In industrial automation, the reliability of control systems is critical to ensuring smooth operations, safety, and long-term performance. At NS Controls, we take a structured approach to quality control with two key processes: Final Inspection and Testing (FIT) and Factory Acceptance Testing (FAT). These steps ensure every panel, rack, or system we build meets the highest industry standards before leaving our facility.
What is FIT (Final Inspection and Testing)?
Before a project moves to FAT, it must first pass FIT—our internal quality assurance process. During FIT, our team follows a detailed inspection procedure to verify that every component is installed correctly and meets our high standards for functionality and safety.
Key steps in our FIT process include:
Visual Inspection – Checking connections, verifying components, ensuring nameplates and tags are in place, and confirming the structural integrity of the installation.
Ground Check – Conducting a full continuity check to verify proper grounding for all components.
Power-Up Testing – Following strict safety protocols to energize and test circuits, verifying voltage readings, and ensuring proper system operation.
Rework & Re-Testing – If any issues arise, they are documented on a punch list, addressed by our production team, and re-tested to ensure full compliance.
Once a project successfully passes FIT, it is ready for customer review during FAT.
What is FAT (Factory Acceptance Testing)?
FAT is the final step before delivery, allowing customers to review and verify that the system meets all functional and operational requirements. At NS Controls, we welcome customers to attend FAT in our controlled facility, providing them with confidence in their investment before installation.
Our FAT process includes:
Functional Testing – Simulating real-world operating conditions to confirm system performance.
Customer Walkthrough – Demonstrating system operation and addressing any final questions.
Final Approval & Documentation – Ensuring all punch list items are resolved before the system is shipped.
Why FIT & FAT Matter
By performing rigorous FIT and FAT testing in our climate-controlled facility, NS Controls guarantees that every system leaving our shop is safe, compliant, and ready for seamless integration. This structured approach minimizes on-site issues, reduces downtime, and provides our customers with peace of mind.
