    keyword=Interlock glitch caussed laser trip

    All three COMET lasers tripped at around 17:00. When I checked in the laser room, all three lasers showed "interlock error". Then I checked the interlock and found it to be closed. Normally, when the interlocked is broken, it will latch and wait for a manual reset. However, it's not the case this time. So I guess it's due to a voltage glitch of the interlock power supply.
