Two cutler –hammer advantage starters are doing the same thing:
0 F+ t- U8 g3 j" w( H0 i 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.

When the problem happened, we observed that the contactor has a pulling action but will not seal.: A9 a. T8 t6 x& J( b) g
Use a terminating screw divers to push in the contactor, it will not seal either.
% ]3 d: Y5 ?* t( n l# P, [0 P8 K8 XConfirm 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.3 y% p2 G; w5 h- g( Q* L

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.
