Hey everyone. Working on a Tac32. SE is mis firing. I’ve replaced the transmitter, haven’t replaced receiver. I’ve replaced the SE transmitter board. My Safety edge works correctly. Beam breaks and makes when it’s crossed. My problem is. My laptop IMS shows the beam to be picked when the curtain is operating correctly. From what it appears. Now the doors will open then stay open. When a car call is pressed. Car runs to two. Doors open. Then stay open. Until the beam breaks. Then They will close. Do I have a bad input. And if so is it at the IOD board, Could the door board do this ?

Thanks in advance to all everyone.
