What This Guide Helps With
Troubleshooting lockouts that will not engage or release because of control selection, power, button condition, configuration, connections, or control-system faults.
Step-by-Step Troubleshooting
1. Ensure Patient Safety and Prevent Unintended Motion
A lockout that will not engage can allow unintended bed movement, while a lockout that will not release can prevent required positioning.
Notify clinical staff. Move the patient to another verified bed if safe care depends on the affected motion or patient-control restriction. Do not leave unreliable controls accessible to a confused or high-risk patient.
Expected outcome: The patient is protected from unintended movement or loss of required positioning.
2. Confirm the Exact Lockout Problem
Determine whether:
A lockout will not engage.
A lockout will not release.
The indicator changes but the function remains locked or unlocked.
Only patient controls are affected.
One motion or all motions are affected.
The condition is constant or intermittent.
The issue occurs from one caregiver control location or all locations.
Expected outcome: The failed lockout and its actual effect on bed operation are clearly identified.
3. Verify Bed Power and Stability
Confirm that the bed is connected to verified AC power and remains powered without resets.
Check battery status if the lockout behavior changes when unplugged.
Expected outcome: Stable power is present. A power or reboot issue is corrected before evaluating the lockout system.
4. Confirm the Correct Control Sequence
Use the normal user-accessible caregiver controls to engage or release the intended lockout.
Confirm that the correct function was selected and that the control was operated as intended. Do not enter unauthorized service menus or attempt undocumented button combinations.
Expected outcome: The lockout changes state normally. If operator selection caused the issue, verify operation with clinical staff and stop troubleshooting.
5. Verify the Actual Function, Not Only the Indicator
After engaging the lockout, briefly test the affected patient control. Then release the lockout and test again.
Perform motion testing without a patient when practical and keep the movement path clear.
Expected outcome:
When locked, the affected patient control does not operate the function.
When unlocked, normal operation returns.
The indicator accurately matches the actual lockout state.
6. Compare Caregiver Control Locations
When more than one caregiver control location is available, attempt the same lockout from another location.
Expected outcome:
If one location works, the problem is isolated to a control panel or connection.
If all locations fail, continue evaluating broader configuration or control-system causes.
7. Inspect the Lockout Controls
Inspect the affected buttons and control panel for:
Sticking, recessed, cracked, or damaged buttons.
Fluid residue or contamination.
Impact damage.
Labels or covers interfering with button travel.
Intermittent response when pressed normally.
Do not pry around buttons or apply liquid directly to the panel.
Expected outcome: The control surface is clean, dry, undamaged, and responds normally.
8. Inspect Accessible External Connections
With the bed removed from patient use, inspect externally accessible control cables and connectors for looseness, pinching, contamination, or damage.
Pay attention to wiring near side-rail pivots and moving frame sections.
Expected outcome: External connections are secure. If reseating restores lockout operation, move the side rail through its normal positions and repeat testing.
9. Check for Conflicting Settings or Modes
Confirm whether another approved user setting, therapy mode, emergency function, or control state could be overriding the expected lockout behavior.
Review approved facility and manufacturer information without changing protected configuration.
Expected outcome: No conflicting approved operating condition explains the behavior. An authorized setting correction restores normal lockout function when applicable.
10. Test All Related Lockouts
After correcting the issue, test the affected lockout and other related patient-control lockouts.
Confirm that each lockout engages, blocks the intended function, releases correctly, and displays the proper status.
Expected outcome: Lockout behavior is reliable and matches the indicators. Troubleshooting can stop.
11. Escalate an Unresolved Lockout Failure
Remove the bed from service if a required lockout cannot be trusted, remains stuck, changes intermittently, or does not match the displayed status.
Label the bed Out of Service and send it for bench evaluation.
Expected outcome: A bed with unreliable control restriction is not returned to patient use.
If the Problem Persists
Power, correct control sequence, actual lockout behavior, control-panel condition, accessible connections, and approved operating modes have been evaluated. The remaining cause may involve the caregiver control panel, side-rail network, internal wiring, control electronics, software, or approved configuration.
The bed should be removed from service, labeled Out of Service, and evaluated using appropriate Stryker documentation and approved test equipment. Repair or configuration should be performed only by qualified personnel. Verify every related lockout, indicator, patient control, and caregiver override before return to service.
Knowing when to stop external troubleshooting and escalate is proper troubleshooting.
Clinical Use Tip
Test the patient control after applying a lockout; an illuminated lockout indicator alone does not prove the function is actually disabled.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Nursing reported that the InTouch head-motion lockout indicator was on, but the patient control still raised the head section."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found sticky residue preventing the caregiver lockout button from completing a reliable input."
Resolution
What action was taken.
Example:
"Clinical Engineering cleaned the external control surface using an approved method and verified that the lockout engaged, blocked patient head motion, released correctly, and matched the indicator."
Helpful Details to Include (If Known)
- Lockout or control function affected.
- Whether it would not engage or release.
- Indicator state versus actual function.
- Patient and caregiver controls tested.
- AC and battery status.
- Control-panel damage or contamination.
- External connection condition.
- Conflicting mode or setting observed.
- Intermittent behavior during side-rail movement.
- Final lockout and control test results.
Final Thought
Protect the patient from unintended motion, test actual lockout behavior rather than trusting the indicator alone, rule out external controls and settings, and escalate any inconsistent restriction function.
That is successful troubleshooting.
