Safety of machinery. Evaluation of fault masking serial connection of interlocking devices associated with guards with potential free contacts Ingestion-build-63436 Do not use in a1 Scope This Technical Report illustrates and explains principles of fault masking in applications where multiple interlocking 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 the probability of fault masking and the maximum DC for the involved interlocking devices. This Technical Report only covers interlocking
