The features above are applicable only to Machine Configuration 3 in
injection, pack and hold, and plasticate profiles, and work only on the
pressure loop mode. A zero value in any of these locations defaults to one.
For example, if the injection pressure loop calculates an output value of
32000, but V228 = 10, then the actual output is 32000/10 = 3200 or 1 volt.
