Any input on Cutler-Hammer Starter?

1 t0 S1 k: ~+ s, @) y
1 ~8 ?2 m+ y/ c! E. XTwo  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.
& y4 q4 R3 j- l4 I4 K  oIt is a cycle.

2 L+ o# ]' J, W4 RWe 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.

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.

  |% Y4 J% S# Z! s* M: r/ j3 n7 w% BThe next thing we can think of  is the coil, we took the coil out to have a close look.
7 `8 [9 r' t! H/ T. d4 RThey  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.

# m6 ]5 s, d6 m" DThe coil should be the problem, we ordered two of them. But it will take 5-6 weeks for us to get them.

Do you guys have any input on this issue?

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.
$ Y8 B( ~6 I& p. j2 USince your cutler -hammer works couple times,  I guess 侠客行 is right, or the sealing connection is just worn out.

$ m3 i* D# O/ y4 S* }3 M. s* m也想到这一点，不过这是新装的设备。
检查过触点没问题。
