I have recently reviewed an old machine we have had in our plant for some time. I had assumed that the capacitive palm buttons contained some
anti-tie down circuitry. When they failed and I replaced them I started a risk analysis to ensure I had proper safeguarding. The PLC controlling the machine has something like anti-tie down logic for the button operation but I am unsure as to the proper control to install and have not found any conclusive design direction. Can anyone relate some of their experiences or direct me to better information?
