• "Inverse with Stop" and "Inverse with Min.".
– "Inverse with Stop"
In the input signal range from 0 to 80 %, the setpoint is
influenced inversely.
If the input signal is above 90 %, the pump changes to
operating mode "Stop".
If the input signal is reduced below 85 %, the operating
mode is changed back to "Normal".
See fig. 61.
– "Inverse with Min.".
In the input signal range from 0 to 80 %, the setpoint is
influenced inversely.
If the input signal is above 90 %, the pump changes to
operating mode "Min.".
If the input signal is reduced below 85 %, the operating
mode is changed back to "Normal".
See fig. 61.

• "Influence table".
The setpoint is influenced by a curve made out of two to eight
points. There is a straight line between the points and a
horizontal line before the first point and after the last point.

• "Influence table with Stop at Min.".
The setpoint is influenced by a curve made out of two to eight
points. There is straight line between the points and a
horizontal line before the first point and after the last point. If
the input signal is below 10 %, the pump changes to operating
mode "Stop". If the input signal is increased above 15 %, the
operating mode is changed back to "Normal". See fig. 63.
