What This Guide Helps With
Troubleshoots unavailable positioning or associated table-motion functions by checking safety interlocks, controls, connections, obstructions, and integrated equipment before escalation.
Step-by-Step Troubleshooting
1. Protect the Patient From Unintended Movement
Do not troubleshoot unavailable or unpredictable positioning while patient safety depends on the affected motion system.
Prevent unintended patient movement, secure lines and catheters, and have clinical staff maintain safe patient positioning. Use alternate positioning methods only when approved for the procedure.
Expected outcome: The patient is secure and no troubleshooting action can produce unsafe motion.
2. Confirm Which Motion Function Is Affected
Determine exactly what clinical staff mean by unavailable motion.
Identify whether the problem involves:
- An associated procedure table
- An integrated positioning device
- A peripheral navigation component
- One direction of movement
- All movement
- A control input that is not responding
Do not assume the OPAL HDx itself contains a gantry or powered patient table.
Expected outcome: The affected external or integrated positioning component is identified. If the reported function belongs to another asset, route troubleshooting to that equipment.
3. Verify Power to the Affected Positioning Equipment
Confirm that the table or positioning component has facility power and shows normal power indications.
Check accessible power cords, plugs, approved power distribution, and emergency-stop conditions where applicable.
Do not bypass interlocks or emergency-stop circuits.
Expected outcome: The affected component has normal power available. If power restoration returns normal motion, troubleshooting can stop after controlled verification.
4. Check for Mechanical Obstruction
Inspect the immediate area for:
- Equipment blocking movement
- Cables caught under wheels or moving sections
- Patient lines limiting travel
- Accessories interfering with movement
- Locked casters or transport features
- Physical contact with another system
Do not force movement against resistance.
Expected outcome: The intended motion path is clear and no external obstruction is present. If removal of an obstruction restores normal operation, troubleshooting can stop after testing.
5. Inspect External Control Connections
Check accessible connections for foot controls, hand controls, interface cables, or other external positioning controls associated with the affected equipment.
Look for disconnected, loose, damaged, or contaminated connectors.
Expected outcome: External positioning controls and connections are intact and securely connected.
6. Verify Control State and Interlocks
Confirm that normal clinical control conditions are satisfied according to approved operating procedures.
Check for obvious:
- Emergency-stop activation
- Transport or lock mode
- Incomplete system startup
- Accessory not fully seated
- Another control station holding priority
Do not bypass safety interlocks.
Expected outcome: No external control-state condition is preventing authorized motion.
7. Isolate the Mapping System From the Positioning Failure
Determine whether OPAL HDx remains operational while only the associated positioning device is unavailable.
If the table or motion device is a separate asset, test it independently using its approved troubleshooting process.
Expected outcome: The fault is isolated to either the mapping system interface or the separate positioning equipment.
8. Perform Controlled Motion Verification
With no risk to a patient, test available positioning functions using normal controls.
Observe for:
- Smooth response
- Correct direction
- No unexpected stops
- No unusual noise
- No intermittent control response
Expected outcome: Required positioning functions operate consistently. Troubleshooting can stop if normal controlled operation is restored.
9. Escalate Unresolved or Unsafe Motion Problems
If motion remains unavailable, intermittent, or unpredictable, remove the affected positioning equipment from service.
Do not perform internal motor, drive, control-board, or interlock repair without approved service procedures.
Expected outcome: Unsafe or unresolved positioning equipment is prevented from clinical use and referred for qualified repair.
If the Problem Persists
Common external power, obstruction, control, connection, and operating-state causes have been ruled out. The remaining problem may involve the separate table, positioning hardware, interface circuitry, internal controls, or system integration.
The affected equipment should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
- Evaluated using appropriate manufacturer documentation and approved test equipment
- Repaired or configured only by qualified personnel
Verify safe motion, controls, interlocks, and any required mapping-system interaction before return to service.
Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
Secure the patient, catheters, cables, and procedural equipment before testing any table or positioning motion.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Clinical staff reported that the procedure table would not move while preparing the OPAL HDx setup."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found an external equipment cable obstructing the table's travel path and preventing normal positioning."
Resolution
What action was taken.
Example:
"Clinical Engineering cleared and secured the cable, verified smooth table movement in the required directions, and confirmed the mapping-system setup remained operational."
Helpful Details to Include (If Known)
- Exact motion function affected
- Separate table or positioning asset involved
- Power status
- Emergency-stop or lock condition
- Control used
- Cable or obstruction condition
- Directions tested
- Mapping-system status
- Result after correction
- Final equipment status
Final Thought
Protect the patient from unintended movement, identify which asset actually provides the affected motion, check simple external causes first, and escalate any unresolved or unpredictable movement condition. Clear CCR documentation should reflect both the positioning problem and final verification.
That is successful troubleshooting.
