During the afternoon shift, we updated DET_MAIN.py in order to use the MOVELIMIT command to close or open the OMC. DET_MAIN node was reloaded at 14h05 utc. Unfortunately after this change the OMC shutter was not opening any more. I also tried to open it directly from the VPM intervace with the MOVELIMIT command (in both directions), but the shutter was not opening. I therefore open manually the shutter using the old command. Changes reverted in DET_MAIN.py.

DET_MAIN reloaded at 15h17 utc.
