Two  cutler –hammer advantage  starters are  doing the same thing:
) {8 Q% t: b$ l/ A$ v7 l/ 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. : F8 L) Y9 \5 b7 m# N$ f1 e
It is a cycle.9 K# P  @8 f( y" R
$ U, Z2 R0 h  E& w: D6 J+ |
We isolate the network control and use the local start and stop only, the problem remains.
2 ~  y/ @/ [3 @2 @Swap one of the defective buckets with a good one, the new bucket works fine.! e% ?$ x. ?* r6 ~) M8 p4 f7 B# a! K' g
The problem should be inside the bucket.

. |5 ?3 R! ~& q" FWhen the problem happened, we observed that  the contactor has a pulling action but will not seal.0 E* ~$ t; `% L2 g9 u6 \* o. d: J
Use a terminating screw divers to push in the contactor, it will not seal either.
2 J$ g8 E+ Y  g+ }$ uConfirm 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.
& C/ `* E: R* m; O# J- c  Z: V
1 x/ s: F( Q4 d1 z) j5 KThe next thing we can think of  is the coil, we took the coil out to have a close look.
# Q0 p, A! T" i1 {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.+ z: L  `& j  t1 W
It is getting better  this time, we have 7-8 times of running before it quit working. 2 \9 Z' m( [: A- n" E' u
. X5 \* J: ^3 c) q: H0 W
The coil should be the problem, we ordered two of them. But it will take 5-6 weeks for us to get them. 0 K( g0 b7 e3 a7 D

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.
* H1 [% H; Z% I  ISince 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。9 L2 f9 |! H0 w/ u9 c+ U& e
检查过触点没问题。
