+ t# N) Z" k6 B$ C& rTwo  cutler –hammer advantage  starters are  doing the same thing:  |0 Y. T5 x* o3 G! d& ?6 l
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. 5 M3 s7 P- E. p4 z5 h+ y
It is a cycle., w* T4 S2 L, m% ^% A; b
$ X; h; u$ H$ w' q$ h* M
We isolate the network control and use the local start and stop only, the problem remains.4 U# ?: d. T4 d5 Z, @' ?
Swap one of the defective buckets with a good one, the new bucket works fine.
& i; {- w) a; K- IThe problem should be inside the bucket.1 G5 ?6 e) ?- b2 g- l1 U

! G- I  n1 q& aWhen the problem happened, we observed that  the contactor has a pulling action but will not seal.7 H1 `; L1 Z9 Q7 ^, f) o/ E
Use a terminating screw divers to push in the contactor, it will not seal either.
0 b4 O8 \, a6 N! TConfirm 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.8 L/ V8 r3 }6 e- q8 l7 Z+ D

The next thing we can think of  is the coil, we took the coil out to have a close look." c8 V. m/ K! V5 O- w/ Z; L
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.
9 M' n9 \$ z' w0 s: D It is getting better  this time, we have 7-8 times of running before it quit working.
; D# f" S: I7 M8 S1 W, r9 n# D
2 j% q+ s  {- jThe coil should be the problem, we ordered two of them. But it will take 5-6 weeks for us to get them. ' S+ z3 t, r" t* k6 |5 ]0 E+ K

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: ~2 t' f% N7 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。
