible externally.
Reason: Overcurrent protection may prevent the table from powering.
Inspect Power Cord
- Look for cuts, fraying, or loose connections at both ends.
- Swap with a known good power cord if available.
Reason: Damaged cords can prevent power without visible signs on the table.
Examine Main Power Switch
- Ensure the main power switch on the table base is turned on.
- Toggle it off and on again.
Reason: Sometimes the switch may not fully engage.
Check Battery Backup (If Equipped)
- Some Skytron 6500 tables have internal batteries for limited operation.
- Confirm battery is seated and charged, or bypass if external AC power is available.
Reason: A dead backup battery may prevent control electronics from booting.
Observe Indicator Lights
- Look for any LEDs on the table base or pendant.
- No lights often indicate power not reaching internal electronics.
If the Problem Persists
Common external causes have been ruled out. The issue is likely internal (power supply, controller board, or internal wiring).
- Remove the table from service
- Label as “Out of Service”
- Send for vendor repair or bench evaluation
Clinical Engineering principle: knowing when to stop is proper troubleshooting and ensures patient safety.
Clinical Use Tip
Never troubleshoot the table while a patient is on it. Move the patient to a functional table first. Only perform checks on a powered-off and safe device.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Table will not power on; no lights or response from controls.”
Cause
What was observed during troubleshooting.
Example:
“Verified outlet functional, power cord intact, circuit breakers reset; table remained unresponsive.”
Resolution
What action was taken.
Example:
“Table removed from service, labeled Out of Service, sent for vendor repair.”
Helpful Details to Include
- Outlet voltage tested
- Power cord integrity checked
- Main switch toggled
- Indicator lights observed
- Battery presence/condition noted
- Table status after checks
Final Thought
Always prioritize patient safety and perform logical, stepwise troubleshooting. External verification can save time and prevent unnecessary repair costs. Proper CCR documentation preserves clear communication and supports department efficiency.
That is successful troubleshooting.
