What This Guide Helps With
Addresses lost communication between imaging components caused by power, loose cables, disturbed connections, startup sequence, network links, or workstation availability.
Step-by-Step Troubleshooting
1. Protect the Patient and Maintain Imaging Availability
If the C-arm and workstation or monitor cart cannot communicate reliably during a procedure, do not continue depending on the system for imaging, review, or guidance.
Provide another verified imaging system if the communication failure compromises patient care.
Expected outcome: Clinical care continues without dependence on an incomplete imaging chain.
2. Confirm the Communication Failure
Determine whether:
- The workstation is completely offline.
- Monitors are blank.
- The C-arm operates but images do not appear.
- Controls respond locally but not remotely.
- Communication fails after system movement.
- The issue occurs only at startup.
- A specific connection or communication warning appears.
Expected outcome: The affected communication path is clearly identified.
3. Verify Power to All Required Components
Confirm that the C-arm, workstation, monitor cart, displays, and any required external components are powered.
Inspect visible power indicators and verify accessible power cords are secure.
If one component is unpowered, verify its facility receptacle or approved power source.
Expected outcome: All required components receive stable power. If restoring power resolves communication, continue to verification.
4. Inspect External Communication Cables
Inspect all accessible cables connecting system components.
Look for:
- Partially seated connectors.
- Loose locking mechanisms.
- Damaged connector shells.
- Bent accessible contacts.
- Pinched or crushed cables.
- Cables pulled during transport.
- Improper cable routing.
Reseat approved external connections under the appropriate powered-down condition.
Expected outcome: Required communication links are securely connected.
5. Check Monitor Signal and Display Controls
If communication appears normal but a display is blank, verify:
- The monitor is powered.
- Brightness is not turned fully down.
- The correct input or system source is selected when user-accessible.
- Video cables are connected.
- A second system display shows the same problem.
Avoid treating a display-only failure as a complete system communication failure.
Expected outcome: A monitor-specific problem is identified or ruled out.
6. Check Cable Behavior During Movement
Observe accessible communication cables while the C-arm or cart is safely repositioned.
Look for a connection that becomes loose, stretched, or intermittent when equipment moves.
Expected outcome: Communication remains stable during normal movement.
7. Verify Startup Sequence and Component Readiness
If the issue appears after startup, perform a normal controlled shutdown and restart of the system according to approved operation.
Allow all components to initialize completely before assessing communication.
Expected outcome: The workstation and imaging system recognize one another normally after startup.
8. Check Operator-Accessible Network or System Status
Review available system indicators for connection state without entering restricted service menus.
If the workstation uses an accessible network connection as part of system operation, inspect the physical connection and available link indication.
Do not alter IP addresses, system names, or protected communication settings without documented authorization.
Expected outcome: The external connection path is intact and no unauthorized configuration change is introduced.
9. Perform End-to-End Functional Verification
Verify:
- C-arm controls operate.
- Images are acquired.
- Images appear at the intended workstation or monitors.
- Commands are responsive.
- Communication remains stable through repeated acquisition and normal positioning.
- No communication warnings recur.
Expected outcome: The full system communication path operates normally. Troubleshooting can stop.
10. Escalate Persistent Communication Failure
Remove the Cios Spin from service if required components remain disconnected, images cannot reliably reach the workstation, or communication drops intermittently without an external cause.
Do not open computers, communication modules, or control electronics for board-level troubleshooting.
Expected outcome: A system with unreliable internal communications is routed for qualified service.
If the Problem Persists
After component power, external cabling, monitor inputs, cable routing, startup state, and accessible network indications have been ruled out, remaining causes may involve internal communication hardware, workstation software, embedded computers, network interfaces, system configuration, or internal cabling.
The Cios Spin should be:
- Removed from service.
- Labeled Out of Service.
- Sent for repair or bench/service evaluation.
- Evaluated using Siemens Healthineers documentation and approved test equipment.
- Repaired or configured only by qualified personnel.
Complete image acquisition, display, communication, and other applicable return-to-service testing before clinical use.
Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
Verify the entire imaging chain from acquisition through display; a functioning C-arm is not clinically usable if required images cannot reach the viewing workstation.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Staff reported the Cios Spin acquired images but the images did not appear on the workstation monitors."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found an external communication cable between system components was loose following equipment relocation."
Resolution
What action was taken.
Example:
"The cable was reseated and secured, repeated images transferred and displayed normally, and communication remained stable during positioning checks."
Helpful Details to Include (If Known)
- Component that appeared offline.
- Monitor power status.
- Exact communication warning.
- Power cords checked.
- Communication cables inspected.
- Recent equipment movement.
- Cable-position dependency.
- Restart results.
- Network/link indicators.
- Image-transfer verification.
- Final device status.
Final Thought
Check power, cabling, displays, and startup state before assuming an internal communication failure, verify the complete imaging path after correction, and escalate any intermittent connection that cannot be externally explained.
That is successful troubleshooting.
