8.7.31 Analog inputs (4.3.8.1 - 4.3.8.7)
Fig. 79 Analog inputs
Description
In the menu, you can set "Analog inputs". Each display is divided
into three parts:
• Setting of input signal, for instance 4-20 mA
• "Measured input value", for instance "Outlet pressure"
• Measuring range of the sensor/signal transmitter, for instance
0-16 bar.
Setting range
You can 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 the operating panel
• Settings > Secondary functions > Stop function > Go to setting
of analog input.
Factory setting
8.7.32 Analog inputs and measured value (4.3.8.1.1 -
4.3.8.7.1)
Fig. 80 Analog inputs and measured value
Description
A function can be related to the individual analog inputs.
Setting range
You can select one function per analog input. For further details,
see the installation and operating instructions for Control MPC.

Setting via the operating panel
• Settings > Secondary functions > Go to setting of analog input.
1. Select analog input.
2. Select: Measured input value. Display 4.3.8.1.1 appears.
3. Select input.
4. Press [Back].
5. Set the minimum and maximum sensor value.
If an analog input is deactivated, the display only
shows the top part, that is the setting of the analog
input.
If the input is activated, the middle part, "Measured
input value", is 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 352 will return to the display for setting
of analog inputs.

If more flow rates are used, the flow rate measured
and shown is the sum of defined flow rates.
