What This Guide Helps With
Use this guide when a required patient-connected cable, lead, sensor, or related connection is not detected by the generator.
Step-by-Step Troubleshooting
1. Protect the Patient and Stop Dependence on the Affected Connection
Do not continue therapy when a required patient cable, lead, or sensor is missing, unreliable, or not recognized. Notify the clinical team and maintain patient care using an approved alternate setup if needed.
Expected outcome: The patient is not dependent on an unreliable connection. Troubleshooting can proceed safely.
2. Confirm Which Connection Is Not Detected
Identify the exact cable, lead, sensor, or interface reported as missing. Record any displayed message and determine whether detection never occurs or drops in and out.
Expected outcome: The affected connection and failure behavior are clearly identified.
3. Inspect the External Connection
Verify the connector is fully inserted into the correct receptacle and properly secured where applicable. Look for bent contacts, damaged housings, contamination, fluid, strain, or looseness.
Expected outcome: The connection is physically intact and correctly seated. If reseating restores stable detection, proceed to final verification.
4. Inspect the Entire Cable or Lead
Trace the cable from end to end. Look for cuts, crushed areas, severe bends, stretched sections, damaged strain reliefs, or evidence of repeated flexing.
Expected outcome: No external cable damage is present. A visibly damaged cable should be removed from service rather than manipulated during patient use.
5. Verify Compatibility
Confirm the cable, lead, sensor, catheter interface, or accessory is intended for the DiamondTemp system and the planned clinical configuration. Do not force connectors or substitute unapproved accessories.
Expected outcome: The connected accessory is appropriate for the system. Incorrect accessories are replaced with approved compatible components.
6. Use a Known-Good Approved Accessory
When available, substitute a known-good compatible cable, lead, or sensor while the equipment is not supporting active therapy.
Expected outcome: If the known-good accessory is recognized normally, the original accessory is the likely external cause and should be removed from service.
7. Compare Ports or Interfaces Only Where Approved
If the system provides equivalent approved connection paths, compare behavior using manufacturer-supported connections without changing protected configuration.
Expected outcome: The problem is isolated to an external accessory, connection point, or broader generator recognition issue.
8. Restart the System if Clinically Appropriate
With the patient disconnected from therapy and accessories properly installed, perform a normal restart if recognition remains absent.
Expected outcome: The system detects the required connection after startup. If recognition is stable, proceed to verification.
9. Perform Final Functional Verification
Confirm the accessory remains recognized during normal external handling and that related displays, measurements, and readiness indicators behave appropriately. Complete manufacturer-required checks before return to service.
Expected outcome: Detection remains stable and the system passes functional verification. The issue is resolved and troubleshooting can stop.
10. Escalate Persistent Detection Failure
If known-good compatible accessories are not detected despite correct connections, remove the generator from clinical use.
Expected outcome: The device is referred for qualified evaluation rather than deeper unauthorized troubleshooting.
If the Problem Persists
External connection, accessory, and compatibility causes have been ruled out. Remaining possibilities include a damaged receptacle, interface circuitry, configuration issue, communication fault, or other service-level problem.
Remove the device from service, label it Out of Service, and send it for bench evaluation or manufacturer-supported repair. Use approved documentation and test equipment. Repairs or configuration changes should be performed only by qualified personnel.
Complete required operational and safety testing before returning the generator to clinical use. Stopping after safe external isolation is proper troubleshooting.
Clinical Use Tip
Never continue ablation therapy when a required patient-connected component is intermittently or incompletely recognized.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported that the DiamondTemp generator intermittently failed to detect a connected patient cable."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found damage at the cable strain relief that caused detection to drop when the cable was moved."
Resolution
What action was taken.
Example:
"Clinical Engineering replaced the damaged cable with an approved known-good cable and verified stable detection and normal system readiness."
Helpful Details to Include (If Known)
- Exact connection not detected
- Displayed message
- Connector and receptacle condition
- Cable strain-relief condition
- Approved accessory identification
- Known-good substitution result
- Whether failure was constant or intermittent
- Results after reseating or replacement
- Final device status
Final Thought
Maintain patient safety, identify the exact missing connection, inspect and substitute external components before blaming the generator, verify stable recognition after correction, escalate appropriately, and document the event clearly.
That is successful troubleshooting.
