英文名称：Safety of machinery — Evaluation of fault masking serial connection of interlocking devices associated with guards with potential free contacts

发布日期：2015-11

标准范围

This Technical Report illustrates and explains principles of fault masking in applications where multipleinterlocking devices with potential free contacts (B1 to Bn) are connected in series to one logic unit(K) which does the diagnostics (see Figures 1 to 7). It further provides a guide how to estimate theprobability of fault masking and the maximum DC for the involved interlocking devices. This TechnicalReport only covers interlocking devices in which both channels are physical serial connections.This Technical Report does not replace the use of any standards for the safety of machinery.The goals of this Technical Report are the following:— guidance for users for estimation of the maximum DC values;— design guidance for SRP/CS.
