| 7 | | - when you reach the [[https://www.fact-project.org/logbook/misc.php?page=limits | Datataking Limits]] **stop datataking**! |
| | 7 | - Monitor the system and in special the currents |
| | 8 | - limits for the currents are defined in the DatatakingLimits |
| | 9 | - if the limits for the currents are exceeded you have to stop datataking: |
| | 10 | - stop the script (dimctrl --stop from a bash) |
| | 11 | - stop Trigger (MCP/STOP or FTM_CONTROL/STOP_TRIGGER |
| | 12 | - ramp down the voltage (BIAS_CONTROL/SET_ZERO_VOLTAGE) |
| | 13 | - close open files (FAD_CONTROL/CLOSE_OPEN_FILES) |
| | 14 | - adapt your schedule (edit ~/operation/scripts/schedule.js) and update the schedule (dimctrl --quit --cmd ".js scripts/updateSchedule.js") Note, that only entries which are schedules for *now* or the future are transferred to the database. All previous entries stay like they are. |
| | 15 | - you can write also your own schedule file and transfer its content to the database by given the filepath to the command: (dimctrl --quit --cmd ".js scripts/updateSchedule.js file=<!pathToScheduleFile>") |
| | 16 | - Be aware of all other DatatakingLimits |

| | 27 | = Limits for running the System |
| | 28 | |
| | 29 | |
| | 30 | || value || max || action || additional information || |
| | 31 | || __Currents__ || |
| | 32 | || median current per pixel in camera: || 90 uA || stop script, ramp down voltage || displayed in smartfact (mainpage, line 'GAPD') || |
| | 33 | ||maximum current in a single pixel: || 110 uA || stop script, ramp down voltage || the crazy pixels are excluded from this limit || |
| | 34 | || __Temperature__ || |
| | 35 | || temperature difference: || 7° C || monitor the temperatures carefully || _difference between sensor compartment and outside temperature_ || |
| | 36 | || temperature difference:|| 15° C || stop data taking || _difference between sensor compartment and outside temperature_ || |
| | 37 | || temperature in container :|| 40° C || do not observe when the temperature in the container is above 40 deg || |
| | 38 | || __Drive system__ || |
| | 39 | || Zenith angle:|| ~75° || || data with higher zenith do not make much sense || |
| | 40 | || Zenith angle:|| ~88° || stop data taking on this source, look for a source with smaller zd || || |
| | 41 | || __Wind__ || |
| | 42 | || Wind speed|| exceeds 50km/h significantly or in regular intervals || bring telescope to parking position and wait for better wind situations || || |
| | 43 | || __Weather__ || |
| | 44 | || Clouds || no stars visible in allsky camera in pointing direction || stop datataking, you may continue tracking the source or observe another source in case stars are visible in that direction || || |
| | 45 | || Rain || it is raining || stop script, close camera || we need rain sensor to identify rain clearly || |
| | 46 | || clouded mirrors/water on mirrors or light pulser || do not observe, wait until water is gone || you may check with IR camera || |
| | 47 | || Humidity || - || check general weather condition, especially if it is raining || high humidity (there is a warning at 98%) alone is not a reason to stop || |
