HC997-999 – MOD. A
Digital multifunction solenoid metering pump
4.4.5 Proportional functioning in 4-20mAcurrent signal
ADSP9000026
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
Below L1= OFF Over L2 = ON
If in input there is a current of 8mA the pump performs a dosing at 30%.
