Analog Inputs - Grundfos LCSE Installation And Operating Instructions Manual

7.5 "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
5.2.1 Identification of functional
If you want to set the analog input for a feedback sensor, we
recommend that you do this via the "Assisted pump setup" menu.
See section
7.41 "Assisted pump
If you want to set an analog input for other purposes, you can do
this manually.
You can set the analog inputs via the "Setup, analog input" menu.
See section
7.42 "Setup, analog
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
7.13 "External setpoint
"Other function".
•
Measured parameter
Select one of the parameters listed below, i.e. the parameter to
be measured in the system by the sensor connected to the actual
analog input. See fig. 50.
