# Industrial Specification: Constraint Validator

## 1. Technical Definition
A component within a Constraint Handler system that verifies whether operational parameters meet predefined limits or conditions.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1000 bar at 0-150°C**. Failure boundary: **Pressure sensor membrane rupture at 1200 bar or 180°C**, Mechanism: **Yield strength exceedance of 316L stainless steel membrane (205 MPa at 20°C, reduced to 172 MPa at 180°C due to thermal softening)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Electromagnetic interference from adjacent 480V AC motor starters | 8 | Signal comparator IC latch-up at 2.1V threshold deviation | Shielded twisted-pair cabling with ferrite cores and 0.1μF decoupling capacitors at IC power pins |
| Condensation ingress through IP65-rated housing at 95% RH with 15°C thermal cycling | 8 | PCB trace corrosion causing 10kΩ resistance increase on feedback loops | Conformal coating with 50μm acrylic layer and silica gel desiccant in sealed compartment |

- **Caution**: 

### Q: What is the primary function of a Constraint Validator in machinery manufacturing?
**A**: The Constraint Validator continuously monitors operational parameters against predefined safety and performance limits, triggering alerts or shutdowns when conditions exceed acceptable ranges to prevent equipment damage and ensure operator safety.

### Q: How does the Constraint Validator integrate with existing machinery control systems?
**A**: It connects via the Input Interface to receive real-time data from sensors and controllers, processes this through its Processing Unit, and uses the Output Relay to communicate with PLCs, SCADA systems, or directly control machinery functions when limits are breached.

### Q: What maintenance is required for the Constraint Validator's electronic components?
**A**: Regular inspection of circuit boards for corrosion or damage, verification of relay functionality, and firmware updates are recommended. The plastic housing provides IP-rated protection, but periodic cleaning and environmental checks ensure long-term reliability in industrial settings.
