Automatic change to manual system during failure of compressed air No battery needed Maintenance free Can be used at any time even without compressed air.
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 pressure will not hold
HighSymptoms: Set pressure decays, needs frequent top-up, limb pressure unreliable.
Root cause: Cuff bladder or tubing leak, a loose connector, or a worn internal valve.
Pressure reading inaccurate
HighSymptoms: Displayed pressure differs from a reference, drift over time.
Root cause: Pressure transducer drift.
Will not inflate from compressed air
MediumSymptoms: No or slow inflation on the pneumatic supply; unit falls back to the manual system.
Root cause: Supply pressure low, inlet filter blocked, or an internal solenoid valve fault.
Timer / alarm fault
MediumSymptoms: Inflation timer not counting or not alarming at the set time.
Root cause: Timer or audible-alarm fault.

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 hold pressure
- Inflate a test limb/mandrel to a set pressure with the cuff clamped and watch for decay.
- Check the cuff, bladder, tubing and connectors for leaks.
- Replace the leaking cuff or tubing.
- If the machine side leaks, refer for internal valve service.
- Re-test the pressure hold on each channel.
Symptom: Pressure reading suspect
- Tee a calibrated reference gauge to the cuff line.
- Compare at low, mid and high set pressures.
- If the error exceeds the manufacturer's limit, refer for transducer calibration/replacement.
- Re-verify against the reference.
- Record the calibration date.
