NB: WITH FACTORY
SETTINGS, WHEN IN THE
INPUT THERE IS A
CURRENT OF 4.0mA THE
PUMP DOES NOT DOSE;
WHEN IN THE INPUT
THERE IS A CURRENT OF
20mA THE PUMP DOSES
AT 100% OF THE
FLOWRATE.
PULSES DOSING
For every N pulses received from the water-meter the pump doses the ml of chemical set in mL Dos. The dosing flowrate
is programmed in %Flowrate. The memory function allows to memorize all the impulses coming from the watermeter
while the pump is dosing and to perform the related dosing immediately after.
NB: it is important to define the flowrate of the pump in the Calibration menu.
In the menu Dosing, select by the cursor "Pulses"
and press ENTER.
In the figure on the left you can see the factory
parameters.
Use the ▼▲ buttons to select the parameter to be
changed and press ENTER.
Use the ▼▲ buttons to select the desired value and
press ENTER whenever necessary to confirm the
change.
If you want to esc programming and return to
measurement, press the ESC button for 3 seconds.
PARAMETERS:
N pulses: number of pulses the pump must receive from the water-meter to start the dosing
mL Dos: quantity of product to be dosed
%Flowrate: dosing flowrate
memory: if active [act] allows the pump to memorize the pulses that arrive while it doses and to perform the related
dosing immediately after.
DISPLAY DURING PULSES DOSING:
N are the dosages to be carried out and not the pulses received. Only
if the parameter N pulses = 1 has been programmed, the two things
coincide. On the left the display shows the dosing flowrate in progress
(10%).
ppm DOSING
The pump receives the pulses from the water-meter and automatically calculates the dosing according to the values of
the parameters: ppm, concentration of the chemical product, liters of water passing for each pulse of water-meter and
memory.
NB: it is important to define the flowrate of the pump in the Calibration menu.
