Not being super familiar with the DMC, I have a question about the UPS backup unit, this is the one that is a small type UPS much like you would find hooked up to a desktop computer. Are these designed to automatically allow the elevator to rescue down during a power outage? Also what is the preferred way of testing? When mainline is on, the micros witch is N.O. So when I tested the unit I had one side of the microswitch pulled off, dropped power while running between floors and nothing happened. If anyone has the straight line drawing or any other write up please feel free to share, I have the normal prints but they don't show the UPS so I'm not to clear what all is happening. Just another route mechanic trying to keep things running.
