The Fujimoto has sensors in the intake path that tell the wash dry unit and replenisher how long to run. The data is relayed using DIN plug (three pin, if I recall correctly)

I have yet to make the interface, but my plan was to build a buffer board to drive the 120V replenshment pumps that I salvaged from a Kreonite processor.

My North American marketed CP31 was wired for 120V service.
Actually the pumps and electronics and drive motor ac input run on a japanese voltage of 100VAc.
There is an oem autotransformer in mine to go from 120 to 100V . Only the heater elements (and maybe the vent fan) run at 120V.
