CareFusion Alaris PCU BD 8000
CareFusion · Model Alaris PCU BD 8000
Provides a common user interface for programming infusion and monitoring modules This helps to reduce complexity at the point of care. The Medley Medication Safety System is a modular infusion and monitoring system designed to provide SpO2 monitoring capabilities and accurate, automated infusion of a broad range of intravascular fluids, medications, and blood products.
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
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Failure / error message stops delivery
HighSymptoms: The pump alarms and displays an error message / code and stops.
Root cause: A subsystem fault indexed in the service manual - motor / drive, a sensor, set-detection, or a board.
Occlusion alarm / pressure fault
MediumSymptoms: Repeated occlusion alarms, delivery stops, or an occlusion is missed.
Root cause: Kinked or clamped line, a closed roller clamp, a positional patient tube, pressure-sensor drift, or an improperly loaded set.
Air-in-line alarm
MediumSymptoms: Frequent air-in-line alarms, delivery stops.
Root cause: Air in the set, an improperly loaded set, or an ultrasonic air-detector fault.
Flow-rate accuracy drift
MediumSymptoms: Delivered volume outside tolerance on the annual test, especially at low rates.
Root cause: Worn pumping mechanism / plunger drive.
Battery will not hold charge
MediumSymptoms: Short run time, low-battery early after a full charge.
Root cause: Aged battery pack.
Door / plunger / sensor mechanical wear
LowSymptoms: Set will not load, door will not latch, plunger grip poor.
Root cause: Worn door latch, plunger jaws, or anti-free-flow mechanism.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Alarm with an error message / code, delivery stopped
- Note the exact error message or code from the display.
- Look it up in the pump's technical service manual troubleshooting section.
- Run the biomed diagnostics / service utilities to exercise the named subsystem (motor / drive, a sensor, set-detection, a board).
- Follow the manual's parts-replacement procedure for that fault.
- Run the full scheduled-maintenance test set, including a flow-accuracy check, after any repair.
Symptom: Occlusion alarm / pressure fault (or a missed occlusion)
- Check the line for kinks, closed clamps and a closed roller clamp; check the patient site and cannula.
- Reload the administration set correctly, clearing all air.
- Confirm the set is an approved type for this pump.
- Run the pressure-sensor / force-sensor test in the service menu.
- Replace the set; refer the pump if the pressure sensor or pumping mechanism is indicated.
Symptom: Air-in-line alarm / free-flow or feed not delivering
- Prime the set fully and reload it; tap out micro-bubbles at the drip chamber.
- Confirm the set seats correctly against the air-in-line detector / rotor.
- Clean the ultrasonic air-detector window.
- Run the air-detector (or rotor / cassette) test in diagnostics.
- Replace a worn pumping mechanism / anti-free-flow assembly if flow accuracy or detection is out.
Symptom: Battery will not hold charge / short run time
- Fully charge, then run a battery run-down / capacity test in the service menu.
- Check the charging circuit and contacts.
- Replace the battery pack when capacity is below the service limit.
- Recalibrate the battery gauge if the pump supports it.
- Confirm run time meets spec after replacement.

Documents & Manuals
Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Alaris PCA Module 8120, Patient Controlled Analgesia infusion pump: compatible syringes labeling contains syringes that have not been validated.
- RECALL
Cleaning agents may damage Inter-Unit Interface (IUI) Connectors, which may lead to interruption of communication or power between PC Unit and modules, which may result in an infusion that stops with a CHANNEL DISCONNECTED message, and an audio/visual alarm on the PC Unit and an interruption of therapy or monitoring.
- RECALL
If one or more screws or washers are loose or missing causing the battery not to be properly secured to the PC Unit, that is running on battery power, the system may experience a power loss with a prolonged, non-silenceable alarm. Power loss may result in an interruption of patient therapy or monitoring.
- RECALL
1)Error 255-XX-XXX results in inability to edit settings 2)Delay options programming may result in no KVO rate/therapy interruption 3)Software errors results in no low battery alarm/infusion stopping 4)Medium priority KVO/End of Infusion alarms may result in unrecognized infusion completion 5)Custom concentration data entry errors results in concentrations being lower/higher than medication orders
- RECALL
Reports where the Low Battery alarm and/or the Very Low Battery alarm are not being triggered before the battery is discharged and all infusion channels are stopped.
- RECALL
CareFusion is recalling the Alaris PC unit because a component on the PC unit power supply may cause a "System Error" or "Missing Battery" error code (120.4630).
