As I entered the VEA at X-End I noticed an out place noise, I tracked the noise source to be a noisy power supply at the vacuum rack. Made the report to Filiberto and Richard, noise points to a fan issue.
Filed a FRS ticket, number 35689.
WP12849 Marc is replacing the old PowerTen DC power supply at EX. This supplies the Beckhoff vacuum controls for h0veex. It also supplies the Beckhoff HEPI Pump Controller chassis.
EDC lost 1197 channels when power supply was off (VAC and HPI_PUMPCTRL)
Vac is now back and burt restored at 11:10, we are working on getting the HEPI pump controller back.
Power supply was replaced with Sorensen DCS33-33E supply. Everything powered back up eventually, minor issues with the HEPI controller were solved. This completes WP12849

HEPI controller did not come back on its own. This computer doesn't seem to be set up to start TwinCAT and tcioc automatically. Started both processes manually, but run into an issue that the TwinCAT system was running, but the PLC code was not. After recompiling the PLC code and loading it, the system finally came up.
