At 09:27 UT DECam gave us the alarm "DECam OCS lost connection Interlock (SISPI) is now broken”. We tried RESET and CONFIGURE and did not work. Claudio sent the telescope to Zenith, in case the problem was from the TCS. The telescope moved to that position. We tried RESET and CONFIGURE again without positive results. We decide to restart SISPI. The interlock problem was fixed, however, Claudio told me TCS showed no connection with DECam. We took some zeros and it worked but when we tried to load one object, we had the error "TCS INTERFACE FAILED: TCS IS NOT READY. STATUS NOT CONNECTED". We did a RESET and it worked. However, Claudio told me TCS was not able to see DECam as connected. We restarted again SISPI with "architect -c DES.ini" command because "architect -c eric.ini" did not work. After this we had another trouble, Vsub was yellow… I check the notes in the DECam support pages. We checked the crates and Claudio told me they were all working. We followed the instructions that are in the DECam Support Pages and wrote the command "get vsub details" into the Architect Console and nothing happened… Vsub is still in yellow... We did not know what else to do...
