Operating and functions

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:

20 180

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.
