I was thinking that the off-board vent plug would reduce the amount of air that would vent at the time of disconnection, but in the example, there is minimal air trapped behind the vent plug vs the tubing between the two vent plugs.

Now, if they required the off-board vent plug to vent to the atmosphere, and the off-board components are connected via a T connector, that would make sense. Close the on-board vent plug, open the off-board vent plug, and then safely disconnect the hosing. But, that is not what is described.

Are we looking at the same picture? Figured 4-16 and 4-17 have the vent valve located on a T, with the other sides going to the compressor and across to the robot. It does vent to atmosphere.
