Reliable Designs
Once a machine risk assessment is complete, DAK Machine Safety provides complete engineering design services to bring each safety solution from concept to execution. We specialize in developing fully integrated mechanical, electrical, pneumatic, and hydraulic designs that align with safety standards and your plant operations.
Our design service bridges the gap between hazard identification and reliable solutions implementation—ensuring that the risk reduction recommendations are properly designed, engineered, programed, documented, and ready for fabrication and installation.
What’s Included in Our Engineering Design Package-
Electrical Design & Schematics
We design UL508A-compliant panels and electrical schematics that define how the safety components interface with your machines. These include:
- Safety PLC wiring diagrams
- Emergency stop circuits
- Safety relay/controller integration
- Two-hand control, interlock, light curtain, and scanner circuits
Pneumatic & Hydraulic Circuit Design
Where applicable, DAK provides pneumatic and hydraulic schematics to ensure safe energy control in motion-based systems. This includes:
- Integration of monitored dump valves
- Pressure sensing logic for safe motion
- Cylinder lockout circuits
- Redundant valve arrangements for safety-rated motion
Safety Matrix (Cause & Effect)
A detailed Safety Function Matrix documents every input, logic condition, and output related to the machine’s safety system:
- Safety device inputs (e.g., light curtains, e-stops)
- Logic and reset requirements
- Controlled stopping and locking mechanisms
- Restart and fault diagnostics
This is an essential tool for both programming and future validation.
Mechanical Guarding Design
Our team creates custom mechanical guarding drawings based on the physical layout and operational needs of your equipment:
- Fixed perimeter guards
- Interlocked access panels
- Adjustable or removable guarding assemblies
- Operator interface considerations (ergonomics, access, visibility)
Designs are delivered in native 3D CAD or 2D format with clear fabrication specs
Bill of Materials (BOM)
We supply a comprehensive BOM listing all components needed for the safeguarding system—panel parts, sensors, guards, solenoids, cable types, and more—so procurement and budgeting are clear and streamlined.
Safety PLC / Safety Controller Programming
DAK engineers develop and validate custom logic for:
- Siemens, Allen-Bradley, Pilz, Sick, Yaskawa and others
- Safety-rated interlocks, muting, jog, and zone control
- HMI Diagnostic programing as well for ease of status monitoring
- Networking into existing PLC or a switch for remote troubleshooting, if required
Standards Compliance
All designs follow the applicable machine safety standards:
- ANSI B11.19 – Safeguarding system performance
- ISO 13849 / IEC 62061 – Functional safety of control systems
- UL 508A – Panel construction and safety
- NFPA 79 – Industrial machinery electrical standard
- OSHA 1910 Subpart O – Machine guarding
