|
The gas system has been checked. The variable valve opens at about 7.55 very fast. Please be careful when using it. Stepsize for opening around this
value should be 0.01. Gas lines have been pumped with pump in the high voltage rack. Ne leak was opened to release pressure. |

Both turbo pumps at the source box were found off. TSG:TP1A has been started normally. TSG:TP1B does not spin up above 3KRPM even after several attemps.
A fault report has been send to vacuum group.
