Grundfos CIU 501 User Manual

9.8 Sensor-dependent measurements
Many of the measurement registers require a particular sensor to be present.
Because a limited number of sensors are available, only a few of the "S" marked data modules are available simultaneously.
The following sections describe the relation between available Modbus measurement registers and the setup of sensors. The description is
split into sections for different pump types, because the approach varies.
Old MAGNA and UPE pump types
• No connection of external sensor possible.
MAGNA3
• Connection of temperature sensor and selection of analog input function "Constant temperature control" will make RemoteTemp2 (00337)
measurement available.
• Connection of pressure sensor and selection of analog input function "Constant pressure control" will make RemotePressure1 (00316)
measurement available.
