Any input on Cutler-Hammer Starter?

! Q1 g7 S2 v) t# u* |9 w+ nTwo  cutler –hammer advantage  starters are  doing the same thing:
6 ]( }. N/ j- [3 p 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.
It is a cycle.

2 c) A! t6 D7 Y: vWe isolate the network control and use the local start and stop only, the problem remains.
/ p# Y& Z- E' l  I  |Swap one of the defective buckets with a good one, the new bucket works fine.
The problem should be inside the bucket.

When the problem happened, we observed that  the contactor has a pulling action but will not seal.
/ T" \- c  \" c4 i$ PUse 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.

: X. ^$ L1 P2 a: T+ q+ bThe next thing we can think of  is the coil, we took the coil out to have a close look.
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.
, G8 t3 \' D7 B! v It is getting better  this time, we have 7-8 times of running before it quit working.

The 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.
) a* o6 u0 F9 bSince 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。
检查过触点没问题。
