What This Guide Helps With
This guide addresses Error: 9 RS232 Communication Transmit Error, which indicates a failure in the pump’s internal communication system. This can result in loss of functionality, unreliable operation, or inability for the device to properly run or interface with internal components.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Immediately remove the pump from patient use if actively infusing
- Transition feeding to a backup pump or approved alternative
- Confirm feeding continues without interruption
2. Verify the Reported Error and Behavior
- Power on the pump and confirm Error: 9 is displayed
- Observe whether the error appears at startup or during operation
- Check for frozen interface, alarms, or loss of function
3. Perform a Power Cycle
- Turn the pump off
- Disconnect from AC power
- Wait 30–60 seconds
- Reconnect power and restart the pump
- Observe if the error clears
4. Check for External Accessories or Connections
- Remove any connected accessories if applicable
- Inspect power adapter and cable for damage
- Ensure proper docking or mounting if used with a station
5. Inspect Physical Condition of the Pump
- Check for signs of drops, impact, or liquid exposure
- Inspect for loose casing or damaged ports
- Verify overall structural integrity
6. Reattempt Operation
- Attempt to run a basic feeding or setup cycle
- Monitor for immediate recurrence of Error 9
- Confirm whether normal operation is restored
If the Problem Persists
If Error 9 continues after completing all external troubleshooting steps, external causes have been ruled out. This condition indicates an internal RS232 communication failure within the device.
Remove the pump from service, label it as Out of Service, and send it for repair or bench evaluation.
Clinical Use Tip
Never troubleshoot or rely on a feeding pump displaying internal communication errors while connected to a patient. Always transition the patient to a confirmed working device first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 9 RS232 communication transmit error and not functioning properly during feeding."
Cause
What was observed during troubleshooting.
Example:
"Internal communication fault confirmed after power cycle and external checks did not resolve the error."
Resolution
What action was taken.
Example:
"Removed pump from service, labeled out of service, and sent for repair evaluation."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Error 9 indicates a failure in the pump’s internal communication pathway. Once basic troubleshooting steps are completed and external causes are ruled out, proper escalation is critical. Do not attempt extended use of a device with internal communication faults.
That is successful troubleshooting.
