How to use Guardian
Accessing to the guardian screen

It pops up the following screen,
Knowing the current state and requested state
How to request a state
Click on the gray bar in the middle.
Then, choose the desired state.
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.
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.
