How to know the status of the interferometer
- Look at one of the TV monitor in the control room. If "ON", it is in OPERATION mode.
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.
