Two  cutler –hammer advantage  starters are  doing the same thing:
5 M) Z6 i& \& l  y! T' ^3 a7 w! \ 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. % B5 K7 U, v# |5 C: r+ D
It is a cycle.- @7 o2 C! A: {

) t! Q' `. c: F! EWe isolate the network control and use the local start and stop only, the problem remains.
4 Q) e6 s" Y" [1 bSwap one of the defective buckets with a good one, the new bucket works fine.
* G' ^, ]  t! H6 W  NThe problem should be inside the bucket.
3 m9 E2 [" w( }$ W( d3 c. ?9 _& \; a" m; s$ l' c' b. @" v: {
When the problem happened, we observed that  the contactor has a pulling action but will not seal.( b' y* _+ W+ r7 S# h/ `9 t
Use a terminating screw divers to push in the contactor, it will not seal either.
3 n, j. g: S7 c+ U' HConfirm 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.4 X/ I" h* n; V
0 U( R% F1 F% l# g" |
The next thing we can think of  is the coil, we took the coil out to have a close look.8 X! B' S4 z5 P2 q" }; U% q
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.
) I- w/ R- g9 c: c It is getting better  this time, we have 7-8 times of running before it quit working.
# J) X( j: H, `- H2 q) z+ r
% k9 s* [- b* a8 t# K& zThe coil should be the problem, we ordered two of them. But it will take 5-6 weeks for us to get them.
5 u# W& P% n# a+ U$ \7 i# g; U+ \$ W0 j6 q6 }; V2 q, S
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.
% h. }4 W4 ?, [0 W2 aSince 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。
