have an MP1 that is firing the open I/O only at the 1st floor (terminal floor). so doors will start to close and then open. it will close 1/4 travel, half way or 3/4 of full travel. it gets a signal to open for some reason. its intermittent.
anyone have any ideas how this could be getting this open input and only at the 1st floor?

do you have access to new cards? The IFA card controls a lot of that. but ive also had a travelling cable give me the same sort of trouble only at the first landing. you could also try to swap IF cards. the first one on the left should be the one the controls doors and safety edges. they are interchangeable and simple to swap. ill look at my adjusters manual tomorrow as well.

Think we got it. Embarrassing, but it was the bottom limit. After the 5 yr testing cam must have shifted and would intermittently touch the limit causing the doors to open randomly. Thanks for your help.
