I have a dump of my 0T-A (PMC-L) ladder and I'm trying to diagnose why my chuck clamp/unclamp (M51/M52) codes don't actually do anything. When issued, the control just waits indefinitely. No error, just pause, forever. This feature is listed as optional in my manual. I really like to get it working. Obviously if it is in the ladder then I need to sort the hardware to make it work. If it's missing from the ladder then I'd like to add it. Being this is first venture into ladder programming I'm struggling to gather enough information to understand what I'm looking at. Anyone have a PMC-L ladder manual?

I've attached my ladder. Maybe someone more experienced can find it in the ladder? I also attached a scan of the chuck schematic. It's hard to read but it's all I have.

Thanks!
