T-CELL Voltage Sensor Short Chlorinator1

Jump to latest Follow Reply
I am also having the same 3 error messages with no other issues. The errors clear and my salt and chlorine levels are good according to Taylor kit measurements. I am wondering if this could be a firmware issue.
 
I just started getting the same errors again - my equipment is less than 2 years old.
CHLOR Relay K2 Stuck Open Chlorinator1
T-CELL Current Sensor Short Chlorinator1
CHLOR Relay K1 Stuck Open Chlorinator1

My observations:
Salt cell is working based on my measurements using TAYLOR TECHNOLOGIES INC K-1766 DROP TEST CHLORIDE SALT WATER.
Salt cell (TCELL940-w) does read too high -
When cell is "operating" I see bubbles coming from returns.
Firmware update "seems" to have no effect, unless latest has caused errors to reappear.
This issue is intermittent and clears on it's own
Replaced HLX-PCB-TCELL based on recommendation from Hayward - still getting errors.
The HLX-PCB-TCELL board has no chips or discrete components - it is merely a connector extender.

Does anyone have any useful information on this problem they can offer?
 
The HLX-PCB-TCELL is just an interface board, it has no electronics.

The K1 & K2 relays are on the main board. More than likely, it is either a solder issue, which is common with the relays, or a failed relay or a failed relay driver. It is possible to replace the relays if you know how to solder.
 
Mark - thanks for your reply; and yes, as I stated, the HLX-PCB-TCELL is merely a connector extender I don't know why Hayward told me to replace. Because the errors are intermittent, I am skeptical of a hard failure of the relays or relay driver. Moreover, a bad relay gets progressively worse and eventually fails from my experience. A cold solder joint could be causing this IMO. I know how to solder and have the equipment required; however, getting a part number for the relays is the problem. Do you have a part number? In any event, I have a 5-year warranty so I will just try to get Hayward to fix. I think the problem is perhaps timing related in the software or marginal discrete components on the main board.
 
Mark - thanks for your reply. New update today. These errors remain on the IOS app:

CHLOR Relay K2 Stuck Open Chlorinator1
CHLOR Relay K1 Stuck Open Chlorinator1

The Omnilogic panel shows NO errors at all. I have bubbles coming out of the returns. While "chlorinating", the cell current (5.77A), voltage (26.21V) and salt readings (3600/3677) appear to be normal and change. I verified salt with strips and Taylor K-1766 salt test kit - all within specs. Where is the fault? If the relays were open, there would be no current flow - correct?

It appears that the IOS errors are erroneous and may be a result of the recent IOS app update 4.7.20. What do you think? I prepared a Word document with pictures of all this that I am going to send to Hayward. I reported a problem, with the IOS app, in the past showing different wattage readings (IOS app vs. panel screen) for the pump and Hayward responded and fixed. I'm hoping my current errors may also be app related and my board is OK. My equipment is still under warranty so if not the app, I will ask for a new board. I just hate to have the board replaced if not really the problem.

Thanks again for your help.
 
Ignore the app. What matters is what is on the display attached to unit.

Yes, most likely an app issue. I misunderstood your original post on where the error was occur.
 
I sent a very detailed document to Hayward and this is their response:

The error you are receiving are not a result of the IOS update. Normally when you see these 2 errors this is pointing to an issue with the t-cell board. I understand they do clear them selves, but you should not be receiving these errors. I would recommend getting a local warranty center onsite to check the system
Also with the cell unplugged check the cord end to see if it is showing signs of being burnt, and also look at the t-cell board were the cell plugs in.

I just don't understand this response when the photos clearly show that the errors are not on the Omnilogic display panel.

Did you try uninstalling the app and reinstalling it?

Is there a web based version you can look at from a PC?
 
My point is: they didn't even acknowledge what is displayed on the Omnilogic display should be the deciding factor. Errors are on two different versions of IOS. Will try again - thanks.
Good question about PC version. Does anyone know? I googled and got requests to install other software, so I ignored.
 
If I remember correctly, you can type the ip address of the unit into a browser and it has an internal web page.

I forgot we had this noted at Hayward Aquarite SWG - Further Reading

Check the 4 amp mini fuse on the main board.

Burnt T-Cell Connector Plug​

Hayward Aquarite Burnt T-Cell Plug.jpg

Getting the messages below indicates a blown fuse 4 amp mini on the main board or a burnt T-Cell plug:
  • T-cell current sensor short
  • T-cell voltage sensor short
  • Chlor relay K-1 stuck open
  • chlor relay K-2 stuck open

The plug is a Molex 76650-0078 plug

The connector header on the pcb is Molex 00015246101, Digi-Key Part# WM7188-ND. EBay "15-24-6106 MOLEX CONN HEADER 10 POSITION 4.2mm VERT TIN" has been a source for it. It's an exact fitment except it's off white.

Awj22 - thanks for the info. If my plug looks good and, as stated above all indications look good - is there a need to check the 4A fuse? Again, no alarms on the main OmniLogic panel.

Yes, I would check the fuse.
 
Update - uninstalled, reinstalled Omnilogic app from all IOS devices and errors remained. Removed power from pool system and rebooted - errors are cleared. Will see if they return. IMO, absolutely no reason to check fuse if you have NO ALARMS ON PANEL, changing current & voltage and bubbles coming out of your returns. And as mas95 said, "Ignore the app. What matters is what is on the display attached to unit." Totally agree with this. Thanks for your input.
 
It is just very odd that the app would display different information than the physical display. As long as it is generating CL, then it should ok.

Just one thought is that the error may have occurred at one point but did not clear from the app for some reason.
