Check list of the interferometer

Look at the Guardian overview, check if all of VIS Guardians are in ALIGNED state

OR you can see the VIS status on the Monitor

• 

• If the Guardian is in TRIPPED state, you should reset Watch Dogs (WDs),

OR call operation shift members (contact person TBD).

Check the IO Guardian

IO Guardian should in PROVIDING_STABLE_LIGHT state, if not call operation shift members ASAP!!!(contact person TBD).

Check the Green Laser status

• see if the shutter is on or not

• see if K1: ALS-X (Y)_ARM_INPUT_OUT is more than 0.7

• Check if ALS_PLLX/ALS_PLLY Guardian is on PLL_LOCK state

If "OFF", check the guardian overview screen

Check the state of LSC_MICH. First check if the request state of LSC_MICH is OPERATION. If it is not, request OPERATION.

• If the state is READY, ENGAGE_SERVO, ENGAGE_BOOST, MICH_LOCKED, CALIBRATION_INJECTION, or ACTUATORCAL_INJECTION, the interferometer is now on the way to be OPERATION state. It will be ready soon.
  If it does not enter OPERATION state in a few mins. Call the interferometer experts.
  Check the status of IMC_LOCK, VIS_BS, VIS_PR2, VIS_PR3. (Note that VIS_PRM is not used for now, so just ignore it)
  For IMC_LOCK, every thing should be green and IMC should be back automatically.
  
  For example, this is how the IMC_LOCK guardian should normally look like.
  
  If it does not come back in ~ 10 mins, call interferometer/IOO experts.
  For VIS_PR2 and VIS_BS, the state should be ALIGNED. If inot, a notification "please reset Watch Dog!" will show up, and the state is in TRIPPED. In that case, go to the next section to know how to reset Watch Dog.
  For VIS_PR3, the state should be DAMPED. If it is not, a notification "please reset Watch Dog!" will show up, and the state is in TRIPPED. In that case, go to the next section to know how to reset Watch Dog.
