I was paged in this morning for two probelms:
1) Alarm handler not working.
2) Lifter indicator was not working while in LH2 no rad position
during the night shift.
It was found that ioc was dead. So rebooted ioc. After rebooting, the target
was found in LH2 no rad position! (While before reboot, it was in optics target
position). I moved the target to optics again, it seems fine. Re-entered all the
alarm set values. The save alerm to default file not working yet. Informed
Chris Keith about the alarm default issue and the lift moving by it self due to
rebooting. It should not happen and possiblly somebody clicked the LH2 no-rad
position while ioc died (though checking with the target operator, nobody clicked).
We need to be careful with the lifter and try to minimize motion.
Also asked Chris to change target vertical encoder by 2 mm (target
was high by 3.5 mm). When he finishes, we will need to reboot to have the new
values in effect. Also the high power heater default set point is 22 K for loop 3,
Chris will work to let it take the modified value (19K).
For now, after reboot, one needs to check the HP heater PID set value and change
to 19K if it is not 19K already. Also need to manually enter all teh appropriate alarm
IOC dead one more time by itself, and rebooted.
