Analogue inputs can be used for setpoint input or actual value input. The allocation of set-
point and actual value specifications is freely configurable.
Settings 0-10 V, 4-
20 mA, PT1000, Ext. OFF,
Ext. MIN....
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.
In the "Settings" menu
1. "External interfaces"
2. "Function analogue input AI1" ... "Function analogue input AI2".
Set the used signal type
and the associated
parameters for the
analogue input
.
Example: setting an external setpoint sensor for Δp-v
After selecting one of the options "Analogue input (AI1) function" ... "Analogue input (AI4)
function", select the following query or setting:

NOTICE
The differential pressure sensor of the Stratos GIGA2.0-I/-D is pre-con-
figured to 2 ... 10 V at the factory.
For the Stratos GIGA2.0-I/-D ... R1, no analogue input is configured at the
factory.
