• Open the Guardian screen (link on the PMC screen)

• 1. Request "PSL_LOCKED"
• 2. Execute (Choose "EXEC")

• Make sure that PMC is locked with the StripTool, PMC_TRANS camera, and the Guardian. If K1:PSL-PMC_TRANS_DC_OUTPUT ~ 6, PMC is locked. If K1:PSL-PMC_TRANS_DC_OUTPUT ~ 0, unlocked.

IMC

Lock IMC

• Check MCI, MCO and MCE (link to VIS page. DC alignment values, Watchdog, Dackill)
• Open IMC medm from sitemap

• Open StripTools and Guardian from IMC medm

• The usage of the IMC Guardian is almost same as one of PMC. Request "IMC_LOCKED" and execute.
• NOTE: If PMC is unlocked, you will see a message "PSL_is_unlocked!" in USERMSG line in the IMC Guardian. When you see it, check if PMC is locked or not

• Open StripTool /users/stiptool/IMC.stp

• Find MCE_TRANS camera

• Make sure IMC is locked with the StripTool, MCE_TRANS camera, and the Guardian. If K1:IMC-MCL_TRANS_OUTPUT ~ 0.40 - 0.46 , IMC is locked. If K1:IMC-MCL_TRANS_OUTPUT ~ 0.020, unlocked.

Main IFO

Lock Michelson IFO

• Open /users/striptool/REFLPD_RMS.stp. You can see REFL PDA1

• Control panel for MICH length-sensing control (LSC) is sitemap => LSC => iKAGRA LSC
