Note 1: The engineering units set with the Engineering parameters, SCH1, SCL1, and SCDP1.
Note 2: MV (Manipulated output variable) can be set only with the MV operation key at the bottom of the front panel. MV will be displayed when the controller mode is set to cascade or selector.
Note 3: ATSTUP can not be set if the controller mode is set to the selector or the selector control module is being used in the programmable mode.
