Characteristics of the analogue output according to the standard IEC 60947-5-7
1: Output current
2:
Volumetric flow quantity
3: Temperature
4: Display range
5: Measuring range
6: Range between analogue start point and analogue end point
7: The unit is in the error state (FOU = OFF)�
8: The process value transmitted in an analogue way is therefore below the display
range�
9: Curve of the analogue signal at factory setting
10: Curve of the analogue signal with shifted ASP and AEP
11: The process value transmitted in an analogue way is therefore above the display
range�
12: The unit is in the error state (FOU = ON)�
ASP = analogue start point: determines at which measured value the output signal is 4 mA
AEP = analogue end point: determines at which measured value the output signal is 20 mA
VMR = final value of the measuring range
= 100 %
Minimum distance between ASP and AEP = 20 % of the measuring range
In the set scaling range the output signal is between 4 and 20 mA�
