Proportional By A 4-20Ma Current Signal - Aqua HC 997 Manual De Instrucciones

HC997 – MOD. B
Digital multifunction solenoid metering pump
4.4.5 Proportional functioning by 4-20mA current signal
ADSP9000030
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%.
