Zimmer ATS 1500
Zimmer · Model ATS 1500
Indicated to temporally occlude blood flow in a patient’s extremities during surgical procedures on those extremities Tourniquets have been found useful in producing a bloodless operating field in surgical procedures involving the extremities.

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.
Will not reach or hold set cuff pressure
HighSymptoms: Pressure droops during a case, will not inflate to setpoint, leak alarm.
Root cause: Internal pump / compressor wear, a solenoid-valve fault, or a leak in the tubing / cuff / connectors.
Pressure inaccuracy / calibration drift
HighSymptoms: Displayed pressure differs from an independent gauge - patient-safety critical.
Root cause: Pressure-transducer drift or a calibration fault.
Dual-channel / bilateral fault
MediumSymptoms: One channel will not regulate independently, cross-talk between channels.
Root cause: Channel solenoid / transducer or a manifold fault.
Alarm / timer fault
MediumSymptoms: Inflation-time alarm not sounding, timer wrong.
Root cause: Alarm / timer board fault - a safety function.
Tubing / connector / cuff fault
MediumSymptoms: Leak at the connector, cuff will not hold.
Root cause: Worn tubing, connectors, or a damaged cuff.

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: Will not hold set pressure
- Fit known-good tubing and a known-good cuff.
- Occlude the outlet and confirm the pump holds pressure.
- Check the solenoid / regulator valve.
- Verify displayed pressure against a calibrated reference gauge across the range.
- Rebuild / replace the pump, valve or transducer as isolated.
Symptom: Pressure reads inaccurately
- Tee in a calibrated gauge and compare at several set pressures.
- Run the calibration procedure per the service manual.
- Confirm both channels on a dual unit.
- Confirm the inflation-time alarm sounds.
- Do not use the tourniquet clinically until pressure accuracy is confirmed.
