New member, I'm not a pool owner, but my friend is. I am a master electrician and have inherited the task of figuring out his pool problem. The unit is a cpsc36 and is giving a "high salt" indicator light. There were no bubbles being generated by the generator unit. He called the company and was told to calibrate the unit. It shows +18 on polarity 1, and +16 on polarity 2. Calibrating the unit made no difference.
I found that the wires feeding the primary of the transformer had been pinched in two. Upon reconnecting these conductors, the generator began to make some bubbles, but not the usual amount and the indicator light remained on. I checked the voltage going out to the generator and found 4 VDC with 15 amps of current. Per the chart it should read 30 amps. The transformer lists a secondary voltage output of 8 - 36 volts.
With the voltage AND the amperage being exactly half of what I think I should see, I am left to assume that I have lost, at least, one of the rectifiers (SCR's I think). That would account for the reading. The other thought is that with the "high salt" reading, the controller is turning off part of the SCR's and is trying to reduce the amount of generation. I can check the SCR's, but it will probably require removing them from the unit to get an absolute reading and I'm reluctant to do that unless it's the only option.
Does anyone else have any experience with this set of circumstances? Does anyone know where I can get a wiring schematic?
Thanks for any help.
