14.17.1 Setpoint influence
The table below gives an overview of the types of setpoint
influence and the availability depending on pump type.
You can select these functions:
• 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. 61.
Fig. 61 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 above 15 %, the operating mode will be
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 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. 62.
Fig. 62 "Linear with Stop" and "Linear with Min."
• Linear with Min.
The setpoint is influenced inversely from 0 to 100 %.
See fig. 63.
