Well I think my PLC1400 (just shy of 5 years old) is finally on its last leg... Showing error code 121 (low current in reverse direction to cell). A physical inspection of the inside of the cell does not reveal much... Very minor scaling if any and no damage that stands out... 3,300ppm salt in the pool.
Forward Direction:
5.5 Amps DC (clamp meter)
35.5 Volts DC (measured where cable connects to cell)
Reverse Direction:
2.5 Amps DC (clamp meter)
40.0 Volts DC (measured where cable connects to cell)
I still have chlorine production in the pool and only have the cell set to 30% production... I know it is winter and the pool spends most of the day in the shade this time of year, so I fully expect the demand to increase beyond what this dying cell can handle as we approach spring/summer. Any problem with letting this cell run out until it can't make chlorine anymore? The replacement is going to be a big purchase, so thinking I will let this one run as long as possible?
Also why is my voltage jumping up so high? I remember reading 29-30VDC a few months ago...
