CONSTANT MODE (switch in position C)
The pump dispenses the percentage selected manually with a potentiometer.
Steady green LED switches off with every stroke that the pump runs.
Flashing Green led with the potentiometer to 0.
PROPORTIONAL MODE 1:N (switch in position P)
For every external pulse received (water-meter pulse sender), the pump makes “n” strokes, as regulation scale of
the potentiometer (1=10% - 10=100%). At the first signal received, the pump makes “n” strokes at maximum speed,
and then automatically distributes the “n” strokes, measuring the time between two successive pulses, for a
maximum of 60 seconds, after which period the pump once again doses at maximum speed, resetting the time
count. The pump also has a memory alarm, which is triggered if it receives other external signals (water-meter
pulse sender) during the dosage of the “n” strokes.
Below are some examples of operation:
