In need of print showing the brake circuit. None of my versions have it. Diagram RX9-3S7021C or RX1-2S7592J. This controller has both stamped on tag. Assuming one may be for fire service added after the fact.

Serial 33267, sales number 653153


Any help would be greatly appreciated. Only have 60 volts going to brake coil and rectifier checks out good with 90vdc. I'd rather not start cutting every zip tie if I don't have to!

Can send my email address through PM. Thanks in advance.
