Pepperl+Fuchs Podcasts

Pepperl+Fuchs’ TechTalk helps listeners gain an insight into modern automation technologies by focusing on AS-Interface (Actuator Sensor Interface) and its associated safety technology, Safety at Work. TechTalk covers topics that range from hardware selection to installation and maintenance. Control engineers familiar with AS-Interface will get the latest news on specification enhancements, hear about new products, and familiarize themselves with established and cutting-edge troubleshooting methods, tips, and tricks.  Users who are interested in applying these technologies will learn what it takes to set up an AS-Interface system, how Safety at Work improves safety systems, and why those technologies have the potential to save time and money during all phases of a project.

Muting is a very powerful function and an integral part of several AS-Interface safety controllers.  But what if muting does not work right?  Look at the mounting and don't make the timing parameters too restrictive. 

  • -- When setting up muting sensors, it is important to place them such that the muting function can be started up before the box interrupts the safety light curtain.
  • -- When setting up muting for the first time, start with infinite muting.  It is always possible to change that later.  Similarly, don't use a "tolerance interrupt time" that is too long as it delays activation of the muting function.
