Case mA Mode:
The pump proportionally doses to a signal of (0)4-20 mA or 20-4(0) mA. Is possible to set the mA input value
corresponding to 0% dosing and the mA input value corresponding to the pump maximum flow rate.
Ex. Direct mA dosing:
mA input for 0% = 5mA
mA input for MAX FLOW RATE = 10mA
Max flow rate = 80%
Ex. Invers mA dosing:
mA input for 0% = 10mA
mA input for MAX FLOW RATE = 5mA
Max flow rate = 80%
The pump proportionally doses at a signal of 0/4-20 mA. On
the basis of the factory settings, the pump interrupts
dosage at 0mA and doses at the maximum set frequency
when it receives 20 mA. These two values can be modified
during programming. The maximum and the minimum
frequency can be modified during operation, by pressing
the
keys at the same time to increase the flow,
or the
keys to decrease it.
