SASE1: Solid attenuator att5 is in error. When it is tried to move it out, the arm lifts, but does not reach the final position before the software time-out. We  increased the software time-out from 4 seconds to 7 seconds, which didn't help. We suspect that there is a mechanical problem that prevents the att5 actuator to reach the out position. 

SPB states that it is ok to leave the attenuator arm in over the weekend, because they run mostly detector tests and don't require full intensity.
