Usual alarm types and response:

You need to log on gln1, see LN computer. Go to directory ~/scripts and run ./run-gln-ui.sh which gives the fill system interface. Type help for getting overview on commands.

In some cases you need to edit the fill-system configuration file ~/gln/gln.fig for setting new temperature thresholds. In order to apply new gln.fig configuration you need to say 'load' in run-gln-ui.sh and MUST RE-ENABLE the filling!

Long fill

• What happened: The LN outlet sensor hasn't triggered.
• Run run-gln-ui.sh
• Say 'clr' to clear the alarm
• Check 'Fill Duration Plot' if this sensor got cold
• If this happens regularly you may want to increase its trigger threshold in gln.fig (F1 directive, beginning at gln.fig)

Detector warm

• You get a detector high temperature alarm.
• Check 'all zoom cold (pdf)' plot.
• T-plot for detector is just straight: Go to Detector warm I (spike)
• T-plot for detector shows exp-like increase: Go to Detector warm II

Detector warm I

• What happened: T read spiked and caused T high alarm
• Run run-gln-ui.sh
• Say 'clr' to clear alarm
• You need to re-enable filling of this detector
