Trendsetter_400/800_Proofing
This is the roller vacuum level that indicates the vacuum is on, but the roller
is empty. The units are arbitrary (sorry, not in "inches of water"), scaled so
the highest level the vacuum system could generate is about 255 (think bytes).
The level is checked after the vacuum is first turned on, and if it is below
this threshold, an error message pops up and the machine suspends.
Set this parameter to zero to bypass the checking of this threshsold.
