How to know the status of the interferometer

• Look at the monitor here. If "ON", it is in OPERATION mode. If "OFF", it is not; something is strange

screen shots

• If "OFF", check this screen

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

1. 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 will not enter OPERATION state in a few mins, something is wrong. Call interferometer experts.
   • If it is in DOWN state, go to 3.
2. 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. If it will not come back in ~ 10 mins, call interferomter/IOO experts. -- For VIS_PR2 and VIS_BS, the state should be ALIGNED. 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. -- 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.
