– 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. 39.
– 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".
