Hello

On Nov 28th 2013 I noted LO indicator flashing on my Chlorinator Controller.

Setting was at 20%

Performed Chemistry, Chlorine was off the charts, heavy yellow

Ph was high

Total alkalinity 70

Salinity 3.4

Temp 47 degrees

Prior to removal from service

Flow

Salinity

Temp sensors working properly

Removed from service

Scale build up on probes was observed

Cleaned chlorinator using mix of water and muriatic acid

Returned to service

LO indicator continues to flash.

All sensor points operating normally

Flow and Cell Reversing lights are On

LO continues to flash

Increased Chlorination to 70%

No activity of Chlorinator was noted > No Cell ON indication was created by % increase in chlorine production rate

Turned Power off to controller, waited 5 minutes

Returned to service LO continues to flash and all sensors active.

Cell Reversing light on constantly

Thanks for your assistance.

Todd
