I recently purchased a VMC from a machine builder in China. Overall the machine is great. One problem tho is that they didn't install any door interlocks. Looking through the commissioning manual, I'm seeing support for it on the digital I/O OUT, on the X200 connector - Pin 8. What I'm unsure of however, is how to wire this up. I figure I can either put a NO/NC roller contact switch on it, or better still an inductive sensor, but first I need to figure out how to wire ANYTHING up to the controller. I talked with the builder, and they acknowledged that they don't install door safety interlocks normally, and because I hadn't requested it, they didn't install them. Big deal. I figure I can retrofit some on the machine... if I can only figure out where and how to wire it up!
Anybody have any experience with wiring on the 808D (or 802D, 820D, or 840D) controller that could walk me through what needs to be connected from where to where to make this happen?
It LOOKS like I just need to come out of X200, pin 8, go to a NO switch, and then connect the closed part to ground back on pin 10 of the x200 - M - External Ground point.
Here's the commissioning manual, in particular, page 44:

I'm a bit... pensive... to go mucking about with the wiring on my new machine... but I have GOT to get safety door interlocks enabled if I have ANY chance of my insurance company not hanging me out to dry in the event of an accident, door safety interlock related or not.
