GGOSS Posted April 13, 2006 Report Share Posted April 13, 2006 Hello muganga, I do not know too much about the EWB package however it would appear from your description that you may have neglected to add a 'seal' or 'hold in' contact accross the start button. This would normally be achieved through an auxilary contact from the main contactor. Regards,GGOSS Link to comment Share on other sites More sharing options...
