* o6 K& V7 I& R, y& i5 PTwo  cutler –hammer advantage  starters are  doing the same thing:
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.
$ R, C& y) d  ?) H1 s# jIt is a cycle.

We isolate the network control and use the local start and stop only, the problem remains.
Swap one of the defective buckets with a good one, the new bucket works fine.
The problem should be inside the bucket.

; K2 f% G3 o4 R. `6 r: aUse a terminating screw divers to push in the contactor, it will not seal either.
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.

' r' z" H- i- m' ^, l. v, \The next thing we can think of  is the coil, we took the coil out to have a close look.
  k7 T& O- X$ k* }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.
It is getting better  this time, we have 7-8 times of running before it quit working.

$ ?: q! U& P) M- _5 G$ Y+ m7 nThe 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.

也想到这一点，不过这是新装的设备。
