Key tips
- ·Free-flow protection must be verified on every PM - a failed anti-free-flow clamp is a direct overdose risk.
- ·Test occlusion alarms in both directions - failing to alarm when it should is more dangerous than a false alarm.
- ·Battery run-time complaints are the most common real-world nuisance call - a full charge/discharge cycle test catches most of them.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Occlusion / downstream blockage
HighSymptoms: Occlusion alarm, no flow, upstream pressure high.
Root cause: Kinked set, clamped line, patient vein issue.
Free-flow (failure of anti-free-flow)
HighSymptoms: Uncontrolled flow when door open.
Root cause: Worn roller or failed free-flow valve.
Motor / drive failure
MediumSymptoms: Stalled infusion, inaccurate rate.
Root cause: Peristaltic motor or encoder wear.
Door / carriage sensor fault
LowSymptoms: Set not recognized, door-open error.
Root cause: Dirty or failed door microswitch.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Occlusion pressure and flow-rate accuracy verification
- ·Battery conditioning cycle
- ·Door latch and air-in-line sensor inspection
- ·Post-drop functional check before return to service
- ·Annual PM per manufacturer schedule
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Occlusion / downstream blockage
- Confirm the presentation - typically occlusion alarm, no flow, upstream pressure high - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: kinked set, clamped line, patient vein issue.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the iV administration set per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Air-in-line detection
- Confirm the presentation - typically air-in-line alarm, infusion paused - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: air in set, improperly primed tubing.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the peristaltic roller / pump mechanism per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
