Home Forums General Discussion Technical Questions Kone Miprom HS Marathon Door issue

So on an HS like all Montgomery controllers, the open-door signal from the control is DO10, and DO7 is the door close signal. You need to see if the DO10 signal is coming on and go from there. I suggest you tighten connections, and pull the Molex connectors off and spray some cleaner on the pins and re-connect them.
