What This Guide Helps With
Identifies external causes of generator faults or exposure errors, such as power supply issues, system interlocks, or exposure settings, preventing procedure interruptions.
Step-by-Step Troubleshooting
Ensure Patient and Staff Safety
Confirm no patient is on the table and staff are clear.
Why: Prevents accidental radiation exposure during troubleshooting.
Check System Power and Electrical Connections
Verify the main power switch is ON, circuit breakers are engaged, and power cables are securely connected.
Expected outcome: Stable power to the generator; fault indicators should reset.
Inspect Exposure Interlocks and Safety Switches
Check table, collimator, and cabinet interlocks; ensure all doors/panels are closed properly.
Why: Open interlocks prevent generator firing to protect patients.
Review Exposure Settings and Protocols
Confirm the correct imaging protocol is selected, with appropriate kVp/mA ranges.
Expected outcome: Generator accepts exposure commands without fault.
Check System Error Messages or Logs
Access the system’s service or error log to identify the specific fault code.
Why: Helps distinguish user input errors from hardware issues.
Perform a Soft Reset or Power Cycle
Power down the system, wait 60 seconds, and restart.
Expected outcome: Temporary software or communication errors may clear.
Swap or Inspect Accessories if Applicable
For systems with removable cables or detectors, ensure connectors are fully seated and undamaged.
Why: Loose or damaged connections can cause generator errors.
If the Problem Persists
All external and operational checks have been performed.
Remove the system from clinical service.
Label “Out of Service” and contact Philips service for bench evaluation or component repair.
Proper escalation prevents patient risk and equipment damage.
Clinical Use Tip
Never attempt exposures during troubleshooting; move patients to another functioning system.
Only trained Clinical Engineering staff should operate or reset interlocks and generator controls.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Generator fault displayed during routine procedure, exposure not possible."
Cause
What was observed during troubleshooting.
Example:
"Exposure interlock engaged due to partially open table panel; power cycle cleared temporary software fault."
Resolution
What action was taken.
Example:
"Verified interlocks and connections, performed system reset, exposure restored successfully; no further faults observed."
Helpful Details to Include
- Outlet and UPS tested
- Power cables verified
- Interlocks checked
- Error codes noted
- Soft reset performed
- Device returned to service status
Final Thought
Patient safety is paramount. Troubleshooting must follow logical, external-first steps. Escalation to manufacturer service is appropriate when internal generator faults persist. Documentation ensures continuity and safety.
That is successful troubleshooting.
