Safety of machinery. Evaluation of fault masking serial connection of interlocking devices associated with guards with potential free contacts Ingestion-build-63436 sound signals and interactive services

sound signals and interactive services are networking hardware used to connect one network device to other network devices or to connect two or more computers to share printers

PD CLC/TR 62453-51-60 is a result of an analysis and design process to develop standard interfaces to facilitate the development of servers and clients by multiple vendors that need to interoperate seamlessly

This European Standard establishes the baseline requirements for performing and documenting FAI (First Article Inspection)

for safe use related to mechanical and electrical hazards

Safety of machinery. Evaluation of fault masking serial connection of interlocking devices associated with guards with potential free contacts Ingestion-build-63436 sound signals and interactive services1 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
