Example: Split range operation with two positioners
With "TSUP"
● Auto
● 0 ... 400
The setpoint ramp is effective in "Automatic" mode and limits the
speed of change of the effective setpoint. This parameter is used to
set the value in seconds. When switching over from "Manual" mode
to "Automatic" mode, the setpoint ramp is used to adjust the effective
setpoint to the setpoint of the positioner.
This smooth switching from "Manual" mode to "Automatic" mode
prevents pressure excess in long pipelines.
The parameter "TSUP = Auto" means the slower of the two actuating
times determined during initialization is used for the setpoint ramp.
Parameter value "TSDO" then has no effect.
