Via the menu Settings" the signal type (0 – 10 V, 0 – 20 mA, …) is set in this sequence:
Universal Displaytext
1.3 External interfaces
1.3.4 Analog input (AI2)
1.3.4.1 Signal type (AI2)
1.3.4.2 Pressure sensor range (AI1)
1.3.4.3 Pressure sensor type (AI2)
1.3.4.3 /1 Absolute pressure sensor
1.3.4.3 /2 Relative pressure sensor

Setpoint sensor signal types:
• 0 – 10 V : Voltage range of 0 – 10 V for transfer of setpoint values.
• 2 – 10 V : Voltage range of 2 – 10 V for transfer of setpoint values. If the voltage is below 1
V, the motor is switched off and cable break is detected (see Overview of transfer func-
tions).
• 0 – 20 mA : Electric current range of 0 – 20 mA for transfer of setpoints.
• 4 – 20 mA : Electric current range of 2– 20 mA for transfer of setpoints. If the current is be-
low 2 mA, the motor is switched off and cable break is detected (see Overview of transfer
functions).
NOTICE
After selecting one of the external sources, the setpoint is paired to this
external source and can no longer be adjusted in the setpoint editor or in
the home screen. This pairing can be cancelled again in the menu “Set-
point source”. The setpoint source must be adjusted again to “Internal
setpoint”. The pairing between external source and setpoint is marked
both in Home screen, and in the setpoint editor in
blue . The status LED
also becomes blue.

Analog Input used as Suction Pressure sensor input:
If the optional function “Lack of water detection via pressure sensor” is activated, the AI 2
can not be configured as setpoint source for the control mode, the option is greyed out.
In this case, the configuration of AI 2 for pressure sensor usage becomes available in the
menu "Settings"
