Two  cutler –hammer advantage  starters are  doing the same thing:7 s( @7 Y! k  j% w( _3 _
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.
0 t' @* z: U) N) U0 k+ y2 nIt is a cycle.
# \" X" \% d! M/ q0 N! }0 `3 l# ]. t7 a
We isolate the network control and use the local start and stop only, the problem remains.
$ V2 i6 V( W# ~" WSwap one of the defective buckets with a good one, the new bucket works fine.; `6 D2 [# V5 [! L) H5 H
The problem should be inside the bucket.
) x) l5 d1 ]' d" n6 ~
0 z4 _, V, n, @  n! T& l4 bWhen the problem happened, we observed that  the contactor has a pulling action but will not seal.+ }6 {+ t* V$ u, J* N4 @/ h6 Q5 w
Use a terminating screw divers to push in the contactor, it will not seal either.' t  D" y6 W9 F, p
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# ?3 J( F* F+ A  l

4 R8 X. A! W1 UThe next thing we can think of  is the coil, we took the coil out to have a close look.8 i. P- c4 k$ r/ s7 ]& E. t/ z1 V% ~8 S
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.0 j2 Y. W% O/ f( e. k
It is getting better  this time, we have 7-8 times of running before it quit working.
# B( y0 [) M8 X& d8 Z% N$ B$ n" @% q. Y' V* r
The coil should be the problem, we ordered two of them. But it will take 5-6 weeks for us to get them.
$ d4 z7 G2 C% c2 Q  g7 {, q. u3 W1 H; c
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.) u  N# I4 a!

Since your cutler -hammer works couple times,  I guess 侠客行 is right, or the sealing connection is just worn out.
