I wonder how do I use this program? I want to interface my XP desktop to the car operating handle contacts of an old Otis elevator. (i'm looking at the elevator's electrical schematic which shows how the car's control switch is wired)
The interface needs to use six relays,three for up & the other three for down. The schematic is for an Otis No. 2A or 3A SOS
Magnet Controller w/ worm gear traction machine 3 phase,3 wire,car switch operation w/ potential switch & operating transformer variable. Relays 1-3 for down direction would have
their contacts connetcted to contacts 1D,A7,4D & 3D.
Relays 4-6 for up would have their contacts connected to
contacts 3U,4U,B7 & 1U. There are three operating speeds in either direction. & the building the elevator is in is 10 stories.
