If the MV is stored or calculated at the G3ZA and the G3ZA is turned ON
before the EJ1, the controlled variable produced at the G3ZA will be output
(the output may not be 0.0%) until the EJ1 starts operating. When using MV
storage or MV calculation, verify that the controlled variable produced by the
G3ZA is appropriate.
