Rigorous industrial equipment testing before shipment protects custom automation projects from costly field delays and budget overruns, which is critical when defects alone cost U.S. discrete manufacturers an estimated $32-$59 billion annually. When unverified machinery hits a plant floor, hidden wiring errors and logic bugs stall commissioning schedules for weeks. Hallfield Controls approaches pre-shipment validation with engineering-first rigor, ensuring every control panel, drive configuration, and software sequence is verified before freight leaves our facility.
In this guide, our team breaks down how structured testing protocols eliminate operational risk and guarantee long-term machine quality.
Custom FAT/SAT vs. Repeat Production Testing
Different project scopes require distinct verification strategies. Custom automation demands custom validation workflows, whereas repeat machine builds require strict, standardized manufacturing execution.
Factory Acceptance Testing (FAT)
Focuses on custom, one-off designs. It validates that new software logic, physical hardware, and process sequences perform to exact customer specifications before shipping.
Repeat Production Testing
Relies on standardized internal work instructions and checklists. It verifies that every repeat build matches the baseline build identically, preventing manufacturing drift over extended production runs.
Site Acceptance Testing (SAT)
Conducted after delivery and installation on the plant floor. It confirms system functionality within the customer’s actual operating environment.
While FAT catches design gaps on brand-new concepts, repeat testing enforces total quality control across high-volume production.
How We Test Custom One-Off Automation Systems
Custom automation carries unique technical risks, which is why our pre-shipment verification follows a rigorous engineering sequence scaled directly to your project requirements. Depending on the complexity of your system and contractual scope, our validation process can encompass this full, end-to-end testing suite:
- Visual & Electrical Inspection: Assemblies undergo visual wiring and component reviews to confirm print accuracy. Every wire tag utilizes page-and-line grid labeling matching electrical schematics.
- Initial Power-Up Checks: Control cabinets are energized in a controlled environment to verify power distribution, fuse ratings, and safety circuit resets.
- Programmer-Led Configuration (As Required): When software and motion control are included, the engineer who authored the software configures VFDs, servo drives, field networks, and PLC logic to test accessible machine functions thoroughly.
- Internal FAT Sign-Off (Customer Optional): When formal testing protocols are requested, our team executes customer-provided FAT procedures internally to pre-verify system performance prior to delivery.
- Witness Testing (Customer Optional): Customers inspect machine operation at our facility, witnessing live sequence execution and signing off on verified compliance.
Streamlining Testing for Repeat OEM Production Runs
Repeat OEM builds demand speed and consistency. Tying up senior engineering staff on routine quality checks slows down delivery schedules. Hallfield Controls utilizes dedicated production teams to execute standardized, 100% procedural testing on repeat orders.
- Standardized Work Instructions: Assembly technicians execute step-by-step power-up, device flashing, and functional checklists for every unit built.
- Specialized Compliance Checks: Specialized testing is conducted and recorded per build, such as Hi-Pot testing for pool-adjacent equipment under specific UL guidelines.
- Continuous Procedure Adaptation: Fringe cases discovered in the field are integrated into production checklists, preventing repeat issues on future builds.
