To calculate exactly the dosing, the following formula can be applied:
Example:
First Prod. Qty = 174 ml
TMax. first P. Qty = 400 ml @ 35°C
First Prod. Freq. = 5 h
First Prod. Hour = N.A.
The system activates P1 pump every 5 hours. If the temperature reached during the latest dosing is 28°C, then the
pump will dose:
4.4 SETTING THE PH (PUMP PH)
The following parameters must be programmed for pH pump operation:
Set Point pH – Work Mode pH – Prop. Band pH
Enter the installer menu, select option Set Point/Timer , press key Enter and then key F more than once, until Set
Point pH is displayed:
Set Point pH
The setpoint indicates the value of pH that is intended to keep.
Press keys ▼▲ to set the desired setpoint and Enter to confirm.
Setpoint values that can be set are 5.0÷9.0 pH.
Work mode pH
The operation mode sets the type of solution it is being dosed: Acid (the pump
starts dosing when the value read by the probe is higher than the Setpoint) or
Alkaline (the pump starts dosing when the value read by the probe is lower than
the Setpoint).
Press keys ▼▲ to select the two options and Enter to confirm.
pH Work mode that can be set is Acid/pH
-
or Alkaline/pH
+
.
Proportional band pH
Represents the value of the band for the proportional dosing in time.
The pump can be active for maximum 300 seconds. If it is activated for less
time, it must be inactive for a time equal to the difference between the set pH
cycle period (refer to par. 5.1) and the activation time.
Press keys ▼▲ to set the desired value and Enter to confirm.
The proportional band can be selected among the following values:
0.5 – 1 – 1.5 – 3 pH.
Time T
ON
of pump activation is calculated with the following formula:
