10.9 Sensor-based Modbus registers
The tables below show the relation between the sensor-related Modbus registers and the sensor setup for the individual booster systems.
The table below shows the relationship between the
measurement modules for the Hydro Multi-E model G Modbus
and the measurement unit selected with Grundfos GO Remote for
the feedback sensor. Only one of the measurement module
groups in the table below will be available at a time.
The process feedback scaled according to ProcessFeedBackUnit
can be calculated from this formula:
Feedback (scaled) = ProcessFeedBack × (FeedBackSensorMax -
FeedBackSensorMin) / 100 % + FeedBackSensorMin
