Any input on Cutler-Hammer Starter?

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.
) d! t* ^1 K% J$ Q0 vIt is a cycle.

We isolate the network control and use the local start and stop only, the problem remains.

9 Z! g* ]4 m; B! F$ WWhen 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.

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.

/ ?2 a3 t* _$ D) k0 ~6 X% T也想到这一点，不过这是新装的设备。
检查过触点没问题。
