We've used Motion on nearly 500 units, traction and hydraulic, and had VERY FEW problems, overall. Most problems can be fixed in the field pretty quickly, or with their phone tech support. Their circuits are comparatively easy to trace, so a lot of techs like them. Boards are available o/n air from Rancho Cordova, CA. I like the flexibility they give us to configure spare input and output channels, and adjust operating parameters in the field. (Compare that to another manufacturer, where I had to get their engineering dept to write new software, with all the frustration and delay that incurs)
Last time I heard, they had something like 40% of the modernization market. For traction elevators, you could go with an MCE M4000, or the new iDrive. They can advise you best, as to what model meets your job specific needs. 916-463-9200.
(MCE, can I have my lollipop now?)
What do these controllers generally cost(ballpark figure)?
BTW the prices these guys are giving are just to buy the controller, the much more expensive part is the labor to put it all in adjust and inspect.
