• We found that the MN_OLDCCTL_Y seemed to kick  the ETMX suspension, and it seemed that this was due to the following setting the in TypeA guardian. At least after this modification, the we could reach the ALIGNED state without any problems.

# ---- #
        for DOF in ['P','Y']:
            #[FIXME] not cool
            if optic in ['ITMX','ITMY','ETMY']:
                ezca.switch('VIS-'+ optic +'_MN_OLDCCTRL_Y','OUTPUT','FM1','FM2','FM3','FM6','FM8','FM7','ON','INPUT','FM4','FM5','FM9','FM10','OFFSET','OFF')
            else:
#                ezca.switch('VIS-'+ optic +'_MN_OLDCCTRL_Y','OUTPUT','FM1','FM2','FM3','FM4','FM8','FM9','ON','INPUT','FM5','FM6','FM7','FM10','OFFSET','OFF') # So far
                ezca.switch('VIS-'+ optic +'_MN_OLDCCTRL_Y','OUTPUT','FM1','FM2','FM3','FM6','FM7','FM8','ON','INPUT','FM4','FM5','FM9','FM10','OFFSET','OFF')  # Now

• Also, we modified the gain in typeaparams.py, like the following:

# --- #

• at line.134:
  'ETMX':
  {'P':1.0,
  'Y':1.0}
• at line 119:                   
  'ETMX':
  {'P':0.0,
  'Y':1.0}

# --- #

• Please do check the configuration if this is suitable for the interferometer-commissioning work.
