You've got a fancy machine, if you have the air powered enclosure!

The door should be controlled via another solenoid.
And having just had a quick look through the wiring diagrams, there should be GOS (Guard Open Solenoid) and GCS (Guard Close Solenoid), controlled by a GOR and GCR relays.

I'm wondering if your machine has also had the pneumatic vice option fitted, as a quick look at a manual shows it should have it's own regulator below the main input regulator.
Is there a VOS (Vice Open Solenoid) , and corresponding VOR relay fitted?

I'm guessing there are additional M-codes to control those, but I've got no idea what they'll be, although there may be additional configuration options that need set before you get the functionality.
