We have been quoting and modernizing quite a few US Elevator 3 Board hydraulic microprocessor control systems. In our area US Elevator completed a lot of new hydraulic construction in condos and healthcare facilities. If you still have one of these elevator controllers, there are a few things to consider.
Availability of parts – To our knowledge there are no more new parts for these elevators. While the circuit boards historically have been fairly reliable and robust, when they go, you cannot buy new. You have to install used or go the repair route. We are collecting the old parts and storing them but eventually they will be all gone; used and repaired.
Elevator mechanic domain knowledge – As the years go by, fewer mechanics know how to diagnose and repair these elevator controllers. Those that are good at it were a small group to begin with and are part of an aging population. Add those two together and it's time to think about replacing it with a controller that more elevator mechanics are familiar with. You do not want to have a significant failure that may cause the elevator to be out 8-12 weeks while you wait for parts. In our area[Chicago] we had a "US Elevator Wizard" who worked at Thyssen Krupp. Great with customers and knew this equipment backwards and forwards. He has recently retired and took all of the knowledge with him. When these great elevator mechanics with specific domain knowledge retire, buildings they took care of are put in a compromised position.
Repair options – We have several repair companies who will attempt to repair these solid state boards. Our experience is that it is a 50/50 shot of the repair company resolving the issue that is causing the elevator to malfunction.
Good news – US Elevator used the most popular door operating system, and other parts of their elevator system, so an elevator modernization is a good fit for most companies. Some OEMs[Original Equipment Manufacturers] i.e. Westinghouse, Otis and Montgomery used their own door systems and other parts that create a more challenging modernization.
