Any input on Cutler-Hammer Starter?

  |' u1 u; f7 [1 [9 q/ DTwo  cutler –hammer advantage  starters are  doing the same thing:
: A- {' q( c3 K  q) R  k  g 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.

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.

When the problem happened, we observed that  the contactor has a pulling action but will not seal.

3 f% b* |3 Z1 Z2 dConfirm 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.

The 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.

检查过触点没问题。
