What This Guide Helps With
Troubleshoots a Volista surgical light that remains off, starts incompletely, or fails normal initialization due to power, connection, control, or external supply issues.
Step-by-Step Troubleshooting
1. Protect the Patient and Maintain Surgical Lighting
Do not troubleshoot unreliable surgical lighting while a patient or procedure depends on it. Activate verified alternate surgical lighting or move the procedure to another suitable light before beginning technical work. If the light behaves unpredictably, remove it from clinical use.
Expected outcome: Adequate alternate illumination is available and the affected Volista can be evaluated without affecting patient care.
2. Confirm the Exact Startup Failure
Ask clinical staff what occurred when the light was commanded on. Determine whether the entire system remained off, one light head failed, indicators appeared without illumination, or startup began and then stopped. Attempt normal operation only when the system is safely available for testing.
Expected outcome: The failure is reproduced or clearly defined. If normal startup now completes repeatedly, perform final functional verification and stop troubleshooting if satisfactory.
3. Verify Facility Power
Confirm that the surgical light system has its normal facility power available. Inspect accessible breakers, disconnects, power indicators, and external supply connections associated with the installation without opening energized equipment. Compare with another functioning system or have Facilities verify the branch supply when appropriate.
Expected outcome: Normal supply power is confirmed. If restoring an external power source returns reliable operation, verify the light and stop troubleshooting.
4. Inspect Accessible Power and System Connections
Inspect accessible external cables, connectors, wall controls, control panels, and interfaces for looseness, physical damage, contamination, or evidence of fluid intrusion. Reseat only connections intended for normal field access and only after placing the equipment in a safe condition.
Expected outcome: All accessible connections are secure and undamaged. If correcting a loose external connection restores startup, verify operation and stop troubleshooting.
5. Check the User Controls
Operate the normal power and light controls. Verify that buttons or touch controls are not physically stuck, damaged, contaminated, or obstructed. If multiple control locations are available, compare their behavior without entering restricted service functions.
Expected outcome: Normal controls respond consistently. If one external control location was preventing operation and the issue is corrected through an approved external action, complete functional testing and stop.
6. Determine Whether the Failure Is System-Wide or Isolated
If the installation contains multiple light heads or control locations, determine whether all components are affected or only one section. A system-wide failure can point toward shared power or control infrastructure, while an isolated failure helps narrow the service scope.
Expected outcome: The affected portion of the system is identified without assuming an internal component failure.
7. Check for Environmental or Physical Conditions
Inspect for recent construction, electrical work, liquid exposure, impact damage, unusual heat, unusual odor, or other environmental conditions that could explain the failure. Do not energize equipment showing evidence of electrical damage, overheating, or fluid intrusion.
Expected outcome: No unsafe environmental or physical condition is present. Any unsafe finding requires immediate removal from service.
8. Perform Final Functional Verification
After any external correction, cycle the system through normal operation several times. Verify startup, light output, controls, positioning, and any normally used light heads or accessories.
Expected outcome: The Volista starts consistently and performs normally. If so, troubleshooting is complete.
9. Escalate an Unresolved Startup Failure
If correct facility power and accessible connections are verified but the light still does not start normally, stop external troubleshooting. Do not open power assemblies or pursue board-level diagnosis unless specifically authorized and trained.
Expected outcome: The unresolved system is removed from clinical service and routed for qualified evaluation.
If the Problem Persists
Common external power, connection, control, and environmental causes have been ruled out. The remaining problem may involve internal power conversion, control electronics, installed wiring, system configuration, or another service-level condition.
The device should be removed from service, labeled Out of Service, and sent for repair or bench/on-site technical evaluation as appropriate. Evaluation should use current Getinge service documentation and approved test equipment. Internal repair or configuration should be performed only by qualified personnel.
Before return to service, verify reliable startup, light output, control response, positioning, and all clinically used functions. Knowing when to stop external troubleshooting and escalate is proper troubleshooting.
Clinical Use Tip
Confirm that verified alternate surgical illumination is available before disabling or troubleshooting any operating-room light needed for an active procedure.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"OR staff reported that the Getinge Volista surgical light would not power on from the normal control."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found facility power present but an accessible external system connection was not fully seated."
Resolution
What action was taken.
Example:
"Clinical Engineering secured the connection, verified repeated normal startups and light operation, and returned the system to service."
Helpful Details to Include (If Known)
- Whether the entire system or one light head was affected
- Facility power status
- Breaker or disconnect condition
- Indicator behavior during startup
- Accessible connection condition
- Control locations tested
- Evidence of damage, heat, odor, or fluid exposure
- Results before and after correction
- Final functional status
Final Thought
Protect the patient first, verify external power and connections before assuming an internal failure, test the complete lighting function after correction, and escalate unresolved faults with clear CCR documentation.
That is successful troubleshooting.
