Presence Sensing Device Initiation: How One Operation Function Can Enhance Productivity, Cut Costs & Improve Safety
Presence Sensing Device Initiation (PSDI) refers to the use of a Presence-Sensing Device (often, though not limited to, light curtains) both to perform the safeguarding function and to initiate the machine cycle. While this is not new technology, having been around for nearly half a century, PSDI has frequently been misunderstood, especially regarding when and where it is permissible to use PSDI in compliance with current safety standards and regulations. For example, many standards (including ANSI B11.1 for mechanical power presses) explain how to implement PSDI correctly, while OSHA prohibits the function on mechanical power presses in the US and US territories. This white paper clarifies what PSDI is, how it works, where it can and cannot be used, and the ways in which PSDI can not only ensure safety but also significantly increase productivity and throughput.
