E-stop...we don't need no stinkin' e-stops!
Let's assume that the risk assessment is complete. As long as the re-positioning of the device does not endanger a worker - out of reach etc - do whatever ya like. I worked in wired cells that were designed with master and zone e-stops to allow total or partial line shutdowns. Example: two parallel conveyors merge to feed one main. One conveyor can be safely shutdown for proactive maintenance (I'm told it DOES happen somewhere) while the main line is fed from the other. Adding a "master" e-stop - wired upstream of the cell e-stops - would not diminish the existing safety of your cell. If a risk assessment doesn't mandate it no big deal. A risk assessment is the minimum requirement.
