Any input on Cutler-Hammer Starter?

Two  cutler –hammer advantage  starters are  doing the same thing:
) {8 Q% t: b$ l/ A$ v7 l/ u 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.

The problem should be inside the bucket.

Use a terminating screw divers to push in the contactor, it will not seal either.

# Q0 p, A! T" i1 {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.
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.
* H1 [% H; Z% I  ISince 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。
检查过触点没问题。
