Jed,
Your profile says your a project executive. Im not sure how we can help you?
The safety edge has a very basic function. When something blocks the recievers view of the light ray transmitter, the safety edge sends a signal to the elevator controller to stop the doors from closing and then re-open the doors.
If your doors are closing with an obstruction in the safety edges view, it could mean you need a new safety edge. But there maybe something else going on as well. I recommend you have a licensed & insured elevator service company come and trace out your trouble and make the nessasary repairs. Keep in mind that you have acknowledged a safety issue with your equipment. If someone were to get hurt while entering the elevator, you are liable for neglecting to provide for the safety to the people who utilize you elevator...
