I have a car that will trip the detector edge and reopen every time it gets about 1/4 closed. the funny thing is if i access the car down and run the doors from the door operator switch, it never trips. it is the Kone edges that sit on the back edge of the car sill, and do not move with the door, they are real thin, and they plug into the AMD1 drive, and then the signal goes to the ccbn board on the car and finally to the lce board in the controller. i see the red led on the edge turn on , then it reopens, the funny thing is the led stays red until it get fully open. Am i missing something here? the thing that keeps bothering me is i can't get the unit to fail if i run it manually from the door control buttons. any ideas,
