Home Forums General Discussion Technical Questions Tac 32

I am having a issue with the door disconnect. When I change D-26 from a 1 to a 0, it just goes back to a 1. Before this happened, I had to replace the cpua for a separate problem. Any suggestions would be greatly appreciated.

I can't recall for sure. But doesn't a 32 have a physical door cutout switch on the board? Maybe it's hit?

Yeah it could be the DD switch. Work it a little. Maybe stuck or defective

Was this after a new hoistway scan? Have you performed NTSD test at top and bottom? Generic software version 7B I think does not allow you to successfully complete an NTSD test so you would need to upgrade or downgrade, perform NTSD then change d26.

Are changing d26 on ims? If so it should show a message. Like 420 said to learn ntsd or some other reason
