Setting data
• This setting is normally used at the default value.
• This sets the advanced PID constant
α.
• This setting is used to have the local SP track the PV when in
manual mode.
• The setting prevents abrupt changes in the MV when switching from
manual mode to auto mode.
If an input error occurs during PV tracking, the local SP will change to
the upper limit of the sensor setting range.
