Acorn 180 – cant complete program cycle.
-
-
I installed an Acorn 180 stair lift for my uncle. The lift worked properly when purchased, the only changes were shorten the top run, remove a hinge track, and lengthen the bottom run.
I have an issue completing the program cycle. It makes it to the bottom charge, then limit, and back to charge. When returning to the top, it shuts down, no power or codes (Everything is dead) about 1′ from the top charge point (which would complete programming.)
Conditions:
1) I have experienced the same conditions (stops in slightly different locations) using the existing batteries as well as a set of Amazon replacement batteries (Both fully bench charged)2) I’m getting proper voltage and polarity at both top and bottom charge points.
3) I programmed the lift with speeds limited to 3 and 4 (vs 3-6) with the same results.
4) There is no debris or rough transitions between tracks
Attempted solutions:
1) Replaced with a new set, fully re-charged (on the bench) Amazon 14.8 Li-Ion batteries – SAME RESULT2) Fully charged (on the bench) the original Acorn Batteries – SAME RESULT
3) Changed the control board – SAME RESULT
4) Changed to a completely different working carriage – SAME RESULT
UNIT SPECS:
T-565 PCB (no switches), (2) Lithium Ion batteries (14.8v), 33V 1.3 ah charger
The lift is a LH outside 90 degree helix, stairs are 40 degrees with a square landing half way. In order to move the lift after it dies, I have to unplug batteries, plug them back in, and begin P1 programming to get it to the top charge point (some times multiple times.) This has been the case with all combinations mentioned above. Is there a trick that I’m missing? I feel like I’m following program procedure to a “T” -

Your ebay account appears dead. I would use any support, since Acorn basically provides none and never returns a call.

hey Brian, I didn’t notice it was you, sorry

Yes, still trying to figure it out

Update – I was able to borrow a pair of known working batteries and confirmed that the batteries are not sufficient. I have a set of original Acorn Lithium Ion and replacement Hubarts Lithium Ion. Does anyone have a source for quality replacement battery packs?

I am wondering if you found batteries. I have the same issue. I did order some off eBay and have been waiting a month for delivery. I am hoping someone might make a YouTube and post it on programming the Acorn 180 so it is easier to understand.

Is there any chance you could make a programming video?

Hello all. There are at least two T565 battery chemistries that work depending on the motherboard: unchipped nicad and chipped lithium of several shapes/battery chargers — contrary to Acorn. In my experience, several error codes are encountered during supposedly “straight-forward” 180 and Acorn 120/130 battery replacement contracts. One client paid me for a battery replacement that (to complete) required fixing (without pay) a micro switch damaged by curry sauce — their stairlift was a dumbwaiter for a takeout food operation, lol.<div>
<div>
For pre- T565 motherboards, I restored some packs to a usable voltage without blowing up lithium packs, as shown on several vlogs. Dont play with unprotected lithium cells and dumb chargers unless you are experienced with small mushroom clouds already. One house in my city recently burned down.
