I am having an issue with my system. When the Cell is not plugged into the control box all the lights are functioning on the control panel. When I then plug in my T cell, about 15-20 seconds later all the indicator lights turn off to include also the power light. When you unplug the cell and then turn the power switch to off then on, all lights are functioning again. The system reads 400ppm but an actual test shows 3700ppm of salt. This is the second cell on the system. Any suggestions?
Can the sensor connected to the phone line type jack be the culprit giving false readings? Is there a way to test the sensor?
