3.4.3 Step 3: setting up the units
Connect the cables of the temperature sensors or temperature transmitters with the I/O
terminal box. Connect the I/O terminal box with the converter.

of the converter. Then use the
connector

to setup the wanted I/O, as shown in the connection diagrams on the next pages.
3.4.4 Step 4: set up I/O input for energy measurement
Go to menu nr. 2.4.5 via "Measurement
Setup
I/O"
If the recommended KROHNE energy set is used, only check the installed values of the "Current
inputs". If another energy set is used, teach in the required values. The KROHNE temperature
range is 4 mA = 0

F. Extended range min and max is for an
alarm function. A value lower than the given minimum value and a value higher than the given
maximum will generate a signal that will be logged in the event logger.
