The setpoint to which the pump controls is specified according to "Control settings" section.
The adjustment is made in menu "Control setting" [" 160], "Set setpoint source" [" 163].
"Internal setpoint" must be activated.
The "Cable break detection" function is not active.

The setting of the analogue input AI 2 is only available in the menu if the analogue input
AI2 was previously selected in the menu. To do this, select the following in the menu in
succession:
Universal

1.1.9

Possible signal types when selecting the analogue input as the setpoint input:
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 analogue sig-
nal is interpolated linearly. The applied analogue signal of 5 V or 10 mA represents the set-
point (for instance the speed) at "0 %". The applied analogue signal of 10 V or 20 mA repres-
ents the setpoint of the differential pressure at "100 %". (See diagram Fig. 78).
