I haven’t found an installation manual, but this may be a good programming manual in the post by chaz.
Acorn 180 Installation Manual
Seem to be for the newer controller board I have (Acorn curved 180 T565 PCB control board).
My chair will run fine from the top to near the bottom, but it seem to think it’s at the bottom and slows and stops. It just needs to be programmed, but I can’t get it to the programming mode. The battery was unplugged for a few months, but the memory is supposed to be nonvolatile, so it probably has the old program.
My chair flashes j3 when I drive it below the top charge point. When I hold down all three safety switches on the footrest, it never advances to display U1. It just says E1 all the time. If I power it off and on, it will flash A1, but still doesn’t advance to U1 when holding down the three footrest safety switches. When it moves again, it goes back to J3.
I can’t get it to the P1, so I’ll probably have to have Acorn come program it for me. Frustrating.
If anyone knows how to get past this, please let me know.
