The pump proportionally doses at a signal of 20-4(0) mA. On the basis of
the factory settings, the pump interrupts dosage at 20mA and doses at the
maximum set frequency when it receives 4 mA.
For an input signal below the minimum value - 0.2 mA (fixed threshold)
(e.g. 4 - 0.2 = 3.8 mA) the alarm LED lights up to indicate the minimum
value has been exceeded, but the pump continues to dose at the
maximum frequency.
These two values can be modified during programming. The maximum
frequency can be modified during operation, by pressing the
keys at the same time to increase the flow, or the
decrease it.
For an input signal below 0.2 mA, the alarm LED lights up to indicate the
absence of a signal and the pump interrupts dosing.
