Physiomed Physiotherm-S
PHPhysiomed · Model Physiotherm-S
Operating frequency: 27.12 MHz; pulse frequency 10-300 Hz; pulse duration: 200-600 µs Pulsed and continuous energy output for thermal and a thermal applications Capacitor field method for uniform heating of all the tissue layers Coil field method (optional) for selective treatment of tissue with good conductive structures, such as connective tissue and muscles HF power: 400 W (continuous mode)/1000 W (pulsed mode), infinitely variable Matching function for steady development of heat and prevention of over dosage Extremely well-shielded, high-frequency connection cables Easily adjustable supporting arms for exact electrode placement Smooth running castors for good mobility.
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: Fluid / blood / blanket not reaching target temperature
- Confirm the correct programme / set for the fluid type and flow rate.
- Check both heater plates (or the water bath) warm evenly.
- Verify the output temperature against an independent reference at a representative flow.
- Replace the temperature sensor if it disagrees.
- Replace the heater plate / control assembly if output is still low.
Symptom: Over-temperature alarm / shutdown
- Let the unit cool and restart.
- Compare the displayed temperature to an independent reference.
- Check for an extreme flow-rate change during use (fluid warmers).
- Replace the temperature sensor / control board as isolated.
- Confirm stable control across the range before returning to service.
Symptom: Low airflow / blower fault (forced-air) or low water flow (water blanket)
- Replace the intake / HEPA filter (forced-air) or top up and de-air the reservoir (water).
- Check the hose for kinks or splits and confirm the correct blanket type.
- Inspect the blower / circulation pump and impeller.
- Replace the blower / pump if flow is still low.
- Confirm delivered air / water temperature and flow after repair.
