Hi all, I have a Zodiac Tri Large PH for about 5 years ago for which I kindly seek your advice.
I had the feeling that it didn't produce enough chlorine, but I can't be sure about that as I can't measure chlorine output, so I went through the trouble shooting guide.
The guide says that it should measure between 21V and 24 V at the cell output contacts, if outside these values it indicates a nominal amperage issue.
I measure about 23 V at the cell output contacts at start up, but this will gradually decrease to settle around 19 V after about 5 minutes, which according to the trouble shooting guide indicates a nominal amperage problem.
I then measure the current at the cell contacts and this reads 7.22 A and will gradually increase to +7.3 A, so this seems normal figures as the guide says the Tri Large should measure 7.2 A.
Some additional observations I did.
(1) When the voltage is at 19 V and I open the water supply, which feeds into the suction side of the pool pump and will actually dilute the salt content of the water going through the cell, the voltage will climb again to about 20 V.
(2) When I cut the mains power to the unit , and even disconnect the cell from the unit, I will still measure 2 V at the cell contacts which will very slowly decrease, but there will always remain a voltage.
So my question is if these observations are normal behavior or does this indicate a problem ? If the latter, is the problem with the power supply or the chlorinator cell?
Thanks in advance
I include a link to the repair manual so you can verify the figures.

Edit for some speeling mistakes.
