Hello, fairly new to plcs I’m tasked with installing a PE to a micrologix1200, in the attached picture I/14 is the PE I’m installing it’s going to allow accumulation on a flat belt. Right now the belt runs continuously with this PE it will only run when PE is blocked allowing boxes to build. I’m assuming right now the company has a jumper from + to I/14 bypassing this option. Just a couple questions what is the H1 that’s in a box on the diagram? And what is the N1 to the right mean? It’s a 3 wire sensor black (load) brown (+) blue - I haven’t opened the panel yet but I’m assuming the blue and brown run to terminal blocks? Thanks.
