Cincinnati Sub-Zero Portable Cold Therapy
Cincinnati Sub-Zero · Model Portable Cold Therapy
Versatile - With a variety of specially designed pads, and options like the automobile adapter, strapping system for back, hip, and knee, CSZ's portable cold therapy system can provide cold therapy wherever and whenever it's needed. Easy to Use - Unlike other units which must be raised to the level of the pad for adequate pumping and taken off the bed bracket for lid access, this portable cold therapy system can be operated from floor level and filled while hanging in place. Reduces pain and the amount of medication needed Reduces edema Accelerates the healing of damaged tissue Promotes blood coagulation.
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.
Motor / actuator / drive will not run or is weak
HighSymptoms: Traction force not applied, CPM carriage will not move or stalls, drive assist weak, motion one direction only.
Root cause: Worn drive motor / leadscrew / actuator, a hand-control fault, or a control-board fault.
Force / range / position inaccuracy
MediumSymptoms: Set traction force or CPM angle not reached, load cell drifts, carriage overshoots or stalls short.
Root cause: Load-cell / position-sensor drift, a potentiometer fault, or a limit-switch fault.
Hand control / patient-control fault
MediumSymptoms: Hand control unresponsive, the patient stop / reverse button does not work.
Root cause: Worn hand control or a damaged cable.
Frame / bearing / cable wear
MediumSymptoms: Rough or noisy travel, play in the carriage, frayed traction cord or rope.
Root cause: Worn bearings / slides or a frayed cable / cord.
Power / battery fault
LowSymptoms: Will not power on, short battery run time.
Root cause: Power supply / fuse or an aged battery.

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: Motor / actuator will not run
- Confirm mains / battery and that any e-stop / patient stop is released.
- Try the hand control and, if fitted, the unit buttons to isolate the control.
- Listen for the drive motor and check the leadscrew is not jammed.
- Replace the hand control, motor or control board as isolated.
- Verify the achieved force / range against a reference after repair.
Symptom: Force or range not reached
- Run the calibration / homing routine.
- Check the load-cell / position sensor and the limit switches.
- Verify with a known weight (traction) or a goniometer (CPM).
- Replace the sensor if it drifts.
- Re-verify and confirm the patient stop works.
