DO 3 Deviation
The settings of this parameter are only effective in the Pressure control
mode.
«DO 3 Deviation» is a control output. Its settings do not directly affect the pressure control
process or the gas flow adjustment. They only define the conditions under which a
superordinated control system considers the valve to be "in position".

This parameter is set automatically to 10% of the F.S. (full scale) when an
