Once the configuration is set, scrolling the menu with the RIGHT () and LEFT () arrow keys, confirm the choice with
the START / STOP button. For an eventual reconfiguration it is necessary to do a TOTAL RESET.
Injection Calibration Procedure
For accurate metering, in the eOne and MF Plus models we have implemented the option to automatically or manually
set the actual flow rate for each injection. The following describes the practices that must be observed for "AUTOMATIC"
calibration:
OPERATIONAL FUNCTIONS OF THE MULTIFUNCTION 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
Fill a graduated cylinder with the additive to be dosed by the pump and immerse the suction tube in it.
•
Connect the delivery pipe of the metering pump to the plant to be treated.
•
From the "SETTINGS" menu select the function "FLOW CAPACITY" and select the "AUTOMATIC" mode.
•
Press the DOWN ARROW button to proceed to the priming of the metering pump which will begin to emit
•
injections, until the pump body and the two suction and discharge pipes are full.
Once finished priming press the DOWN ARROW button.
•
Select the frequency of calibration procedure by press RIGHT AND LEFT ARROW buttons (standard value is
•
150 imp/min.).
Press DOWN ARROW button. The pump will run for one minute.
•
Once the injections are finished the metering pump will have suctioned a certain amount of additive whose
•
quantity can be calculated by means of the scale on the cylinder.
The amount of suctioned fluid, for example: 110 ml, should be set on the display and via the ARROW DOWN
•
button the selected value will be confirmed.
The logic of the pump will run the following operation:
•
value of additive suctioned / number of impulses delivered = flow rate of each injection
(110 / 150 = 0.73)
the factory-set value of 0.45 ml will become 0.73 ml.
•
0 to 300 impulses / minute (depending on the maximum flow)
0 to 900 impulses / hour
0 to 900 impulses / day
