Case PPM Mode:
In order to maintain the selected ppm of chemical, The pump calculates the right dosing rate starting from the
following parameters:
Pulse per minute on pulse input
•
Flowmeter factor (pulse/liter)
•
Density of chemical
•
Concentration of chemical
•
If calculated flow rate is bigger than maximum, the pump goes in MEM function (if selected) and doses the lasting
quantity when possible.

Case 1:N Mode:
Pump doses following pulses number to the related input.
One input pulse generate 1 second of dosing at set speed (N)
e.g.
If N is set to 1 (N=1), pump doses for one second at speed=1% of Max speed
•
If N is set to 100 (N=100), pump doses for one second at speed=100% (Max speed)

The pump doses in proportion to an external signal (i.e.:
impulse launch counter), automatically calculating the
relationship between incoming signals and pump speed on
the basis of the programmed ppm value.
