The following example applies to a pump in an application where
a pressure sensor gives a feedback to the pump. If the sensor is
retrofitted to the pump, you must set it up manually as the pump
does not automatically register a connected sensor. See section
7.5 Analog inputs
.
Figure 2 shows that the light fields 5 and 6 are activated,
indicating a desired setpoint of 3 bar with a sensor measuring
range from 0 to 6 bar. The setting range is equal to the sensor
measuring range.
