Description Of Functions For Pumps; Analog Inputs - Grundfos Hydro Multi-E Series Installation And Operating Instructions Manual

13. Description of functions for pumps

13.1 Analog inputs

Available inputs depend on the functional module fitted in the
pump:
Function (terminal)
Analog input 1, setup (4)
Analog input 2, setup (7)
Analog input 3, setup (14)
* See section 8. Identification of functional
If you want to set an analog input for other purposes, you can do
this manually.
If you make the manual setting via Grundfos GO, you need to
enter the menu for the analog input under the "Settings" menu.
Function
The analog inputs can be set to these functions:
• "Not active"
• "Feedback sensor"
The sensor is used for the selected control mode.
• "Ext. setpoint infl."
See section 13.7 External setpoint
• "Other function".
Measured parameter
Select one of the parameters listed below, meaning the
parameter to be measured in the system by the sensor connected
to the actual analog input. See fig. 45.
