OPERATIONAL FUNCTIONS OF THE PLUS "PROPORTIONAL" PUMP

In order to facilitate the consultation of this manual, the configuration with the function described is shown in the
subsection titles.

Manual

This configuration is present in all versions. The metering pump operates at a frequency predetermined by the
user within the following range:
•
•
•
During the operational phase of the manual mode, you can view the impulses / minute, the rate of dosage or the
actual litres / hour delivered by the pump; use the left or right arrow keys to select the desired display.

Proportional 1XN (VFT, MF, VFT-T, MF-T)

The pump is provided with a connector for connection to an external water meter which can provide a series of
contacts proportional to the amount of liquid that must be treated. A flashing dot on the display shows the input impulse
from the meter.
For each contact received, the pump delivers a series of injections equal to the N value set by the operator. Any
contacts that come from the meter to the pump, while it is already delivering the N series of injections, are ignored.

Proportional 1XN (M) (VFT, MF, VFT-T, MF-T)

Unlike the previous mode, in this one the pump stores any received impulses in the memory while it is delivering
injections.
Depending on the time interval between impulses coming from the meter, the pump automatically adjusts the
frequency of the injections. If the injections accumulated and still to be dispensed, exceed the value "4 × N", the pump will
go into alarm (if this alarm has been enabled) and stop the metering. The display shows dynamically the number of
injections that must be provided.

Proportional 1:N (VFT, MF, VFT-T, MF-T)

The pump is provided with a connector for connection to an external water meter which can provide a series of
contacts proportional to the amount of liquid that must be treated. Every N contacts received by the meter, the pump
delivers an injection. The display shows the number of contacts received up to the set value. At the delivery of the
impulse the display resets and begins the next count.

Proportional ml x imp (VFT-S, MF, VFT-S-T, MF-T)

The pump is provided with a connector for connection to an external water meter which can provide a series of
contacts proportional to the amount of liquid that must be treated. For each contact, received from the meter, the pump
delivers a number of injections directly proportional to the set value in "ml" (millilitres) requested by the user. The display
shows in a dynamic manner the amount dosed in "ml".

Proportional l x imp (VFT-S, MF, VFT-S-T, MF-T)

As for the previous mode with the difference being that displayed in litres.

Proportional ml x m3 (VFT-S, MF, VFT-S-T, MF-T)

For those who need a ml x m3 metering a specific function has been provided: by setting the required parameters in
the programming menu, the electronic system performs the necessary calculations and determines the type of
intervention required to effect the pump. The parameters that must be defined are the following:
