Fig. 78: Behaviour of analogue input AI2: Setpoint with signal type 2 ... 10 V / 4 ... 20 mA
With an analogue signal between 1 V and 2.8 V or between 2 mA and 5.6 mA, the motor is
switched off.
The cable break detection is active.
An analogue signal smaller than 1 V or 2 mA is detected as a cable break. In this case, a set
substitute setpoint takes effect. The substitute setpoint is set in the menu "Control setting
[" 160] –Setting the setpoint source [" 163]" (see Fig. 73 Control setting with emergency
operation mode).
Depending on the set control mode, the following can be set as substitute setpoint:
• A speed (for control mode "Constant speed n-c")
• A delivery head (for the control modes "Differential pressure Δp-v" and "Differential pres-
sure Δp-c")

Signal type 0 ... 10 V / 0 ... 20 mA:
If an external setpoint sensor is set up at analogue input AI2, the signal type must be set. In
this case 0 ... 10 V or 0 ... 20 mA.
The analogue signal runs between 4 V and 10 V or between 8 mA and 20 mA. The analogue
signal is interpolated linearly. The applied analogue signal of 1 V ... 4 or 2 mA ... 8 mA repres-
ents the setpoint value (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. 79).
Fig. 79: Behaviour of analogue signal AI2: Setpoint for signal type 0 ... 10 V / 0 ... 20 mA
If the analogue signal is less than 1 V or 2 mA, the motor is switched off.
The cable break detection is not active.
