| **Usual alarm types and response:** | **Usual alarm types and response:** | ||
| - | You need to log on gln1, see [[LN computer]]. | + | 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. Get familiar with the commands mon, clr, ton, fill, coff, con, abort, load, quit | ||
| + | |||
| + | In some cases you need to edit the fill-system configuration file ~/scripts/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! You can't say 'load' | ||
| + | while the system is filling. Sometimes you also need to exit and start the UI again before it allows you to execute 'load'. | ||
| + | |||
| + | IN WORST CASE: You can always hand-fill a quad in any mounting position. | ||
| __Long fill__ | __Long fill__ | ||
| + | * What happened: The LN outlet sensor hasn't triggered. | ||
| + | * Run run-gln-ui.sh | ||
| + | * Say 'clr' to clear the alarm | ||
| + | * Check 'Fill Temperature Plot' if this sensor got cold | ||
| + | * If this happens regularly you may want to increase its trigger threshold in gln.fig (F1 directive, beginning in 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 (spike)__ | ||
| + | * 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 (ton #det) | ||
| + | * If this happens regularly you may want to increase the T high threshold in gln.fig (F3 directive, end in gln.fig) | ||
| + | |||
| + | __Detector warm II__ | ||
| + | * What happened: Detector runs out of LN and really warms up | ||
| + | * IMPORTANT: detector T increased by few Kelvin only, see plot from **real-life example** (below). | ||
| + | * Run run-gln-ui.sh | ||
| + | * Say 'fill det#', confirm that you really want to fill it. | ||
| + | * Say 'coff det#', this stops T checking (and alarming and disabling) of this detector | ||
| + | * Watch the fill, check for reasonable fill time (not that LN out is triggering much too early) | ||
| + | * After fill, within ~30 min the temperature should recover (see example plot below). | ||
| + | * If T is good say 'con #det', so T checking is enabled again. | ||
| + | * If it is deep in the night: You can temporary increase T high threshold (F3 directive) | ||
| + | * NEVER LEAVE DETECTOR WITH T CHECKED TURNED OFF | ||
| + | |||
| + | |||
| + | |||
| + | Here a **real-life example**. After alarm got received you get following T-plot: | ||
| + | {{:fillsystem:warm-up-example.pdf|}}. Actually after alarm you get it up to | ||
| + | channel ~1100 and see T is going up. Therefore it is a real alarm. Next you do | ||
| + | is logging on the gln system, run the UI, and say 'fill 6 now'. Then clr and directly | ||
| + | coff 6 (as a fill enables T checking by default). Later you see how T is recovering. | ||
