Default Settings; Rx Probe Calibration; Modification Of The Default Settings - aqua Isipool Rx L3 Manuel D'installation Et D'entretien

Work:
To pass from the stand by state to the work state push one time the Down button and the
display will light up and the Isipool is ready for Rx regulation.

3.3 Default settings:

- mV set point 720 mV
- Alarm window +/- 200 mV

3.4 Rx probe calibration:

Accessories to calibrate the probe:
- Buffer solution 475mV
- Rx probe out of the hose of the plant
A) Clean the electrode and dip it into the 475mV buffer solution, move slowly for 10 seconds
B) Push the CAL button till the display will show the value 475 ,
C) Wait for about 1 minute till the display will show the quality of the electrode (from 25% to
99%). If the value of the quality is under 25% it is suggested to change the electrode.
D) Put the electrode into the hose of the swimming pool plant
E) Push CAL button to switch the pump in working mode.

3.5 Modification of the default settings

Measured mV value (alarm window)
The Isipool Rx has the possibility to control the maximum difference between the mV
value desired and the measure.
This difference can be set by programming: 200mV, 100mV and 50mV.
If the desired value is 720mV and the chosen difference value is 100mV, the "rEr" alarm will
appear:
-if the measure is lower than 620 mV (720-100=620)
-if the measure is higher than 820 mV (720+100=820)
Changing the alarm window:
A) Push the SET button for some seconds (about ten seconds) till the display will show
200 that is the value of the maximum difference between the measure and the desired
value.
B) Release SET button
C) Push one or two times the Down button to decrease the window to 100 or 50mV, push one or
two times the Up button to increase the window to 100 or 200 mV.
D) Push SET button to confirm the choice and to switch in work mode the pump.
Changing the set point:
A) The value of the measured mV in the plant depend on the properties of the water
and of the chemical used for disinfection. At page 9 there is a useful diagram for
chlorine dosage. The value of redox in mV is a function of the pH of the water and the
value of chlorine desired.
B) Push the SET button to read the value of the set point. If you want to change it keep pushing
the SET button and in the same time push the Down button if you want to decrease the value of
the set point or the Up button if you want to increase it. One touch on the button Down or Up
will modify the value of 1 mV.
C) When the value shown by the display will be the desired one, release the button SET.
