How the Acorn 180 works

The Acorn 180 curved stairlift operates off the control board shown in this picture. The lift is powered by two 12vdc battery packs that drive the lift along its track. Since this lift is built on a single rail system it also utilizes a second leveling motor to maintain the seat in an upright position. The controller reads data from an encoder on the drive motor shaft to make adjustments to the seat level while traveling on inclines and around corners.

Because of this, the lift has to be programmed to match the track when installed, changing batteries or if it powers off for any reason and the lift is moved manually with the hand crank. Programming of the lift should only be done by a technician who is trained and experienced with the Acorn curved 180 T565 PCB control board program process.

The J3 code and more

Here we have a J3 code with the lift in self-leveling safety mode and traveling in slow speed. This happens when the lift is out of program or has just been programmed and finding its position on the track. If the lift were to go around a corner or on an incline it could possibly cause a seat tilt motion and should not be used until corrected. The J3 code can appear if the batteries have died, have been replaced, or complete power failure from a PCB fault.

Acorn 180 Error Codes & Troubleshooting

The following is a list of error codes and is for information only. The Acorn 180 is a complex lift and should only be serviced by a professional stairlift mechanic.

The 180, Acorn 80 and Bison Stairlifts

The Acorn 180 has evolved over the years from a few different brands and model numbers. Originally developed by Bison Stairlifts and acquired by Acorn in 2007 the lift has also been branded as the Bison 80 and the Acorn 80. While Acorn has kept the original modular rail design the latest 180 has a newer seat design and a few other changes. It’s important to note the older models will have a completely different circuit board, error codes, and batteries.
