All the data items ControlModule. Setpoint, StatusModule.
ProcessFeedback, ActualSetpoint and UserSetpoint have a
scaling relative to the feedback sensor. By using the scaling
information of the feedback sensor (FeedbackSensorUnit,
FeedbackSensorMin, FeedbackSensorMax) these data items can
be expressed in absolute units.
Many of the booster system measurement modules require a
particular sensor to be present. As a limited number of sensors
are available, only a few of the measurement modules can be
available simultaneously.
The table below shows the relation between the PROFIBUS/
PROFINET measurement modules and the sensor value selected
on CU 35X.
The table below shows the relation between the Hydro Multi-E
PROFIBUS/PROFINET measurement modules and the
measurement unit selected with Grundfos GO Remote for the
feedback sensor. Only one of the measurement module groups in
the table below is available at a time.
You can calculate, the process feedback scaled according to
ProcessFeedBackUnit from this formula:
Feedback (scaled) = ProcessFeedBack * (FeedBackSensorMax -
FeedBackSensorMin) / 100 % + FeedBackSensorMin
