11.7.29 Analog inputs (4.3.8.1 to 4.3.8.7)
Fig. 70 Analog inputs
Description
In the displays 4.3.8.1 to 4.3.8.7, analog inputs can be set.
Each display is divided into three parts:
• Setting of input signal, for instance 4-20 mA
• Measured input value, for instance discharge pressure
• Measuring range of the sensor/signal transmitter, for instance
0-16 bar.
Setting range
It is possible to set the following parameters in each display:
• Not used
• Range of input signal, 0-20 mA, 4-20 mA, 0-10 V
• Measured input value
• Sensor range.
Setting via control panel
1. Mark the Settings menu with .
2. Mark Secondary functions with or , and press .
3. Mark Analog inputs with or , and press .
4. Select the analog input with or , and press .
5. Mark the setting of the analog input with or , and
activate it with .
The activation is indicated by a check mark in the box.

11.7.30 Analog inputs and measured value (4.3.8.1.1 to
4.3.8.7.1)
Fig. 71 Analog inputs and measured value
Description
In the display Analog inputs and measured value (4.3.8.1.1 to
4.3.8.7.1), a function can be related to the individual analog
inputs.
Setting range
It is possible to select one function per analog input. For further
details, see section 12. Measuring parameters.

.
The activation is indicated by a check mark.
6. Mark Measured input value with or , and press .
Now the display 4.3.8.1.1 appears.
7. Select the input with or , and press .
8. Press to return to display 4.3.8.1.
9. Set the minimum sensor value with or , and save with
.

Note
If an analog input is deactivated, the display will
only show the top part, i.e. the setting of the
analog input.
If the input is activated, the middle part,
"Measured input value", will be shown. This
makes it possible to relate a function to the
analog input in another display. When the analog
input has been related to a function, CU 351 will
return to the display for setting of analog inputs.
