Aquapure RS cell voltage low

[maropers]

Voltage running about 8 to 9 volts obviously getting an error 120, 121 is my issue the large transfomer?

Looks like a KEA114UL-75V6000-PT

If so is this a captive part or are there any generic replacements?

Welcome to TFP.

Transformers rarely fail. And if they fail they give 0 voltage.

More likley a bad cord or cell. If you replace the cell also replace the cord to it.

How are you testing?

Are you checking the DC voltage going to the cell?

Are you checking the AC voltage from the transformer?

 

[maropers]

I checked the voltage going to the cell. Haven't messed with the transformer voltage.
Three port 1400 aftermarket cell (currently sent back for possible warranty)
New three way sensor
New Zodiac R0467600 Printed Circuit Board (old one was giving the dE fault code)
Salt level at 3700 tested with electronic tester
Water Temp @ 89 - 92 degrees depending on time of day.

Pictures of everything?

 

[maropers]

Salt Cell currently under warranty review

 

[JamesW]

Is that your board?

Can you show pictures of everything including your wiring, transformer etc?

Do you know how to measure voltage?

 

[maropers]

Yes I know how to measure the voltage.

 

[JamesW]

What is the voltage going to the transformer and coming out of the transformer?

Is the transformer wired correctly?

Is there a wiring diagram on the door for 120/240?

 

[JamesW]

As you can see, the primary can be wired for 120 or 240.

The secondary should output 32.5 Volts AC or 37.5 Volts AC.

It think that the controller can select the output of the secondary depending on the current going to the cell.

I think that it chooses the voltage to keep the current more consistent.

You can check the resistance of the primary and secondary windings.

The DC voltage should be 27 volts under load.

You can check the bridge rectifiers.

I did not check the transfomer output voltage. The system has been running as installed for the 4 yrs we have lived here. (we bought the house with the pool in place)

Yes I know how to measure the voltage.

I did not check the transformer output voltage.

If you know how to test, then do the tests.

If you are not testing, where are you getting these numbers?

If you are not testing, where are you getting these numbers?

those were at the salt cell output.

The DC voltage should be 27 volts under load.

You can check the bridge rectifiers.

is this where the rectifier are?

 

[generessler]

In case you don't have it, here is a factory training reference that shows how to measure everything and deduce what's wrong from the measurements. If you step through it, at the end you know what component is bad.

@generessler Thanks for that - I asked for permissoin for access. I found an online version that showed the test points and values as well. The transformer is good however the PIB that I just installed was not BUT it was from amazon and returnable for a new one . I should be back in business in a day or two.
