What This Guide Helps With
Error 120.4510 indicating battery missing or disconnected, causing loss of backup power and risk of pump shutdown when unplugged.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- If the pump is in use, immediately connect to AC power or transfer infusion to another pump
- Ensure therapy continues without interruption
2. Verify the Reported Error and Behavior
- Confirm Error 120.4510 is displayed
- Check if error appears at startup or during infusion
- Observe if pump alarms or shuts down when unplugged
- Verify operation while on AC power
3. Confirm AC Power Function
- Plug into a known working outlet
- Verify AC indicator light is on
- Confirm pump powers normally on AC
4. Check Battery Presence and Seating
- Remove battery from rear compartment
- Inspect proper orientation and full insertion
- Ensure latch or door is fully secured
- Reinstall firmly and power cycle
5. Inspect Battery Contacts and Compartment
- Check for clean, intact contacts
- Look for corrosion or debris
- Ensure pins are not bent or recessed
6. Test with a Known Good Battery
- Install a verified working battery
- Power on the pump
- Disconnect AC power briefly
7. Check for Battery Recognition Behavior
- Observe battery icon and level on display
- Confirm charging indicator is active when plugged in
8. Evaluate for Internal Failure
- If battery is not recognized after replacement
- If error persists
- If pump shuts off when unplugged
- Suspect internal battery interface or charging circuit failure
If the Problem Persists
After confirming battery and external conditions:
- Remove the device from service
- Label as Out of Service
- Send for repair or PC unit evaluation
Persistent battery detection errors strongly indicate internal failure.
Clinical Use Tip
Never troubleshoot on an active patient. Move the patient to a backup device first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Alaris pump displaying Error 120.4510 and powers off when unplugged."
Cause
What was observed during troubleshooting.
Example:
"Battery not recognized after reseating and replacement with known good battery, indicating internal power or battery interface failure."
Resolution
What action was taken.
Example:
"Verified AC power, reseated battery, installed known good battery. Error persisted. Removed from 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
Battery-related errors directly impact infusion continuity and patient safety. Always verify simple external causes first, but escalate quickly when backup power is unreliable.
That is successful troubleshooting.
