What This Guide Helps With
Error 240.4150 indicating high bottle-side pressure sensor voltage causing infusion interruption or inaccurate pressure monitoring.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the pump from active patient use
- Transfer infusion to a backup pump if needed
- Ensure therapy continues safely
Verify the Reported Error and Behavior
- Power on the pump and confirm Error 240.4150 is displayed
- Observe when the error occurs (startup or during infusion)
- Check if infusion stops immediately
- Look for prior occlusion alarms or abnormal pressure behavior
Check IV Set Installation and Compatibility
- Remove and inspect the IV set
- Ensure proper routing through the pump channel
- Verify correct seating in the pumping/pressure segment
- Confirm use of BD-approved Alaris infusion set
- Reinstall or replace with a known-good set
Inspect for Occlusions or Line Restrictions
- Trace the entire IV line
- Check for kinks or pinched tubing
- Ensure roller clamps are open
- Inspect for blockages at the patient site
- Correct any restriction and retest
Inspect Pump Channel and Pressure Interface
- Open the pump door and inspect the channel area
- Check for fluid contamination or residue
- Look for debris or buildup at the pressure sensor contact area
- Inspect for worn or damaged components
- Clean per approved procedures if needed
Check Module Seating (If Modular System)
- Reseat the infusion module
- Ensure secure connection to the PC unit
- Inspect for bent pins or connection issues
Power Cycle the Pump
- Turn the device off
- Wait 10–15 seconds
- Power the device back on
Test with a Known-Good Pump or Module
- Set up the same IV configuration on another pump/module
- Compare behavior
If the Problem Persists
If Error 240.4150 continues after external checks:
- External causes have been ruled out
- The issue strongly indicates internal pressure sensor or circuit failure
- Remove the device from service
- Label Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot on an active patient. Move the patient to a backup device before performing any troubleshooting steps.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"BD Alaris pump displaying Error 240.4150 (Bottle-side pressure sensor voltage too high), infusion stopped"
Cause
What was observed during troubleshooting.
Example:
"Internal pressure sensor fault suspected after ruling out IV set, occlusion, and channel contamination"
Resolution
What action was taken.
Example:
"Removed from service, labeled out of service, and sent for repair"
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Pressure sensor errors directly affect infusion safety. A structured approach—starting with tubing and setup—prevents unnecessary repairs while ensuring timely escalation when needed.
That is successful troubleshooting.
