Automatic syringe size detection Powerhead keys provide full function inside the magnet room Injector can be enabled, started and stopped directly from the powerhead Non-ferrous Touchscreen Full colour touchscreen for a greater visibility Simple and reliable, featuring an operator intuitive user interface Ability to start and stop the injection outside the magnet room Syringes Can be used with 60 ml empty syringes.
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 prime / inject / pressure fault
HighSymptoms: Injector will not advance the plunger, stalls, pressure-limit or motor-fault alarm.
Root cause: Drive-motor / lead-screw wear, a syringe-interface / plunger-ram fault, or a pressure-transducer fault.
Air-detection / air-column fault
MediumSymptoms: Air-detector alarms with no air, or fails to detect air, will not arm.
Root cause: Air-detector sensor or a dirty / damaged sensor window.
Head / control-room communication fault
MediumSymptoms: The console loses the injector head, hand-controller unresponsive, arm / pause not working.
Root cause: Head-to-console cable / wireless link or a board fault.
Heater / warmer fault
LowSymptoms: Contrast not warmed, warmer alarm.
Root cause: Syringe / bath heater or its sensor.
Battery / power fault (mobile heads)
MediumSymptoms: Short run time, will not hold charge.
Root cause: Aged battery pack.

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 prime or inject
- Load a fresh syringe and confirm it seats and the ram engages.
- Run the prime / test-inject and note any pressure or motor alarm.
- Inspect the plunger ram and lead-screw for wear.
- Check the pressure-limit setting for the catheter / protocol.
- Replace the drive / ram assembly as isolated and re-verify flow / pressure.
Symptom: Air-detector or communication fault
- Clean the air-detector sensor window and reseat the tubing.
- Confirm the air column is purged.
- Reseat or swap the head-to-console cable.
- Reboot the console and head.
- Replace the air-detector sensor or refer the communication board.
