4 c. C9 Y/ ~" j8 ?7 VTwo  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.
It is a cycle.

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.

When the problem happened, we observed that  the contactor has a pulling action but will not seal.

Confirm with TECH support this should be a problem with the control circuit board inside the advantage starter, we  bought two new control circuit boards and replaced the old ones, the problem is still the same.

They  have a fork to pinch inside the two leads to make connection, it is not a good design at all. We soldered  the connection and tried again.

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.
