Quoting Geary Eppley <eppley AT rice.edu>:

Hi Rongrong:

Here are general instructions for the shifts.

****

re: TOF LV alarms

Transient TOF LV alarms (alarms that go away) can be ignored.

Please add: except for temperature alarms.

If an alarm persists, please make a log entry that includes the name of the alarm and the reported value. It is not necessary to powercycle TOF LV. STAR DAQ will powercycle TOF LV when that is required. If you are concerned about a TOF LV alarm and STAR is not running production or cosmics, run pedAsPhys with TOF to make sure the TOF readout is still ok.

*********

If the terminal voltage alarm keeps coming back, you could ask David to raise the limits.

Hello Geary

We see frequent yellow alarms come and go for terminal voltage for VPD West positive. Shall we do anything? Thanks

Best
Rongrong
