MENU DOSING
The DOSING menu allows you to choose the type of pump dosing:
Manual, mA, Pulses, ppm, Quantity, Timer Dos, Timer
NB: to change the type of dosing, confirm with the ENTER button at least one parameter of the new dosing
mode.
Press the ENTER/MENU button for 3 seconds to enter
programming.
Select by the cursor the menu Dosing and press ENTER.
Position the cursor on the type of dosage to choose and press
ENTER to enter to the submenu and proceed with the
modification.
If you want to esc programming and return to measurement,
press the ESC button for 3 seconds.
-Manual, the pump doses constantly at the programmed flowrate. It is possible to activate a cyclic dosage with
programmable time of delay, time of dosing (Ton) and time of not dosing (Toff).
-mA, flowrate proportional to the mA current received from the input. Fully programmable range of proportionality.
-Pulses, flowrate proportional to the pulses received from a water-meter. It is possible to memorize the pulses during the
dosing
-ppm, flowrate automatically adjusted to reach the desired ppm level (water-meter signal)
-Quantity, dosing of a programmable quantity at each switching on of the pump or at the receiving of the enable signal
(optional)
-Timer dos, dosing at an hourly rate. If the enable option is active, the pump will dose hourly during the reception of the
enable signal (ex: flocculant, oxygen, sanitizing dosage).
-Timer, 10 programmable doses, daily and weekly.
MANUAL DOSING
There are 2 manual dosage types:
1) With the Cycle parameter deactive (Cycle [dea]) the dosage is constant at the defined flowrate (% Flowrate)
2) With the Cycle parameter active (Cycle [act]) the dosage is constant at the defined flowrate (% Flowrate) but is
also cyclical with programmable ON (Ton) and OFF (Toff) times. Furthermore, the dosing can be activated after a
programmable delay (Td) when the pump is switched on or when the enable signal is received. The enable input
is optional and therefore may not be present. See the Connections diagram on page 21. NB: if the optional enable
is present, you can choose whether to activate it or not in the SET UP menu; page 23.
In the menu Dosing, select by the cursor "Manual" and
press ENTER.
Use the ▼▲ buttons to select the parameter to be
changed and press ENTER.
In the figure on the left you can see the factory
parameters with cycle disabled and with active cycle.
Td:this is the time in seconds (from 0-9999sec) that the
pump waits before dosing the chemical after its
switching on or after receiving the enable signal.
Ton:this is the time in seconds (from 0-9999sec) of
dosing
Toff: this is the time in seconds (from 0-9999sec) of
stop dosing.
