What This Guide Helps With
Error 347 Check Battery indicating defective battery causing power instability, failure to hold charge, or unexpected shutdown during operation.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the pump from patient use immediately if the error is active
- Transfer infusion to a known working pump
- Confirm therapy continues without interruption
Verify the Reported Error and Behavior
- Power on the pump and confirm Error 347 Check Battery is displayed
- Observe when the error occurs (startup, during operation, or when unplugged)
- Check for rapid battery drain, inability to run on battery, or unexpected shutdowns
Check AC Power Source and Power Adapter
- Plug the pump into a known working outlet
- Ensure the power supply is securely connected
- Verify indicator lights and normal AC operation
Inspect Battery Installation
- Ensure the battery is properly seated (if accessible without disassembly)
- Check for loose fit, corrosion, swelling, or physical damage
- Confirm secure connections
Check Charging Behavior
- Leave the pump connected to AC power for a full charging period
- Observe charge indicators and behavior
- Check if the error persists after charging
Attempt Operation on Battery Only
- Disconnect AC power after charging
- Operate the pump using battery power only
- Monitor for immediate shutdown or instability
Swap with Known Good Battery
- Install a known working battery if available
- Observe whether the error clears
- Confirm normal operation if replaced
If the Problem Persists
If Error 347 remains after battery replacement and external checks:
- External causes have been ruled out
- This indicates a possible internal charging or power management failure
- Remove device from service
- Label Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot on an active patient. Always move the patient to a backup device before evaluating battery or power-related issues.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 347 Check Battery. Unit shuts down when unplugged."
Cause
What was observed during troubleshooting.
Example:
"Battery failed to hold charge and error persisted until replaced. Verified with known good battery."
Resolution
What action was taken.
Example:
"Replaced defective battery and verified proper charging and operation. Returned unit to service."
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 patient safety due to the risk of therapy interruption. Always verify reliable power operation and escalate promptly when internal faults are suspected.
That is successful troubleshooting.
