pH CONTROL
CALIBRATE PROBE: In order to control the pH we have to calibrate the probe, only by this
way we will give a correct reading of the swimming pool pH water.
1 - First you have to clean the tube with water, careful not to hit or damage the tip. Then dry
thoroughly with a dry cloth carefully.
We introduce the probe into the buffer solution and follow the menu
2 - pH REFERENCE 1 . In this section we indicate the value of the buffer solution we have
introduced in the probe.
3 - SAMPLING . Calibrate the probe. The display will indicate if the probe is correct, if so
proceed to the next step. If we mark the display error, repeat from step 1 for sure. If you
still make errors, the probe is damaged.
4 - We clean the probe well with water to remove all traces of the buffer solution and dried
while the probe. Then dive into the second buffer.
5 - REFERENCE pH 2 . Indicate the value of the buffer have been introduced into the tube
6 - SAMPLING . Calibrate the probe. The display indicates whether the probe is correct or
not.
SET pH: In this section we set the pH values we want for our pool and how much will be
corrected.
1 - pH MAX. Indicate the maximum pH value that we want in the pool. When water pH
exceeds the set value, the system will start automatically to pH minimum.
2 - pH MINIMUM. Indicate the minimum pH value we want for our pool. When the system is
able to decrease the pH to this value, it stops automatically.
3 – PUMP RUN TIME. Indicate the time in which we operate dosing pump (in seconds).
4 - PUMP STOP TIME. Is a security system for pumping not to much acid in the pool
because it might be a period of time since the acid is pumped, it passes through the
installation, reaches the pool, is mixed with water and passes through the reading of the
pH probe. That period of time could reduce the pH value less than desired. In this way we
can combine the pump seconds with the stop seconds.
Keep in mind that whenever you give MAMNET voltage with pH, it takes 15-20 minutes
stabilizing the probe and there remains idle during that time.
5 - pH HIGH ALARM. pH Value above which an alarm is generated.
6 - pH LOW ALARM. pH Value below which an alarm is generated.
If the pH probe breaks down, there is a problem in the connection or some other fault occurs
the values read may not be correct. In these cases the values go to one end of the scale,
maximum or minimum possible. To prevent the equipment from working with not correct sig-
nal, alarm values can be programmed.
In the case that the BNC connector has a colored washer, connect the pH probe to the
BLUE.
