Features and Terminals Safety Circuit Integrity and ISO 13849-1 (EN954-1) Safety Circuit Principles Safety circuits involve the safety-related functions of a machine that minimize the level of risk of harm. These safety-related functions can prevent initiation, or stop or remove a hazard. A failure of a safety-related function or its associated safety circuit may result in an in- creased risk of harm. The integrity of a safety circuit depends on several factors, including fault tolerance, risk reduction, reliable and well-tried components, well-tried safety principles, and other design considerations. Depending on the level of risk associated with the machine or its operation, an appropriate level of safety circuit performance must be incorporated. ANSI/RIA R15.06 Industrial Robots, ANSI B11 Machine Tools, OSHA 29CFR1910.217 Mechanical Power Presses, and ISO 13849-1 (EN954-1) Safety-Related Parts of a Control System standards provide details of the safety performance levels. Safety Circuit Integrity Levels The safety circuits in International and European standards have been segmented into categories, depending on their ability to maintain their integrity in the event of a failure. The most recognized standard that details safety circuit integrity levels is ISO 13849-1 (EN954-1), which establishes five levels: Categories B, 1, 2, 3, and 4 (most strict). 2 www.bannerengineering.com - tel: 763-544-3164 P/N 122365 Rev.
