What This Guide Helps With
Error 120.4630 indicating battery overvoltage condition, preventing safe charging or operation and signaling battery or internal power system fault.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Remove the pump from patient use immediately
- Transfer infusion to another functioning pump
- Confirm therapy continues safely
2. Verify the Reported Error and Behavior
- Power on the pump and confirm Error 120.4630 is displayed
- Observe when the error occurs (startup, docking, or charging)
- Check if the pump powers on and if charging indicators are present
3. Check Docking Station or AC Power Source
- Undock the pump and attempt to run on battery
- Try a different dock or channel if available
- Plug into a known good outlet
- Avoid power strips or extension cords
4. Inspect Docking Interface and Contacts
- Check rear docking contacts for dirt, corrosion, or bent pins
- Clean contacts if necessary
- Ensure the pump seats fully and securely in the dock
5. Power Cycle the Pump
- Remove from dock or AC power
- Power off if possible
- Wait 30–60 seconds
- Power back on and reconnect
6. Check for Battery Abnormalities
- Inspect for excessive heat
- Look for swelling or deformation
- Check for burning or unusual odor
7. Test Operation on Battery Only
- Undock the pump and attempt operation
- If it works, suspect charging/dock issue
- If it fails, suspect battery failure
8. Try Known Good Dock or Module (If Available)
- Place the pump in a known working dock/channel
- Observe if the error clears
If the Problem Persists
If Error 120.4630 remains after all external checks:
- Failed battery pack (overvoltage condition)
- Internal charging circuit failure
- Power management board fault
Remove the device from service, label it Out of Service, and send for repair or battery replacement.
Clinical Use Tip
Never troubleshoot on an active patient. Always transfer the patient to a backup device before continuing diagnostics.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 120.4630 battery voltage too high and not charging properly."
Cause
What was observed during troubleshooting.
Example:
"Error persisted after verifying dock, outlet, and cleaning contacts; suspected battery or internal charging fault."
Resolution
What action was taken.
Example:
"Removed from service, labeled out of service, and sent for battery replacement or internal repair."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
With Alaris systems, always consider the dock as part of the power system. Rule out external power issues first, but recognize when internal battery or charging faults require escalation.
That is successful troubleshooting.
