Looking for information on a very strange 5 coil valve original to a Southeasten Elevator controller package from 1979 installed by R&O Elevator. There are no prints on site, and supposedly no prints for the R&O job number in the R&O archives. The down appears to function like a normal 4 coil valve, but the up appears to be very different. The coils are not energized while running up, but rather energize when the car is to stop through a timing circuit. I have been told it is NOT an Esco. Also, one coil is marked "unloader valve". Any info is appreciated.

I do have a picture, but not sure how to upload
