Analogue inputs can be used for setpoint input or actual value input. The allocation of
setpoint and actual value specifications is freely configurable.
Use the menus "Analogue input AI1 function" ... "Analogue input AI4 function" to set
the type of use (setpoint sensor, differential pressure sensor, external sensor, etc.), the
signal type (0 ... 10 V, 0 ... 20 mA, etc.) and the corresponding signal/value assignments.
In addition, information about the current settings can be queried.
The analogue input is pre-defined for the required signal depending on the selected
control mode of the pump.
