Any input on Cutler-Hammer Starter?

: {4 v. Q% s, }Two  cutler –hammer advantage  starters are  doing the same thing:
3 H' p4 H2 W9 t' w1 V9 \ 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.
1 [# h8 b, ~, B3 ^% k1 t7 @. uIt is a cycle.

' q. r, d- Y% ~: ~3 j3 ]1 u" NWe isolate the network control and use the local start and stop only, the problem remains.
. I8 @* ?% a) Q2 J8 XSwap 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.
3 {, R" @' u* S" R. e% z0 mUse 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.

; t" b/ ^: ?: u; A$ e4 O. ZThe next thing we can think of  is the coil, we took the coil out to have a close look.
9 N2 C* H! w6 h/ A' I% M5 R8 V- FThey  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.
6 B8 p: s0 B) z$ [& Y3 F4 C It is getting better  this time, we have 7-8 times of running before it quit working.

% k4 G6 c) ^$ e& v! AThe 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.
, r% [5 S) e; V' ?: f4 I9 q; F2 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。
检查过触点没问题。
