• "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 will change to
operating mode "Stop".
If the input signal is reduced below 85 %, the operating
mode will be changed back to "Normal". See fig.
64 .
– 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 will change to
operating mode "Min.".
If the input signal is reduced below 85 %, the operating
mode will be changed back to "Normal". See fig.
64 .

• Influence table
The setpoint is influenced by a curve made out of two to eight
points. There will be 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 will be a 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 will change to
operating mode "Stop".
If the input signal is increased above 15 %, the operating
mode will be changed back to "Normal". See fig.
66 .

• Influence table with Stop at Max.
The setpoint is influenced by a curve made out of two to eight
points. There will be a straight line between the points and a
horizontal line before the first point and after the last point. If
the input signal is above 90 %, the pump will change to
operating mode "Min.".
If the input signal is reduced below 85 %, the operating mode
will be changed back to "Normal". See fig.
