( I6 S, b( M. y8 \Two  cutler –hammer advantage  starters are  doing the same thing:
After start 2-3 times, they will quit working, if you toggle the  start and stop buttons on DCS screen  , you will get another 2-3 running before they quit working again.

We isolate the network control and use the local start and stop only, the problem remains.
Swap one of the defective buckets with a good one, the new bucket works fine.
The problem should be inside the bucket.

" r4 u, X, p0 q4 xWhen the problem happened, we observed that  the contactor has a pulling action but will not seal.
Use a terminating screw divers to push in the contactor, it will not seal either.

The coil should be the problem, we ordered two of them. But it will take 5-6 weeks for us to get them.

有时候主接触点太脏，也会造成启动器无法正常工作

Don't know cutler –hammer advantage  starters very well, but had been worked on AB switch gears for a little while, which has two different coils, one to pull the vacum bottles up which employs larger current, another one uses less current to hold the connection---if the second coil fails, it won't be able to seal the connection.
Since your cutler -hammer works couple times,  I guess 侠客行 is right, or the sealing connection is just worn out.

也想到这一点，不过这是新装的设备。
