tests
The plot:ConfigDASMuvi1Tel4mufeeX.png shows the situation on the Mufee card when the cooling system was blocked (ice in the tube! there was water inside instead of alcohol) on Wednesday 25th. cf there was 47°C on MufeeX mate of Telescope 4.
The voltages on Must2 tripped, due to the increase of temperature on the Mates. After fixing the problem, the Mate temperatures were decreasing from 40-47°C to 19°C when the system was running again in normal temperature conditions (cooling system running well again, at -10°C).
The second one ConfigDASMuvi1Tel5mufeeXokTemp.png (Telescope 5) shows Mate for Tel.5 with T around 19°C.
When the temperature is set at -10°C on the cooling machine, and when we run in normal conditions, after stabilizing the temperature inside the chamber, the standard conditions on the Mates are around 7-12°C (depending on the position of the telescope on the chain of cooling tubes, close or not to the entrance or exit tubes).
To read the temperatures on the Mate, we need to have the low voltages on, and the software Das online. |
