Prompt

You are a Principal In Vitro Diagnostics (IVD) Systems Engineer and Medical Localization Auditor specializing in laboratory hematology/biochemistry automation and regulatory compliance (ISO 13485 / IEC 62304). Evaluate the following raw service manual excerpt from an automated hematology analyzer. Perform three distinct tasks with absolute technical rigor: --- ### RAW SOURCE INPUT: "SECTION 4.3.2: SAMPLE ASPIRATION & DILUTION MODULE - ERROR CODE E-402 (SYRINGE MOTOR STALL & APERTURE CLOGGING) Condition: The 250 µL precision ceramic syringe motor reports step-loss during RBC/PLT dilution cycle. Simultaneously, the differential pressure sensor across the impedance counting aperture (internal diameter: 70 µm) reads >120 kPa (nominal baseline: 45–55 kPa), indicating a hard protein clot or sheath fluid backflow. Service Interventions: 1. Disconnect high-voltage pinch valve PV-04 (solenoid coil: 24V DC, 8W). 2. Execute automated backflush protocol using 5% sodium hypochlorite enzymatic deproteinizer at 42°C. Warning: Do not exceed 60 seconds immersion to prevent Viton O-ring degradation. 3. Check optical flow cell alignment: Adjust micrometric screw S2 until photodiode pre-amplifier voltage stabilizes at 3.3V ± 0.05V DC under blank diluent flow. (Note: In revision C units, valve PV-04 is normally closed at 0V, but software parameter P-88 overrides this to normally open when maintenance door switch SW-1 is engaged)." --- ### YOUR TASKS: 1. Technical Localization & Auditing (Target: Turkish): - Translate and audit the technical instructions into industry-grade Turkish suitable for an authorized field service engineer (FSE) manual. - Preserve critical engineering phrasing (e.g., syringe motor stall, impedance counting aperture, backflush protocol, pinch valve, blank diluent). Avoid generic literal machine translations. - Highlight any high-priority technician safety warnings and component risk factors with standard IVD service notation (DİKKAT / UYARI). 2. Structured Data Extraction (MCP / Automation Ready): - Extract the operational service data into a strictly valid, minified JSON object matching this schema: { "fault_code": "string", "subsystem": "string", "nominal_parameters": {"metric": "string", "expected_range": "string"}, "service_steps": [{"step": 1, "action": "string", "voltage_or_spec": "string", "risk_warning": "string"}], "critical_components": [{"id": "string", "type": "string", "spec": "string"}] } - Provide a corresponding clean Python Pydantic (v2) model that validates this extracted JSON schema. 3. Anomaly & Conflict Detection (Engineering Reasoning): - Analyze the text for any potential electromechanical or software logic conflict in the excerpt (specifically reviewing the behavior described for Revision C / valve PV-04 / SW-1 vs electrical safety). - State clearly if this creates a latent diagnostic loop or hazard, and explain how a service technician should isolate the variable before applying power. Constraints: Do not hallucinate safety tolerances. Keep responses structured, free of filler text, and strictly adhere to the requested schema.
