DOSING MODE SETTINGS
A switch (shown in the figure) that regulates the dosing mode of the pump
is present in the part relative to the electrical connections on the circuit.
The two different modes are:
Constant (switch in position C)
The pump constantly dispenses the percentage selected with a
potentiometer.
Proportional (switch in position P)
The pump doses proportionally to the input signal (Pulse emission meter).
DOSING FREQUENCY SETTINGS
1 2 3 4 5 6
With the switch in position C, it’s possible to set, through a jumper in the
pulses input (shown in the figure), two different frequency settings with the
regulation potentiometer at 100%:
100% without the jumper in the pulses input
The pump doses at a maximum frequency of 160 strokes/minute.
20%
with the jumper in the pulses input
The pump doses at a maximum frequency of 32 strokes/minute
