Purpose of off-board Vent Plug?

That would make sense if there were a way to relieve the pressure. The way the diagrams have it plumbed is the output of the two vent plugs are plumbed together trapping pressurized air between them.

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.

My bad. I didn't look closely enough at the picture. I didn't see the T, and thought it was in-line.

Thanks.

No. My team didn't make it. They are going to Kansas City instead this year.

I applied to be a Ref and RI in KC, but have not heard back. I'm guessing I was too late since we did not know we were going until the end of January.

That's OK, I know people in KC too.
