Vac Alarms: removed thermocouple CP4 TE253 channels, silenced EY Cold Cathode for today
Chandra, Dave:
Chandra requested that the CP4 thermocouple alarm channels be removed from the system:
- H0:VAC-MY_CP4_TE253A_REGEN_TEMP_DEGC
- H0:VAC-MY_CP4_TE253A_REGEN_TEMP_DEGC_ERROR
- H0:VAC-MY_CP4_253_REGEN_TEMP_ALRM_INTLK
This was done and the system was restarted.
Also, while contractor work is ongoing at EY, I have bypassed the beam tube CC alarm until 5pm PDT today:
- H0:VAC-EY_Y1_PT423B_PRESS_TORR
