10.7.20 Overview of analog inputs (4.3.8)
Fig. 47
Overview of analog inputs
Description
In this menu the analog inputs of the Hydro MPC can be set.
Each input can be activated and related to a certain function.
As standard, the Hydro MPC has three analog inputs. If the
Hydro MPC incorporates an IO 351B module (option), the number
of analog inputs is 5.
In the display, all analog inputs are shown so that their physical
position in the Hydro MPC can be identified.

10.7.21 Setting of analog inputs (4.3.8.1 to 4.3.8.7)
Fig. 48
Setting of 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:
• Input deactivated
• Range of input signal, 0-10 V, 0-20 mA, 4-20 mA
• 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 acti-
vate it with .
The activation is indicated by a check mark in the box.
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. The displays in
10.7.22 show an
example.
When the analog input has been related to a function, CU 351 will
return to the display for setting of analog inputs.
