For a few months I have been trying to track down a manual for MTUs series 45 and series 50 controllers. Both run katolight kassec boards which i have that manual. However the controller has a lot more bells and whistles it can do and Im trying to track down manuals or wiring diagrams for them. Any help would be appreciated. And no ...before you say it....mtu did NOT help. They looked at me a went brain dead before they even looked for a manual. They swore up and down they never had that controller when they even had a catalog on the units.
