Stryker S-Series
Stryker · Model S-Series
Equipment management system. With a redesigned user interface and a compact, fully customizable system, it has never been easier to manage services and maneuver equipment.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
A powered bed function will not run
HighSymptoms: Head, knee, height (Hi-Lo) or Trendelenburg will not move from the siderail or caregiver controls.
Root cause: Failed linear actuator, a control-board fault, a capacitive touch-control fault (subject of an S-Series recall), or a pinched / damaged control cable.
Brake / steer (electromagnetic brake) fault
HighSymptoms: Bed will not brake or release, drifts, or the brake pedal / control is unresponsive - the rotational electromagnetic brake is subject of an S-Series recall.
Root cause: Electromagnetic brake actuator, its control, or worn brake linkage.
Bed-exit / scale system fault
MediumSymptoms: Bed-exit alarm false-triggers or fails to trigger, weight reads implausibly, will not zero.
Root cause: Load-cell drift or damage, or a scale-control fault.
Battery back-up fault
MediumSymptoms: Bed functions and alarms do not work during a power interruption, battery-fault indicator.
Root cause: Aged back-up battery or a charger fault.
Siderail / control-panel fault
LowSymptoms: Siderail latch loose, or the integrated control panel unresponsive / cracked.
Root cause: Worn siderail latch or a damaged control panel.
Electrical-safety test values missing (recall)
MediumSymptoms: Bed shipped without documented electrical-safety test values.
Root cause: Manufacturing documentation gap - subject of a Stryker recall; perform and document an electrical-safety test before use.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: A powered function is dead
- Confirm the bed is plugged in and the battery is charged, and any lock-out for that function is off.
- Try the function from both the siderail and the caregiver / foot controls to isolate the control from the actuator.
- Check the control cable / harness for pinch damage along the articulation.
- Confirm the S-Series capacitive-touch recall corrective action has been applied.
- Replace the actuator or control board as isolated, then load-test the function.
Symptom: Brake will not hold or release
- Test the brake / steer from the pedal and any electronic control.
- Check the electromagnetic brake energises and de-energises on command.
- Inspect the brake linkage and casters for wear or debris.
- Confirm the brake-related recall corrective action has been applied.
- Replace the brake actuator if it will not hold the bed on a slope.

The hydraulic jack assemblies (PN: 0753-002-101, 0753-002-070, 0753-002-001, and 0753-002-001) were manufactured using the incorrect oil. The oil used does not contain the same wear resistance additives as the specified oils and therefore its use increases the potential for wear which may cause a leak event or jack drift. Testing was done to evaluate the jacks with incorrect oil and leak events we
