Have tried draining the cap. Did not work. Have replaced the GCI360, CRIP, CFIRE, CIOACD, CPBHNA and the cables that link the CFIRE, CPBHNA and CIOACD.
I found an old tech article from Schindler back in 2007. There was a version that was produced for about 5 months that had a programming glitch that would not allow phase 2 to reset. Most of these were found on warranty recall. However this elevator is that vintage and shortly after install the building went empty and sat dormant for a decade. A work around was moving it on inspection to a floor other than the main egress landing and releasing it. In theory according to the article it should recall on phase 1 and shut off phase 2..
We will see headed there today to try it
