• "Linear with Stop" and "Linear with Min."
– "Linear with Stop"
In the input signal range from 20 to 100 %, the setpoint is
influenced linearly.
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. 62.
– "Linear with Min.".
In the input signal range from 20 to 100 %, the setpoint is
influenced linearly.
If the input signal is below 10 %, the pump changes to
operating mode "Min.".
If the input signal is increased above 15 %, the operating
mode is changed back to "Normal".
See fig. 62.

• "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. 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 changes to
operating mode "Min.".
If the input signal is reduced below 85 %, the operating
mode is changed back to "Normal".
