Hi everyone,

this is more or less a generic question regarding the 3300. I know that the 3300 is the Schindler traction MRL with the controller in the top terminal door buck and the 400a is pretty much the same thing but with the controller in a closet.

We are thinking about taking some on and want to know if anyone has successfully maintained them? Anyone know of any tools that can work on these controllers?

We have a ton of 330a's on service but the 330a seems much different than what is on these units.

Any info, advice, or where to get a tool to work on these would be greatly appreciated.

Also, if we were to lose the main processor board for whatever reason would Schindler be needed to install a new one or can you perform learn runs/address board from the LCD?

Thanks in advance!
