Two  cutler –hammer advantage  starters are  doing the same thing:
" ?8 m& X- E& B7 K 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: i8 [$ N+ O/ m- r7 J+ F& X
It is a cycle.
- m+ d% b. C  ~9 q9 G" p7 r* l8 {& P) W8 T0 O8 W
We isolate the network control and use the local start and stop only, the problem remains.
9 P1 J$ C9 f% m9 F1 E: SSwap one of the defective buckets with a good one, the new bucket works fine.

1 X! _- W/ i7 H! t9 Z  Z! T) ]
When the problem happened, we observed that  the contactor has a pulling action but will not seal.5 h, k4 a7 ]$ M6 U; `* U& a
Use a terminating screw divers to push in the contactor, it will not seal either.
6 z3 @/ Y7 }- L: x2 ]Confirm 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.. s( ]8 L8 N" p, ?' v

, W) d2 U) X8 \9 i" J+ IThe next thing we can think of  is the coil, we took the coil out to have a close look.( s# C. ]' O- t1 S; q5 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.
3 Z2 H- l% c1 ?! w9 t$ b It is getting better  this time, we have 7-8 times of running before it quit working.
5 B/ E# j6 f- ^" D/ B9 G
! K/ }5 ]% ]9 C' _8 bThe 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./ s" I: G' K7 S% I
Since your cutler -hammer works couple times,  I guess 侠客行 is right, or the sealing connection is just worn out.
