13.6 "Proportional-pressure setup"
"Control-curve function"
You can set the curve either to quadratic or linear.
"Zero-flow head"
You can set this value in % of the setpoint. With a
setting of 100 %, the control mode is equal to
constant differential pressure.
13.7 Analog inputs
* See section 7.5.1 Connection terminals,
advanced functional module, FM 300.
Set the analog input for a feedback sensor via the
Assisted pump setup menu. See section
13.41 Assisted pump setup.
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 13.42 Setup, analog input.
If you perform the manual setting via Grundfos GO,
you need to enter the menu for the analog input
under the Settings menu.
Function
You can set the analog inputs to these functions:
•Not active.
• Feedback sensor.
• Ext. setpoint infl..
See section 13.16.1 Setpoint influence.
• Other function.
Measured parameter
Select one of the parameters, such as the parameter
to be measured in the system by the sensor
connected to the actual analog input. See fig. 39.
