9.7 Sensor-dependent measurements
As appears from the table, 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 will be available simultaneously.
The sections following 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.
CUE and all E-pump types except models H and I
* CUE and 11-22 kW E-pumps only.
** CUE, 11-22 kW E-pumps and model G only.
