It is necessary to install point-of-operation guarding devices, such as safety light screens and/or hard guards, to protect personnel from hazardous machinery. Failure to install point-of-operation guards on hazardous machinery can result in a dangerous condition which could lead to serious injury or death.

Overview An Emergency Stop Safety Module is used to increase the control reliability of an emer- ES-FA-9AA ES-FA-11AA gency stop circuit. As shown in the hookup drawings, the models ES-FA-9AA and ES- FA-11AA E-Stop Safety Modules are designed to monitor a 1-channel or 2-channel E- stop switch. A 2-channel E-stop switch has two electrically isolated contacts. Power ON LED WARNING: Safety Categories The level of safety circuit integrity can be greatly affected Channel 1 Active LED by the design and installation of the safety devices and Channel 2 Active LED the means of interfacing of those devices. A risk as- sessment must be performed to determine the appro- priate safety circuit integrity level or safety category as described by ISO 13849-1 (EN 954-1) to ensure the expected risk reduction is achieved and all relevant regulations and standards are complied with. Figure 1. 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 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 the most stringent, Category 4. In the United States, the typical level of safety circuit integrity has been called control reliability. Control reliability typically incorporates redundant control and self-checking circuitry and has been loosely equated to ISO 13849-1 Categories 3 and 4 (see CSA Z432 and ANSI B11.TR4). If the requirements described by ISO 13849-1 (EN954-1) are to be implemented, a risk assessment must first be performed to determine the appropriate category, in order to ensure that the expected risk reduction is achieved. This risk assessment must also take into ac- count national regulations, such as U.S. control reliability or European C level standards, to ensure that the minimum level of perform- ance that has been mandated is complied with. 2 www.bannerengineering.com - tel: 763-544-3164 P/N 060606 Rev.
