The old Miconic 10 controller swap in that 1980s office tower was a night and day difference from start to finish

We pulled an ancient Miconic 10 system out of a 14-story building downtown last spring (the thing was held together with tape and luck). The before was nonstop callbacks - doors hesitating, floors mis-leveling by almost 2 inches. After we dropped in a new G.A.L. controller and re-did the wiring, the first test run was butter smooth. The building manager said he couldn't believe it was the same elevator. Has anyone else here done a controller swap on a unit that old? How'd your commissioning go?

Did you have any trouble with the old door operator interface when you swapped? @emma_smith mentioned the car light power supply issue and that rings a bell - we found the Miconic's backup power relay was still hot even after cutting main power, had to trace it back three floors to a junction box some sparky had tapped into years ago. The G.A.L.'s door logic was totally different too, ended up replacing the whole door operator because the old one ran on a weird hybrid signal that wouldn't talk to the new board.

We did a similar swap on a Miconic 10 from 1987 in a medical building. The old board had burn marks on the back from a capacitor leak. New iControl system fixed all the leveling issues and the door timers are finally sane. Commissioning took a full week because the power supply for the car lights was tied into the old controller and we had to rework the whole junction box.
