Proportional functioning by 4-20mA current signal
The pump performs a dosing proportional at the current value on its input.
In this functioning mode there are seven parameters to set:
Lower limit L1
Setting from 0 to 20mA at steps of 0,1mA.
Upper limit L2
Setting from 0 to 20mA at steps of 0,1mA.
Capacity L1
Setting from 0 to 100%.
Capacity L2
Setting from 0 to 100%.
Below L1
Setting OFF or ON.
Over L2
Setting OFF or ON.
Example: L1=4mA
L2 = 12mA
Capacity L1 = 10% Capacity L2 = 50%
Below L1= OFF Over L2 = ON
If in input there is a current of 8mA the pump performs a dosing at 30%.
