11.5 Application and function of the analog inputs AI1 and AI2
Analog inputs can be used for setpoint input or actual value input. The allocation of setpoint and actual value
specifications are freely configurable.
Use the menus "Analog input AI1 function" and "Analog input AI2 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 analog input is pre-defined for the required signal depending on the selected control mode of the pump.
