What This Guide Helps With

This guide helps troubleshoot the SENSOR ERROR 2 alarm on the Cardinal Health Kangaroo OMNI feeding pump. This alarm is associated with force sensor detection, cassette loading issues, sensor contamination, moisture, feeding set problems, or possible pump sensor degradation.

Because this alarm can prevent normal feeding setup or interrupt pump operation, the pump should not be trusted for patient feeding until the cause is corrected and operation is verified.

Step-by-Step Troubleshooting

Ensure Patient Safety First

• If the Kangaroo OMNI is connected to a patient and the alarm prevents feeding, do not continue relying on the pump.
• Stop the feeding according to clinical procedure.
• Place the patient on another verified feeding pump if nutrition delivery must continue.
• Do not troubleshoot the pump while it is actively needed for patient feeding.

Expected: The patient is not dependent on a pump with an unresolved sensor alarm.

Why it matters: A force sensor-related alarm may prevent accurate cassette detection or safe pump operation.

Verify the Reported Alarm and Behavior

• Power on the pump and confirm the exact alarm displayed is SENSOR ERROR 2.
• Note whether the alarm occurs immediately on power-up.
• Check whether it appears after cassette removal, after cassette loading, or intermittently during setup.
• Determine whether the alarm occurs only with one specific feeding set.
• Document whether the pump allows the user to press Continue or restart feeding.

Expected: The SENSOR ERROR 2 alarm is confirmed and the timing is documented.

Why it matters: This confirms a true system-reported sensor condition rather than a general feeding set or loading complaint.

Remove the Feeding Set Cassette

• Remove the cassette from the pump.
• Inspect the cassette area for improper cassette seating.
• Look for formula residue, moisture, dried feeding solution, or debris near the occlusion or force sensor region.
• Inspect the cassette for damaged, warped, or contaminated components.
• Confirm the cassette can be inserted and removed normally without binding.

Expected: The cassette area is free of obvious obstruction or contamination.

Why it matters: SENSOR ERROR 2 is related to force sensor detection, and contamination or pressure on the sensor area can create a false sensor condition.

Clean and Dry the Occlusion Sensor Region

• Clean the occlusion sensor region using the facility-approved cleaning procedure.
• Remove visible formula buildup, sticky residue, or moisture from the cassette bay area.
• Make sure the area is fully dry before reinstalling the feeding set.
• Do not scrape, force, or press hard on the sensor area.
• Do not use sharp objects to clean the sensor region.

Expected: The sensor region is clean, dry, and free of formula buildup.

Why it matters: Moisture or residue can interfere with the pump’s ability to correctly detect force sensor behavior.

Reload the Cassette Correctly

• Reload the cassette carefully and confirm it is seated correctly in the pump.
• Confirm the cassette is fully engaged and not tilted, loose, or partially seated.
• Press Continue if prompted.
• Attempt to restart feeding using an approved test setup or clinical setup as appropriate.

Expected: The cassette loads normally and the SENSOR ERROR 2 alarm clears.

If resolved: Verify pump operation, document the cleaning and cassette reseating, and return the pump to service if no further alarms occur.

Replace the Feeding Set

• If SENSOR ERROR 2 continues, remove the current feeding set.
• Install a new compatible Kangaroo OMNI feeding set.
• Confirm the replacement cassette is not damaged, contaminated, or expired.
• Restart setup and check whether the alarm clears with the replacement set.

Expected: The alarm clears with a new feeding set.

Why it matters: A cassette or feeding set problem can place abnormal pressure on the force sensor area and trigger the alarm.

Check for Physical Damage or Contamination

• Inspect the pump around the cassette bay and sensor area for cracked plastic.
• Look for sticky residue, liquid intrusion, or dried formula contamination.
• Check for bent or damaged cassette contact areas.
• Look for signs the pump was dropped or impacted.
• Confirm there is no difficulty inserting or removing the cassette.

Expected: The pump cassette bay is physically intact and clean.

Why it matters: Damage around the cassette bay can affect sensor alignment and cause repeated force sensor alarms.

Power Cycle the Pump

• Turn the pump off.
• Wait briefly, then power it back on without a cassette installed.
• Observe whether SENSOR ERROR 2 appears immediately on startup.
• If the alarm appears without a cassette or obstruction present, do not continue attempting to use the pump.

Expected: The pump starts without the alarm when no cassette or obstruction is present.

Why it matters: An alarm that appears immediately on power-up may indicate sensor degradation or an internal sensor failure.

Stop When Resolved

• If cleaning, drying, cassette reseating, or feeding set replacement clears the alarm, run a basic operational check before returning the pump to service.
• Confirm the pump powers on normally.
• Confirm the cassette loads correctly.
• Confirm the alarm does not return.
• Confirm feeding can be started using an appropriate test setup.
• Confirm no additional alarms appear.

Expected: The pump operates normally without SENSOR ERROR 2.

If the Problem Persists

If SENSOR ERROR 2 continues after removing the cassette, cleaning and drying the sensor region, reloading the cassette, power cycling the pump, and replacing the feeding set, external and common causes have been ruled out.

A persistent SENSOR ERROR 2 alarm may indicate force sensor degradation or an internal sensor-related pump failure.

Remove the pump from service, label it Out of Service, and send it for repair or bench evaluation. Use a different Kangaroo OMNI pump for patient feeding.

Knowing when to stop is proper troubleshooting.

Clinical Use Tip

Never troubleshoot SENSOR ERROR 2 on an active patient if feeding delivery is interrupted or the pump cannot be trusted. Move the patient to a backup device first, then troubleshoot the pump using an appropriate test setup.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Kangaroo OMNI feeding pump reported SENSOR ERROR 2 alarm during startup or cassette loading and prevented normal feeding setup."

Cause

What was observed during troubleshooting.

Example:
"Occlusion and force sensor region inspected. Cassette area cleaned and dried. Alarm persisted after cassette reload and replacement feeding set, indicating likely internal force sensor degradation or sensor detection failure."

Resolution

What action was taken.

Example:
"Removed cassette, cleaned and dried sensor region, reloaded cassette, pressed Continue, and tested with replacement feeding set. SENSOR ERROR 2 remained. Pump removed from service, labeled Out of Service, and sent for repair evaluation. Alternate pump placed into use."

Helpful Details to Include (If Known)

• Alarm behavior
• Accessories swapped
• Power behavior
• Environmental factors
• Indicator lights
• Final device status

Final Thought

SENSOR ERROR 2 should be treated as a real pump-reported force sensor condition until proven otherwise. Start with the cassette, cleaning, drying, and feeding set replacement, but do not continue using a pump with a repeated sensor alarm. Patient safety, logical isolation, appropriate escalation, and clear CCR documentation are the key parts of successful Clinical Engineering troubleshooting.

That is successful troubleshooting.
