I used to work for a company that builds hydraulic powered rotary transfer machines for machining parts. If the machine is in cycle, an individual unit is in cycle, the drum is indexing, or the machine is sitting idle with the spindles and/or the cutting fluids on, opening a guard door is the same as hitting the e-stop button. With the machine completely idle there is a key switch that must be turned to prevent the hydraulics from shutting off when a door is opened.
Even though opening a door at the wrong time results in all of the parts in the machine being scrapped, this gives a level of safety that should not be compromised.
