Technical Handbook: Basic Knowledge of Machine Safety and Disconnect + Trap Key

Achieving Cat4 and PLe without complex calculations - "Disconnection Switch + Trap Key Safety Measures Handbook"

Transforming the safety level of manufacturing sites from "relying on education" to "design-based" — This handbook explains how to conduct risk assessments and build safety controls equivalent to Cat4 and PLe in a simple manner, centered around ISO12100, ISO13849, and ISO14119. Readers can quickly understand everything from visualizing accident factors to countermeasures through illustrated flows and real data. In the second part, we cover power interlocks using IEC60947-3 compliant disconnect switches and Fortress trap keys, detailing the steps to upgrade existing equipment without additional wiring, along with case studies from four industries: steel, cement, paper, and more. It eliminates the need for calculations to achieve Cat4 and PLe, resolving the concerns of design and maintenance engineers about "overly complex PL calculations." With over 16 pages and more than 30 diagrams, supervised by the Kraus & Naimer safety team, this handbook is filled with practical insights that can be immediately used for in-house training materials on machine safety and proposal creation.
