[dsg-hdice] 30 V supply

[Peter Bonneau]

Xiangdong,

If you're back from vacation, we have the 30 VDC supply that you've ordered.
We can meet if you want to discuss the next steps with this supply.

Our next scheduled meeting is July 18th since next Thursday is the July 4th holiday.

Peter

Andy,

Just to keep everyone in the loop we checked the power supply voltages, everything looked okay.

The stepper motor that drives the proportional valve was spinning as well.

We'll have to wait until Wei returns to do anything else since I'm not really sure what he wanted to do with the 30 VDC supply as nothing in the schematics calls for that voltage.

He'd like to see if it matches your previous measurements (taken before the installation of the other new power supply). If you're not sure which valve this is, I can show you.
