Clocks, Watches/chime locking cam and warning pin alignment


I am installing a new chime locking cam on my Seth Thomas Grandfather Clock. What is the correct position of the chime warning pin when the locking cam is at 1200? Is this alignment set after the 1/4 hour chimes? Thanks for your help, this is driving crazy! The movement is a Hermle.

warning pin is on the gear that drives the chime fly governor--looking at the front of that gear from the front of the movement the pin  should be stopped, when the chimes shut off, at about a "2 o'clock" position.

same setting for all four chime shut off positions

after the 1/4 hour shut off the chimes on Westminster should just have completed the 4 decending notes for 1/4 after the hour.
