The TSH:TGHT stopped at 263.7A, but the setpoint is still ramping (now at 421A). The voltage is set correctly: have 6.238V setpoint and 4.386V readback.
The reading on the Power Supply shows 418A. Through the window the target assembly looks at high temperature. The readback on Epics seems stuck.

Monday, April 15, 2024, 14:33: On Friday it was noted that the EE was being troublesome. If we put -500 V on the EE the PS would deliver -1000 V. However
it would slowly trickle downward. elog:1002.

in EPICS because the "TSGBIASSAFETY ok" interlock is tripped. No idea what this means - maybe it checks for AC power?

Both turbo pumps at the source box were found off. TSG:TP1A has been started normally. TSG:TP1B does not spin up above 3KRPM even after several attemps.
A fault report has been send to vacuum group.

Corrected title from off to timed out . It seems the controller lost contact with the pump when I touched the rack. The pump recovered right back
