) n6 N) g$ A# f) g1 C! XTwo  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.

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.

The next thing we can think of  is the coil, we took the coil out to have a close look.

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.

Do you guys have any input on this issue?

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.
! E( m" q% E; W; sSince 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。
