Issues with valve operations due to a leak in the solenoid valve above FC0. The HPA leak did not allow for sufficient pressure to remain in the lines
to operate. The solenoid as changed this morning.
Thursday, January 18, 2024, 10:32: Roughing. Valves can be cycled. FC0 cycled. OK. |

Tuesday, February 06, 2024, 14:06: Attempted to 'Close' FC0. While it succeeded in moving into position, HPA rushed out of the exhaust. This solenoid
was replaced recently on January 18th. Requires replacement. (ordered)

|
Monday, February 26, 2024, 10:12:
While attempting to cycle FC0, noticed that the turbo pumps TMS:TP6 & TMS:TP2 were off, with TP2 being tripped off. The vacuum on TMS:CG2A
sat around 0.825T although RP2 was running. The ballast plug has since been removed to allow for a 2 hour purge of the roughing pump. |

|
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.
