IEC publishes corrigendum to IEC 61496-1
The IEC has published Corrigendum 1 to IEC 61496-1 Safety of machinery - Electro-sensitive protective equipment - Part 1: General requirements and tests and Amendment 1 (2007).
This corrigendum adds a new definition for muting ("temporary automatic suspension of a safety function(s) by safety-related parts of the control system") and amends the definitions of OFF-state ("state of the output(s) of the ESPE in which the machine under control is caused to stop running and is prevented from starting (for example, the output circuit is interrupted and disables the flow of current)") and ON-state ("state of the output(s) of the ESPE in which the machine under control is allowed to run (for example, the output circuit is complete and enables the flow of current)").
The full text of the corrigendum is available at www.iec.ch (search the IEC site for "IEC 61496-1 Ed. 2.0 (2008-06)").
