SWG turns off prematurely?

[mchaos]

Hello all,

My pool is about 6 months old and I am still trying to figure out all its "idiosyncracies." Lately, I have been testing FC twice a day because I can't seem to keep it stable. I have cranked the SWG up to 90% and the FC has been increasing by barely 0.5 ppm per day, which makes little sense to me since I run the system for 9 hours a day. Yesterday I noticed that about two hours after the pump system turns on the SWG turns off with the message "chlorinator off, setting met." I turned it on manually and the FC increased way more than it had been. Today, it did the same thing. I would expect the SWG to run about 8 hours if the setting is at 90% and the timer is set to run for 9 hours. Have any of you come across a similar issue? Am I missing something? Just thought I would check in here before I reach out to the pool company.

Thank you for your responses.

Cheers,
Marcos

Just in case it is relevant, here are the latest chemistry readings as of this morning:

FC - 4 ppm
CC - 0.2 ppm
TA - 80 ppm
CH - 320 ppm
pH - 7.6
CYA - 70 ppm

The readings from the salt cell are 25.8V, 6.5A, and 2800 ppm of salt

Your SWG running at 90% for 9 hours in your 13,500 gallon pool will generate 4.2ppm of FC per day.

Your pool using 3.7ppm of FC per day at this time of year in FL is very reasonable leaving an excess of 0.5ppm.

Thank you for your response,

If this behavior is reasonable, then I am a little confused as to why the SWG is apparently shutting off two hours after the system turns on for the day presumably after having reached its % setting according to the message on the screen.

I think it just depends when you look at the panel.

Your system has a cycle time of 180 minutes. At 90% it will generate for 162 minutes and rest for 18 minutes, and then repeat.

Thank you for this. As I suspected, I was unaware of this very relevant information.
