Azbil Corporation Using the display panelModel MGG10C/14C - MagneW FLEX+/PLUS+ Converter 4-33Normal/reverse automatic switching rangeAutomatically switches the range when the fluid flow direction reverses.Hysteresis setting is available when normal/reverse switching is selected.Analog outputNormal direction: 4 to 20 mA DCReverse direction: 4 to 20 mA DCWhen there is a pulse outputThere is no distinction in output between the normal and reverse directions. Thepulse weight is also the same.The built-in counter simply integrates the flow rate without distinguishingnormal and reverse directions. However, when normal/reverse differential flowintegration is selected, integration of the “-” direction (subtraction) is available.Example: In the normal direction-100 g -99 g -98 g... 0 g 1, 2, 3In the reverse direction100 g 99 g 98... 0 g -1, -2, -3With indicationWith a reverse flow rate, the “-” symbol will appear on the flow rate display.With built-in counter, it is possible to select the normal/reverse differential flowintegration function.Contact outputNormal/reverse distinction status signalThe contact output status at shipment is as follows.Range No.1: ClosedRange No.2: OpenReverse setting is also possibleOutputd.c. a.b.Input-100% 100%0%20 mA4 mAeFigure 4-3 Normal/reverse automatic switching range(Example of setting)j AUTO range• Range No.1 (normal range): Outputs 4 to 20 mA for 0 to 30 m3/h (a-b).• Range No.2 (reverse range): Outputs 4 to 20 mA for 0 to -10 m3 /h (a-d).k WIDE range• Outputs 4 to 8 mA for -10 to 0m 3 /h (c-e), 8 to 20 mA for 0 to 30m3 /h (e-b).When WIDE is selected, Low-flow-cut is not performed.
