Any input on Cutler-Hammer Starter?

/ X$ N- A& V1 H6 }1 pTwo  cutler –hammer advantage  starters are  doing the same thing:
; S# `. ?/ P* E+ p  J 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.
( L" i& }# m, g+ HIt 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.
The problem should be inside the bucket.

When 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.
0 i/ Q" _6 ]0 G7 R; c' TConfirm 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.

7 C/ W" Z. k/ z1 ~" s1 IThe next thing we can think of  is the coil, we took the coil out to have a close look.
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.
+ m. u) X  P. f1 E: i It is getting better  this time, we have 7-8 times of running before it quit working.

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.
