We lost the signal from hydrogen and deuterium charts but not from coolant.
So rebooted IOC and turned on the manual heater. But target temperature
kept falling down and the signal didn't come back. So rebooted again.
After 2 minutes the PID worked again and the targets came back to the right
It looks that the manual heater is not working properly so one will have to
test it when beam will be down and make a Halog entry when done.
The test consists of turning off the PID and turning on the manual heater.
If the target temperature keeps falling down, then the manual heater is not
working and we will have to tell the target expert. But don't let the temperature
going below 19 K.
