CDS maintenace summary

Power cycle h1oaf0 in attempt to fix h1oaf overrun issue.

h1oaf0 was power cycled. The sequence was: kill models, take h1oaf0 out of the Dolphin fabric, power down cpu, power up cpu.

Note: no software was changed, no modified filter files were loaded.

The only restart issue was a brief IRIG-B negative excursion for h1iopoaf0, which invalidated the DAQ data and IPC channels for about 5 minutes.

Unfortunately, this does not fixed the h1oaf0 overrun problem (which started when h1ngn was decommissioned).

DAQ Restart

The DAQ restart was to:

use the latest H1EDCU_HEPIPUMPEX.ini

use a new H1EDCU_SEISMON.ini which I created from the new 6-eq_event code.

WP7346 Vacuum Alarms Reconfiguration

Chandra, Dave:

The cell phone alarm system was reconfigured to:

remove CP4 LN2 pump level alarms (value and error channels) from the system

increase CP4's vacuum gauge alarm level from 1.0e-07 to 5.0e-05 Torr.

The removal of CP4 LN2 pump data has impacted on the daily CP reports, which will require a code change later today.
