User-defined 150- or 300-cassette capacity configuration. Two levels of password protection for complete instrument and information security.
Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
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.
Alarm to inform of error / processing malfunction
HighSymptoms: An error alarm stops or interrupts a run; the instrument logs the fault in history and calls for operator action.
Root cause: A reagent / paraffin transfer fault, a valve / pump fault, a level or pressure-sensor fault, or a retort / seal fault.
Reagent / paraffin transfer fault
MediumSymptoms: Retort not filling or draining, incomplete exchange, low- / high-level alarm.
Root cause: Worn pump / valve, a blocked line, or a level-sensor fault.
Retort pressure / vacuum fault
MediumSymptoms: Pressure / vacuum not achieved, poor infiltration, seal alarm.
Root cause: Worn retort door seal, a vacuum / pressure-pump fault, or a valve.
Paraffin bath / heater fault
MediumSymptoms: Paraffin not molten or wax too hot, bath-temperature alarm.
Root cause: Bath heater or temperature-sensor fault.
Fume-management / carbon-filter fault
LowSymptoms: Reagent fumes in the room, filter-change overdue.
Root cause: Saturated carbon filter or a fan 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: Error alarm / processing malfunction
- Note the alarm / error code and check the history log.
- Confirm reagent and paraffin levels and that the correct containers are in place.
- Check the retort fills and drains fully and holds pressure / vacuum.
- Inspect the retort door seal.
- Follow the service manual for the specific alarm; replace the pump, valve or seal as isolated.
Symptom: Retort pressure / vacuum fault
- Inspect and replace the retort door seal.
- Run the pressure / vacuum self-test.
- Check the pump and valves.
- Confirm no blocked lines.
- Verify infiltration quality on a control block after repair.
