Pentair Sta-rite pump power out failure

[proluxline]

Hello,
I have a vsp from Pentair and connected to Intermatic 3 circuit board with salt generator, recently when timer goes off and come on I I noticed power out failure on my pump. I called pentair it out of warranty and they said i need to change the whole drive unit as it supposed to keep timer in 96 hours, I was wondering if anyone tired to disassemble the drive unit and was able to change only the capacitor as of my understanding it’s just bad capacitor that doesn’t keep the timer programmed in there. Anyone can suggest what to do, seems the whole drive unite is quite expensive.

Correct. I have not heard anyone who has successfully fixed it.

About $600.

Thank you for your quick reply.

Check the voltage line to line at the pump terminals.

Keep the pump powered all the time and control the pump from the control unit on the drive.

How old is the pump?

Can you show the sticker with the barcode, date and part number?

When you have the Intermatic turn the pump power off, the pump goes into "alarm" mode until all the power in the internal capacitors is drained. The alarm is not saying the internal clock hasn't kept time, only that there is no power to run the pump. It should have constant power and be allowed to "do its own thing" without a separate timeclock. That is not an indication of a problem with the drive.

I agree. The VSP must have it's own line voltage all of the time because it runs on it's own internal timer. That can be the same line voltage that powers your Intermatic timer but it can't be switched on and off by anything. The SWG is all you need to run from your timer and it should keep the SWG from turning on until after the pump turns on and the SWG should be turned off before the pump turns off.
