• 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".

points)
• 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".

7.14 Predefined setpoints
You can set and activate seven predefined setpoints by
combining the input signals to digital inputs 2, 3 and 4 as shown
in the table below.
Set the digital inputs 2, 3 and 4 to "Predefined setpoints" if all
seven predefined setpoints are to be used. You can also set one
or two of the digital inputs to "Predefined setpoints" but this will
limit the number of predefined setpoints available.
Example
Figure 36 shows how you can use the digital inputs to set up
seven predefined setpoints. Digital input 2 is open and digital
inputs 3 and 4 are closed. If you compare with the table above,
you can see that "Predefined setpoint 6" is activated.
Fig. 36 Principle sketch showing how predefined setpoints
function
If all digital inputs are open, the pump will either stop or run at the
normal setpoint. Set the desired action with Grundfos GO or with
the advanced control panel.
