Zimmer ATS 3000
Zimmer · Model ATS 3000
Innovative Limb Occlusion Pressure(LOP) feature. Uses ambient air. Uses electronic and microprocessor regulated pressure. Self-Check Calibration automatically checks the accuracy of the machine calibration each time the unit is powered on. Cuff Alert alerts the user of cuff status when an attempt is made to set the machine on standby. Cuff Lockout feature prompts the user to confirm the deflation command during bilateral or IVRA procedure in order to reduce complications due to sudden cuff deflation of the second cuff.
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.
Cuff will not inflate
HighSymptoms: Main or second cuff does not pressurise on command.
Root cause: Membrane panel not seated, pump not plugged in, a stuck-open deflate valve, or a valve-driver / harness fault.
Cuff will not deflate
HighSymptoms: Cuff stays pressurised when deflation is commanded.
Root cause: Deflate valve stuck shut, or a valve-driver / harness fault.
Pressure inaccurate / self-check calibration fault
HighSymptoms: Displayed pressure disagrees with a reference, self-check on power-up fails.
Root cause: Pressure transducer drift or a control-board calibration fault.
Cuff / hose leak detected
MediumSymptoms: System repeatedly tops up the cuff, leak alarm, set pressure not held.
Root cause: Cuff bladder or hose leak, or a loose positive-locking connector.
Runs on battery / short backup time
MediumSymptoms: Battery indicator lit or flashing during normal use, unit dies on transport.
Root cause: Aged backup battery or a charger fault (battery is for power-loss / transport only).
Out-of-box or intra-operative failure (recall history)
HighSymptoms: Unit fails at first use or mid-procedure.
Root cause: Subject of a Zimmer A.T.S. 3000 voluntary removal for out-of-box and intra-operative failures - check the unit's serial against the recall notice.

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: Cuff will not inflate
- Confirm the membrane panel is fully seated at its connector (P8 on the ATS 3000).
- Check the internal tubing is not pinched and all pneumatic connectors are mated.
- Confirm the pump is plugged in and its harness is undamaged.
- Check the deflate valve is not stuck open and the valve harness is intact.
- Run the functional and calibration checks after any repair.
Symptom: Pressure reading suspect
- Power-cycle and let the self-check calibration run.
- Tee a calibrated reference manometer to the cuff port.
- Compare at several set pressures across the range.
- If out of tolerance, recalibrate per the service manual or replace the transducer.
- Re-verify against the reference and record the date.

Zimmer is conducting a voluntary removal of some Zimmer A.T.S. 3000 tourniquets after receiving complaints of both out-of-box failures and failures during surgical procedures on some of the affected units. During failure the unit will alarm, lock into a non-operational mode, and the display screen will go blank. Based on investigation, this problem appears to be due to a counterfeit chip on the
