-The unit will measure Ph and Rx (redox) for 40 seconds. This measurement will be stored
in memory.
If PH is set to -:
If the Ph value is much higher than the setpoint (target value), the Ph dosing pump runs for
2 min.
If the Ph value is lower than the setpoint (target value), the dosing pump does not run.
If the Rx value is lower than the setpoint, the electrolysis cell produces 4 min of chlorine.
After 6 minutes salt electrolysis and pH dosing will stop, and pH and Redox will be
measured again. The above cycle repeats.
11.3) PH + or PH-
Press the lower key. The setting "PH+ or PH-" is now checked. Press
the center key to activate this setting. A - sign appears. Press the
center key again. You have now set the supply of PH-.
PH- must always be set when using liquid chlorine. Liquid chlorine
already contains PH+. It is always added as a stabilizer.
PH- must always be set when using salt electrolysis. When chlorine is
produced by the salt electrolysis unit, PH+ (NaOH) is formed as a by-product.
It is not possible to add both PH+ and PH: PH or PH+, never both at the same time.
11.4) PH SP (Set Point)
Press the lower key. The setting "PH SP" is now checked. Press the center key to
activate this setting. You will now see the preset value. Now you can set the
value higher or lower with the upper or lower key after which you confirm by
pressing the middle key. The value is now set according to your needs.
As a rule, the pH will be controlled at 7.4
As a rule, the pH will be regulated at 7.4
11.5) Rx SP (Redox Setpoint)
The redox is a measure of the chlorine content.
At start-up we recommend setting the setpoint to 700mV, in the same way as
described above for pH. After the first start-up measure the chlorine content with
a colour method. If necessary, adjust the setpoint for redox (decrease if chlorine is
too high, increase if chlorine is too low).
