What This Guide Helps With
This guide helps troubleshoot Error 0x1190 Load Beam 4 Fault on a Hillrom Centrella Smart+ hospital bed. This error indicates a scale system fault that can cause inaccurate, unstable, or unavailable patient weight readings.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the bed from active patient weighing use.
- If patient weight is needed, use an alternate verified scale or functioning bed.
- Do not rely on the bed scale while the error is present.
Verify the Reported Error and Behavior
- Power on the bed and confirm Error 0x1190 is displayed.
- Check whether the error appears at startup or during weighing.
- Observe whether the weight reading is missing, unstable, or clearly incorrect.
Check for Obstructions Under the Bed
- Inspect beneath the bed frame, especially around the scale and load beam areas.
- Look for cords, linens, debris, equipment, or objects touching the frame or base.
- Ensure nothing is wedged between the bed and floor.
- Confirm the bed frame is free-floating with no external contact affecting weight readings.
Verify Bed Position and Environment
- Place the bed on a flat, level surface.
- Confirm all casters are evenly contacting the floor.
- Engage the brakes properly.
- Make sure the bed is stable and not positioned against walls, equipment, or furniture.
Remove Excess or Uneven Load
- Remove heavy equipment hanging from one side of the bed when possible.
- Reposition accessories evenly across the bed.
- Check for abnormal loading near the corner associated with Load Beam 4.
Inspect External Components and Frame Condition
- Look for bent frame sections near the bed corners.
- Check for signs of impact, damage, or twisting.
- Inspect visible external cables only if accessible without disassembly.
- Do not open covers or perform internal repairs during clinical troubleshooting.
Power Cycle the Bed
- Turn the bed off if applicable.
- Disconnect the bed from AC power.
- Wait 30–60 seconds.
- Reconnect power and restart the bed.
- Check whether the error clears after reboot.
Re-test Scale Function
- After external checks are complete, attempt to use the scale function again.
- Confirm the weight reading is stable and reasonable.
- Verify Error 0x1190 does not return.
If the Problem Persists
If Error 0x1190 remains after checking for obstructions, bed position, uneven loading, visible damage, and power reset, external causes have been ruled out.
The issue likely indicates a failed, damaged, or drifting Load Beam 4 sensor or related scale system fault.
Remove the bed from service, label it Out of Service, and send it for repair or bench evaluation. Load beam evaluation or replacement may be required.
Clinical Use Tip
Never troubleshoot on an active patient when scale readings are needed for care decisions. Move the patient to a backup device or obtain weight using another verified method first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Hillrom Centrella Smart+ bed displaying Error 0x1190 Load Beam 4 Fault with inaccurate or unavailable weight readings."
Cause
What was observed during troubleshooting.
Example:
"Obstructions, bed position, uneven load, and external damage were checked. Fault persisted, indicating likely Load Beam 4 sensor failure."
Resolution
What action was taken.
Example:
"Removed bed from service, labeled Out of Service, and sent for repair for load beam evaluation or replacement."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Scale system errors should be handled carefully because inaccurate patient weight can affect clinical decisions. Rule out simple external causes first, then remove the bed from service when the fault persists.
That is successful troubleshooting.
