8.6.6. Configuring the AO1 current output
The current output gives a 22 mA current when the device shows an operation fault, even if the current
output is disabled.
The 4-20 mA output provides an electrical current, the value of which reflects the flow rate measured by the
device.
Example of relation between the measuring range and the current output:
4
20
20 180
mA
l/min
→ To invert the output signal, give a lower flow rate value to the 20 mA current value than to the 4 mA current
value.
→ To disable the current output, set both range bounds, 4 and 20 mA, to zero. In this case the output delivers a
constant current of 4 mA.
OUtPUt 4 = 28.00AO1
DO1
→ Enter the flow rate associated to a 4 mA current value, in the unit
chosen in the "UNIT" parameter.
→ Confirm.
20 = 6.000
→ Enter the flow rate associated to a 20 mA current value, in the unit
chosen in the "UNIT" parameter.
→ Confirm.
