Help VPI SDS Issue

Hmm, This sort of sounds odd, that VPI's own Table isn't compatible with thier own SDS, then one has to rip into the Turntable, to swap a Cap? Shouldn;t be I say, but if that's what it needs, then that would be the route I would go.

My HW-19 uses a 600rpm Motor, and never had an issue with the SDS, as far as start up.

Yes, the SDS drops to a lower running voltage, but upon start up, the SDS supposed to provide a full 115VAC for a few seconds, then ramp down the voltage to what one selects, or if that has yet to be done, the default voltage that was set by the factory.

This is to give the motor time to come to speed.
If 72V is too low, then yes, try the next higher up, or even two higher up. If you still have issues, definitely contact VPI, I'm sure they'll have some answers. Mark

How do you change the voltage on the SDS?

Call VPI

Even easier. Click this and there is a downloadable manual as well as the calibration information about half way dow the page. The calibration info tell you how to adjust the steps in the voltage.

Hello Drpat.
As Wntrmute stated, the calibration manual is availble in PDF format on VPI's website. The calibration of selecting the "ramp down" voltage is all done via the push buttons on the SDS's front faceplate.

And there's also an hour meter available, you can actually know how many hours of use been placed on your unit.

With my own HW-19 (16lb MK-IV Platter), which had the 600rpm stock Motor, and I'd power up via the Table's on-off switch located on the base, or when I got the VPI SAMA for the HW-19, and decided to power the Table direct from the SDS's switch, never had a problem either way.

More than likely, it would be a problem with the run capacitor on board. Although there just might be that possibility as well, with an ultra heavy platter like the Super Platter, one might have to help it along.

This is something I always commonly do with my own table, as it helps reduce wear and tear on the drive belt. Mark
