Salt cell turn off after 30-40 minutes

My salt cell turns off after 30-40 minutes of operation. If I reset it, it will run another 30-40 minutes. It is a T-Cell-15 (40,000 gallon). The salt cell is 4 years old and I run it at 35%. I remove and clean it every fall. The 'inspect cell' error message is always on, but I think it works sometimes because of the voltage readings, however the voltage, current, and salt readings change over time during the 30-40 minutes it is operating. I attached a file with the readings. The actual salt level is about 3200. The controller is a AQL-PS-4. Anybody know what the problem is? Thanks.

Hayward SWG run on a 180 minute cycle. If you set 50% it will be on 90 min then off 90, then repeat. At 35% setting it should be on 63 minutes then off for 117. Have you checked and cleaned the cell? After cleaning cell you need to press the button next to the display and hold for 5 seconds to reset.

It turns off after 30-40 minutes and never turns back on again. I will change the setting to be on 70% and see if there is any difference. The cell is clean and I do not know how to check it other than that. Thanks.
 
What are the first seven characters of the cell and box serial numbers?

What is the actual salinity and how are you measuring it?

What is the T-cell size?

Is the T-cell size set correctly in settings?

To get the performance percentage of the cell, divide the instant salinity reading by the actual salinity reading.

You need to be really sure about the actual salinity reading.

You need to use a K-1766 salt test kit or a calibrated meter.

Note that ProLogic, AquaLogic and AquaPlus use the Hayward T Cell.

However, the procedure to get the diagnostic readings is different.

Here is the procedure for ProLogic, AquaLogic and AquaPlus:

Go to the diagnostic screen, note the readings and then press the + button to reverse the polarity.

When the new numbers appear, see what they are.

Then, press + again and note the new readings.

I use a Taylor kit for the salt level and it is 3200. I do not think there is a setting for the cell type/size in my controller (see photo). It is a T-Cell-15 (40,00 gal). I get the serial numbers as soon as I can. Thanks.

The T Cell 15 (40,000 gal) serial number is 3E16362-204073. I could not find a serial number on the Aqua Logic control box. There is a serial number on the controller board. I attached a picture so you exactly where it is from. This morning the salt cell is reading about 27v and 5.7a. The salt reading on the diagnostic menu is reading 2800 and the salt reading on the default menu is reading 3400. The actual salt concentration is 3200. Thanks.

How are you controlling the Intelliflo pump?

What is the pump speed?

What is the filter pressure?

Does it say “No Flow” in diagnostics when the pump is off?

Turn the chlorinator percentage to zero, then turn the pump off at the pump control panel and then check the diagnostics to see if it says “No Flow”.

Controlling the pump with the Aqua logic. The Aqua Logic is old and does not have multiple speed control for the pump.
The pump speed is 2950 RPM
The filter pressure is 23 PSI
It says "no flow" in diagnostics when the pump is off
With the chlorinator to zero and the pump off at the pump control panel, it says no flow.
When I put it back to normal the salt cell readings are now -26.3 v, -6.4a, and 3300 ppm salt. Should the salt cell reading drift when it is on?
Thanks

The cell is about 5 years old and the performance in both polarities is beginning to drift a little bit, but I don’t see any reason that the cell would turn off and not come back on.

The cycle time should be 120 or 180 minutes.

Change the percentage to 50% and watch the diagnostics.

Check the diagnostics after about 60 minutes.

If the cell is still on, check the diagnostics after 90 minutes to see when it turns off.

Once the cell turns off, it should come back on in 60 or 90 minutes, whichever your cycle time is.

If the cell does not come back on in the 60 to 90 minutes, go through the full diagnostics menu to see if there is some sort of error message.
 
Are you controlling the Intelliflo by the filter pump relay cutting power on and off?

If yes, you should change it to constant power and use the pump’s onboard control settings to control the pump.

You would set the filter relay timer to match the pump timer settings so that the SWG is never on when the pump is scheduled to be off.

Is the filter relay set as a single speed pump in settings?

The serial number for the box should be on the inside of the door and it should start with something like 5L08.

I am assuming that the relay is cutting the power on and off. As far as I know there is only the option for a single speed pump. I will investigate that and make the appropriate changes you suggest.

There is no serial number in the box.

I checked the salt cell timing and it is a 120 minute cycle. The salt cell seems to be functioning properly now. The only thing I noticed is that the salt reading in the diagnostic menu varies between 2500 and 3400. Is that normal? Thanks

If the instant salinity is significantly different in one polarity vs. the other polarity, then the cell is failing.

Check for scale and clean if necessary, but only if necessary.

My apologies. I was looking for a metal serial number plate. The serial number is 5L0507-1007823.

The salt readings go from about 3400 to about 2500 over a one hour period for both polarities. The current also decreases about 1a over the same period.

Thanks
