Two  cutler –hammer advantage  starters are  doing the same thing:
  ^' v" b' G1 A1 P8 f7 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. + A9 }! W6 I& q/ I6 W
It is a cycle.
; p1 L: |+ R3 W3 |. y7 x% g$ P8 C# R" p# ?6 [
We isolate the network control and use the local start and stop only, the problem remains.% S8 C) @+ H8 Z$ ?! {$ f
Swap one of the defective buckets with a good one, the new bucket works fine.
1 s/ W1 T( J* w" d! PThe problem should be inside the bucket.& ]2 O% Z7 M9 Z3 g7 p, B$ O) c

- Z5 W8 s. f2 B2 zWhen the problem happened, we observed that  the contactor has a pulling action but will not seal.1 R! ~; H# X# V% H& }; q
Use a terminating screw divers to push in the contactor, it will not seal either.
6 S( s% s: P8 W, b+ [) p/ wConfirm 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.
; h0 s. e  h* X9 u
! U$ b% m! V. u' v& RThe next thing we can think of  is the coil, we took the coil out to have a close look.0 L) I' K' Z% s. P' q: Q& O
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.' o. d) F% D2 z2 a: Y( V% ^
It is getting better  this time, we have 7-8 times of running before it quit working.
+ Q* K2 v+ y  ^2 A" R
( t2 }7 h: L% _- {3 CThe coil should be the problem, we ordered two of them. But it will take 5-6 weeks for us to get them. % N+ R" H% @! z

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.; g; M6 t3 `5 Z8 G! z3 M' z
Since your cutler -hammer works couple times,  I guess 侠客行 is right, or the sealing connection is just worn out.
