If you have a pressure maintaining valve set for 2000 psi the pressure will rise to 2000 and then stop rising as the PMV allows flow into the empty 100 ci tank. It may remain at 2000 for some time (or it may drop some) until the 100 ci tank passes 2000, and then the compressor output pressure will rise. This could appear to be a stoppage. The real pressure in the 100 ci tank should be visible on the 100 ci tank gauge. Could this be happening?
