mA DOSING
This dosing is proportional to the mA current received from the input. The proportionality range and the flowrate can be
freely programmed.
In the menu
Dosing
, select by the cursor "mA" 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:
mA Min
: minimum mA current value
% Min
: flowrate of the pump when the input exceeds mA Min
Dos.Min
: allows to choose if, when the input mA current is less than the minimum mA current, the pump must dose
[act]
at the
% Min
flowrate or it must not dose
[dea]
mA Max
: maximum mA current value
% Max
: flowrate of the pump when the input current is equal to mA Max
Dos.Max
: allows to choose if, when the input mA current is greater than mA Max, the pump must dose
[act]
at the
% Max
flowrate or it must not dose
[dea]
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.
