13.1 Setpoint setting

Set the desired setpoint of the pump by pressing
The light fields on the control panel will indicate the setpoint set.
13.1.1 Pump in differential-pressure control mode
The following example applies to a pump in an application where
a pressure sensor gives a feedback to the pump. If you retrofit the
sensor to the pump, set it up manually as the pump does not
automatically register a connected sensor.
Figure 26 shows that the light fields 5 and 6 are activated,
indicating a desired setpoint of 4.3 psi (3 m) with a sensor
measuring range from 0 to 8.5 psi (0 to 6 m). The setting range is
equal to the sensor measuring range.
