This control mode requires either a factory-fitted or external
differential-pressure sensor or two external pressure sensors as
shown in the examples below:
Fig. 37
Constant differential pressure
8.1.5 Constant curve
The pump can be set to operate according to a constant curve,
like an uncontrolled pump. See fig. 38.
The desired speed can be set in % of maximum speed in the
range from 25 to 100 % (110 %).

Analog inputs
Available inputs depending on the functional module fitted in the
pump:
To set up an analog input, make the settings below.
Function
The analog inputs can be set to these functions:
•
Not active
•
Feedback sensor
•
Ext. setpoint infl.
See section
•
Other function
.
Measured parameter
Select one of the parameters, i.e. the parameter to be measured
in the system by the sensor connected to the actual analog input.
Unit
Available measuring units:
Electrical signal
Select signal type (0.5 - 3.5 V, 0-5 V, 0-10 V, 0-20 mA or 4-20
mA).
Sensor range, min. value
