Two  cutler –hammer advantage  starters are  doing the same thing:
; T+ [! @3 `0 W7 P8 k 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.

We isolate the network control and use the local start and stop only, the problem remains.

8 z( B& \8 Y: x) g2 X! \% zThey  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.

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.

也想到这一点，不过这是新装的设备。
检查过触点没问题。
