What This Guide Helps With
This guide assists Clinical Engineering in troubleshooting situations where the Aurora surgical light experiences communication errors with its wall or remote control panels. Such errors may manifest as unresponsive panels, error codes, or intermittent functionality. The guide focuses on external and easily verifiable checks before assuming internal board or module failure.
Step-by-Step Troubleshooting
Verify Power to Light Head and Control Panels
- Check that the surgical light is powered on.
- Verify that the wall or remote control panel is receiving power (indicator LEDs on the panel).
- Why it matters: Communication errors can appear if either device is unpowered.
Inspect Connection Cables
- Check the communication cable between the light head and wall/remote panel for loose connections, fraying, or visible damage.
- Reseat connectors on both ends if applicable.
- Why it matters: Loose or damaged cables are a common cause of intermittent communication errors.
Check Network or Bus Wiring (If Applicable)
- For lights using data buses (RS-485, CAN, or proprietary), ensure continuity with a cable tester or visual inspection.
- Confirm no junction boxes or splitters are damaged or disconnected.
- Why it matters: Broken or improperly terminated data lines can prevent panel commands from reaching the light head.
Test Alternate Control Panel (If Available)
- Swap the wall or remote panel with another known-working unit.
- Why it matters: Isolates whether the error is with the light head or the panel.
Power Cycle the System
- Turn off the light and panels for 30 seconds, then power back on.
- Why it matters: Resets temporary communication faults in electronics.
Observe Error Indicators
- Check the light head for any diagnostic LEDs or error codes.
- Note if the error is intermittent or constant.
- Why it matters: Provides clues about whether the problem is systemic or isolated to one panel.
If the Problem Persists
External checks and basic power/network verifications have been completed.
The issue may involve the light head controller board or internal panel electronics.
- Remove the device from service.
- Label as Out of Service.
- Send for repair or bench evaluation by qualified service personnel.
Note: Knowing when to stop is a critical part of proper troubleshooting and protects both patient safety and device integrity.
Clinical Use Tip
Do not attempt to troubleshoot communication errors during an active case.
Move the patient to another operational light if necessary.
Troubleshooting should only be performed when the surgical area is clear and safe.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
Wall control panel intermittently unresponsive; error code displayed on Aurora surgical light.
Cause
What was observed during troubleshooting.
Example:
Communication cable between light head and panel was loose; power cycling did not resolve issue completely.
Resolution
What action was taken.
Example:
Cable resecured, system tested; if issue recurs, panel or light head controller board requires service.
Helpful Details to Include
- Outlet tested and verified
- Power indicators on panels and light head
- Cable condition and connection points checked
- Error codes or LED indicators noted
- System behavior after power cycling
Final Thought
Effective troubleshooting balances patient safety, logical inspection, and escalation when external checks are exhausted. Proper documentation ensures clear communication for follow-up service and supports continuity of care.
That is successful troubleshooting.
