9.SPRE - Split range end
With these two parameters in combination with parameter "7.SDIR", you can limit the
effective setpoint. This allows split range tasks with the following characteristic curves to be
solved:
● rising/falling
● falling/rising
● falling/falling
● rising/rising

The factory setting is "100".
10.4.2.4 Description of parameters 10 and 11
10.TSUP - Setpoint ramp OPEN
and
11.TSDO - Setpoint ramp CLOSED
The setpoint ramp is effective in automatic mode and limits the speed of change of the
effective setpoint. When switching from manual to automatic mode, the setpoint ramp is
used to adjust the effective setpoint to the setpoint occupied by the positioner.
