1.3.3 Analogue input (AI1)
1.3.3.1 Signal type
Possible signal types when selecting the analogue input as actual value input:
Actual value sensor signal types:
0 ... 10 V: Voltage range from 0 ... 10 V for the transmission of measured values.
2 ... 10 V: voltage range of 2 ... 10 V for the transfer of measurement values. A cable
break is detected at a voltage below 1 V.
0 ... 20 mA: Electric current range from 0 ... 20 mA for the transmission of measured
values.
4 ... 20 mA: electric current range of 4 ... 20 mA for transfer of measured values. A cable
break is detected if the electric current is less than 2 mA.
For the transfer of analogue signal values to actual values, only the transfer ramp is now
defined. The transmission characteristics are fixed and are as follows:
Signal type 2 ... 10 V / 4 ... 20 mA
Factory setting:
The analogue input AI1 is factory-set with the differential pressure sensor (with variant
R1: not assigned) and set to signal type 2 ... 10 V.
"Pump flange" is set as the pressure sensor position.
The pressure value set in the factory as the pressure sensor range (see Fig. 67 Analogue
input AI1 menu and Fig. 69 Pressure sensor range AI1) corresponds to the maximum
sensor range of the connected differential pressure sensor.
The pressure sensor range varies depending on the pump type.
The sensor range is documented on the rating plate of the differential pressure sensor.

The actual value of the differential pressure runs linearly between the analogue signals
2 V and 10 V. This corresponds to 0 % ... 100 % of the sensor measuring range. (See
diagram Fig. 70).
