Azbil MagneW FLEX+/PLUS+ MGG10C - Normal;Reverse Automatic Switching Range; Figure 4-3 Normal;Reverse Automatic Switching Range

Azbil Corporation Using the display panel
Model MGG10C/14C - MagneW FLEX+/PLUS+ Converter 4-33
Normal/reverse automatic switching range
Automatically switches the range when the uid ow direction reverses.
Hysteresis setting is available when normal/reverse switching is selected.
Analog output
Normal direction: 4 to 20 mA DC
Reverse direction: 4 to 20 mA DC
When there is a pulse output
There is no distinction in output between the normal and reverse directions. The
pulse weight is also the same.
The built-in counter simply integrates the ow rate without distinguishing
normal and reverse directions. However, when normal/reverse dierential ow
integration is selected, integration of the “-” direction (subtraction) is available.
Example: In the normal direction
-100 g -99 g -98 g... 0 g 1, 2, 3
In the reverse direction
100 g 99 g 98... 0 g -1, -2, -3
With indication
With a reverse ow rate, the “-” symbol will appear on the ow rate display.
With built-in counter, it is possible to select the normal/reverse dierential ow
integration function.
