12.5.2 Using the analogue input AI2 as
the setpoint input
The setting of the analogue input AI 2 is only available in the menu if the analogue in-
put AI2 was previously selected in the menu. To do this, select the following in the
menu in succession:
Universal Display text
1.0 Settings
1.1 Control settings
1.1.9 Setpoint source
1.1.9 / 2 Analogue input (AI2)
The signal type is set via the menu “Settings”, “External interfaces”, “Analogue in-
put AI2”.

Possible signal types when selecting the analogue input as the setpoint input:
Signal type (AI2)
Fig. 75: Signal types menu (AI2)
Setpoint sensor signal types:
0 ... 10 V: Voltage range from 0 ... 10 V for the transmission of setpoints.
2 ... 10 V: Voltage range from 2 ... 10 V for transmission of setpoints.
0 ... 20 mA: Electric current range from 0 ... 20 mA for the transmission of setpoints.
4 ... 20 mA: electric current range of 4 ... 20 mA for transfer of setpoints.
The analogue input AI2 can only be used as an input for an external setpoint sensor.
Signal type 2 ... 10 V / 4 ... 20 mA:
If an external setpoint sensor is set up at analogue input AI2, the signal type must be
set. In this case 2 ... 10 V or 4 ... 20 mA.
The analogue signal runs between 5 V ... 10 V or between 10 mA ... 20 mA. The ana-
logue signal is interpolated linearly. The applied analogue signal of 5 V or 10 mA repres-
ents the setpoint (for instance the speed) at “0 %”. The applied analogue signal of 10 V
or 20 mA represents the setpoint of the differential pressure at “100 %”. (See diagram
Fig. 76).
