First of all the fast shutter is closed before moving the filter wheel (to protect the filters during moving) and blocked till the movement is over. Then the fast shutter has to be opened again with the Fast shutter control button. It does not open automatically!

13 -In addition the pulse energy and the number of bunches in the FEL is monitored. IF the radiation dose exceeds a certain limit the filters can not be moved into the beam. Then the beam has to be attenuated using the gas attenuator to a range where the filters can be used again.
