What This Guide Helps With
This guide assists Clinical Engineering in troubleshooting situations where the Skytron Aurora surgical light head does not power on. Common causes include older or degraded wiring, transformer issues, or power supply faults. The focus is on external, verifiable checks before assuming internal failure, while ensuring patient safety.
Step-by-Step Troubleshooting
Verify Power Availability
- Confirm the room or circuit supplying the light is energized.
- Check for tripped breakers or blown fuses.
Why: Ensures the issue isn’t simply a loss of facility power.
Inspect Wall Switch or Control Panel
- Operate the on/off switch or control interface.
- Observe any response from the light head (LED indicators, humming).
Why: Confirms the signal to the light head is reaching it.
Check Visible Wiring Connections
- Examine accessible wiring between the ceiling mount, transformer, and light head for loose connections or obvious damage.
- Ensure connectors are seated fully and not corroded.
Why: Older wiring can develop loose or oxidized connections that prevent operation.
Inspect Transformer or Power Supply Module
- If accessible, verify the transformer is securely connected and shows normal indicators (if any).
- Look for signs of overheating, burn marks, or unusual smells.
Why: The transformer provides the correct voltage; faults here commonly prevent power-on.
Swap with Known-Good Circuit or Transformer (if possible)
- Temporarily connect the light head to a verified functional power source.
Why: Helps isolate whether the issue is in the light head or upstream wiring/transformer.
Test Light Head Independently (Optional External Test)
- If the design allows, remove the head and connect to an alternative verified supply per manufacturer safety guidelines.
Why: Confirms whether the light head itself is functional.
If the Problem Persists
If external checks and transformer/wiring inspections fail to restore power, the issue is likely internal or requires professional repair.
- Remove the light from service.
- Label as Out of Service.
- Send for repair or bench evaluation.
Note: Avoid internal disassembly beyond what is accessible externally, as this may void warranty or create safety hazards.
Clinical Use Tip
Do not attempt troubleshooting while a patient is under the light.
Move procedures to an alternate, functional light.
Always ensure power is off before inspecting wiring to prevent electrical shock.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
Light head fails to power on; no illumination during operation.
Cause
What was observed during troubleshooting.
Example:
External inspection shows loose transformer wiring and possible degraded connector; no visible signs of light head failure.
Resolution
What action was taken.
Example:
Secured wiring connections; light tested with alternate power supply; issue persists. Light removed from service and sent for repair.
Helpful Details to Include
- Outlet/circuit tested and functional
- Control panel switches verified
- Transformer indicator lights observed
- Wiring connections inspected
- Light head response (none or intermittent)
- Any unusual smells or heat from transformer
Final Thought
Proper troubleshooting balances logic, patient safety, and timely escalation. Document all steps clearly; knowing when to stop and escalate is as critical as finding the fault. Well-documented inspections support repairs and prevent unnecessary downtime.
That is successful troubleshooting.
