Jandy Truclear SWG No Output Issue

We installed a pool in 08/19. The pool contractor installed a Jandy SWG. The system operated great until 07/22. At that time the power pack displayed a “Check Cell” indication. I called my pool contractor and he replaced the cell under a three warranty. We were back in business until 09/23 when the cell began to leak badly. I called my pool contractor, who once again replaced the cell under warranty. Yesterday, I noted there were no bubbles in the cell window, thus no chlorine is being produced. The power pack display is normal and displaying % Chlorination as it should. I cycled the power to the power pack and still no bubbles. I assume the cell has failed after 13 months. Calling my pool contractor, he stated the cell was only warranted for 12 months. Before purchasing a new cell I wanted to know if there is any check I can make to verify it is the cell, as opposed to the power pack, that has failed.

My second question concerns the wiring of my Truclear Power Pack. While studying the cell failure issue noted above, I read the power pack should be wired such that it powers on/off with the pump turning on/off. The Truclear SWG is wired to its own breaker and has power continuously. I have a Jandy 1.65 THP VS pump that is also wired to an individual breaker. The pump circulates water 12 hours a day. When the pump shuts down, the SWG displays “No Flow”, but does not power down. I understand there is no chlorine being generated in this condition. Is there a detriment to the SWG being powered up all the time? I do not have an automation system, so I would need to install one, or find another way to cycle the SWG power.

Thanks for any and all inputs.

I would not use lack of bubbles as the indicator that your cell is not generating. You say the power pack display is normal.

What pool test kit do you use?

What is your FC level?

Does your pool pass a Overnight Chlorine Loss Test?

The Jandy TruClear Installation Manual says:

The power pack must be interlocked/interconnected with the pool pump motor power source to ensure that the chlorinator only operates when the pool pump is operating. The flow sensor feature of the Jandy TruClear is intended to be used as a backup only and should not be used as the sole source of flow detection.

The Jandy TruClear chlorination system with Firmware Revision F or later, can monitor the state of the Jandy Variable Speed Pump so that the TruClear does not operate if the Jandy Variable Speed Pump is not running.

A four wire RS-485 cable is connected between the TruClear Power Pack and the Jandy VS Pump to ensure that the chlorinator only operates when the pool pump is running. With this connection no timer for the TruClear is required.

Once connection has been made, the TruClear User Interface (UI) should display “Standby #”.

Thanks AJW22 for the reply. To answer your question my FC is 3.0. I went over all the connections and could not find anything that was odd. I was under the assumption I needed a new SGW cell. I decided to call the company who installed the system. To my surprise, they had ceased operation, due to the owner having a massive heart attack. He still had the same number and answered. He agreed that the presence of bubbles was not what I should worry about. I still was concerned I had a bad cell. The following morning I went to look the system over again and everything was working, bubbles and all. Go figure huh? It has not missed a beat since. I have no idea why it was not working for a few days. I suspect I will see this issue again.

I spent today looking at the diagram you forwarded and compared it to my system. I do not have an automation system, so in order to control the SWG with the cycling of the pump, there would have to be some sort of external relay. The drawing seems to indicate the SWG power is switched by the pump at L1 and L2. Looking at the manual for that specific pump, I see L1 and L2 are the input power to the pump, not an output. My 1.65 THP VS Pump only has L1 and L2 input power and no pump controller switched output power for the SWG. I can not locate a place to attach an external relay for SWG input power control. The only way I see to switch the SWG power is to add a separate timer or add an automation system. Am I wrong?

Thanks again for your time.

God Bless

AJW22 you have opened my eyes....and made me tear up at the same time. I have a copy of what appears to be the same manual you forwarded me the link to. In the manual I have, page 16, paragraph 3.7, is titled "Bonding". In the manual you provided page 16, paragraph 3.7 is titled "When Using In Non-automation Installations And With Jandy VariableSpeed Pump". That paragraph does not exist in the manual that accompanied my TruClear SWG. My manual only describes connecting the TruClear SWG to a Jandy Automation system via RS485, nothing whatsoever about connecting directly to a VS pump. My manual does not reference anything about Firmware Revisions. I now see Firmware "F" is required and my system is running Firmware "D1". No where can I find that this Firmware can be update in the field.

In the end it appears in order for the Pump and SWG to cycle on/off together, I would have to add some form of automation, or get an updated SWG controller. I am not sure if I will pursue either option at this time. I guess I will just let the Flow Switch continue to cycle the SWG on/off as it has done since installation. I know it is not the preferred way to operate, but winter is near, and I'll think it over during the cool weather.

I again appreciate the input, and this site, that allows information to be shared.

God Bless,

Tony
 
Welcome to Jandy land where most of their equipment cannot be updated.

Jandy likes their equipment to be disposable and sell you new stuff rather then make it upgradeable.
