Actually fixed a Vertitron last night on call. We have a bunch usually in department stores. They seem ok.To me it is a little over the top to really even need a uP on a two or three stop hydro but that is the world we work in.
EC controls look like a MCE clone of the older controls. I think both companies may have been offshoots from the demise of US Elevator. Certainly the EC retains the old power bus naming and relay logic. Their relay board is very similar to MCE except they use 120 vdc instead of 120vac.
I adjusted a few of these about 10 yrs ago. I remember some software issues on emergency power. I also remember some dude from India who I couldn't understand a word he said on the phone. I guess we as Americans can't produce engineers anymore. It is pathetic.
