I am trying to help a family member with their Platinum stairlifts, Horizon stairlift.
It’s second hand and was working fine before it was moved. After installing it they are getting a continuous beep when trying to move down (left) and the error message “End stop”.
If we manually wind it down it goes up (right) with no issues.
It sounds like the sensor on the chair that detects the bottom end stop has got jammed when reinstalling the chair. I don’t know that model but I would suggest removing the chair from the rail and looking for the sensor.
I had a look at my Stannah last night and with the chair at the top of the stairs I could see the slow and stop sensors which were touching the end stop on the rail. According to the wiring diagram there are 3 sensors on the carriage: Right slow, Stop and Left Slow. It is possible that the left slow sensor could just be caught inside the carriage which may prevent the downward movement. Can’t be sure but hope this helps.
I managed to source both an installation manual and video, I have shared it and will try to get over there at the weekend to investigate the sensors and look to set off I can resolve the issue. I really appreciate your time to answer.
