High reading on RAMSES sensor

We observe an increased reading on one of the RAMSES sensors (located in the miniframe), which seem to be related to activities of the machine. These values show up in red in the 'environment panel', RAMSES tab:

Click on the value to see the historical trend, and you will notice this value is correlated with activities in the machine. Values up to a few hundred has been observed.

Do not worry when you see values in red when there is beam in the machine. In case you see values in red with no beam in the machine, make a note of it in the logbook.

Recurrent DSS alarms

Currently a few recurrent alarms are observed on the DSS screen:

  • Water leak in CR4:WL1.pngThis is due to condensation water dripping from an iced water pipe. No further action is needed on this alarm.

  • Water leax in UX (below laser):WL2.pngThis is due to condensation water from a cold cooling pipe on the SPD cooling pump in front of the L3 magnet door. This alarm might come and go; no further action is needed on this alarm.

  • SPD temperature warnings (AI_SPD_SECTx_y_CHz): AI_SPD.pngThese are warnings from the SPD temperature monitoring system. These warnings might come and go; make a note of them in the DCS logbook, no further action is needed on these warnings.

  • Ambient temperature (in cavern) warnings (PT_UX_xx_Temperature): PT1.pngThese are warnings on ambient temperatures in the cavern hovering around the (upper) warning limit, especially when we higher warm outside temperatures. These warnings might come and go; make a note of them in the DCS logbook, no further action is needed on these warnings.
