What This Guide Helps With
Identifies external causes of generator faults or exposure errors, such as power instability, interlocks, or incorrect settings, ensuring safe and uninterrupted procedures.
Step-by-Step Troubleshooting
Ensure Patient and Staff Safety
- Confirm no patient is on the table and staff are clear.
Why: Prevents injury from unexpected exposure or table movement.
Verify Main Power Supply
- Check that the system is plugged into a dedicated outlet with correct voltage.
- Inspect circuit breakers and UPS (if present).
Expected Outcome: System powers on without error.
Check System Interlocks
- Inspect all doors, panels, and footswitches for proper closure and function.
Expected Outcome: Interlocks engaged, no error indicators lit.
Inspect Cables and Connections
- Verify high-voltage, generator, and control cables are secure and undamaged.
Expected Outcome: No loose or damaged connections causing fault.
Review Exposure Settings
- Confirm appropriate kV, mA, and dose settings for the procedure.
Expected Outcome: Settings within acceptable range; no exposure error.
Restart the System
- Perform a controlled shutdown and restart.
Expected Outcome: Error resolves; system ready for use.
If the Problem Persists
External causes are likely ruled out.
Action:
- Remove the system from service.
- Label Out of Service.
- Schedule vendor repair or in-house bench evaluation.
Note: Stopping before internal troubleshooting prevents accidental damage or patient risk.
Clinical Use Tip
Never attempt exposures while troubleshooting.
Move the patient to a backup fluoroscopy system before any checks.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Generator fault displayed during procedure initiation."
Cause
What was observed during troubleshooting.
Example:
"Power interruption detected at main supply; exposure settings outside recommended range."
Resolution
What action was taken.
Example:
"Corrected outlet issue and reset exposure parameters; system tested successfully."
Helpful Details to Include (If Known)
- Outlet tested and verified
- UPS or power conditioner checked
- Interlock status
- Indicator lights and alarm behavior observed
- Cables inspected for damage
Final Thought
Systematic troubleshooting ensures patient safety, prevents unnecessary downtime, and allows clear documentation. Knowing when to escalate is as important as resolving simple issues.
That is successful troubleshooting.
