Ph On-Off Dosing - Astralpool MAXI UP Manual De Regulatión

pH ON-OFF DOSING

Constant dosing that activates when the measure moves away from the desired value.
Set Off. = Value of the measure that causes the STOP of the dosing
Set On = value of the measure that causes the START of the dosing.
% Flowrate =% 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 for Set On a value different from Set Off.
EXAMPLE OF SETTING SET-OFF
The factory settings allow dosing ACID to lower the pH in the plant.
With a measure equal to or greater than 7.30pH the pump doses at 80% of the maximum flow.
With a measure equal to or less than 7.10pH the pump does not dose.
Example:
The measure with stopped dosage from 7.00pH increases up to 7.30pH. At this point the pump waits 3 seconds before
starting to dose. As long as the measure remains above 7.10pH the pump continues to dose at the programmed flowrate
of 80%. When the measure reaches 7.10pH the pump stops dosing.
