ON-OFF DOSING
Constant dosing that activates when the measure moves away from the desired value.
Set Of
f. = Value of the measure that causes the STOP of the dosing
Set On
= value of the measure that causes the START of the dosing.
% Flowr
ate =% constant dosing flow rate
Del.On
= seconds expected before dosing when measure exceeds the Set On value.
The hysteresis between Set Off and Set On allows the measure to reach a value halfway between the two values
.
ATTENTION: choose Set Off for a value different from Set Off.
EXAMPLE OF SETTING Set Off.:
In the
Dosing
menu, select "
ON-OFF
" by the cursor
and press
ENTER
.
The factory parameters are shown in the figure on the
left.
Use the ▼ ▲buttons to move the cursor and select
the parameter to be modified and press
ENTER
to
enter the modification.
Use the ▼ ▲ keys to select the desired value and
press the
ENTER
button each time to confirm the
change.
If you want to esc programming and return to
measurement, press
ESC
for 3 seconds.
The factory settings allow to dose Chlorine in the plant.
With a measure equal to or greater than 730mV the pump does not dose.
With a measure equal to or less than 710mV the pump doses at 80% of the maximum flow.
Example:
The measure with stopped dosage drops to 710mV. At this point the pump waits 3 seconds before starting to dose. As
long as the measure remains below 730mV the pump continues to dose at the programmed flowrate of 80%. When the
measure reaches 730mV the pump stops dosing.
