Reverse functioning is when the mA signal increases and pump output proportionally decreases. Select the maximum
mA signal required with mode Set 1 (in relation to the min. output).
E.G. Set 1 maximum signal 20 mA, minimum output.
Set 2 minimum signal 4 mA, maximum output.
WARNING: Reverse functioning can only be selected when mode Set 1 is always higher than the mA signal.
Example n° 1: PUMP MODEL CLASS PROPORTIONAL, 10 L/H, 5 BAR, SIGNAL 4-20 mA
Signal 4 mA: 0 l/h (0% pump flow rate)
Signal 12 mA: 5 l/h (50% pump flow rate)
Signal 20 mA: 10 l/h (100% pump flow rate)
Example n° 2: SAME MODEL, BUT WITH INVERSE SIGNAL: 20 - 4 mA
Segnale 4 mA: 10 l/h (100% pump flow rate)
Segnale 12 mA: 5 l/h (50% pump flow rate)
Segnale 20 mA: 0 l/h (0% pump flow rate)
