Re: Off robot air compressor

Not beat a dead horse but I want to see if others agree with me.

Wouldn't it be simpler to require the pressure relief valve (PSV) be mounted to the accumulator (ACC) or the vent valve (HV). This would make it very clear that the system was at a safe pressure and would eliminate the need to have many of these systems on the robot.

I have been a proponent of this for several safety reasons but it should also simplify inspection and allow for any charging source. If you over charge the ACC you will actually be at the lower reseating value of the PSV. Also having only the HV to vent does not adequetly prevent several potential over pressure issues particularly when a robot is shipped pressurized and exposed to extreme temperatures (in excess of 150F).

I have all season since reading the pnuematic rules related to an off board compressor been extremely disappointed with the wording. I would like to see FIRST take some of these items into account when writing next years rules.
