What This Guide Helps With
Error 115 Sensor disparity (fast) indicates a motor overspeed condition where the pump is detecting faster-than-expected movement. This can lead to inaccurate infusion delivery or pump stoppage, posing a risk to patient safety.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the pump from active patient use immediately.
- Transfer infusion to another pump if therapy is ongoing.
Verify the Reported Error and Behavior
- Power on the pump and attempt to reproduce the error.
- Observe when the error occurs (startup, priming, or during infusion).
- Listen for abnormal motor behavior.
Check Administration Set Installation
- Verify a Baxter-approved administration set is installed.
- Ensure tubing is properly seated in the pumping channel.
- Confirm cassette is fully latched.
Inspect for Obstruction or Free Flow Conditions
- Check tubing for kinks, occlusions, or clamps.
- Ensure the line is not completely unrestricted (free flow).
Check Pump Channel and Door Mechanism
- Inspect for debris, residue, or physical damage.
- Ensure the pump door closes completely and latches securely.
Power Cycle the Device
- Turn the pump off, wait 10–15 seconds, then restart.
Test with a Known-Good Administration Set
- Install a new, known-good set.
- Perform a basic infusion test.
Evaluate for Intermittent vs Persistent Fault
- Run a short infusion cycle.
- Monitor for recurrence of Error 115.
If the Problem Persists
If Error 115 continues after verifying setup and performing external checks:
- External causes have been ruled out
- Internal motor control or sensor feedback failure is likely
Remove the device from service, label it as Out of Service, and send for repair or bench evaluation.
Clinical Use Tip
Never troubleshoot on an active patient. Always transfer the infusion to a backup pump before evaluating a device with motor-related errors.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 115 Sensor disparity (fast); infusion stopped during use."
Cause
What was observed during troubleshooting.
Example:
"Motor overspeed condition likely due to internal sensor or control fault after external setup issues were ruled out."
Resolution
What action was taken.
Example:
"Removed 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
Motor speed-related errors indicate a loss of precise infusion control. Always rule out setup and tubing issues first, but escalate quickly when faults persist to ensure patient safety and reliable device operation.
That is successful troubleshooting.
