Example
See fig. 35.
At a lower sensor value of 0 psi, a set setpoint of 29 psi and an
external setpoint of 60 %, the actual setpoint is 0.60 x (29 - 0) + 0
= 17.4 psi.
Actual setpoint = actual input signal x (setpoint - lower value) +
lower value.
Fig. 35 Example of setpoint influence
Types of setpoint influence
• Not active
• Linear function
• Linear with Stop
• Linear with Min.
• Inverse function
• Inverse with Stop
• Inverse with Min.
• Influence table
• Influence table with Stop at Min.
• Influence table with Stop at Max.
These functions can be selected:
• Not active
When set to "Not active", the setpoint will not be influenced
from any external function.
• Linear function
The setpoint is influenced linearly from 0 to 100 %. See fig. 36.
Fig. 36 Linear function
•"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 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. 37.
– 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 will change to
operating mode "Min.".
If the input signal is increased above 15 %, the operating
mode will be changed back to "Normal".
See fig. 37.
Fig. 37 "Linear with Stop" and "Linear with Min."
• Inverse function
The setpoint is influenced inversely from 0 to 100 %.
See fig. 38.
