Factory Acceptance Testing (FAT)

Validating Performance Before It Reaches Your Floor

The most critical phase of any automation project is the moment the software meets the hardware. At HF Controls, we provide comprehensive Factory Acceptance Testing (FAT) at our dedicated manufacturing facility. This process allows us to prove that every aspect of your new system operates exactly as intended before it ever leaves our floor.

We utilise FAT to minimise on-site installation time and eliminate the risk of unforeseen technical issues during commissioning. We provide both Full and Partial testing regimes, tailored to the complexity of your specific project.

Proving System Logic through Simulation

Our FAT services range from basic configuration checks to high-level plant simulations. By creating a “digital twin” or using simulation hardware, we can replicate your plant’s operational environment within our workshop.

• Basic Setup & Operation: Verifying the physical build, point-to-point wiring, and basic power-on logic.
• Complex System Simulation: Proving complex operational sequences and multi-device communication.
• Fault Condition Analysis: We don’t just test if it works; we test how it fails. By simulating sensor failures, emergency stops, and power loss, we ensure your system responds safely and predictably in every scenario.
• Software Validation: Fine-tuning HMI screens and SCADA interfaces with your operators present, ensuring the user experience is optimized before go-live.

Flexible Testing Regimes

We understand that every project has different requirements for verification. We offer flexible testing levels to suit your schedule and budget:

• Full Factory Acceptance Testing: A complete, end-to-end “dry run” of the entire system. This is the gold standard for complex production lines and critical infrastructure, involving a rigorous checklist of every functional requirement.
• Partial Factory Acceptance Testing: Focused testing on specific modules or newly integrated components. This is ideal for system upgrades or when only a portion of the control architecture has been modified.

Why FAT is Essential for Your Project

Investing in a thorough FAT process provides significant long-term benefits for plant owners and project managers:

• Zero On-Site Surprises: Identifying and resolving logic or hardware issues in our controlled workshop environment is significantly faster and cheaper than doing so on a live production floor.
• Reduced Commissioning Time: Because the system has already been “proven,” the on-site installation and final handover are streamlined, reducing downtime for your facility.
• Operator Familiarization: FAT provides an excellent opportunity for your key operators to interact with the system early, gaining confidence and providing feedback in a low-pressure environment.
• Full Documentation: Every FAT concludes with a detailed report and signed-off test sheets, providing a clear audit trail for your quality and safety compliance.
