Summary

As reported in klog 36899, I tried to perform the initial alignment.
During the procedure, ETMY went into the tripped state.
I checked the related signals and found that the GAS F3 signal had been gradually increasing since yesterday. This issue needs further investigation and treatment.

Details

During the initial alignment procedure, I requested IRY_LOCKED in the initial alignment GRD. Then, ETMY was tripped.

The trip seemed to be triggered by a large signal K1:VIS-ETMY_F2_WD_AC_BANDLIM_GAS_OUT16. (fig_001)

I cleared the suspension trip and checked the GAS signals. I found that the F3 signal had started to increase suddenly last night, although this signal had already been relatively large before. (fig_002)
Also, it seems that the GASs were oscillating in the LOCK_ACQUISITION state. (fig_003)

(The suspension can be state at the MISALIGNED state, which had been kept overnight.)
